From 28 Days to 48 Hours: Automating Security with GuardOne

Executive Summary

For one of the leading financial institutions in Asia, rapid inorganic growth created a security nightmare. A sprawling, heterogeneous infrastructure resulting from recent regional acquisitions left their lean SecOps team overwhelmed by vulnerability alerts. Their Mean Time to Remediate (MTTR) for critical vulnerabilities was slipping past acceptable industry standards. By deploying NimbusOne’s GuardOne platform and leveraging its integrated automation engine, NetGenie, the organization slashed its critical patch cycle by over 90%, turning a monthly scramble into a daily operational routine.

The Challenge: Inorganic Growth and the “Patch Gap”

The organization is a dominant force in the Asian banking and payment processing space. Following the acquisition of two regional competitors, their infrastructure ballooned overnight to nearly 3,500 assets spread across legacy on-premise data centers, AWS, and Azure instances.

Their existing vulnerability scanning tool was adept at finding problems, but terrible at helping fix them.

“We were running weekly scans and getting reports with over 18,000 total detected vulnerabilities across the new expanded environment,” explained the institution’s Chief Information Security Officer (CISO). “Even after filtering for just ‘Critical’ and ‘High’ severity CVSS scores, we were looking at a backlog of roughly 1,200 active risks at any given moment.”

The real issue, however, was the remediation gap. The process was highly manual:

  1. Security analysts dumped data into massive spreadsheets.
  2. They manually tried to determine which assets were internet-facing or holding sensitive financial data.
  3. Tickets were cut to IT Operations for patching.
  4. IT Ops struggled with different patching tools for Linux, Windows, and third-party applications.

 

The result? The institution’s MTTR for critical vulnerabilities hovered around 28 days—a dangerous window of exposure in the heavily targeted financial sector.

The Solution: GuardOne and the Power of NetGenie

Realizing that throwing more bodies at the problem wasn’t scalable, the organization turned to GuardOne for its integrated approach to the Vulnerability Management Lifecycle.

GuardOne immediately addressed the two primary bottlenecks: Prioritization and Execution.
