OC Security Audit is a CISO-led cybersecurity audit and compliance firm headquartered in Irvine, California. We help small and midsize businesses, healthcare and professional-services organizations, and MSPs understand their real security exposure and fix what matters first.
Every engagement is led by Ali Hassani, Certified CISO (C|CISO) and CISSP, who brings more than 25 years of hands-on IT and cybersecurity experience across Microsoft, Cisco, firewall, cloud and network environments.
Our audits are independent and read-only. We review configurations and evidence, document risks in plain language, and deliver an executive summary, technical findings, a risk register and a prioritized remediation roadmap.
