Just finished my third audit of Lacework this quarter. Every single time, the same bizarre thing happens: duplicate alerts.
We'll get a critical finding for an S3 bucket. Great. Then, five minutes later, the same critical finding, but now it's flagged from the "Cloud Compliance" module instead of "Threat Detection." Same resource, same rule, same everything. Just a different "source" in the platform.
It's like being billed twice for the same meal because the waiter and the chef both told the kitchen. Feels like an artificial way to inflate "insights" or activity. Makes triage a noisy mess.
Anyone else seeing this, or is my config just cursed? Tried deduplication rules, but they don't seem to catch these cross-service duplicates.
Your stack is too complicated.
You're not cursed, this is a known architectural trade-off they've made. Each module operates as an independent detection pipeline with its own evaluation schedule and result store. The deduplication logic typically only runs *within* a module's result set, not across modules.
We ran into this during a POC and confirmed it with their engineering team. The official stance is that "Threat Detection" and "Cloud Compliance" are distinct product lines serving different stakeholder needs, so a finding from both is considered valuable context. I find that justification falls apart during actual incident response.
Your config can't fix it because it's not a config problem. You have to post-process the alert stream externally, grouping by resource ID, rule ID, and timestamp within a tolerance window. We built a small Lambda that consumes the webhook payloads and does this aggregation before forwarding to our SIEM. The noise reduction was about 40% for our environment.
Show me the numbers, not the roadmap.
Welcome to Lacework. Their platform is basically a collection of point solutions glued together, and you're paying for the seams.
That's not a config issue, that's how they built it. The modules don't talk to each other. Makes their dashboard look busy, makes your life harder.
You either build an external aggregator or learn to ignore half the alerts. I chose the latter.
CRM is a necessary evil
Your config isn't cursed, it's just hitting a design flaw. You can't deduplicate across independent pipelines inside their system.
You need an external aggregator. Set up a simple process that consumes the webhook stream, groups events by resource ID, rule ID, and a time window (5 minutes in your case), then forwards only the unique ones to your ticketing system.
Don't try to fix it inside Lacework. Fix it after the fact in your own alert routing.
