What's inside this engagement
Phase by phase.
How a application, api & code testing engagement runs, what happens in each phase and what you see. Exact scope, tier and timeline are fixed in your proposal and SOW.
01Scoping & threat model
Roles, key workflows, integrations and the data that matters are mapped before testing.
You see · Architecture overview and test accounts.
02Authenticated testing
Manual testing against OWASP WSTG / ASVS / MASVS / API Top 10: authorization, business logic, injection, session handling.
You see · A heads-up on any confirmed critical.
03Business-logic abuse
The flaws scanners can't find: broken object-level authorization, workflow bypasses, pricing and entitlement abuse.
You see · Findings in your application's own terms.
04Reporting
Each finding with severity, request/response evidence, reproduction steps and a code-level fix.
You see · A report developers can act on.
05Retest
Fixes verified and the report reissued, where the tier includes it.
You see · An attestation you can share with customers.
Commercials
From first call to final report.
- 01
Scoping call
A practitioner, not a salesperson, walks through targets, constraints and what a good outcome looks like for you.
- 02
Proposal & rules of engagement
A fixed-scope proposal with tier, price and deliverables. Rules of engagement, contacts and out-of-bounds systems are agreed in writing.
- 03
Sign, then start
MSA and SOW are signed electronically and the deposit is paid. Only then does testing begin.
- 04
Execution
Testing runs to the agreed plan. Critical findings are escalated as they are found; you don't wait for the report.
- 05
Report & debrief
An executive summary plus technical findings with evidence, reproduction steps and fixes, walked through with your team.
- 06
Retest
Where the tier includes it, we verify your fixes and reissue the report, so auditors and customers see the issues closed.
Timelines are set per engagement in the SOW.

The Revolut Breach Is a Case Study in Confusing Authentication With Authorization
Revolut disclosed customer data to attackers who spoofed a government agency's email domain for five months. The root cause was not weak email security but a workflow that treated a valid domain as proof of a valid request.
