Security Startups

Young security companies, mapped

The security industry, mapped by companies that are actually alive.

Vendor floors mix booths, vaporware, and quietly dead startups with the companies still shipping. This is a curated, independently verified directory of young security companies, organized by what they build, with a proof-of-life signal on every entry. No pay-for-rank.

From the catalog, 205 verified companies across 13 categories
