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.

Should OpenAI Face Computer Fraud Charges? Why Liability Runs Through Contracts, Not Hacking Law
Cable panels asked if Sam Altman should be tried for computer fraud. The real liability fight is over negligence, contract terms, and disclosure duties -- and CISOs need to update vendor paper now.

Inside the U.S. Cyber Trust Mark: Who Actually Certifies Your Smart Doorbell
The FCC's IoT label program has been announced so many times that most people assume it already exists. It doesn't — no CyberLAB has been recognized and no product applications are open. What does exist is the full accreditation stack: ISO/IEC 17011 to 17065 to 17025, ioXt as lead administrator, and a registry support-period field that is the most useful procurement artifact this program will produce.

Auditor vs. Assessor: Why the Distinction Is Breaking Down in 2026
The LiteLLM/Delve incident didn't just expose a fraudulent SOC 2 — it exposed a systemic failure in how the industry distinguishes independent auditors from vendor-adjacent assessors. For CISOs making vendor security decisions, the difference is no longer self-evident and must be actively verified.
