Endpoint and browser
Independent endpoint, browser-security, and device startups. Not CrowdStrike-class public mega-caps.
9 companies. Catalog last reviewed 2026-08-23. Page copy reviewed 2026-08-23. Next review by 2026-09-23. Ordered by name. No paid placement.
This is the live catalog slice for the Endpoint and browser category. A company appears here only when its primary category matches, and every entry carries a 2024 to 2026 proof-of-life signal recorded with a source link. A full page-unique intro for this category ships in a later polish pass.
How order works. Listings are the full live catalog slice for this primary category, sorted alphabetically by name. This is not a scored quality ranking and there is no paid placement. Aevral is a disclosed house listing under the same rules (coming soon, no pin). See /transparency.
