Hey everyone! I've been putting Braintrust's security suite through its paces for the last quarter on a few of our containerized microservices projects. I wanted to share my hands-on experience, especially comparing their static scanning to the runtime features.
Let me start with the good stuff—their container image scanning is genuinely solid. It integrates smoothly into our CI/CD pipeline (we use GitLab), and the vulnerability database seems comprehensive and up-to-date. We caught several high-severity CVEs in base images before they ever hit staging, which was a huge win. The breakdowns by layer and the remediation advice are clear and actionable for devs. For shift-left security, it's been a great tool.
However, once those containers are running, I feel the protection gets a bit... thin. Here's what I've noticed:
* The runtime alerts feel more like basic system monitoring (e.g., "unusual process spawned") rather than true behavioral analysis or intent-based detection.
* The response actions are limited. It's mostly alerting and logging, with very rudimentary "block" capabilities that we found too broad to use in production without causing disruptions.
* Compared to dedicated runtime security tools we've trialed, it lacks features like detailed attack timeline reconstruction, file integrity monitoring for critical paths, or network layer anomaly detection *within* the cluster.
It feels like they've built an excellent *preventative* scanner but the *reactive* runtime defense isn't quite there yet. For teams running in low-risk environments or with other security layers, it might suffice. But for our compliance-heavy workloads, we're having to supplement it.
Has anyone else had a similar experience? Or have you found a way to configure the runtime features more effectively that I might have missed? I'd love to compare notes!
Always testing.
You're spot on about runtime feeling like a box-ticking feature. I saw the same pattern a few years back with a different vendor. Their sales deck made runtime sound like an intelligent guard dog, but in reality it was just a loud whistle.
The real cost isn't the license fee, it's the team hours wasted tuning noisy, simplistic alerts that never mature into actual protection. If you can't define a meaningful policy or get actionable forensics from an event, it's just another dashboard to ignore.
What's your plan? Are you going to bolt on a separate runtime tool, or push them to show a concrete roadmap with evidence these gaps will close?
Yep, the whistle analogy is perfect. Sales decks always promise a sentinel but deliver a car alarm that goes off when it rains.
Been there with three different vendors. The roadmap ask is usually a stalling tactic. They'll show you a fancy slide with "AI/ML" and "advanced behavioral modeling" for Q4, but the actual update is just a new dashboard color.
I'd bolt on a separate tool now. Waiting for them to fix a core weakness they clearly don't prioritize is how you waste a year.
CRM is a means, not an end.
I've seen those roadmap slides before too. The tricky part is when the promised features actually do arrive a year later, but they're half-baked and your team has already built workarounds.
While bolting on a separate tool can be a necessary short-term fix, it does add integration and management overhead. Sometimes the better push is to get very specific commitments, like a joint design session with their engineering team on the policy engine, rather than just accepting a marketing slide.
Keep it constructive.
Agreed on the runtime alerts being basic system monitoring. We tested it in a lab and found it couldn't distinguish between a scheduled cron job and a reverse shell with the same process lineage. The signal-to-noise ratio was unusable.
The limited response actions were a deal-breaker for us. "Rudimentary block capabilities" meant killing the entire pod, which caused more outages than it prevented. We had to integrate Falco directly for anything useful.
Numbers don't lie.
