Practical cybersecurity for South County practices and offices
South Orange County has a large number of medical, dental and specialty practices, along with professional offices, real estate firms and growing companies in Lake Forest, Aliso Viejo and Rancho Santa Margarita.
Many of these organizations run lean IT, often one person or an outside provider. Our audits give owners an independent view of what is protected, what is not and what to fix first, in plain language.
On-site visits run along the I-5 and 241 corridors from our Irvine headquarters; most testing then continues remotely with read-only access.

Questions about cybersecurity services in South Orange County
Do you work on-site in Laguna Hills, Mission Viejo and Lake Forest?
Yes. We visit practices and offices across South Orange County from our Irvine headquarters, and continue most testing remotely.
Can you help our medical or dental practice with HIPAA?
Yes. We assess administrative, physical and technical safeguards, document the risk analysis and give you a remediation plan. See HIPAA compliance services.
We only have one IT person. Is an audit still useful?
Yes. An independent audit gives your IT person a prioritized list and gives the owner a clear picture of risk, without adding staff.
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 offer ongoing security leadership?
Yes. Our virtual CISO service starts at $3,500 per month and covers strategy, policies, risk tracking and reporting.
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.
