UK-Based Penetration Testing

We find critical vulnerabilities
before attackers you do.

OWASP-aligned manual testing for web apps, APIs, and cloud infrastructure. We find the gaps, fix them, retest, and leave you clean.

Everything your attack surface needs

Targeted manual testing that finds what automated scanners leave behind.

01 // PENTEST

Penetration Testing

Adversary-simulated attacks. We exploit vulnerabilities the way real attackers would — then show you exactly how to close each gap.

02 // WEB APP

Web Application Security

Deep testing of auth, sessions, access controls, and business logic. Aligned to OWASP Top 10 and ASVS.

Learn more →
03 // API

API Security Testing

We test for BOLA, broken auth, injection, mass assignment, and data leakage. Your most exposed surface, covered.

04 // VULN

Vulnerability Assessments

Systematic scanning and manual verification of your external and internal attack surface. Identifies exploitable weaknesses first.

// Why XASPRO

Security depth. Developer fluency.

Most firms hand you a PDF and leave. We write the patches ourselves.

Deeper vulnerability discovery

We understand application architecture — so we find business logic flaws and chained exploits that generic scanners miss.

Code-level remediation

Every finding includes specific code fixes. Not "sanitise user input" — the actual parameterised query to use.

We patch and retest

If your team is stretched, we implement the fixes in your codebase and verify each vulnerability is gone.

Compliance-ready reports

Accepted for ISO 27001, Cyber Essentials Plus, SOC 2, and PCI DSS. CVSS scores, PoC evidence, full audit trail.

// Process

Scoping to secure in 4 steps

Fixed scope, fixed price, no surprises.

STEP 01

Scoping

We map your attack surface and agree on testing scope. Clear proposal, fixed price.

STEP 02

Attack Simulation

Manual testing using the same techniques real attackers use. No automated-scan-only reports.

STEP 03

Detailed Report

Every vuln rated by severity. CVSS scores, proof-of-concept evidence, step-by-step fixes.

STEP 04

Retest

We help patch vulnerabilities, then retest to confirm every issue is resolved. Clean report for compliance.
