Location sharing

Mobile data

HotspotID exchanges data between your device and the server over mobile data when you cannot login on WiFi. (Fingerprinting requires WiFi)


Warning with vibration when a rogue Access Point is detected.

Disable wifi

Turn off WiFi when a rogue Access Point is detected.

HotspotID : Neighborhood watch for WiFi networks

HotspotID monitors the profiles of all the WiFi networks each user connects to. The Access Pointp shows these observations and warns you when suspicious networks are detected.

All WiFi networks are unique

After 3 years research with the SNT(*), we found out that each WiFi Access Point has a unique fingerprint.

HotspotID can uniquely identify each individual WiFi Access Point with a very high degree of certainty and it can detect "rogue" Access Points disguised as legitimate ones

(*) SnT (Interdisciplinary Centre for Security, Reliability and Trust)

Wisdom of the crowds

The more WiFi fingerprints you collect the smarter HotspotID gets.

Each positive fingerprint improves the data and makes it easier to spot anomalies.

Data produced by a mass of legitimate users cannot be faked by a minority of bad individuals.


Just start HotspotID. The rest is automatic (*).

HotspotID fingerprints each WiFi Access Point you connect to and updates our servers. Next, our algorithm analyses the data. The result is sent back to your phone and you are warned if you are connected to a "rogue" Access Point.

(*) With default settings.
