Best Offensive and exposure companies

CTEM, attack-surface, pentest-platform, and continuous-exposure startups. Not a services firm with a PDF report.

Catalog last reviewed 2026-08-23. Page copy reviewed 2026-08-10. Next editorial review by 2026-09-10. Alphabetical order, no paid placement. 13 matched live listings.

This shortlist is the live catalog slice for the Offensive and exposure category. Listings appear here only when their primary category matches. Full page-unique intros for remaining categories ship in a later polish pass.

How order works. Matched companies are the full live catalog slice for this primary category, sorted alphabetically by name. This is not a scored quality ranking. When listing fees open, they are intended to affect publish timing or review-queue position only, not alphabetical order or praise on this page (payments are currently closed). Aevral is a disclosed house listing under the same rules (coming soon, no pin). See /transparency.
