Identity Theft Intelligence

Terabytes of usernames, passwords, personal information, and confidential documents are for sale and openly exposed on the deep and dark web right now.

Hackers use this data to steal money, hijack accounts, and gather information. 4iQ uses it to prevent identity theft.

We continuously scan the deep and dark web to find compromised data and notify organizations when their consumer and employee identities are exposed — hopefully before more damage is done.

Our Solution

IDTheft enables our clients to monitor identities and receive alerts as soon as any exposures are detected seamlessly through REST APIs. They can also search for exposed identities by domains, brands, and other keywords and reset passwords, stop account takeovers, lock-down networks and protect assets.

In Production @ Scale

4iQ scans open web sources, underground forums, black markets, and remote corners of the deep and dark web to curate the industry’s largest collection of 14+ billion records.

4iQ indexes well-known breaches as well as thousands of unknown exposures and accidental leaks. We remove duplicates, discard fakes, verify data and calculate risk.

For maximum privacy and security, customers only register hashed identities. We hash exposed records we collect, and send alerts as soon as a match is found.

Protecting millions of users, 4iQ today powers some of the largest IDTheft Protection service providers operating in the US and around the world.

Case Study

With the rise in hacks, we were challenged to protect millions of consumer identities across the globe. Now, using 4iQ IDTheft, consumers are alerted in real time if their personal information is compromised and before any harm is done. 4iQ has allowed us to scale with better data and more attributes.
