Is Perimetry Cloud an Intruder alternative?

For monitoring what your domains expose, yes. For vulnerability scanning of servers, cloud accounts, containers or internal networks, no: Perimetry Cloud does not do it.

Does Perimetry Cloud find known vulnerabilities (CVEs)?

It reports known vulnerabilities on exposed services from public data sets, prioritised with the CISA list of exploited vulnerabilities and EPSS scores, without connecting to your services to test them. A scanner that connects can find more.

Why are Intruder's prices not shown here?

Its pricing page builds the price from a base fee and the number of targets; we did not find a fixed amount to quote. See its pricing page for your number of targets.

Key differences

Scanning versus reading: Intruder runs vulnerability scanners against your systems, including authenticated tests of applications and APIs, and internal servers on its higher plans. Perimetry Cloud does not scan your systems: it reads public sources and what your servers already show anyone.
Breadth of what is covered: Intruder covers cloud accounts, containers and internal networks, which Perimetry Cloud does not. Perimetry Cloud covers your domains in depth: e-mail authentication, DNS, certificates and their logs, domain expiry, look-alike domains, suppliers.
How the price is built: Intruder charges a base fee plus a fee per target on Cloud and Pro, and quotes Enterprise. Perimetry Cloud charges a plan with a number of domains, with the subdomains found audited with their domain, prices public.
Agencies: Perimetry Cloud's Agency plans add client workspaces, PDF reports with your logo and a monthly report to each client, for €79 a month and up.

Which one fits you

The two can also work together: they do not look at the same things.
