Central Orange County

Security reviews for the offices at the center of Orange County

Santa Ana is the county seat, with courts, government offices and the law and professional firms that serve them. Costa Mesa adds a mix of corporate offices, retail headquarters, manufacturers and service businesses near South Coast Metro.

Many of these offices have grown over years, so we often find older firewalls, shared administrator accounts, flat networks and servers past end of life. Our audits list each issue by risk and give your IT team or provider a clear order of work.

Both cities are close to our Irvine headquarters, which makes on-site walkthroughs and in-person reviews simple to schedule.

Questions

Questions about cybersecurity services in Costa Mesa and Santa Ana

Do you work on-site in Costa Mesa and Santa Ana?

Yes. Both cities are close to our Irvine headquarters, so on-site walkthroughs and findings reviews are easy to schedule.

Our firewall and servers are several years old. Is that a problem?

Often, yes. Devices past end of support stop receiving security fixes. The firewall security audit and the Active Directory and Windows Server audit identify unsupported systems and rank the risk.

Can you help a law firm protect client confidentiality?

Yes. We review email security, document access, remote access and backups, and help firms show clients and insurers how confidential information is protected.

How much does a cybersecurity audit cost?

The Microsoft 365, Entra ID, Azure, Intune, firewall, Cisco network, Cisco Meraki, Palo Alto, Active Directory, internal and AI security audits are $3,500 fixed. Vulnerability assessments, compliance readiness and vCISO engagements start at $3,500. See the pricing page.

Do you work with nonprofits?

Yes. We help nonprofits protect donor data and meet board, grant and insurance security expectations, with a scope sized to the organization.

Do you also fix the findings?

We stay independent and do not implement our own findings. IT Perfection or your current IT provider can work from the remediation roadmap.

Implementation partner

Need the gaps fixed, not just found?

OC Security Audit stays independent and read-only. If you want hands-on administration, IT Perfection can implement the fixes and support ongoing operations. Your current IT provider can also work from the same roadmap.
