Hey everyone, trying to learn the cloud security side of things. My team was using Lacework for container and cloud security, but we recently switched to Sysdig. The main reason was runtime security for our Kubernetes clusters. Lacework's dashboards were great for compliance, but we felt blind during incidents.
With Sysdig, I'm digging the Falco rules for real-time alerts. Setting up a custom rule for suspicious process execution was straightforward:
```yaml
- rule: Launch Suspicious Network Tool in Container
desc: Detect network tools launched in container
condition: >
container_started and proc.name in (netcat, ncat, nc, tcpdump)
output: >
A network tool was spawned in a container (user=%user.name
command=%proc.cmdline container=%container.info)
priority: WARNING
```
Anyone else made a similar switch? Curious about your take on cost vs. features, especially for container image scanning and CSPM. I'm still new to this, so any insights are appreciated! 😊
I'm a cloud architect at a mid-sized fintech, and we handle about 500 containerized services across a dozen EKS and AKS clusters, so I've spent a lot of time in both platforms.
Here's my breakdown from running Lacework for a year and then switching to Sysdig last quarter:
* **Cost Structure**: Lacework felt like a flat monthly tax on our cloud spend. Sysdig charges per node and per container image scan, which ended up being about 15% cheaper for our mix. The real cost for Sysdig is in data retention; if you want full Falco event history beyond a week, the bill jumps quickly.
* **Deployment Effort**: Lacework's agent was a one-line DaemonSet install and pretty much vanished. Sysdig's agent is heavier and you need to tune Falco rules from day one, which took us a solid two days to quiet the noise. It's more work to get started.
* **Image Scanning Depth**: Lacework's vulnerability database was better for base OS layers and gave clearer fix paths. Sysdig's scanning is faster and integrates tighter with the pipeline, but we've seen more false positives on application libraries.
* **Runtime vs. Compliance Focus**: Lacework wins on cloud compliance (CSPM) and generating audit reports. You click a button and get a PDF for the auditor. Sysdig's runtime security is the differentiator; the ability to trace a process alert directly to a system call and see the full process tree is what you're paying for.
I'd recommend Sysdig specifically if your primary pain is investigating runtime incidents in containers. If your main driver is passing compliance audits and getting a broad cloud security posture report, Lacework is less operational overhead. To make the call clean, tell us what your security team spends more time on: fighting alerts or preparing for audits?

That's a great example of why the Falco engine is so powerful. The ability to write that specific, actionable rule for your own environment is exactly what runtime security should be.
A tip on custom rules: start with very specific conditions like you've done, but log them at INFO or NOTICE priority for a week first. You'd be surprised how many legitimate cron jobs or sidecars use `nc` or `tcpdump`. Bumping it to WARNING after you've verified the noise level will save your team from alert fatigue.
On your question about image scanning and CSPM, that's where the picture gets mixed. Sysdig's image scanning is solid, but their CSPM feels bolted-on compared to Lacework's native strength there. If compliance reporting is a big driver, you might find yourself missing those Lacework dashboards.
