Sr Cybersecurity Engineer - Insider Risk - DLP

Irving, Texas, United States

About

As a Cybersecurity Engineer, I focus on enhancing organizational security by designing and implementing frameworks that incorporate tools like Microsoft Defender, SentinelOne, CyberArk EPM, Mobile Threat Defense, Data Loss Prevention, SafeBreach, ArmorText, Aware, and secure web applications. My strategy emphasizes proactive threat detection, strong identity and access management, and strict compliance to protect enterprise assets. I prioritize Zero Trust architecture, ensuring every access request is verified and least-privilege principles are applied. Using Microsoft Entra ID, I create a unified identity control plane that connects users, applications, and resources, allowing precise access policies based on identity, device health, and environment. To boost endpoint security, I deploy Microsoft Defender and SentinelOne for real-time threat detection and response. CyberArk’s EPM is added to secure privileged access, minimizing unauthorized access and breach risks. Acknowledging the threats to mobile devices, I implement Mobile Threat Defense solutions to counter malware and phishing, ensuring secure mobile operations. Data Loss Prevention systems are crucial for protecting sensitive information from unauthorized access and exfiltration. I use SafeBreach for continuous security validation through simulated attacks, identifying vulnerabilities proactively. ArmorText provides encrypted messaging and file-sharing for secure communication, while Aware enhances security awareness and training, promoting vigilance among employees. Securing web applications is vital. I implement measures to protect against threats like SQL injection and cross-site scripting, ensuring the integrity and availability of web resources. My dedication is to delivering solutions that strengthen enterprise assets, align with industry best practices, and comply with standards. By integrating these tools and methodologies, I help maintain a resilient security posture against evolving cyber threats.
