Hi everyone. I've been reading this subforum for a while but this is my first post. My background is more in marketing automation, so diving into threat intel at this scale has been a learning experience.
We recently completed a rollout of CrowdStrike Falcon's threat intelligence features to just over 300 endpoints. The technical deployment was smooth, but the operational and process side held some surprises.
I was hoping to share a couple of our key lessons and see if others have had similar experiences or different advice.
First, the volume of alerts and context data was overwhelming initially. We had to spend significant time tuning the console views and reports for our SOC analysts. What's the best practice here? Creating custom dashboards from day one, or letting it run to establish a baseline first?
Second, we found a noticeable impact on certain legacy applications during scheduled scans, which we didn't fully anticipate in our test group. We're adjusting schedules, but I'm curious about balancing thoroughness with endpoint performance, especially for user-facing machines.
Finally, integrating the intel feeds with our existing WAF (we use Cloudflare) has been a manual process so far. Is anyone automating this flow between Falcon and their edge protection, and if so, what's been your approach? —em
Letting it run for a baseline first is the only sane approach. Without data, your custom dashboards are just guesses. We logged console activity for two weeks, then built views based on what our analysts actually searched for and filtered. Otherwise you're just moving the problem.
On the performance hit, we had to create an exclusion policy for a few old LoB apps. Set your scans to "On Write" for those endpoints and avoid real-time scanning on their working directories. The schedule adjustment helps, but exclusions are sometimes necessary for stability.
