Choose the security audit path that fits the risk you need to understand.
Not every organization needs the same type of security audit. Use this guide to choose the right starting point for leadership visibility, technical exposure, compliance readiness, Microsoft cloud security, firewall review, or remediation planning.
Technical exposure
I need to know what attackers or internal threats can reach.
Choose this path for internet-facing exposure, internal vulnerabilities, risky services, weak segmentation, missing patches, and exploitable systems.
Microsoft cloud security
I need Microsoft 365, Azure, identity, or email reviewed.
Use this path for MFA, Conditional Access, administrator roles, Exchange Online, SharePoint, Teams, Entra ID, Azure, and cloud governance.
Firewall and remote access
I need firewall, VPN, and perimeter controls reviewed.
Start here when firewall rules, VPN exposure, remote access, NAT policies, logging, segmentation, or legacy access rules need professional review.
Compliance and evidence
I need audit evidence for insurance, customers, or compliance.
This path fits organizations preparing for HIPAA, PCI DSS, SOC 2, NIST, CMMC, ISO 27001, cyber insurance, or vendor security questionnaires.
Self-assessment first
I want to organize my concerns before scheduling an audit.
Use a free self-assessment to identify likely gaps before a professional review. These tools are a starting point, not a replacement for a formal audit.
Already have findings? Move from audit results to remediation priorities.
OC Security Audit can validate risk, clarify business impact, and prioritize remediation. When hands-on implementation is needed, related IT Perfection services can support Microsoft 365, Azure, firewall, endpoint, backup, server, and network projects.
Cybersecurity Audit Services
Know exactly what is exposed, what matters most, and what to fix first.
A security audit should do more than produce a long list of technical findings. It should help your business understand real cyber risk, protect sensitive data, reduce ransomware exposure, strengthen access controls, and prepare for customer, vendor, cyber insurance, and compliance requirements.
OC Security Audit reviews your environment from both technical and business perspectives, helping leadership and IT teams make informed decisions with a practical remediation roadmap.
- Internal network security gaps
- External attack surface exposure
- Microsoft 365 and Azure misconfigurations
- Firewall, VPN, and remote access risks
- Identity, MFA, and account control issues
- HIPAA, PCI DSS, NIST, SOC 2, ISO, and CMMC readiness

Structured Audit Process
A clear path from discovery to remediation.
Every audit is designed to produce useful findings, plain-English explanations, and practical next steps your business can act on.
Discovery & Scope
We define systems, users, networks, cloud platforms, compliance drivers, business goals, and areas of concern.
Asset & Access Review
We identify important systems, permissions, identities, services, firewalls, endpoints, and cloud resources.
Testing & Configuration Review
We review vulnerabilities, exposure, misconfigurations, logging, MFA, firewall rules, and cloud posture.
Risk Prioritization
Findings are ranked by severity, exploitability, business impact, compliance relevance, and remediation urgency.
Audit Report
You receive a technical report with affected systems, security concerns, evidence, and recommended corrective actions.
Remediation Roadmap
We provide an executive summary, practical action plan, and optional follow-up validation after fixes are completed.
Compliance Readiness
Security audits for compliance readiness, customer reviews, and cyber insurance.
Many businesses need audits because a customer, insurance provider, regulator, vendor questionnaire, or leadership team needs proof that security risks are being managed. OC Security Audit helps identify gaps early so your organization can prepare before formal review deadlines.
Healthcare & HIPAA
Support PHI protection, HIPAA Security Rule safeguards, risk analysis, evidence review, and remediation planning.
Customer & Vendor Reviews
Prepare for customer security questionnaires, SOC 2 expectations, NIST CSF alignment, ISO 27001 readiness, and evidence requests.
Payment, Defense & Insurance
Map audit findings to PCI DSS, CMMC, cyber insurance questionnaires, and practical remediation plans.
Industries We Serve
Audit planning connected to the risks in your industry.
Different organizations need different audit priorities. A healthcare clinic, CPA firm, law office, manufacturer, nonprofit, MSP, and real estate company may all need security audits, but the evidence, business risk, and remediation roadmap should match the way they operate.
Healthcare clinics and dental offices often need HIPAA security readiness, Microsoft 365 controls, endpoint protection, backup resilience, and clear evidence that PHI risk is being managed. Start with a cybersecurity risk assessment or HIPAA security readiness review.
CPA firms and tax preparers need stronger client data protection, secure email, access control, backup planning, and IRS WISP support. A practical starting point is an internal security audit, Microsoft 365 email security review, or IRS WISP compliance readiness.
Law firms, real estate companies, nonprofit organizations, manufacturers, and engineering firms often need help with privileged access, cloud permissions, vendor risk, wire fraud exposure, project data protection, cyber insurance readiness, and ransomware resilience.
MSP and MSSP client environments may need independent third-party validation for customer trust, cyber insurance, security governance, and remediation planning. OC Security Audit can connect audit findings with vCISO guidance, vulnerability management, and security governance.
Free Self-Assessment Tools
Use free readiness tools before a formal audit.
Free self-assessment tools help business owners, IT managers, and executives quickly review common control gaps before a customer review, insurance renewal, compliance project, or leadership discussion. These tools are for initial guidance only and do not replace a professional cybersecurity audit, compliance assessment, penetration test, or legal/compliance review.

FAQ
Security audit questions business owners and IT teams ask most.
Answers about scope, vulnerability assessments, compliance readiness, remediation, and local service coverage.
What is a cybersecurity audit?
A cybersecurity audit is a structured review of your network, cloud platforms, users, firewall rules, Microsoft 365 settings, endpoints, data access, logging, and compliance controls. The goal is to identify security gaps before they become breaches, ransomware incidents, failed customer reviews, or compliance problems.
What does OC Security Audit review?
Depending on scope, we review internal security, external exposure, network vulnerabilities, Microsoft Office 365, Azure cloud security, firewall policies, user accounts, privileged access, endpoint controls, logging, backup posture, and compliance readiness for frameworks such as HIPAA, PCI DSS, NIST, SOC 2, ISO/IEC 27001, and CMMC.
Is a vulnerability assessment the same as a security audit?
No. A vulnerability assessment focuses on technical weaknesses such as missing patches, exposed services, outdated software, and misconfigurations. A security audit is broader and can include governance, access control, cloud configuration, firewall review, compliance gaps, business risk, and remediation planning.
Do you help businesses in Irvine, Orange County, Los Angeles, and Southern California?
Yes. OC Security Audit supports businesses throughout Orange County, Irvine, Los Angeles, and Southern California, with remote options available for organizations outside the area.
Can you help after the audit report is delivered?
Yes. We can explain the findings, help your IT team prioritize remediation, support firewall and Microsoft 365 hardening, assist with compliance readiness, and perform follow-up validation after critical fixes are completed.
