Do you really know where your IT is vulnerable?
Find vulnerabilities before attackers do
A comprehensive analysis of your IT infrastructure for security gaps — from network and applications to endpoints. With a detailed action plan.
Anonymized reference caseTax advisory firm · Frankfurt, 28 employees+
Starting point
Client data on outdated servers, no active security monitoring, NIS2 obligations unclear.
Solution & result
A complete IT security audit: network, endpoints, applications and a social engineering test.
19 critical vulnerabilities found and fixed, NIS2 readiness achieved, cyber insurance policy taken out.
Unknown vulnerabilities are the biggest security risk
- Most attacks exploit known, unpatched vulnerabilities — most companies don’t know they are affected
- NIS2 and ISO 27001 require regular security audits — without proof, fines of up to €10 million are possible
- Cyber insurers increasingly require audit evidence — without it, there is no coverage
A systematic audit — find, prioritize and fix vulnerabilities
- A complete analysis of all systems: network, endpoints, cloud, applications and human factors
- CVSS-based risk assessment: you know exactly which gaps are critical and what can wait
- A detailed action plan with responsibilities and schedule — no loose ends

Approach
How we work
Scope Definition
Joint definition of the audit scope, objectives and legal authorizations.
Technical Analysis
Automated scans and manual security checks of all agreed systems.
Report & Assessment
Preparation of the audit report with risk assessment and concrete recommendations.
Follow-Up
Review of the implemented measures and an optional retest for verification.
The audit found 19 critical gaps we knew nothing about. Three of them would have given attackers full access to our client data. It was a wake-up call.
Typical Findings
What we find in every second audit
We find these vulnerabilities regularly — even at companies with an active IT department. Most of them have gone undetected for years.
Admin ports exposed to the internet
Network
Unpatched operating systems
Endpoints
Default passwords on devices
Passwords
Missing SPF/DKIM/DMARC records
Public storage buckets
Cloud
Outdated web applications
Application
Our Methodology
Systematic. Complete. Documented.
Our audit process is based on OWASP, NIST, and ISO 27001 — with proven effectiveness.
Reconnaissance
OSINT analysis, footprinting of all external systems, DNS enumeration, Shodan check — exactly how an attacker would proceed.
Vulnerability Scanning
Automated scans with Nessus, OpenVAS, and proprietary tools. OWASP Top 10 for web applications. CVE database matching.
Manual Analysis
Experienced security experts manually check what scanners miss: logic errors, misconfigured permissions, business logic flaws.
Report & Handover
CVSS-scored report: management summary plus a detailed technical section. Closing meeting with a prioritized action plan.
