European Telecom and Media Operator Scales Managed Security Service with Tufin
Download the case study, and learn how Tufin helped a leading European telecom and media operator consolidate three inherited change processes across a 40,000-rule firewall estate — improving change management efficiency by 75% and saving £530,000 annually.
“Post-merger, we were running three different change processes across a 40,000-rule estate. Manual workflows had become the ceiling on every project we delivered, and that ceiling was getting lower every quarter.”
The Challenge: Three Legacy Change Processes Capping Project Delivery
Post-Merger Process Fragmentation: Three different firewall change management workflows inherited from a merger created friction across a 40,000-rule estate and a security culture split across two legacies.
Manual Workflows as a Delivery Ceiling: Roughly 7,500 changes per year ran through manual processes, blocking every project the business tried to deliver and creating room for human error.
Periodic Review, Not Continuous Hygiene: A historical security incident reinforced the need for always-on policy hygiene across the estate, rather than letting drift accumulate between reviews.
The Results: Unified Governance, Faster Delivery, and Major Cost Savings
75% Improvement in Change Management Efficiency: End-to-end automation collapsed multi-week change cycles into days, with every SLA stage running materially faster than the prior manual process.
£530,000 in Annual Operational Savings: Manual effort on rule creation and amendments dropped from ~1,700 people days per year to 630, freeing capacity for higher-value security work.
40,000 Rules Under Continuous Governance: Stale and overly permissive rules now identified and remediated systematically, keeping the estate audit-ready while aligning security and networking teams on a single shared view of policy.
