How long does a security test take?

Last reviewed 2026-09-30Written by Jacob Masse, TrazTech Inc.

For a small AI-built app, plan one to three weeks from the first call to the report: a few days to scope and book, two to five days of testing, and two to three days to write the report. Add one to two weeks to fix and retest. Book three to four weeks before your launch date.

A typical timeline

If you are in a hurry

Ask for critical findings the same day, and be ready with accounts and access on day one. See what to give the testers.

What slows a test down

• Access not ready. Testers waiting for accounts or a staging URL burn paid days. Have everything on the preparation list ready before day one.
• Scope changes mid-test. Adding a feature halfway means re-planning. Freeze the scope for the test window.
• Deploys during testing. A release that changes the app under test can invalidate findings. Pause risky deploys or tell the testers.
• Slow fixes. The retest window is often 30 to 90 days. Fixing late can mean paying for a second retest.

The fastest engagements share a pattern: a clear one-page description of roles and data, a staging copy that mirrors production, a technical contact who answers within hours, and critical findings fixed while testing continues on the rest.
