    Standing slot to talk through design decisions, risk priorities, and audit prep. Same auditor, every week.

Why this exists

The difference between having someone on board from the start, and bringing someone in after two months, five months, or two years of building, is enormous.

You can’t bring an auditor in for two or three weeks and expect them to catch everything. That isn’t the auditor’s fault. It’s the structure.

The subscription fixes the structure.

FAQ

Questions.

Possibly. If you commission a full audit within six months, we apply a 20% reduction, subject to scope, fit, and availability. The subscription does not bind either side to an audit.

Same or next business day during EU working hours. Not for incident response or after-hours coverage.

After the initial three months, month to month with 30 days notice.

The monthly add-on delivers written findings. A formal pentest with documented vulnerabilities, severity, and retest is a separate engagement.
