Penetration Testing That Finds What Attackers Actually Exploit
Our CREST-certified penetration testing goes far beyond automated scanning. Real security consultants manually test your web applications, APIs, networks, cloud infrastructure, and mobile apps — using the same techniques that real attackers use. Every finding is fully documented with evidence, a severity rating, and clear guidance on how to fix it.
Secure every layer of your Web Application
We carry out a thorough, manual review of your website and web applications, looking for the most common and the most dangerous security weaknesses. Our testing follows the OWASP Top 10 framework — the industry-recognised list of the most critical web application risks — and goes beyond it where your specific application requires.
Web App Testing
Manual testing of websites and web apps against OWASP Top 10 and application specific risks.
API Testing
Security testing for REST, GraphQL, and gRPC APIs to identify authentication issues, data exposure, access control gaps, and injection risks.
Network Testing
Assessment of internal and external networks to find open ports, weak firewall rules, misconfigured services, and movement risks inside the network.
Mobile App Testing
iOS and Android app testing to review local data storage, server communication, backend exposure, and reverse engineering risks.
Cloud Security Testing
Cloud configuration review across AWS, Google Cloud, and Microsoft Azure.

Full Technical Report
Every vulnerability listed in detail, with a severity rating, step-by-step evidence of how we reproduced it, and specific instructions for your development or IT team on how to fix it.
Proof-of-Concept Evidence
Screenshots, screen recordings, or working code demonstrations that show exactly what an attacker could do if they found the same vulnerability.
Compliance Documentation
Our reports are formatted to satisfy the evidence requirements of PCI DSS, ISO 27001, SOC 2, and other frameworks. You can pass our report directly to an auditor.

FAQ
Q: What method does XeroRisk use when carrying out a penetration test?
A: We follow the OWASP testing guide for web and application testing, the PTES (Penetration Testing Execution Standard) for infrastructure assessments, and our own internal multi-layer review process, which requires a second team to independently check all findings before they are reported. All testers hold current CREST certification.
Q: Will the testing cause any disruption to our live systems?
A: We plan every test carefully to minimise any risk of disruption. In most cases, testing is carried out in a way that is entirely safe for production environments. For higher-intensity tests, we schedule the work during quieter periods or test against a staging copy of your environment. We discuss this with you before any work begins.
Q: How often should our organisation carry out penetration testing?
A: Most major compliance frameworks — including PCI DSS, SOC 2, and ISO 27001 — require penetration testing at least once per year. Best practice, and the standard for most security-conscious organisations, is to test annually as a minimum, plus any time you make significant changes to your systems. Higher-risk environments — financial services, healthcare, critical infrastructure — benefit from more frequent testing.
