Available to hackers 24x7 and brim-full of data, web applications present a tempting target. Our penetration testing relies on the manual exploitation of vulnerabilities so you get the assessment of business risk that only an expert tester can provide. We combine this with the use of the best automated tools.

All assessments are followed by a comprehensive report, with both non-technical and technical descriptions, alongside recommendations for remediation.

Testing the cycle

Testing the cycle

Securing an application is about the full life-cycle – from development, through the in-life processes right through to de-commissioning. The testing will involve any DevOps methodology that is used by your company. The four areas are:

  • IAST: Interactive Application Security Testing
  • SAST: Static Application Security Testing
  • RAST: Run-Time Application Security Testing
  • DAST: Dynamic Application Security Testing

Our testing methodologies

We tailor penetration testing to your specific web application and have developed robust, yet flexible testing methodologies that will give you peace of mind. The tests are carried out from both the authenticated and un-authenticated perspective and will offer an evaluation of the application's security posture from both valid users and unauthorised users.

  • Scoping and planning
  • Application mapping
  • Automated vulnerability assessment
  • Fault injection testing/fuzzing
  • Authentication testing
  • Session handling/authorisation testing
  • Cross-site request forgery (CSRF)/Clickjacking checks
  • Cookie security
  • Information disclosure observations
  • Post exploitation evidence
  • Report
  • Debrief
