Security Audits & Design
Uncover What Automated Scans Miss
Our expert-led audits go beyond checkbox compliance. We map your real attack surface, rank findings by business impact, and design the specific defenses your environment needs.
Our Methodology
From Reconnaissance to Remediation
Every audit follows a structured, offense-informed methodology — the same approach used by professional penetration testers, applied to your defense strategy.
Passive Reconnaissance
OSINT-based attack surface mapping — zero packets sent to your network. We see what an attacker sees before any active testing begins.
Active Discovery
Controlled, authorized scanning and enumeration of your environment. Every system, service, and configuration cataloged.
Gap Analysis
Findings mapped to NIST CSF 2.0, CIS Controls v8, and MITRE ATT&CK. Each gap scored by exploitability and business impact.
Risk Ranking
Prioritized findings with clear severity ratings. We don't just list problems — we tell you which ones to fix first and why.
Remediation & Design
We don't hand you a PDF and walk away. We partner with you to design and implement the specific controls your environment needs.
Verification
After remediation, we verify every fix. Controls are tested against the threats they're designed to block.
Audit Types
What We Audit
Each audit type targets a specific layer of your environment. Most clients start with an AD and M365 audit, then expand based on findings.
Active Directory & Identity Audit
Full AD health assessment — stale accounts, privilege escalation paths, Kerberos configuration, GPO hygiene, krbtgt rotation status, and Entra ID sync posture.
Microsoft 365 Security Audit
Tenant-wide security review — MFA enforcement, conditional access policies, mailbox delegation, admin role sprawl, SharePoint sharing, and compliance score analysis.
Network & Infrastructure Audit
VLAN segmentation review, firewall rule analysis, DNS security, Wi-Fi posture, IDS/IPS configuration, and full network topology mapping.
Endpoint Security Assessment
EDR deployment coverage, patch compliance, local admin policy, USB control, AV/EDR telemetry review, and endpoint hardening gap analysis.
ADA & Web Compliance Audit
WCAG 2.1 Level AA compliance assessment for your web presence — automated scanning plus manual review with scored findings and remediation guidance.
Power & Physical Infrastructure Audit
UPS health assessment, battery configuration review, environmental monitoring, physical access controls, and datacenter/closet security posture.
Framework Alignment
Every Finding Mapped to Industry Standards
Know Exactly Where You Stand
A ThinkOpen audit gives you a clear, ranked picture of your security posture — with a roadmap to fix what matters most.
