Secure Data Retention and Geolocation Services

Forget everything you think you know about fulfilling lawful intercept data retention and geolocation requests.


We help telecoms to automate, secure and speed your responses to lawful mass geolocation, emergency call location and criminal investigations requests. While remaining completely compliant.


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We understand the challenges MNOs are facing when dealing with outdated systems and silos that limit the ability to efficiently manage lawful intercept requests and without individual dependencies.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


Improves the way telecoms respond to data retention & geolocation requests

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.

Mobile data collection

Data from network equipment, passive probes (XDRs) including  calls, SMS, data connections, location and flexible to new sources and technologies, such as 5G.

Enriching & integrating data

Mapping between subscriber and current IP address (NAT logs) and integrating with cell databases, device databases, CRM and roaming records (TAP files).

Securing & constraining access

Only authorized users and subset of data is authorized. Logging of all searches and search trails is included.

Eliminate risk of human error

Automate as large part of the process as possible both for efficiency and potential "human factor" errors. Retain data for desired number of days. The database allows for prompt search results that can be viewed on a map or in a table.

Adaptable sources and formats

Locations can be viewed via our intuitive GUI in map or table formats. Reports can be exported in Excel, CSV or XML formats, or in standardized formats such as ETSI TS102 657.

Fast search results & Data retention

The databases are built for fast search-times with search data retained for a specific time period. It is possible to search both on individual subscribers as well as on all traffic related to specific locations.

Automate & streamline requests

Simplifying, automating and increasing responsiveness to lawful requests is made easier with REX from Subtonomy. REX is a dedicated application which utilizes the power of the Subtonomy Platform to efficiently and accurately automate MNOs’ responses to lawful geolocation and data retention requests. The data required by authorities is collected by Subtonomy’s Platform from passive probes, network elements and all underlying subsystems, and preprocessed to make it easier to respond to requests in a timely and efficient manner.

How REX addresses key challenges

Emergency call location

Location data information can be presented in a map view, table view or in exportable formats. Maps are adaptable to improve the topography in rural locations. 

Passive data location

Location updates are sent periodically or, if the phone is idle, when the user changes location area. This is also achieved by monitoring passive data session (such as app push notifications).

REX Case Management

This service provides additional features that enhance the management of searches and improve security, including support for order handling, integration with invoicing systems, generation of reference numbers etc.

REX Token based access

This service enhances self-service security by only granting access to the specific data required for authorized searches. Searches can be restricted to a subset of subscribers or cell towers, or time-limited.

Compliance - above and beyond

REX has been operational for several years in both NATO and non-NATO countries in Europe, demonstrating full compliance with all relevant legislation and regulations. Working as a trusted partner to our customers, Subtonomy has gained deep insight into what is required to efficiently and securely comply with both lawful requests and GDPR.


Adding to our robust compliance framework, Subtonomy is now ISO 27001:13 certified, adhering to the strictest global security standard for information security (ISMS). This certification further establishes our commitment to the highest levels of data security and aligns us fully with EU data retention legislation, Directive 2006/24/EC.
