What does Epieos do?

Epieos is like a digital footprint finder. You give it an email address or phone number and it hunts down where that data shows up online. It’s great at quickly connecting identifiers to platforms and accounts but bear in mind that results have limited depth.

The lowdown: Epieos is a fast, beginner-friendly OSINT tool that excels at turning a single data point into multiple leads but remember to seek verification elsewhere.

How to Use:

1. Go to https://epieos.com/ and choose your search type (email or phone number).

2. Enter your target data and review results including accounts and leaks (Limited results without a paid account). The tool is linked to Have I been pwned? to reveal data breaches.

3. With a paid account, Epieos returns results relating to various different accounts including Facebook, Adobe, Etsy, Strava, Fitbit, Trello, Flickr etc. to name but a few!

4. Pivot by using findings to search elsewhere.
