Fission vs Prowler: at a glance
What is Fission?
Fission's release feed carries only RC tags, and none of them say what shipped
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.
What is Prowler?
Prowler 5.48 stops waiting for the next scan: it watches AWS live and can fix what breaks.
Prowler ships a minor release every one to two weeks. 5.48.0 adds Prowler Realtime for AWS in Prowler Cloud: it reads CloudTrail events as they happen, runs a targeted check on the touched resource and then alerts, opens a Terraform pull request or fixes the resource directly, depending on each account's policy. 5.47 had reduced provider setup to one step and made Issues lead with a verdict and an attack path.

◆ Current state
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.
◆ Where it's heading
What can be read from these tags is infrastructure maintenance rather than product direction: Go dependency updates, helm and kind and skaffold and cosign version refreshes, and regenerated swagger and applyconfiguration files kept in sync with CEL and webhook validation comments in the core API types. That last one is the only entry hinting at anything structural — CEL-based validation on the API types implies declarative validation moving into the CRDs — but the commit itself changes only generated output.
◆ Prediction
This feed does not carry enough to predict product direction; until final releases or their notes appear here rather than only candidate tags, any read of where Fission is heading would be guesswork.
Prowler
6.3INFRA · APIS
Prowler 5.48 stops waiting for the next scan: it watches AWS live and can fix what breaks.
◆ Current state
Prowler ships a minor release every one to two weeks. 5.48.0 adds Prowler Realtime for AWS in Prowler Cloud: it reads CloudTrail events as they happen, runs a targeted check on the touched resource and then alerts, opens a Terraform pull request or fixes the resource directly, depending on each account's policy. 5.47 had reduced provider setup to one step and made Issues lead with a verdict and an attack path.
◆ Where it's heading
Prowler is moving from a periodic scanner toward a response system: partial re-scans in 5.44, exploitability verdicts in 5.46-5.47, and now event-driven detection with reversible auto-remediation. The paid cloud tier carries most of this, with the open scanner feeding it.
◆ Prediction
Expect Realtime to extend to Azure or GCP event feeds and more checks to gain automatic fixes.
