ABOUT DELVIS
I’m a cybersecurity professional with 13+ years of experience designing and operating security controls across endpoint, identity, cloud, and infrastructure environments. My work has centered on security architecture, detection and response, zero trust access, vulnerability management, and data protection in regulated environments.
I’ve helped teams improve telemetry, harden endpoint and identity controls, and build security processes that are effective without being overly disruptive. I’m especially interested in opportunities where I can bring together security engineering, architecture, and cross-functional collaboration to reduce risk in practical ways.
My background includes experience with Microsoft security and identity tooling, CrowdStrike, SIEM platforms, and compliance-driven environments such as financial services and healthcare. I hold the CISSP and continue building depth in Microsoft security, information protection, and AI security.
Focus Areas:
• Security architecture and design reviews
• Identity and access security
• Endpoint security and EDR/XDR
• SIEM, telemetry, and detection engineering
• Data protection and zero trust
• Vulnerability management and security operations
