About PRISIMM-Audit

PRISIMM-Audit is the crawler behind PRISIMM's agent-readiness audits. If you have seen it in your logs, this page explains what it was doing, how it behaves, and how to opt out.

How it identifies itself

Audit requests carry this user agent:

PRISIMM-Audit/1.0 (+https://prisimm.com/audit)

PRISIMM is in pre-release, so you are unlikely to have seen it yet. An earlier AISC-Audit-Fetch/1.0 string belongs to the same service under its previous name and is being retired. If that is what you saw, this page still applies and the opt-out below still works.

What it does

When an audit of a domain is requested through PRISIMM, PRISIMM-Audit reads publicly available pages and signals for that domain: robots.txt, sitemaps, structured data, agent discovery files, TLS and DNS configuration, and a sample of pages. It is read-only. It does not log in, submit forms, or access anything that is not publicly available.

How it behaves

These are the rules PRISIMM-Audit operates under.

• It honours robots.txt under RFC 9309, including rules addressed to PRISIMM-Audit by name, path patterns, and wildcard groups. robots.txt is fetched before anything else.
• It stops when asked. A site that responds with HTTP 429 or 403 is treated as refusing, and no further requests are issued to it in that audit.
• It is bounded. Audits run with capped request counts and timeouts.

How to opt out

Block PRISIMM-Audit in your robots.txt, which is honoured automatically:

User-agent: PRISIMM-Audit
Disallow: /

Or send a do-not-scan request through our contact form, and we will exclude your domain.
