Case Study: T‑Mobile achieves streamlined change management and PCI compliance with AlgoSec

T-Mobile Optimize Change Management and Ensures Algosec with Compliance

T‑Mobile UK, a leading mobile operator serving millions of customers, faced a complex network environment with scores of internal firewalls and many outsourced components that all needed to meet strict internal standards and PCI‑DSS compliance. The company struggled to understand risk in legacy firewall rulesets and to track and control changes, creating audit and change‑management challenges.

T‑Mobile selected AlgoSec’s Security Management solution for its partner approach and strong technical fit; a six‑month project analyzed and documented all firewall rulesets and put them into maintenance. AlgoSec’s change‑automation gave assurance that signed changes were actually implemented, dramatically reduced audit effort and resources, delivered rapid ROI, and provided clear, impartial proof of outsourcer compliance against T‑Mobile’s policies.
