The Security category collects 122 tech startups indexed on techstartupslist.com. Cybersecurity, identity, and compliance startups. Notable companies in this space include TRM Labs, Vanta, AccessOwl, AeroFS, and Agency — each profile links to the company's own site, lists open roles when their careers page is scrapable, and surfaces team size, founding year, and category tags. Common themes across these Security startups: Security, B2B, SaaS, Cybersecurity, Developer Tools. Filtering by any of these tags in the directory narrows the list further. Geographically, the Security index leans toward San Francisco, New York City and Paris, with the rest spread across remote-first teams and other hubs. Many of these companies came in through the Y Combinator scrape (batches F24, F25, S05, S10); 2 are currently flagged as trending based on recent momentum signals; and the index refreshes daily so this page stays current as funding rounds close, jobs open, and new entrants ship.
