How every engagement runs

The same four steps whether we are building your API or testing it. You always know what happens next and what it costs.

  1. Step 1

    Scope

    A call, then a written scope with rules of engagement. Nothing starts without signed authorisation.

  2. Step 2

    Test or build

    Delivery against the scope. Critical findings are reported the same day, not saved for the report.

  3. Step 3

    Report

    A one-page executive summary, reproducible proof for every issue, and fixes a developer can follow. Every finding is peer reviewed.

  4. Step 4

    Retest & support

    A free retest within 30 days and a debrief call, then an option to keep us on retainer.

What you can hold us to

Security buyers pay for trust. These are the commitments written into every contract, not marketing claims.

Request a redacted sample report
  • Written authorisation, always

    We never test anything without a signed scope and rules of engagement. Not even a prospect's site to win the sale.

  • Same-day critical findings

    If we find something serious, you hear about it that day by phone, not in the final report.

  • Two sets of eyes

    Every finding and every pull request is peer reviewed before it reaches you.

  • Your data, deleted on schedule

    Findings are stored encrypted, seen only by the people on your project and deleted 90 days after it closes.
