About

pentest.fyi is a free directory of penetration testing companies worldwide. We currently list 7,599 companies across 101 locations.

The directory is built to help organisations find the right security partner for their needs. Whether you're looking for a local firm or a specialist in a particular area, you can search by location, services offered, certifications held, and company size.

How it works

We use sophisticated web crawling and data enrichment pipelines to discover and catalogue penetration testing companies around the world. Each company listing is enriched with details including services provided, certifications held, notable clients, employee count, and other relevant information — all kept up to date through regular automated refreshes.

Missing or incorrect?

If your company is missing or any information is incorrect, you can submit your company using the button in the navigation bar. We'll review and add it to the directory.
