Lunar — A free, open breach-search platform by Webz.io that monitors compromised employee credentials, stolen session cookies, and infostealer logs across the open, deep, and dark web. Here's the fastest sensible path from signup to real value.

Getting started, step by step

1. Step 1. Register your organization domain to see current credential exposure
2. Step 2. Review the infostealer-log findings first — those include malware context (machine, malware family), which tells you if a device is still compromised
3. Step 3. Force-reset any account with a stolen session cookie, not just the password — cookies survive password changes
4. Step 4. Add key client domains you manage if you run infrastructure for them
5. Step 5. On enterprise tier, wire alerts into Slack or your ticketing system so exposure creates a ticket automatically

One mistake to avoid

The free tier shows exposure but doesn't push alerts — you have to check. Full automation is enterprise-tier.

Cost to expect

Free tier for breach visibility; enterprise tier adds alerting, integrations, and automation (quoted).
