What is a professional security audit? A professional security audit is the most thorough check we offer. We test your website or platform in depth using manual and automated methods, covering login and session handling, forms and inputs, access controls and the common weaknesses listed in the OWASP Top 10. Testing only happens on systems you own and authorise in writing.

Who this is for

Online shops, SaaS products, booking systems and any site that handles customer accounts, payments or sensitive data.

Why this price is worth it

  • Most UK providers charge roughly double for the same work (typically £2,500 – £6,000). We keep prices low on purpose, with no account managers and no hidden extras.
  • Plain English, no jargon: you will understand every finding and why it matters
  • UK-based team in Enfield, serving businesses worldwide
  • Defensive only: we test only what you authorise, and your results stay confidential

Everything included

  • Manual and automated testing of your site or platform
  • Login, session and access control testing
  • Forms, inputs and data handling checks
  • Coverage of the OWASP Top 10 weaknesses

How it works

  1. Scoping call — we agree what is checked and confirm the price in writing.
  2. Authorisation — you confirm in writing that we may test the agreed systems.
  3. Assessment — we run the checks and a person reviews every finding.
  4. Plain-English report — ranked high, medium and low, with the fix for each.
  5. Talk-through and next steps — fix it yourself, ask us for a quote, or add a support plan.
