What is Prowler?

Prowler's assistant decides what to do with findings; the patches keep the scanner honest

Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.

What is rsyslog?

The syslog daemon on every Linux box now collects Kubernetes logs itself

rsyslog's August scheduled-stable snapshot adds imkubernetes, an input module that tails pod and container logs directly, handles CRI and Docker json-file records, merges partial CRI lines, and enriches from the Kubernetes API. It lands alongside a segmented disk-assisted queue engine that becomes the default for new stores, a CloudWatch Logs output module, and generic per-action rate limiting in drop or pace mode.

Prowler's assistant decides what to do with findings; the patches keep the scanner honest

◆ Current state

Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.

◆ Where it's heading

Two tracks run in parallel and rarely overlap. The minor releases push the commercial agentic surface forward — triage skills, page context, the MCP tool set — while the patches defend the parts everyone uses: dependency resolution, container CVEs, and check correctness. That second track matters more than its version numbers suggest, because a security scanner reporting PASS when an API call failed is worse than one that errors. 5.39.1 fixes exactly that in the ECS task-definition checks, and makes the SES public-access check evaluate every identity policy rather than stopping at the first.

◆ Prediction

Expect the next minor to extend Lighthouse skills to groups of findings rather than one at a time, with patch releases continuing to absorb Trivy and base-image CVE churn.

The syslog daemon on every Linux box now collects Kubernetes logs itself

◆ Current state

rsyslog's August scheduled-stable snapshot adds imkubernetes, an input module that tails pod and container logs directly, handles CRI and Docker json-file records, merges partial CRI lines, and enriches from the Kubernetes API. It lands alongside a segmented disk-assisted queue engine that becomes the default for new stores, a CloudWatch Logs output module, and generic per-action rate limiting in drop or pace mode.

◆ Where it's heading

Three consecutive snapshots have pushed rsyslog out of its role as a local relay and toward being a full pipeline component: YAML config and native OpenTelemetry protobuf in April, an Elastic Beats input in June, a Kubernetes-native input now. The queue rewrite and rate limiting point at the same target, since those are the properties an edge collector needs to survive backpressure rather than what a syslog relay needs.

◆ Prediction

Expect the next snapshot to harden imkubernetes against the operational cases the notes already hedge on, particularly ServiceAccount token refresh and API failover, and to push more deployments onto segmented queues by default.
