What is CrowdSec?

CrowdSec's 1.8.2 candidates let operators write their own bot fingerprints.

The bot detection introduced with 1.8 is now being opened to customization. The 1.8.2 candidates add custom JavaScript fingerprinting, a cscli bot subcommand and a FlagSubmission helper, and rc2 adds a RateLimit helper for the WAF plus a cookie option for embedded contexts. Operational work runs alongside it: a cs_features metric, optional limits on concurrent decision streams and TLS certificate reloads.

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.

CrowdSec's 1.8.2 candidates let operators write their own bot fingerprints.

◆ Current state

The bot detection introduced with 1.8 is now being opened to customization. The 1.8.2 candidates add custom JavaScript fingerprinting, a cscli bot subcommand and a FlagSubmission helper, and rc2 adds a RateLimit helper for the WAF plus a cookie option for embedded contexts. Operational work runs alongside it: a cs_features metric, optional limits on concurrent decision streams and TLS certificate reloads.

◆ Where it's heading

The WAF remains the center of gravity, and the direction is programmability. RateLimit, SkipProcessing and the fingerprinting hooks give rule authors primitives rather than fixed behavior. The LAPI changes point at larger deployments, where decision streaming puts load on the central API.

◆ Prediction

The final 1.8.2 is dated 26 October on GitHub, though it has not reached this feed yet. Whether fingerprint data ever joins the community blocklist remains unanswered in these notes.

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.
