Dark web monitoring watches the places where stolen data is traded, matches every new record against your domains, people and cards, and alerts you. This guide covers where it looks, what it finds, how to act on an alert and how to choose a provider.
No service can simply search the dark web. Monitoring is collection work: people and machines visit the places where data is traded, turn dumps, posts and listings into records and keep them.
Every new record is matched against what you watch, such as domains, email addresses, names, IP ranges, card BINs and brands, and you hear about it. Old records stay searchable, so you can also look back.
It finds exposure. It cannot delete it: once data circulates, it is copied and re-posted. Monitoring tells you what is out there and where, so you can make it useless.
One-off scan or monitoring
Ten kinds of sources. Some are on Tor, many are not: Telegram, paste sites and public code sit on the ordinary internet, so monitoring has to cover both.
Analysts visit forums, card shops, Telegram, Discord and paste sites every day; scrapers and collectors run around the clock.
Databases and SQL dumps from breaches, and combo lists of email and password pairs, which are often recycled and mixed again.
Everything an infostealer took from one infected computer: saved passwords, cookies, tokens and autofill data, all in one log.
Threads where access, databases and tools are sold and buyers say what they are hunting for. Translated, and re-checked for later replies.
Channels and servers where leaks are dropped, tools are shared and buyers are found. We collect 2,200+ cybercrime Telegram channels, most of them private and invite-only.
Open web, often no account needed: credentials, configuration files and samples pasted in plain sight, and often removed again quickly.
Shops that sell personal and corporate data. A match means that data tied to you is on the market right now.
First the victim announcement, then the leaked archives. Your logins can sit in the leak of a supplier even if you were never attacked.
Payment cards shared for free in dumps and channels, and cards offered for sale on dark web marketplaces.
Cloud storage and databases left open on the internet, readable by anyone who finds them.
GitHub, GitLab, Gists, Postman and 50+ sites found through Google dorking, searched for your domain, brand and internal names.
Seven kinds of findings. Each one comes with the original record, where it was found and when, so you can decide what to do.
Illustration with fictional data: one sample finding per kind, as a monitor would report it.
Combo list shared in a Telegram channel
One reused password can open VPN, webmail and cloud accounts.
Reset it and every reuse of it, then enforce MFA.
Stealer log from one infected computer
With a live session an attacker may not need the password at all, and MFA does not stop them.
Revoke sessions and tokens, reset the credential, investigate the device.
Listing on a card shop
Fraud starts with data: a listed card is about to be used or sold on.
Block or reissue, and feed the hit into your fraud checks.
Russian-language access forum, translated
Access sales rarely name the victim: industry, country and size are the clue.
Check VPN and RDP logins, rotate access, watch for the next post.
Discord server, jobs channel, translated
Plans show up before the incident, while there is still time to act.
Brief the teams that could be approached, and watch the thread.
New domain registration
To your customers, staff and suppliers a lookalike looks like you.
Watch it, and take it down with evidence once it turns hostile.
Public repository of a developer, ana-example
A leaked key that still works opens the door it was made for.
Revoke and rotate the key, then check what it could reach.
A monitor watches your assets, reports only what is new since its last run and hands every finding to the place where your team works.
Every feature has a documented REST API, and next to every search result you can copy the exact request as JSON or cURL. Which plan includes the API and webhooks is on the pricing page. Plans and what they include
Every vendor says it covers the dark web. Six questions show the difference in a trial, ours included.
Our comparison lines up DarknetSearch and other platforms across 33 features, each cell linked to its public source.

DarknetSearch We collect our data ourselves: analysts every day, collectors around the clock.
Combo lists are often recycled. Without dates you cannot tell old from new.
DarknetSearch Every leak carries three dates: published, discovered and added.
You can only act on what you can read: which login, which host, which file.
DarknetSearch The original record, where it came from and why it matched.
Findings belong in your SIEM, SOAR or ticketing system, not in an inbox.

Nobody sees every private chat, and a clean result is not proof of safety.

DarknetSearch splits dark web monitoring by the question you ask. Each page covers one part in depth.
It cannot
Once data circulates, it is copied and re-posted. You make it useless instead: reset, revoke, block, warn.
A clean result means nothing reached the collection, not that nothing leaked. Closed sources change every day.
Invite-only groups open and close. Nobody can promise every source every day.
Chatter is what people say. Sellers exaggerate, listings are recycled and fake records are common.
of the leaked credentials checked in customer environments were still valid, in our own experience. One can be enough, so age and source matter.
How we work
No. Nobody can reliably delete data once it circulates, because it is copied and re-posted. Monitoring tells you what is exposed and where, so you can make it useless: reset passwords, revoke sessions, block cards and warn the people affected.
Not technically: Telegram is an ordinary app on the normal internet. But many cybercrime channels and groups trade stolen logins, stealer logs and tools there, often in private, invite-only groups. That is why monitoring has to include Telegram and clear-web forums.
You choose per monitor, from daily to monthly; new monitors run daily by default. A monitor runs once when you create it and then on its schedule, and the first results cover what is already out there. Lookalike domains have their own intervals, up to every 30 minutes for active threats.
No. Monitoring finds what has leaked and reached the collection, so a clean result does not prove that an account is safe. Closed sources change, and nobody can guarantee every source every day.
Treat it as a security signal. Validate the exposure, reset affected credentials, revoke sessions and tokens if cookies leaked, review access logs and investigate the device behind a stealer log. Then keep a monitor on, so you hear about the next one.
