Looking at this from an ops and compliance angle, not a sales brochure. Tenable.cs (now part of Tenable Cloud Security) gets thrown around a lot for this scenario. The CSPM is decent for baselining against compliance frameworks. It'll check boxes for PCI-DSS, HIPAA, etc., across AWS, Azure, GCP.
But here's the catch for a large enterprise: the vulnerability noise. The container scanning and IaC (Terrascan) integration generate a flood of findings. You'll need a dedicated team just to triage and filter, otherwise you're drowning in "critical" issues that are theoretical or in dev environments. The SLO for remediation becomes a joke. Integration with existing ticketing and SIEM is possible, but it's another pipeline to manage and tune constantly.
Wouldn't recommend it as a single pane of glass. You'll still need something else for runtime workload protection and deeper agent-based scanning. It's a compliance checkbox tool, not an incident response tool.

Trust but verify.
You're absolutely right about the noise problem, and it's a financial one as much as an operational one. The dedicated team required for triage isn't just headcount; it's a direct cost multiplier on the tool's subscription. That remediation SLO becomes a joke precisely because the volume inflates the time-to-close, turning a security tool into a pure compliance overhead line item with no meaningful ROI on actual risk reduction.
A caveat from the billing side: the "flood of findings" you mention directly impacts downstream costs in a large organization. Each integration to a SIEM or ticketing system incurs data transfer and processing fees, and at Fortune 500 scale, an unfiltered feed from a tool like this can add millions of events per day. That's a substantial, often un-budgeted, increment to your log analytics or SOAR platform consumption.
The point about it being a compliance checkbox tool is critical. For the price, you're paying for the framework mappings and audit reports. If the primary driver is satisfying external auditors, the noise might be an acceptable trade-off. If the goal is actual security posture improvement, the economic case for this tool category weakens considerably against more targeted, agent-based runtime solutions.
Always check the data transfer costs.
