Hey everyone, new here! Been lurking while we evaluate cloud security tools.
We're a mid-sized SaaS company moving more critical customer data to AWS. My team is looking at Tenable Cloud Security (formerly Tenable.cs). The feature list looks solid on paper, but I'm curious about real production use.
Anyone running it on truly critical workloads? Not just for dev/test scans, but for your core production environment with strict compliance needs (like SOC 2, HIPAA). Does it hold up? Specifically worried about performance impact during full scans and if the findings are actionable enough for our small ops team.
Also, how is the onboarding for a team that's more devops than dedicated security? The demo was smooth, but demos always are 😅
Thanks for any insights!
Hey, welcome out of the lurkerspace!
We rolled out Tenable Cloud Security about a year ago on our main production AWS environment, which handles PCI data. So, right in the thick of it.
On performance during full scans: honestly, we saw zero noticeable impact on the workloads themselves. The scanning happens from the outside looking in, mostly via API calls to AWS, so it's not an agent hammering your instances. Our bigger issue was the sheer volume of findings on the first pass. It can be a firehose.

This was our biggest hang-up. It's fantastic at finding misconfigurations, but the "actionability" really depends on how you tune it. Out of the box, you'll get a ton of informational and low-severity stuff that will drown your team. You absolutely need to spend the first few weeks tweaking policies, suppressing known-noisy rules, and integrating the alerts into your existing ticketing system (we use Slack -> Jira). Once we did that, it became manageable and genuinely useful for our devops-leaning folks. The compliance reporting for SOC 2 was a lifesaver during audit time, though.
Onboarding was pretty straightforward for engineers who are already in the AWS console daily. The concepts translate well. Just make sure someone owns the initial policy tuning, or you'll get buried in alerts and hate it.
The demo is smooth because it's a curated slice of cloud assets.
If you don't have dedicated security, the biggest lift isn't the tool, it's defining your own policies for what's "critical." Tenable will show you 300 findings on an S3 bucket. You need to decide which three actually matter for your SOC 2 audit. The tool doesn't do that for you.
Start by mapping their default rules to your specific compliance framework controls. Skip the rest, or you'll drown in noise.
Beep boop. Show me the data.
