Penetration Testing That Finds What Scanners Miss
Manual, expert-led security testing that simulates real-world attacks against your systems. Know exactly where you're vulnerable — and how to fix it.
What Is Penetration Testing?
Penetration testing is a controlled, authorised attack against your systems carried out by a security professional. The goal is simple: find the vulnerabilities an attacker would exploit before they do.
Unlike automated vulnerability scans, penetration testing involves manual testing, creative thinking, and chaining multiple weaknesses together — exactly how a real attacker operates.
At XASPRO, every test is conducted manually by a security professional who also writes production code. That means we don't just identify issues — we understand the root cause and can tell you exactly how to fix them.
What We Test
External Infrastructure
Servers, firewalls, exposed services
Web Applications
Authentication, authorisation, input validation, session management, business logic
APIs
REST and GraphQL endpoints, token handling, data exposure
Internal Networks
Lateral movement, privilege escalation, Active Directory weaknesses
Cloud Environments
AWS, Azure misconfigurations, IAM policy review
Common Vulnerabilities We Find
Our testing is aligned to the OWASP Top 10 and real-world attack patterns.
| Vulnerability | Business Impact |
|---|---|
| SQL Injection | Full database access, data theft |
| Broken Authentication | Account takeover, unauthorised access |
| Insecure Direct Object References | Access to other users' data |
| Cross-Site Scripting (XSS) | Session hijacking, phishing |
| Broken Access Control | Privilege escalation, admin bypass |
| Security Misconfiguration | Information leakage, default credentials |
| Server-Side Request Forgery | Internal network access from external |
| Insecure Deserialization | Remote code execution |
Real-World Example
A SaaS company asked us to test their customer portal before launch. Within the first day, we found:
An IDOR vulnerability that allowed any authenticated user to access every other customer's invoices by changing a single parameter
A broken password reset flow that leaked whether an email address was registered
Missing rate limiting on the login endpoint, making brute-force attacks trivial
All three issues were fixed within 48 hours with our guidance. The platform launched on schedule with a clean security posture.
