Mark Jayson Salvador

I am a Senior Cybersecurity Engineer with extensive hands-on experience in both blue and red team operations, vulnerability management, and security monitoring. I have delivered VAPT engagements and managed SIEM/XDR solutions across enterprise environments.

My background includes implementing vulnerability tracking systems, reducing vulnerability counts, and improving response times through coordinated remediation and risk analysis. I have supported compliance initiatives such as ISO 27001 and led security awareness and training sessions.

I have managed deployment and administration of security tools including Stellar Cyber, Splunk, Microsoft Defender, Microsoft Sentinel, and a wide range of network and endpoint security technologies. I also bring strong networking and infrastructure experience from roles in large service and consulting firms.

I hold multiple certifications (CCNA, Security+, Fortinet NSE, CEH, Azure AZ-900, Linux+, ITILv4, Lean Six Sigma Yellow/Green) and I am passionate about building resilient security programs, mentoring teams, and driving continuous improvement in security posture.
