Subtonomy REX

Improves the way telecoms respond to data retention & geolocation requests

In today’s fast-paced and connected world, telecoms data has a critical role to play in assisting law enforcement, emergency services and anti-terrorism teams. Since 2006, mobile network operators (MNOs) in the EU/EES have been legally obliged to provide telecoms data when lawfully requested.


However, MNOs face mounting pressure to provide accurate data promptly. The data is often fragmented across a large number of telecoms systems, which have to be searched individually. Supplying it in a usable format is therefore costly, time consuming and prone to human error.

We understand the challenges MNOs are facing when dealing with outdated systems and silos that limit the ability to efficiently manage lawful intercept requests and without individual dependencies.


We're here to change that. 

We blend cutting-edge technology with world-class expertise into usable tools designed to eliminate internal bottlenecks and provide fast results. Are you ready to improve the way you respond to lawful interception requests? Together, we will create a brighter future for the society and ultimately assist law enforcement to save human lives.

"Telenor Norway has recently implemented REX as a solution for handling authority requests. We are very pleased by both the system itself and with Subtonomy as a vendor. REX gives us a completely different workday in terms of easiness of use and query response time. Reports we previously had to wait several hours for are now generated in minutes or even seconds. Subtonomy impresses us by being very welcoming, customer-oriented and solution-focused, with high quality project deliveries and reliable support services."
