One cybersecurity partner for offices across Southern California
Many Southern California businesses run several offices across Orange County, Los Angeles, the Inland Empire and San Diego. OC Security Audit reviews every location against the same standard, so leadership gets one picture of risk instead of several.
We are headquartered in Irvine. On-site work covers kickoff meetings, network and server room walkthroughs and in-person findings reviews. Most technical testing runs remotely with read-only access, which keeps travel off your invoice.
