Semgrep vs Prowler
A side-by-side editorial comparison of Semgrep and Prowler — release velocity, themes, recent moves, and the top alternatives to consider.
Semgrep vs Prowler: at a glance
What is Semgrep?
Semgrep 1.185 drops the SSH server from its Docker image and sharpens PHP call resolution.
Semgrep keeps a weekly cadence on two tracks, matcher depth and Supply Chain. 1.185 resolves virtual calls through basic PHP trait composition, extends range-based requirements.txt findings to the native resolver, adds structured JSON execution logs and secrets-validator telemetry, and removes sshd and sftp-server from the semgrep/semgrep Docker image. A 3% median scan speedup comes from simpler dataflow variable keys.
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.

Semgrep
5.0INFRA · APIS
Semgrep 1.185 drops the SSH server from its Docker image and sharpens PHP call resolution.
◆ Current state
Semgrep keeps a weekly cadence on two tracks, matcher depth and Supply Chain. 1.185 resolves virtual calls through basic PHP trait composition, extends range-based requirements.txt findings to the native resolver, adds structured JSON execution logs and secrets-validator telemetry, and removes sshd and sftp-server from the semgrep/semgrep Docker image. A 3% median scan speedup comes from simpler dataflow variable keys.
◆ Where it's heading
Supply Chain is closing the gaps where unpinned Python requirements used to go unseen, now in both resolvers. Alongside, Semgrep is investing in operability: structured logs, telemetry and a smaller container attack surface suggest more customers run it in their own pipelines and want to audit it.
◆ Prediction
Expect the requirements.txt range logic to spread to other ecosystems with loose version specs, and more structured log events following SEMGREP_LOG_JSON_FILE.
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.
