Challenge

The problem

Security reviews happened once a year, immediately before an audit, and findings arrived as a long undifferentiated list. Development continued between reviews, so issues were introduced and discovered many months apart.

Goals

  • Move from an annual audit exercise to continuous visibility
  • Prioritise findings by real business impact rather than raw scanner severity
  • Give developers findings they can reproduce and fix directly
  • Verify that fixes actually resolved the issue
Approach

How we tackled it

  • Scoped, authorised engagements

    Each cycle begins with written authorisation, a defined scope and agreed testing windows.

  • Automated coverage plus manual validation

    Tooling provides breadth; manual testing confirms exploitability and probes business logic that scanners cannot understand.

  • Risk-based prioritisation

    Findings are rated using CVSS and then re-ranked against actual business impact in this environment.

  • Remediation and retest

    Findings include reproduction steps, and each cycle closes by retesting the fixes from the previous one.

Design

Design process

The deliverable itself was designed. Reports are structured so an executive summary answers the commercial question in one page, while engineers get evidence and reproduction steps without wading through narrative.

Technology

  • OWASP ASVS
  • OWASP Top 10
  • CVSS
  • Cloud configuration review
  • Manual application testing

Security considerations

  • Testing conducted only under written authorisation from the system owner
  • Non-destructive techniques by default, with intrusive checks separately approved
  • Findings and evidence handled as confidential material
  • Retesting to confirm remediation before findings are closed
Outcome

What we delivered

A repeating cycle of scoped assessment, prioritised reporting, remediation support and retesting — so security posture is tracked continuously rather than sampled once a year.

Results

  • Continuous visibility replacing a single annual review
  • Findings prioritised by business impact, not raw scanner output
  • Reproduction steps that developers can act on directly
  • Remediation verified by retest before findings are closed

Results describe delivered capability. We publish measured figures only where the client has supplied the data and approved its use.
