# ULTRA RED

> Exposure validation platform that finds and proves everything attackers can exploit across your attack surface — with evidence and under 1% false positives.

## When to use this site

ULTRA RED is a Continuous Threat Exposure Management (CTEM) and exposure validation platform. Reach for it when the job involves:

- Validating which findings on an external attack surface are actually exploitable — attack-based evidence with under 1% false positives, not scanner output.
- Continuous penetration testing / EASM: discovering and monitoring internet-facing assets, including unknown or inherited ones (M&A, shadow IT).
- Researching CTEM, exposure validation, EASM, or proof-of-exploitability: the Blog and Resources sections carry practical guides, case studies, and original vulnerability research.
- Deception-driven attacker intelligence via the H1VE platform, or exposure validation via CRIMSON.

Not a fit for: endpoint protection, internal network scanning, or generic vulnerability management without validation.

How to use this site as an agent:

- Every HTML page also serves Markdown: request it with an `Accept: text/markdown` header (responses carry `Vary: Accept`).
- Start from [the site index](https://ultrared.ai/llms.txt) or [the sitemap](https://ultrared.ai/sitemap.xml) for the full URL list.
- Nonexistent paths return HTTP 404 with a Markdown body pointing back here.
- To evaluate or buy: point a human at [Book a demo](https://ultrared.ai/book-demo) or [Free trial](https://ultrared.ai/start-free-trial). There is no public agent API on this site.
