Choose the network and data security path that matches your current risk.
Use this decision path to move from a broad security concern to the right OC Security Audit service, free assessment, or implementation conversation. The goal is to help owners, IT managers, and executives understand where to start before risk becomes an urgent incident, audit failure, or cyber insurance problem.
I need to find exposed services, patch gaps, or risky configurations.
Use this path when you need vulnerability visibility, external exposure review, prioritized findings, and evidence that remediation is being tracked.
I need firewall, VPN, DMZ, or perimeter security reviewed.
Choose this path for firewall rules, NAT exposure, VPN access, remote administration, logging, segmentation, and internet-facing services.
I need Microsoft 365, Azure, email, or identity security reviewed.

Security visibility for your business
Practical Cybersecurity Services Built Around Real Business Risk
From firewalls and endpoints to Microsoft 365, Azure, cloud security, backups, user access, and compliance controls, OC Security Audit helps identify the gaps attackers look for and gives your team a clear remediation roadmap.
Network, cloud, endpoint, identity, backup, compliance, and risk controls should be reviewed together. A single weak area can create business exposure even when other tools look healthy.

Assessment Scope
What a Network & Data Security Review Can Include
Each engagement is tailored to your environment, but these are the common areas reviewed for business owners, executives, IT managers, and compliance stakeholders.
Internal Network & Infrastructure
Review the trusted internal environment where most business systems, users, servers, and sensitive data live.
External Attack Surface
Identify what attackers may see from the internet before they attempt to break in.
Firewall, DMZ & Perimeter
A firewall should protect the business, limit exposure, and support secure operations, not just pass traffic.
Users, Passwords & Access
The right people should have the right access, no more, no less.
Email, Microsoft 365 & Cloud
Email and cloud accounts are often the easiest path into sensitive company data.
Backup, Disaster Recovery & Data Protection
Backups only matter if they are complete, protected, monitored, and restorable.
Security Coverage

Endpoint Security
Strengthen endpoint protection, patching, monitoring, encryption, and threat response readiness.
Firewall & Cloud Security
Review perimeter exposure, remote access, VPNs, DMZ design, Azure configuration, and cloud identity risk.
Free Self-Assessments
Use quick self-assessment tools to identify common network, cloud, ransomware, access, and compliance gaps.
Protect & Improve
What We Help Protect and the Gaps We Commonly Find
Many businesses do not realize they have security gaps until a review uncovers them. OC Security Audit helps turn those findings into practical security improvements.
What We Help Protect
Your network, systems, people, data, cloud services, business applications, and recovery capabilities.
- Business networks, firewalls, routers, switches, servers, and workstations
- User accounts, passwords, email systems, Microsoft 365, Azure, websites, and domains
- Remote access, VPNs, customer records, financial data, legal data, and healthcare data
- Backups, recovery systems, security policies, and documentation
Common Security Gaps
Weaknesses that can increase ransomware, unauthorized access, downtime, data loss, and compliance risk.
- Weak or reused passwords, missing MFA, former employees still active, and shared accounts
- Flat internal networks, poor VLAN segmentation, outdated firewall rules, and exposed remote access
- Open ports on public IPs, outdated firmware, unpatched servers, and weak email security
- Missing SPF, DKIM, or DMARC, incomplete backups, and missing network diagrams
