Frequently Asked Questions

Is Lunar really free?

Yes. Lunar gives you free visibility into exposure connected to your verified domain.
There are no trials, contracts, or hidden requirements.

Lunar detects exposure tied to your domain across:

  • Infostealer logs
  • Database breaches
  • Combo lists
  • Leaked cookies and sessions


All unified into a single events feed.

Lunar continuously monitors underground sources and can surface new exposure within minutes of it appearing.

Verify ownership of your domain.
Once verified, Lunar shows exposure related to that domain and keeps monitoring for new events.

Only you.
Exposure data is visible exclusively to the organization that verifies the domain.

Both.
Lunar is designed to work for startups, mid-market companies, and large enterprises alike.

Lunar continuously collects intelligence from underground forums, Telegram channels, infostealer sources, and breach-sharing ecosystems.

The ability to see your own exposure is fundamental and intended to remain free.
Advanced features and automation may be offered separately.

Lunar provides context and recommended next steps so your team can respond quickly such as credential resets, session revocation, or further investigation.

No.
Lunar exists because breach visibility should not be gated.
The product is built around returning exposure to its rightful owners.
