Jason Mark

I am a senior cybersecurity engineer with extensive hands-on experience in vulnerability assessment, VAPT, SIEM/XDR operations, and infrastructure engineering across enterprise environments. I have delivered measurable security improvements—reducing vulnerabilities and streamlining remediation processes—while supporting compliance efforts such as ISO 27001.

My technical background spans security tooling (Stellar Cyber, Splunk, Nessus, Burp Suite), network and cloud infrastructure (Fortinet, Cisco, Azure, AWS, GCP), and systems administration (Windows, Linux, VMware). I combine blue-team and red-team skills with scripting and automation (Python, PowerShell, shell) to operationalize security monitoring, incident response, and vulnerability management.

I am a certified and continuously upskilled professional (CCNA, Fortinet NSE, CEH, Security+, Linux+, AZ-900, ITILv4, Lean Six Sigma) who enjoys training teams, improving security posture, and collaborating with stakeholders to deliver secure, resilient solutions.
