I'm currently evaluating vulnerability management solutions and have narrowed it down to two finalists: CrowdStrike Falcon Spotlight and Tenable.io. My primary concern is operational efficiency on a network of roughly 2000 endpoints.
I've run proof-of-concept tests for both in a segmented environment, but scaling assumptions can be tricky. I'm particularly interested in the end-to-end scan-to-report time for a full, credentialed scan across all nodes. From my limited testing, Falcon's agent-based approach seemed to gather data continuously, while Tenable's scheduled scanner model had a more defined "scan window."
For those who have direct experience at this scale, could you share your real-world metrics or observations?
My key questions are:
* What is the typical total time to get a complete vulnerability snapshot across a 2000-asset network for each platform?
* How much of a factor is network topography and agent deployment status on the scan performance?
* Does the continuous assessment model of Falcon Spotlight actually translate to faster, actionable reporting compared to a traditional scheduled scan?
I'm trying to weigh the architectural differences against practical timelines. Any data points on configuration nuances that significantly impacted your scan times would be incredibly helpful.
