Measured problems
- No enforced Content-Security-Policy: report-only: violations are logged, not blocked
A test re-runs this recording against the agent's current code, so it cannot drift from what the agent does today. The AI write-up step is not shown here; on a live run each written finding cites the facts above, and any it can't back up is thrown out.
What it does
- Checks HSTS, Content-Security-Policy, nosniff, framing protection and Referrer-Policy
- Tells a report-only policy apart from an enforced one
- Counts insecure http:// resources on an https page
- Flags a server header that reveals software versions
What it won't do
- Attack, scan or probe your site — it reads one page as any visitor does
- Find vulnerabilities in your code
- Change your server settings
- Read anything behind a login
Permissions and data
| Tool | Reads | Writes | Deletes | Sends anything out |
|---|---|---|---|---|
| Reads one page's headers and HTML. Every finding is a measurement; no AI model writes anything. | Yes | No | No | No |
What leaves our servers: The page address you give. Nothing is sent to an AI model. Your data is not used to train models.
Approvals and limits
Nothing to approve: it only reads one public page.
One page per run. Measured, so a run uses no AI credits.
