Dark Web Monitoring Your data is traded on forums, markets and Telegram. We watch them for you.
DarkStrata watches criminal forums, marketplaces and leak channels around the clock. When your domains, credentials or session cookies appear, you get an alert with enough context to act.

Where your data surfaces
Most stolen credentials never touch a Tor hidden service. They move through Telegram, invite-only forums, paste sites and automated shops, so we follow the data, not the network: clear, deep and dark web together.
Much of it starts as infostealer logs taken from infected devices. How we handle stealer logs
- Underground forums
- Russian, English and regional-language forums where data and access are traded
- Dark web marketplaces
- Automated shops selling stolen logins and stealer logs per device
- Telegram channels
- Where fresh leaks and lists of stolen passwords now spread fastest
- Breach dumps & combo lists
- Breach data and lists of email-and-password pairs, matched to your domains
- Paste sites & dump repositories
- Open-source (OSINT) channels where data is posted in public
- Ransomware leak sites
- Where gangs publish data stolen from their victims
- Private trading communities
- Invite-only groups where credentials often surface first
- Clear web exposure
- Accidental leaks such as public GitHub repositories and misconfigured cloud buckets
When we find something
Monitoring is only useful if it ends in action. A monthly scan misses the window; we alert while a stolen credential is still fresh, and still revocable.
Detect
Your domains are matched against new stealer logs, password lists and breach data as they surface. Alerts arrive by email, webhook or SIEM feed, with the source, exposure type and first-seen time.
Notify
Affected employees are told privately to reset passwords and revoke sessions. Admins track completion and never see a plaintext password.
Remediate
Resets, revoked sessions and built-in security awareness training close the account-takeover window.

Dark web monitoring: frequently asked questions
What security teams ask before they start monitoring.
What is dark web monitoring?
Dark web monitoring is the continuous surveillance of criminal sources – underground forums, marketplaces, Telegram channels, and stealer logs – for your organisation's exposed data. When your domains or credentials appear, you are alerted so you can revoke access before an attacker uses it. It is early warning for account takeover.
Do you cover the deep web and clear web as well as the dark web?
Yes. Most stolen data never touches a Tor hidden service, so dark-web-only coverage misses the majority of exposures. DarkStrata monitors across the clear, deep, and dark web – including Telegram, invite-only forums, paste sites, and accidental clear-web exposure such as public code repositories.
Which dark web sources do you monitor?
Coverage spans underground forums, dark web marketplaces, Telegram channels distributing stealer logs and combo lists, ransomware leak sites, paste sites, and private trading communities. Fresh infostealer logs from 20+ malware families are the primary source, because that is where account-takeover risk concentrates.
How quickly will we know if our credentials appear on the dark web?
A stolen credential typically appears on a criminal marketplace within 24 to 48 hours of being taken. DarkStrata is built to surface exposures inside that window, with real-time alerts by email, webhook, or SIEM feed – so you act while the credential is still fresh.
Can dark web monitoring feed our SIEM or existing threat-intel platform?
Yes – that is the intended deployment. DarkStrata exports alerts as STIX 2.1, CEF, and LEEF for Splunk, Sentinel, QRadar, and ArcSight, plus webhooks and a REST API, with each alert tagged with the MITRE ATT&CK® techniques its evidence supports. It runs as a complementary credential-intelligence feed alongside platforms like Recorded Future, Searchlight Cyber, or ZeroFox – no rip-and-replace.
We already have an MDR or CTI platform. Do we still need this?
Broad threat-intelligence platforms cover many risk types at once. DarkStrata goes deep on one: fresh, credential-level exposure from stealer logs, mapped to your actual employees and domains. It is designed to run as an additional feed that enriches the stack you already own.
