LAWFUL DISCLOSURE FOR TELECOM OPERATORS, FROM INVESTIGATIONS TO SEARCH AND RESCUE

Your network already holds the answer. REX gets it out in seconds.

Telecom operators use REX to answer the requests that cannot wait: lawful disclosure inside the EU's 8-hour deadline, and Search and Rescue location requests when someone is missing. On premise, ETSI aligned, audited end to end.

8 hours

The EU e-evidence deadline REX is built for

km² → m

A Search and Rescue area narrowed from hundreds of square kilometers to meters

On premise

The data never leaves the CSPs environment.

ISO 27001:2022

Certified information security management

Two kinds of request. REX answers both.

The request has  a deadline

Lawful disclosure, data retention, quick freeze, IP tracing and e-CODEX delivery, handled in one system with the audit trail intact.

​

  • EU e-evidence & e-CODEX

  • Automated Data Retention

  • Data Quick Freeze

  • IP address tracing

  • Case Management System

  • Lawful location intelligence

​

The request has a person

A Search and Rescue location request, answered from the data your network already produces, in 30 seconds across every source you have connected.

  • REX for Emergency Response

  • The rescue chain

THE CHALLENGE

Why these requests are hard to answer today

GROWING DATA VOLUMES

5G, IoT and multi-service networks generate more than legacy retention systems were built to hold.

COMPLEX REGULATIONS

ETSI standards and cross-border frameworks such as e-CODEX move faster than most compliance stacks.

FRAGMENTED SILOS

The answer sits across billing, network, CRM and probe systems that were never meant to be queried together.

READY AT 03:00

Neither kind of request arrives in office hours, and both are judged on the time they took.

ONE PLATFORM

One data layer for lawful disclosure and Search and Rescue

REX aggregates the data your network and support systems already hold into one layer, and answers both kinds of request from it. What changes is who is asking, on what legal ground, and where the answer goes.

DATA SOURCES REX CAN CONNECT

Mobile Signaling

CDRs / billing

Passive probes

NAT / IP logs

Roaming records

Timing Advance

MLC

CRMs

Cell inventory

REX - aggregated, enriched, access controlled, logged

One query. Every connected source. One consolidated answer.

To the authorities

ETSI TS 102 657, the national variant, delivered over e-CODEX, inside the 8-hour deadline, with the full case record.

To the rescue team

A position in their map system in 30 seconds, with scoped, time-limited, revocable access for the crew in the field.

Data source agnostic

REX connects whichever sources you run today, from billing CDRs and passive probes to NAT logs, roaming records and cell trace data, and maps them into one view.

Enriched intelligence

Network records enriched with geolocation, cell inventory, CRM and map data, so a record becomes a position.

Controlled access

Every search logged with who asked and on what grounds. Scoped, time-limited access for authorities and rescue crews.

PROVEN IN FIELD

Trusted by leading CSPs

LAWFUL DISCLOSURE

Reports we previously had to wait several hours for are now generated in minutes or even seconds.

Frequently Asked Questions (FAQ) on REX

Your Questions, Answered.

We understand that data retention involves complex technical, legal, and security details. To provide clarity, we've gathered straightforward answers to the most common questions about the REX platform, its capabilities, and its compliance.

  • REX is built for mobile network operators (MNOs), broadband providers (ISPs), and communications service providers (CSPs) across Europe. It handles lawful disclosure obligations regardless of network type or size, including 4G, 5G, and fixed-line environments.

  • REX is deployed on-premise within your own infrastructure, ensuring complete data sovereignty. Sensitive subscriber data never leaves your legal and physical control, which is a hard requirement under GDPR and national data protection laws.

  • Implementation typically takes 3–6 months, depending on the number of data sources, their complexity, and your team's availability. REX is designed for parallel deployment — technical integration, testing, and operational training run simultaneously rather than sequentially, compressing time to compliance where possible.

  • REX integrates with your existing OSS, BSS, CRM, billing, and storage systems via open APIs. Rather than pulling data live from your production systems — which slows everything down and risks network stability — REX mirrors your data into a dedicated compliance layer. This means every lawful query runs against the mirrored copy, keeping your live network untouched and delivering results in seconds. No full system replacement required.

  • REX is built to address EU e-Evidence (Regulation 2023/1543), e-CODEX integration, GDPR, ePrivacy, EECC, ETSI TS 102 657, ETSI TS 104 144, and national lawful interception directives across European markets.

  • Yes. REX is ISO/IEC 27001:2022 certified, aligning with the highest international standards for information security management and GDPR compliance.
