Know where you have been

The Hotspot ID™ notifications show details of all fingerprint check results.

The notifications keep you informed about the actual fingerprint check results for each WiFi connection.

 will trigger a long vibration as a warning and will Turn off WiFi. (Configured in Settings)

Set it up the way you want

Automatic Fingerprinting

This is part of the “Set it & Forget it” mode. In combination with the security settings, Automatic Fingerprinting will do all the heavy lifting for you.

Location sharing

We use your device’s location data (anonymised) as the Access Point location.


Mobile data

Hotspot ID™ 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.

Hotspot ID™ : Neighborhood watch for WiFi networks

The Hotspot ID™ App w​orks in the background to fingerprint​ (1)​​ all WiFi connections. This data is relayed to the Hotspot ID​s​erver, ​where it is logged and our algorithm (2)​ checks it against known​ Wi-Fi attack scenarios (3)​ . The fingerprint check results form the basis of the reputation rating for all Access Points in the system.

All Hotspot ID™ users are active participants in wifi security surveillance, to the benefit of the full user community.

  • (1)​ . The Fingerprinting process registers all new AP the app sees and checks the fingerprints for AP already in the DB. Auto-fingerprinting can be managed in the app settings.
  • (2)​ Research partner: I​nterdisciplinary Centre for Security, Reliability and Trust (SnT) ​at the University of Luxembourg (S​nT​- w​​.
  • (3)​ The fingerprint check tests for the following EVIL TWIN (ET) attack scenarios:
    • REPLACEMENT​(S​POOFING)​: A legitimate AP is replaced by the ET
    • COEXISTENCE​(R​OGUE AP)​: The ET and legitimate AP coexist in the same location.
    • REMOTE CLONE: T​he ET is setup in a different location
    • AD HOC CLONE: T​he ET is created on-the-fly by answering probe requests from target device looking for a connection

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

Wisdom of the crowds

The more WiFi fingerprints you collect the smarter Hotspot ID™ 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 Hotspot ID™. 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.


Certified Access Points

Access Point Certification​(APC) is a subscription based service whereby Hotspot ID™ verifies the ownership of a WiFi Access Point.

Access Point Certification improves user security as follows :
● Wifi attack scenarios can be detected with higher reliability.
● Certified Access Points​ are clearly identified in the Hotspot ID™​ app. Users can easily verify the AP owner details.

This service will be offered commercially this summer. In the mean time if you are interested please contact us at
