Perimetry Cloud compared
How Perimetry Cloud differs from four services that also look at your security from outside. What we say about them comes from their official pages, read on 12 November 2026, with the sources on each page.
Attack surface monitoring with active tests, application and API scanning
Perimetry Cloud vs Detectify
Detectify discovers your attack surface and tests it with payloads, alongside application and API scanning, for development and security teams; Perimetry Cloud reads what your domains show the world, without testing anything, from a free plan to a few dozen euros a month.
Vulnerability scanning of infrastructure, applications, cloud and containers
Perimetry Cloud vs Intruder
Intruder scans your infrastructure, web applications, APIs, cloud accounts and containers for vulnerabilities, with internal scanning on its higher plans; Perimetry Cloud audits what your domains expose from public data, without scanning them, with public prices from a free plan.
Hosted vulnerability scanners, priced per target
Perimetry Cloud vs HostedScan
HostedScan runs well-known scanners (Nmap, OWASP ZAP, OpenVAS, Nuclei, SSLyze) against the targets you give it, from $39 a month for five targets; Perimetry Cloud reads what your domains expose without scanning them, from a free plan.
Security ratings and third-party (vendor) risk management
Perimetry Cloud vs SecurityScorecard
SecurityScorecard rates organisations from outside for third-party risk programmes, with a free account for your own rating and paid plans on quote; Perimetry Cloud audits your own domains with the fix for each finding and watches your suppliers, with public prices from a free plan.
Which one fits you
They do not do the same job. Start from what you need.
| If you need to | Look at |
|---|---|
| Find and fix what your domains expose (e-mail, DNS, certificates, subdomains, look-alike domains) without anything being tested | Perimetry Cloud |
| Test your own web applications and APIs with real payloads | Detectify, Intruder or HostedScan (our verified active scan is coming soon) |
| Scan servers, cloud accounts, containers or internal networks for vulnerabilities | Intruder; HostedScan for servers and internal networks |
| Rate and follow hundreds of vendors in a third-party risk programme | SecurityScorecard |
| Watch up to 200 suppliers for NIS2, with pre-filled questionnaires, at a public price | Perimetry Cloud |
| Look after many client domains as an agency, with reports in your name | Perimetry Cloud (Agency plans); Detectify Professional and HostedScan Professional for white-label scan reports |
How we compare
Only facts we could read on each service's own pages: prices, plans, how it scans, what it asks before scanning. Nothing from review sites, nothing from memory, and nothing said about what we could not check. Where another service is stronger or better suited, the page says so. Prices change: each page gives its sources and the date we read them.
