Automated penetration testing for UK businesses

Yrzo AI is a UK-based automated penetration testing service that scans your website for security vulnerabilities using the same techniques professional penetration testers use manually. Every scan runs 44 checks across the OWASP Top 10, including SQL injection, cross-site scripting (XSS), insecure direct object references (IDOR), JWT authentication flaws, server-side request forgery (SSRF), and CORS misconfigurations — then delivers a plain-English report with exact fixes.

What is a penetration test and why does your website need one?

A penetration test (pentest) is a simulated cyberattack against your website or web application. A security professional — or in Yrzo AI's case, an AI agent trained by one — attempts to exploit vulnerabilities the way a real attacker would, then reports what was found and how to fix it. Under UK GDPR and the Data Protection Act 2018, organisations that process personal data are required to implement appropriate technical security measures. A penetration test is the most direct way to verify those measures actually work. Fines for data breaches caused by inadequate security can reach £17.5 million or 4% of annual global turnover, whichever is higher.

How does Yrzo AI compare to a traditional penetration test?

Traditional penetration tests require weeks of scheduling and a significant budget. Yrzo AI delivers the same depth of web application security testing from £149 — no retainer, no enterprise contracts, results the same business day. Every check is based on real offensive security methodology — not a generic scanner that flags informational headers as critical. The service was built by a team of UK penetration testers with 14 years of hands-on experience finding vulnerabilities in production systems across the UK.

Which security checks does Yrzo AI run?

Yrzo AI runs 44 security checks across six categories: core security (CSP, HSTS, SSL/TLS, cookie flags, email spoofing protection via SPF, DKIM, and DMARC), discovery (subdomain enumeration, admin panel exposure, backup file scanning, directory bruteforce, port scanning, technology fingerprinting), injection attacks (SQL injection, XSS, command injection, XXE, NoSQL injection, LDAP injection, SSTI, path traversal), advanced attacks (JWT attacks, SSRF, CSRF, host header injection, cache poisoning, OAuth flaws, WebSocket security), intelligence (sensitive data exposure, API security, business logic flaws, WAF detection, IDOR, DNS zone transfer, GraphQL introspection), and access hygiene (authentication testing, rate limit testing, dependency audit, open redirect, robots.txt review, file upload testing, session expiry, error handling).

Is Yrzo AI suitable for small businesses?

Yes. Yrzo AI was built specifically because small and medium-sized UK businesses rarely get proper security testing — the cost and complexity of traditional pentests puts it out of reach. Whether you run an e-commerce store, a SaaS product, a law firm, or a healthcare platform, if your website handles customer data, you need to know whether it can be compromised. Yrzo AI gives you that answer without the enterprise price tag.
