Penetration Testing (Pentest) for Web Applications and Infrastructure

What is a penetration test

A pentest is different from an automated scan. A scanner finds known vulnerabilities; a specialist checks whether they can be exploited and how an attacker might chain several small weaknesses into a successful attack. The result is not a list of hundreds of generic alerts but a focused set of issues with proven impact and clear remediation steps.

We follow recognized methodologies: OWASP for web applications, PTES and NIST SP 800-115 for infrastructure.

Aspect	Vulnerability scan	Penetration test
How it is done	automated, recurring	manual and automated, point-in-time
What it finds	known vulnerabilities	vulnerabilities and exploit chains
Confirms exploitation	no	yes, with evidence
When	monthly or quarterly	yearly and after major changes

Web application penetration testing

We test the OWASP Top 10, business logic (price manipulation, race conditions, limit bypasses), authentication and authorization including MFA, JWT and IDOR, API security, cookies and sessions, security headers and file uploads. The APIs behind the application are part of the same scope. We recommend a grey-box approach, with regular user access, as a good balance between coverage and cost, and white-box, with source code access, for critical applications.

Infrastructure and Active Directory penetration testing

We check the perimeter (exposed ports and services, VPN, open RDP or SSH), network segmentation, servers and Active Directory, the main target in most attacks. We also test whether an attacker could reach your backups and whether existing monitoring detects the activity. An external pentest for 5–20 public IP addresses takes 5–10 days, and an internal one covering 100–500 endpoints takes 10–15 days.

What you get and what comes next

The report includes an executive summary for management, a detailed list of vulnerabilities with CVSS score, evidence and recommendation, a testing timeline and, where relevant, a mapping to NIS2, ISO 27001 or GDPR.

After the pentest we can take over ongoing protection through cybersecurity and business continuity and the documentation through NIS2 and GDPR compliance. You work directly with us, and we sign an NDA before the scoping call on request. Request a pentest quote.
