Quay vs Prowler
A side-by-side editorial comparison of Quay and Prowler — release velocity, themes, recent moves, and the top alternatives to consider.
Quay vs Prowler: at a glance
What is Quay?
Quay patches three supported lines on one afternoon, mostly CVE bumps.
Quay's enterprise lines ship paired monthly security releases. On November 13 three lines moved within minutes: 3.14.10, 3.12.24 and 3.10.28, each bumping PyJWT, cryptography, pillow, oauthlib and other pinned libraries for CVEs, plus a fix for an onboarding issue. The mirror-registry installer tagged v3.0.0 on November 9 with only dependency bumps noted.
What is Prowler?
Prowler 5.49 asks a new question after each scan: which of your servers run an image under attack?
Prowler ships a minor release every one to two weeks. 5.48 added Realtime for AWS, which checks resources as CloudTrail events arrive and can alert, open a Terraform pull request or fix the resource. 5.49 adds emerging threat signatures: a vulnerability described as data, matched against the machine images of every compute instance on AWS, Azure and Google Cloud, with Amazon Inspector clearing hosts patched in place. Prowler Cloud supplies a threat catalog and turns each threat into an Exploitability issue per account.
Quay vs Prowler: editorial side-by-side
Quay
5.0INFRA · APIS
Quay patches three supported lines on one afternoon, mostly CVE bumps.
◆ Current state
Quay's enterprise lines ship paired monthly security releases. On November 13 three lines moved within minutes: 3.14.10, 3.12.24 and 3.10.28, each bumping PyJWT, cryptography, pillow, oauthlib and other pinned libraries for CVEs, plus a fix for an onboarding issue. The mirror-registry installer tagged v3.0.0 on November 9 with only dependency bumps noted.
◆ Where it's heading
Quay's public changelog is now maintenance only: CVE pins backported to every supported line and build files aligned for Red Hat's ART pipeline. No user-facing features have shipped on these lines in recent months.
◆ Prediction
Expect the next set of paired CVE releases around mid-December; nothing in the entries points to a feature release.
Prowler
7.5INFRA · APIS
Prowler 5.49 asks a new question after each scan: which of your servers run an image under attack?
◆ Current state
Prowler ships a minor release every one to two weeks. 5.48 added Realtime for AWS, which checks resources as CloudTrail events arrive and can alert, open a Terraform pull request or fix the resource. 5.49 adds emerging threat signatures: a vulnerability described as data, matched against the machine images of every compute instance on AWS, Azure and Google Cloud, with Amazon Inspector clearing hosts patched in place. Prowler Cloud supplies a threat catalog and turns each threat into an Exploitability issue per account.
◆ Where it's heading
Prowler is moving from configuration checks toward telling teams what is actually exploitable now: Realtime cut the wait for detection, and threat signatures cut the wait for a new check when a vulnerability lands. The free engine keeps the mechanism, while the maintained catalog and issue triage sit in Prowler Cloud.
◆ Prediction
Expect the threat catalog to grow and exploitability issues to reach more providers or link into Realtime alerts in the next releases.
