Case Study: Large Energy Supplier achieves automated, zero-touch firewall change management with AlgoSec

Energy supplier keeps the lights on with automated network change management

An international energy supplier that plans, builds and operates the country’s electricity and gas grids—serving millions of customers—ran more than twenty IT and OT firewalls across multiple data centers. They lacked visibility into network topology and traffic flows, relied on Visio and Excel for change management, and had thousands of outdated or redundant rules plus frequent duplicate or unnecessary change requests that slowed operations and increased risk.

They implemented AlgoSec Firewall Analyzer, FireFlow and AlgoBot to map topology and flows, automate policy-change workflows and provide a chatbot interface for stakeholders. The solution centralized visibility, optimized and cleaned up rulebases, provided alerts for expiring rules, enabled zero-touch rule implementation across devices, streamlined audits, met change SLAs and reduced hundreds of monthly change requests to a volume manageable by a single operator.
