Case Study: Telefónica Mexico achieves 50% faster firewall change deployment and improved network security with AlgoSec

Telefonica Mexico Improves Networks Security with Algosec

Telefónica Mexico, a major telecom provider serving over 20 million customers, faced scaling challenges as network growth multiplied the number of firewalls protecting services. A three-person security team was manually handling roughly 30 firewall changes per day with limited visibility into rules and relationships, making risk mitigation and change management error-prone and inefficient.

After evaluating options, Telefónica deployed the AlgoSec Security Management Solution for its automated risk analysis, reporting and local support; it was up and running in a week. AlgoSec halved the time required for firewall change management, improved change accuracy and network security through visual risk displays and “what‑if” testing, detected unauthorized modifications, and produced automated SOX compliance reports—allowing Telefónica to manage growth without adding staff.
