Alright, let's get this out there: I'm convinced that half the "critical" security advice these platforms spit out for Terraform is just noise designed to make the dashboard look busy. I've been bounced between Snyk and now Wiz for the last quarter, and the quality of the *actual fix* guidance is wildly different.
Snyk feels like it's been doing this longer, especially on the open-source library side, so its IaC checks often come with a direct link to the relevant OSS policy or CVE. But for Terraform? It'll tell you your S3 bucket is open to the world (great), and the remediation is a generic "apply the following policy." Sometimes it's even outdated for the provider version.
Wiz, with its cloud-native everything focus, seems to scan the actual runtime environment *and* the IaC, which leads to more contextual "this is actually exploitable because..." warnings. The advice feels less academic. But I've caught it suggesting fixes that would break dependencies in other modules—it's a bit myopic.
* **Snyk's strength:** Depth on known vulnerabilities, clearer licensing issues in modules. The fix is usually *correct*, but might be a blunt instrument.
* **Wiz's angle:** Better cloud context ("this Terraform misconfiguration is actively exposed via your VM"). The fix might be more tailored, but I've seen it miss broader code hygiene issues.
So which one actually gives you a fix you can apply without having to double-check it on Stack Overflow? For a team trying to move fast without creating new problems, is the cloud-context worth the occasional blind spot?
