The nature of modern cyber threats demands a fundamental shift in how enterprises structure their security capabilities. Today, protecting an organization requires more than a capable IT security team—it demands a unified, cross-functional effort embedded across business units, technology groups, and operational functions.

The Limitations of Traditional Cybersecurity Models

Historically, cybersecurity has been treated as a back-office technical concern, handled exclusively by IT or information security departments. This legacy approach is increasingly insufficient for today’s threat landscape, which is broader, faster-moving, and more business-integrated than ever before.

Organizations now face challenges such as:

• Sophisticated supply chain attacks that target third-party vendors and business partners.
• Ransomware campaigns that cripple operational functions beyond IT.
• Regulatory frameworks that mandate organization-wide accountability for data protection.
• Customer expectations that demand seamless, secure digital interactions across every touchpoint.

When cybersecurity is confined to a single department, organizations face blind spots—gaps in governance, inconsistent security practices, and delayed responses to emerging threats. Cross-functional collaboration has emerged as the essential remedy to these risks. 

Why Cross-Functional Cybersecurity Teams Are Essential

A cross-functional cybersecurity team draws on expertise from multiple departments, creating a coordinated defense posture that aligns with the organization’s broader business objectives. This model enables companies to manage cyber risks holistically, integrating security considerations into every strategic decision.

1. Cybersecurity is a Shared Responsibility - No single team, no matter how skilled, can protect an enterprise in isolation. Business units, operations, HR, legal, finance, marketing, and even the executive leadership play critical roles in maintaining a secure enterprise environment. Cross-functional teams formalize this collective responsibility.

2. Greater Visibility Across the Enterprise - By involving various departments, organizations gain a more comprehensive view of digital risk—ranging from insider threats and supply chain vulnerabilities to customer data privacy and regulatory compliance.

3. Faster, More Coordinated Incident Response - In a cyber incident, time is of the essence. Cross-functional teams streamline communication, reduce bureaucratic bottlenecks, and enable faster containment and remediation by having clear roles and relationships established before an incident occurs.

4. Embedding Security into Business Processes - Security must be embedded into product design, procurement decisions, customer engagement strategies, and operational workflows. Cross-functional teams ensure cybersecurity is addressed upstream rather than being an afterthought.

Structuring Effective Cross-Functional Cybersecurity Teams

Designing an effective cross-functional cybersecurity structure requires careful consideration of organizational needs, operational models, and industry-specific risks. While there is no one-size-fits-all blueprint, certain principles apply universally.

Core Components of a Cross-Functional Cybersecurity Team:

1. Information Security Leadership (CISO Office):
   The Chief Information Security Officer (CISO) or equivalent security leadership should set the strategic vision, establish governance, and oversee security operations with board-level visibility.
2. IT and Infrastructure Teams:
   Responsible for securing enterprise networks, endpoints, cloud environments, and application infrastructure, ensuring that technological defenses are consistently implemented.
3. Business Unit Representatives:
   Liaisons from key business functions—sales, marketing, operations—ensure that cybersecurity aligns with day-to-day operations and customer-facing initiatives.
4. Legal and Compliance Professionals:
   Support regulatory compliance, contractual obligations, privacy mandates, and ensure rapid legal response in the event of incidents or breaches.
5. Risk Management and Internal Audit Teams:
   Provide objective oversight, evaluate controls, and align cybersecurity initiatives with broader enterprise risk management strategies.
6. Human Resources (HR):
   Plays a vital role in building a cybersecurity-aware culture, supporting insider threat programs, and managing security-related employee policies.
7. Third-Party and Vendor Management Teams:
   Assess and manage risks arising from third-party relationships, procurement processes, and supply chain interactions.
8. Communications/Public Relations:
   Ensure timely and transparent communication to external stakeholders and customers during security events, helping to preserve brand reputation.
9. Executive Leadership and Board Representation:
   Offer strategic guidance, allocate resources, and provide decision-making authority, ensuring cybersecurity remains a boardroom-level priority.

Steps for Building a Cross-Functional Cybersecurity Team

1. Secure Executive Buy-In from the Start - Without strong leadership sponsorship, cross-functional teams will struggle to gain influence. Cybersecurity must be elevated as a board-level priority, with executive alignment on its business-critical importance.

2. Define Clear Roles and Responsibilities - Establish formal charters, responsibility matrices (e.g., RACI), and escalation paths to ensure clarity in roles during both normal operations and crisis situations.

3. Facilitate Regular Cross-Departmental Engagement - Routine working sessions, workshops, and tabletop exercises help build working relationships across departments, ensuring the team functions cohesively during real incidents.

4. Align Security Goals with Business Objectives - Security objectives must be directly tied to organizational priorities—whether that’s entering new markets, digitizing customer experiences, or optimizing operational efficiency.

5. Invest in Continuous Training and Awareness - Cross-functional teams thrive on knowledge sharing. Regular training sessions, cross-skilling initiatives, and awareness programs ensure all stakeholders are informed about evolving cyber risks.

6. Use Metrics and Reporting to Demonstrate Value - Security teams must communicate their impact in business language—highlighting risk reduction, operational resilience, and regulatory compliance through dashboards and periodic executive reports.

Overcoming Common Challenges

Some of the most common hurdles include:

• Organizational Silos: Many enterprises suffer from poor interdepartmental communication. Addressing this requires cultural change, incentivized collaboration, and leadership modeling cross-functional behavior.
• Resource Constraints: Balancing business priorities with security demands requires careful planning and resource allocation. Cross-functional teams help by distributing responsibility rather than overburdening security teams.
• Lack of Security Awareness: Not every department is security-literate. Closing this gap through structured awareness programs and continuous learning is crucial.
• Resistance to Change: Shifting from isolated to integrated security practices can meet internal resistance. Transparent communication about business benefits helps reduce friction.

Chatbots have become a fixture in modern workplaces. Whether it’s a quick password reset, help with HR policies, or automated access to internal knowledge bases, AI-powered chatbots are changing the way organizations manage routine tasks. Companies are investing in internal chatbots to reduce support overhead, improve employee experience, and speed up operations.

However, what’s often overlooked in this rapid adoption is a growing cybersecurity risk: internal chatbots can be misused by phishers. As these systems become more capable and more deeply integrated into business infrastructure, they are increasingly vulnerable to exploitation by malicious actors who understand how to manipulate them.

How Phishers Exploit Internal Chatbots

One of the most concerning techniques involves something known as prompt injection. By cleverly phrasing requests, attackers can trick chatbots into revealing sensitive internal data or performing actions they are not supposed to. For example, a poorly configured IT support bot could be manipulated into resetting passwords without proper identity verification. A chatbot connected to customer records might inadvertently leak personal data if prompted in the right way.

There are also subtler ways attackers can abuse these systems. Through a series of seemingly harmless questions, a malicious actor could extract fragmented pieces of information that, when combined, reveal confidential insights about the company. This form of data exfiltration through dialogue manipulation often flies under the radar because it mimics normal user behavior.

More dangerously, in environments where chatbots are allowed to trigger workflows—such as provisioning access, generating reports, or interacting with APIs—a successful phishing attack can have a cascading impact across multiple business systems.

Why Internal Security Controls Fail to Catch This

Traditional cybersecurity tools like firewalls, endpoint protection, and email filters are not designed to monitor chatbot interactions. Since these systems operate internally, often within collaboration platforms like Slack or Microsoft Teams, they fall into a blind spot where typical network monitoring fails to detect abuse.

Moreover, many organizations lack clear security policies around chatbot usage. Access privileges are rarely reviewed, input validation is minimal, and security testing focuses on external threats. As a result, internal chatbots can become an unmonitored entry point that attackers are learning to exploit.

How IT Teams Can Protect Internal Chatbots from Phishing Abuse

Limit Chatbot Access Scope

• Follow least-privilege principles
• Restrict sensitive data access unless absolutely necessary
• Regularly audit chatbot permissions

Implement Input Sanitization and Prompt Filters

• Block suspicious or sensitive prompt patterns
• Employ input validation to reduce prompt injection risk

Add Multi-Factor Authentication for Sensitive Actions

• Require identity verification before executing critical operations via chatbots
• Avoid fully automating sensitive tasks

Regular Penetration Testing and Red Team Exercises

• Include chatbots in security audits
• Simulate phishing and social engineering scenarios

Logging and Monitoring of Chatbot Interactions

• Enable detailed chatbot interaction logs
• Use AI-based anomaly detection to identify unusual usage patterns

Failing to secure chatbots can leave businesses exposed to sophisticated phishing tactics that don’t rely on traditional email attacks. By taking proactive steps IT leaders can stay ahead of this emerging threat.

From SaaS platforms to mobile applications, APIs drive modern services, making them a critical target for cybercriminals and a focal point for security teams. As organizations increasingly rely on cloud-based APIs, securing these interfaces and preventing abuse has become paramount. Inadequately secured APIs can result in severe data breaches, operational outages, financial setbacks, and significant damage to an organization's reputation.

Cloud APIs: Why They're a Target

APIs are essentially digital doors to an organization’s data and functionality. In the cloud, APIs connect services such as databases, authentication layers, billing systems, and third-party integrations. Their growing ubiquity stems from:

• Microservices Architecture: Cloud-native apps rely heavily on API-based communication.
• Mobile and IoT Devices: Nearly all mobile apps and connected devices use APIs.
• Third-Party Integrations: APIs enable partners, vendors, and customers to access services.
• DevOps & CI/CD Pipelines: Automation tools use APIs for deployments, monitoring, and testing.

With APIs acting as the gateway to valuable resources, attackers have found them to be an attractive and often under-protected surface for exploitation. 

Understanding Cloud API Threats and Abuse Vectors

1. Broken Object Level Authorization (BOLA) - Also known as Insecure Direct Object Reference (IDOR), this occurs when an API exposes internal object references (e.g., user IDs) without properly verifying user permissions. Attackers can modify object IDs in requests to access unauthorized data.
2. Excessive Data Exposure - Some APIs return more data than needed, relying on the client to filter it. Attackers can parse and extract sensitive information, even if it’s not intended for display.
3. Lack of Rate Limiting and Throttling - APIs without proper rate limiting are vulnerable to brute-force attacks, enumeration, and credential stuffing. Abusing authentication endpoints can help attackers gain unauthorized access.
4. Injection Attacks - APIs are vulnerable to SQL, NoSQL, XML, and command injections if inputs aren’t sanitized. Since APIs often directly interact with backend databases, the risk is significant.
5. Mass Assignment - When APIs automatically map client-provided data to internal objects, it can allow attackers to overwrite critical fields (like admin status) if the API doesn’t explicitly control which fields can be modified.

Abuse Prevention: Core Principles and Defensive Strategies

1. Implement Strong Authentication & Authorization

• Use OAuth 2.0, JWT (JSON Web Tokens), and mutual TLS.
• Enforce least privilege access using Role-Based Access Control (RBAC).
• Validate scopes and permissions on every API call—not just at login.

2. Input Validation & Output Sanitization

• Enforce strict validation on every input—length, format, encoding.
• Sanitize responses to remove sensitive metadata and hidden fields.
• Prevent parameter pollution and improper serialization.

3. Rate Limiting, Throttling, and Quotas

• Apply rate limits per API key, user, IP, and endpoint.
• Use burst limits to allow occasional spikes but prevent abuse.
• Block repeated failed login attempts and request floods.

4. API Gateway and Web Application Firewall (WAF)

Use a dedicated API Gateway to centralize control, and a WAF for runtime protection:

• Strip suspicious headers.
• Block anomalous request sizes and payloads.
• Monitor for pattern-based or signature-based threats.

5. Logging, Monitoring, and Anomaly Detection

• Log all authentication attempts, data access, and error responses.
• Use real-time alerts for unusual geographies, time-based anomalies, or method abuse.
• Integrate logs into SIEM systems for correlation and incident response. 

Token Management and Secrets Handling

API security is only as strong as how secrets are managed.

• Never hardcode API keys or tokens into mobile apps or front-end code.
• Use ephemeral tokens with short lifespans.
• Implement key rotation and auditing.
• Store secrets in secure vaults like AWS Secrets Manager, Azure Key Vault, or HashiCorp Vault.

The API Security-First Development Lifecycle

Security needs to be embedded at every stage of the API lifecycle—not just after deployment. Here’s how:

1. Design Phase

• Define explicit schemas using OpenAPI or Swagger.
• Use “allow lists” for parameters and endpoints.
• Clearly specify authentication flows and access levels.

2. Development Phase

• Validate every input and enforce schema constraints.
• Avoid excessive privilege assignment in backend logic.
• Mask or omit sensitive data by default in responses.

3. Testing Phase

• Conduct automated security testing using tools like Postman, OWASP ZAP, and Burp Suite.
• Simulate common attacks (SQLi, XSS, token replay, fuzzing).
• Run dependency scans to identify third-party library vulnerabilities.

4. Deployment Phase

• Deploy behind a hardened API gateway.
• Enforce HTTPS and strict CORS policies.
• Use HSTS headers and cookie flags (HttpOnly, Secure).

5. Post-Deployment Monitoring

• Set up dashboards for usage analytics and error rates.
• Monitor token issuance, expiration, and revocation activity.
• Continuously audit for unused endpoints and "shadow APIs."

Secure by Design, Scalable by Default

Cloud APIs represent both innovation and risk. If left unsecured, they become attack vectors that are easy to exploit and hard to detect. But when managed with foresight, APIs can be as secure as they are scalable.

To achieve that balance, organizations must:

• Bake in security during the API design and development stages.
• Rely on automation, monitoring, and analytics post-deployment.
• Educate developers and architects on secure coding practices.
• Treat APIs like any other asset—with the same level of protection, logging, and governance.

The API economy is here to stay. Whether you’re a developer, DevOps engineer, or CISO—your approach to API security will define your organization’s resilience in the cloud era.

Living off the Land (LotL) refers to cyberattack techniques in which adversaries use native, legitimate tools found within a target environment to conduct malicious actions. These tools are typically trusted by the operating system and security controls, making them less likely to trigger alarms or be blocked by antivirus or endpoint detection systems.

Rather than delivering custom malware that may be flagged, attackers leverage built-in utilities such as PowerShell, Windows Management Instrumentation (WMI), certutil, and rundll32 to move laterally, exfiltrate data, escalate privileges, or maintain persistence.

Why Attackers Use LotL Techniques

LotL tactics offer numerous advantages for attackers:

1. Stealth - Since the tools used are native to the OS, they are usually whitelisted and trusted by security software. This allows attackers to blend into normal system activity.

2. Low Detection Rates - Traditional antivirus solutions are often based on signature-based detection solutions, which is ineffective against LotL attacks that don’t involve new binaries or known malware.

3. Reduced Need for Custom Malware - Attackers can accomplish their objectives by using built-in system tools, eliminating the need to develop or install custom malware, thereby reducing the chances of being detected.

4. Evasion of Sandboxing - Built-in tools behave like regular system functions, often evading sandbox and heuristic detection mechanisms.

5. Persistence in Highly Monitored Environments - LotL is especially used in environments with strong perimeter security and endpoint protection. It allows attackers to operate under the radar, even in hardened systems.

Common LotL Tools and Techniques

There are a variety of legitimate tools commonly abused for LotL operations. Below are some of the most frequently used:

1. PowerShell - PowerShell is a scripting language and shell used for system administration. Attackers use it to execute malicious scripts, download payloads, perform reconnaissance, and automate lateral movement.

2. Windows Management Instrumentation (WMI) - WMI allows for local and remote management of Windows systems. It’s used for process creation, information gathering, and even creating persistence mechanisms.

3. rundll32.exe - This utility is used to run functions stored in DLLs. Attackers use it to execute malicious DLL files in a way that appears legitimate.

4. mshta.exe - This tool executes Microsoft HTML Application (HTA) files. Attackers use it to run HTA-based malware or scripts embedded in web content.

5. certutil.exe - A command-line utility for managing certificates, certutil is abused for downloading payloads or encoding/decoding files.

6. Bitsadmin - This is used to create download jobs via the Background Intelligent Transfer Service (BITS). Attackers can download payloads in the background using this tool.

7. Regsvr32 - This tool registers and unregisters DLLs and ActiveX controls. It can execute scripts hosted remotely, bypassing many controls.

Detection and Challenges for Defenders

Detecting LotL techniques is extremely challenging due to their low signal-to-noise ratio. Legitimate administrative activity may look very similar to malicious behavior. However, there are some strategies that can help.

1. Behavioral Analytics - Rather than looking for specific tools or signatures, modern security platforms use behavioral analytics to identify anomalies, such as a user running PowerShell at unusual times or from unusual locations.

2. Endpoint Detection and Response (EDR) - EDR tools can track process creation, script execution, and other indicators that suggest misuse of native tools.

3. Event Correlation - SIEM solutions can correlate logs from different sources (network, endpoints, cloud) to spot patterns that indicate LotL activity.

4. Monitoring Baselines - Understanding what normal activity looks like within your environment allows for quicker identification of anomalies.

Mitigation Strategies

While you can’t remove legitimate system tools, you can limit their misuse through a combination of technical controls and best practices.

1. Application Whitelisting - Use tools like Microsoft AppLocker or Windows Defender Application Control (WDAC) to control which executables and scripts can run.

2. Disable Unused Tools - If tools like PowerShell or WMI are not needed on certain endpoints, disable or restrict them.

3. Implement Least Privilege - Ensure users and processes only have the minimum permissions necessary to function. This prevents attackers from elevating privileges or moving laterally.

4. Enable Script Block Logging - This feature in PowerShell logs all scripts being run, including base64-encoded ones, providing valuable forensic information.

5. Network Segmentation - Isolate critical systems to prevent lateral movement via LotL tools. If an attacker compromises one endpoint, make it harder for them to move elsewhere.

6. Security Awareness Training - Many LotL attacks begin with a successful phishing attempt that gives initial access. It is important to teach staff how to identify phishing emails and suspicious activity.

Living off the Land (LotL) techniques abuse trusted system tools, and using it threat actors can carry out sophisticated attacks while avoiding detection by traditional defenses.

As enterprise networks grow in scale and sophistication, managing them has become increasingly complex. Tasks ranging from configuring routers and firewalls to orchestrating multi-cloud topologies and maintaining security policies, the traditional CLI-based or script-driven methods are time-consuming, error-prone, and require specialized knowledge. As enterprises seek greater agility, accessibility, and automation, a groundbreaking shift is emerging: Large Language Models (LLMs)—like OpenAI’s GPT or Google’s Gemini—are being explored to drive Natural Language Network Configuration (NLNC). This transformative approach enables network administrators, DevOps teams, and even non-technical stakeholders to interact with network systems using plain human language.
 
What Is Natural Language Network Configuration (NLNC)?

NLNC refers to the use of natural language interfaces—powered by LLMs—to configure, manage, and troubleshoot network devices and services. The LLM interprets these commands, translates them into the appropriate configuration instructions (such as Cisco IOS, Juniper Junos, or YAML for automation tools), and executes or recommends changes.

Why LLMs for Network Configuration?

The appeal of LLMs in network operations stems from their ability to:

• Lower the learning curve: Reduce the reliance on domain-specific languages.
• Accelerate task execution: Quickly generate complex configurations.
• Democratize access: Empower broader teams to manage networks securely.
• Reduce human error: Interpret intent with greater accuracy using contextual analysis.
• Enhance documentation and auditability: Translate actions into readable logs and explanations.

How LLMs Understand and Translate Network Tasks

LLMs use transformers—a type of deep learning model trained on massive text corpora—to understand and generate human-like language. For network configuration, specialized tuning or prompt engineering is typically required. Key steps include:

1. Intent Recognition: Understanding the user's goal from plain English input.
2. Syntax Mapping: Mapping the intent to network configuration syntax.
3. Context Awareness: Considering current network topology, device roles, and policy constraints.
4. Code Generation or Command Execution: Generating device- or vendor-specific commands or script
5. Validation and Feedback: Running simulations, presenting previews, or confirming actions with the user.

Architectural Overview

A typical LLM-driven NLNC system includes:

• Natural Language Interface (NLI): The user-facing input field or chatbot.
• LLM Core Engine: The language model responsible for interpreting and generating configuration logic.
• Parser/Translator Module: Converts LLM output into structured configuration templates.
• Network Abstraction Layer: Interfaces with actual devices via APIs, CLI wrappers, or automation tools (e.g., Ansible, Terraform).
• Policy & Compliance Guardrails: Ensure generated configs adhere to organizational policies.
• Feedback Loop: Incorporates monitoring and learning from outcomes to improve future responses.

Benefits to Enterprises

1. Faster Onboarding and Training - New engineers can become productive quickly without deep CLI expertise.
2. Rapid Incident Response - Time-sensitive actions can be described in natural language and executed promptly.
3. Increased Automation Adoption - LLMs reduce the complexity of automation tools like Ansible or SaltStack.
4. Enhanced Collaboration - Cross-functional teams can communicate requirements more clearly and consistently.
5. Auditability and Documentation - LLMs can automatically generate changelogs, human-readable documentation, and explanations for compliance.

Challenges and Considerations

1. Accuracy and Validation - LLMs may hallucinate or produce incorrect configurations; rigorous validation mechanisms are essential.
2. Security Risks - An incorrectly interpreted command could introduce vulnerabilities or outages.
3. Integration Complexity - Mapping LLM outputs to heterogeneous environments with different vendors and protocols.
4. Context Limitations - LLMs may lack full situational awareness unless deeply integrated with telemetry and monitoring tools.
5. User Trust and Control - Administrators may be reluctant to hand over control to an automated agent without clear visibility and oversight.

Strategies for Successful Implementation

• Use a Hybrid Approach: Combine LLM-generated suggestions with human validation for critical operations.
• Domain Fine-Tuning: Train LLMs on proprietary network configurations, logs, and documentation.
• Implement Role-Based Access: Limit what commands can be issued by whom, and log all interactions.
• Establish Guardrails: Use policy enforcement engines to catch misconfigurations before execution.
• Continuous Feedback Loop: Use real-time telemetry and user feedback to refine outputs.

For enterprises striving for agility in a cloud-native, zero-trust world, the adoption of LLM-driven network management provides a competitive advantage.

Hardware Root of Trust offers a powerful, foundational approach to cybersecurity for critical infrastructure. By embedding trust at the hardware level, organizations can significantly reduce the attack surface, improve resilience, and prepare for future threats.

Hardware Root of Trust is a set of unmodifiable, foundational security functions embedded in a system's hardware. These functions form the bedrock upon which all other layers of security are built. Unlike software-based protections that can be altered or bypassed, HRoT is embedded into the physical components of a device, making it far more resistant to tampering or compromise.

HRoT typically includes:

• Secure boot mechanisms
• Device identity and attestation
• Trusted execution environments

These components ensure that a device can verify its integrity before executing any code, authenticate itself securely, and maintain a trusted computing environment throughout its lifecycle.

Why HRoT Matters for Critical Infrastructure

Critical infrastructure often operates with legacy systems, long lifecycles, and increasing interconnectivity—all of which make them attractive targets for cyber attackers. Traditional software-based security mechanisms are insufficient in these contexts, where attackers often aim to gain persistent and undetectable access.

HRoT mitigates these risks by:

• Establishing trust at the hardware level, making it extremely difficult for attackers to compromise systems undetected.
• Enabling secure device provisioning, which is essential when deploying large numbers of connected devices across geographically dispersed locations.
• Providing a foundation for system recovery and resilience in the event of a breach.

Use Cases in Critical Infrastructure

Energy and Utilities: Smart grids and industrial control systems rely on trusted communications and operations. HRoT can prevent malicious firmware updates and authenticate legitimate devices.

Transportation: Connected and autonomous vehicles depend on trustworthy navigation and control systems. HRoT ensures secure communication between vehicle components and infrastructure.

Healthcare: Medical devices and health information systems must be protected against tampering and unauthorized access. HRoT helps secure patient data and device functionality.

Telecommunications: 5G and next-generation communication networks require secure endpoints and base stations. HRoT enables hardware-level authentication and secure key storage.

Technical Components of HRoT

• Secure Boot: Ensures that a device boots only using trusted software by verifying digital signatures against a hardware-embedded certificate.
• Trusted Platform Module (TPM): A specialized chip that securely stores cryptographic keys and supports secure generation and attestation.
• Hardware Security Module (HSM): Used in data centers and infrastructure components to manage and protect digital keys.
• Firmware Measurement and Attestation: Verifies the integrity of firmware before and during system execution.

Best Practices for Adoption

• Design for Security: Integrate HRoT at the design phase of new systems rather than as an afterthought.
• Standardize Protocols: Adopt industry standards such as NIST SP 800-193 and the Trusted Computing Group specifications.
• Conduct Risk Assessments: Identify the most critical systems and prioritize them for HRoT integration.
• Monitor and Update: Regularly verify and update firmware, and monitor devices for signs of compromise.
• Collaborate with Ecosystem Partners: Work with vendors and regulators to ensure end-to-end trust in the supply chain.

As threats become more sophisticated, HRoT will play a central role in defending digital infrastructure. For more information on cybersecurity solutions, contact Centex Technologies at Killeen (254) 213 – 4740, Dallas (972) 375 – 9654, Atlanta (404) 994 – 5074, and Austin (512) 956 – 5454.
