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 Robusta?

Robusta's recent releases patch its runner image rather than add features.

Robusta ships from an alpha channel, so alpha tags are its release line. The October tags are almost entirely image and CI work: 0.52.0-alpha patched high and critical CVEs in the runner image and removed orphaned Perl packages after a Debian upgrade, 0.52.0-alpha.1 backported OpenSSH, curl, expat and systemd fixes from Debian forky, and 0.54.0-alpha's notes cover only the removal of helm golden-file tests from CI. The last feature work in the feed was August's workflow trigger action and the signing-key leak fix.

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.

Robusta's recent releases patch its runner image rather than add features.

◆ Current state

Robusta ships from an alpha channel, so alpha tags are its release line. The October tags are almost entirely image and CI work: 0.52.0-alpha patched high and critical CVEs in the runner image and removed orphaned Perl packages after a Debian upgrade, 0.52.0-alpha.1 backported OpenSSH, curl, expat and systemd fixes from Debian forky, and 0.54.0-alpha's notes cover only the removal of helm golden-file tests from CI. The last feature work in the feed was August's workflow trigger action and the signing-key leak fix.

◆ Where it's heading

Since late August the project has been treating its container image as the product surface that needs attention, with CVE patching handled by backporting packages from the next Debian release. The feature line that added workflow chaining, JSON logs and new alert sources has gone quiet in these entries. The 0.53 tag does not appear in the feed, so part of the picture may be missing.

◆ Prediction

Expect more runner-image CVE releases on the alpha line. Whether feature work on Holmes integration or alert sources resumes is not visible in these entries.
