Thanks to Illumio Core’s real-time application dependency map, Hanna gained complete visibility into Hi-Temp’s east-west internal network traffic flows and application chatter. Now he could quickly identify risky traffic pathways and shut down unnecessary connections. The Illumio application dependency map also helps inform Hi-Temp’s segmentation policy decisions.
Illumio Core’s orchestration of the Windows Filtering Platform at the server level to enforce policies removes the burden of network changes or disruptions. Hanna built and monitored policies in test mode to vet the potential impact before moving to enforcement. He ultimately reduced the number of rules from hundreds in Windows Group Policy to only 19 Illumio policies. In addition, Hanna can now deploy changes in minutes, down from hours using GPOs.
Long gone are the days of trawling through logs and firewall alerts, Hanna says. Using the Explorer capability in Illumio Core, Hi-Temp has gained a historical view of all traffic flows, speeding both troubleshooting and incident response.
“Explorer provides significant time savings and operational efficiencies, allowing me to cover more ground in a day,” Hanna says. “It’s as simple as quickly punching in a query to look up traffic and being able to rectify issues in minutes.”
