I've been evaluating Trend Micro Cloud One – Conformity for our AWS workloads over the last quarter, and we're considering a production rollout. However, I'm finding the real-world cost and operational data somewhat sparse beyond the vendor's case studies.
I'm particularly interested in hearing from teams who have moved beyond the POC stage. My main points of inquiry are around the actual **cost allocation and billing model** in a multi-account AWS environment.
* **Pricing Model Nuances:** The per-account, per-region pricing seems straightforward, but how does it handle transient resources? For example, if we spin up a dev account for 48 hours with 50 resources, then tear it down, are we charged for a full month for that account-region combo, or is there any proration? Our finance team is very particular about this.
* **Cost vs. Native Tools:** We currently use a mix of AWS Config, Security Hub, and in-house scripts. The Conformity rules are compelling, but I'm trying to build a tangible FinOps case. Has anyone done a direct cost/benefit analysis comparing the operational overhead of maintaining native tooling versus the subscription cost of Cloud One? Specifically, which "savings" or "risk-avoidance" findings provided the clearest ROI?
* **Resource Overhead:** The lightweight agent (or API-based scanning) is advertised, but in practice, did you notice any measurable impact on your CloudTrail logging costs or API rate limiting during the initial bulk assessment phase?
I'd appreciate any insights on operational pitfalls, especially around rule customization and the feedback loop for false positives. How granular can you get with cost allocation tags to, for instance, charge back the cost of the service to individual application teams?
