What we cover
Practical, board-ready consulting — no jargon, no surprise invoices.
Web Application Penetration Testing
OWASP Top 10 + business-logic testing of your web apps, APIs, and SaaS platforms. Authentication, session management, injection, access control, and data exposure.
Internal Network Penetration Testing
Simulated internal attacker: we test from inside your network — lateral movement, privilege escalation, domain compromise, and Active Directory weaknesses.
External Infrastructure Penetration Testing
We test your internet-facing assets: firewalls, VPN, email, DNS, and public services. Identifies what an external attacker can reach and exploit.
Microsoft 365 + Entra ID Security Testing
We test your Microsoft 365 tenant: conditional access gaps, admin role sprawl, legacy auth, OAuth grant abuse, and mailbox compromise paths.
Wireless Network Testing
We test your Wi-Fi: WPA2/3 enterprise, guest network isolation, rogue AP detection, and credential capture resistance.
