About Thiron

Thiron exists because the tools that show you what attackers can see were built for enterprise budgets, and the small teams who need them most had nothing between guesswork and a five-figure contract.

The problem we kept seeing

Small SaaS and app teams ship fast and rarely have a security person. Every deploy can quietly open a new door: a leaked .env, a forgotten staging subdomain, a spoofable domain, an exposed API. Attackers find these automatically. Founders usually find out the hard way.

What we built

Thiron is an external attack-surface scanner you can run in about 90 seconds with nothing but a URL. It checks your front end and back end across your main site and its subdomains, scores your exposure, and, unlike a raw vulnerability dump, tells you in plain language exactly how to fix each finding. No agent, no credentials, no setup.

How we think about it

• Honest findings. We report only what we actually detect, ranked fairly. No invented urgency.
• Safe by design. Every scan is passive and external, and the scanner refuses to touch anything it shouldn't.
• Useful in five minutes. A security tool only helps if it gets opened. We optimise for clarity over jargon.

Who it's for

Founders, indie hackers, and small product teams (roughly 1–25 people) running a live web product without a dedicated security budget, especially around a launch, a new release, or a customer security review.
