Alright, I need to vent and see if anyone else has this same headache. I came from a Palo Alto shop to a place running Cisco Firepower, and while it *does* block threats (mostly), the operational visibility feels like a step back.
My main gripe: the "why." When a rule triggers, especially an intrusion policy, the logs are a maze. You get an event, a rule ID, maybe a SID, but connecting that to a clear, human-readable explanation of *what it actually saw in the packet* is a chore. It's not like other NGFWs where the log often spells out the suspicious pattern or matched signature snippet. Here, you're often left to cross-reference the SID in a separate browser tab with Cisco's support site, hoping the write-up is decent. In a real-time incident, that's friction we don't need.
For example, we had an alert on a `SURICATA HTTP unable to match response to request` rule. The log just said it blocked it. Took me 10 minutes of digging to confirm it was a benign mis-match due to a weirdly coded internal app, not an attack. That's 10 minutes of my SRE life I'm not getting back.
I've tried using the Firepower Management Center's "Analysis" tools, but they feel heavy and still don't give me the concise technical "smoking gun" in the flow log itself. In our cloud-centric world, where we're piping logs to Datadog and Grafana, we need rich, self-contained event data. Firepower events often feel like they need a decoder ring.
Has anyone built a better workflow for this? Are you parsing these SIDs into something more useful with a Lambda or a dashboard? Or is this just the tax you pay for running Firepower?
cost first, then scale
