What is CrowdSec?

CrowdSec's WAF is growing a bot-detection challenge — log analysis meets active interception.

The feed carries only release candidates, roughly one every two to three months, and the WAF has been the centre of gravity across all of them: OpenAPI schema validation, request body size limits, arbitrary AND/OR mixing in rule conditions, more Coraza transformations exposed, RE2 enabled by default on Linux. The 1.8.0 candidate breaks that pattern by adding challenge-and-fingerprint bot detection, serving an interstitial page and evaluating the result against configured rules. The same candidate adds a dedicated Kubernetes datasource that reads logs from the apiserver directly, and HTTP helpers so parsers and scenarios can query external services. Two earlier candidates in the window are pure refactoring with no user-visible change.

What is Prowler?

Prowler is turning its scanner into an agent that can operate the platform, and charging for it.

Prowler ships roughly weekly, alternating feature minors with patch releases of API, UI and SDK fixes. The dominant thread across the last two months is Lighthouse AI, which went from a chat assistant reading findings (5.33.0) to one that takes actions (5.35.0) to one that reaches every tool family the Prowler MCP server exposes, including users and roles (5.37.0). Around it, the platform side has been filling in security-operations workflow: findings triage with lifecycle states, Jira dispatch for finding groups, and Attack Paths query tracking.

CrowdSec's WAF is growing a bot-detection challenge — log analysis meets active interception.

◆ Current state

The feed carries only release candidates, roughly one every two to three months, and the WAF has been the centre of gravity across all of them: OpenAPI schema validation, request body size limits, arbitrary AND/OR mixing in rule conditions, more Coraza transformations exposed, RE2 enabled by default on Linux. The 1.8.0 candidate breaks that pattern by adding challenge-and-fingerprint bot detection, serving an interstitial page and evaluating the result against configured rules. The same candidate adds a dedicated Kubernetes datasource that reads logs from the apiserver directly, and HTTP helpers so parsers and scenarios can query external services. Two earlier candidates in the window are pure refactoring with no user-visible change.

◆ Where it's heading

CrowdSec started as a log-reading detection engine that handed decisions to external bouncers, and the WAF work has been steadily moving it into the request path. Bot detection completes that move: the product now generates its own signal by interrogating the client rather than only inferring from logs. The Kubernetes datasource and the expression-language HTTP helpers point the same way — fewer intermediaries between CrowdSec and both the telemetry and the enforcement point.

◆ Prediction

Expect the fingerprinting rules to become a shared, community-curated resource in the same way detection scenarios already are, since that is the pattern this project applies to every new signal it collects.

Prowler is turning its scanner into an agent that can operate the platform, and charging for it.

◆ Current state

Prowler ships roughly weekly, alternating feature minors with patch releases of API, UI and SDK fixes. The dominant thread across the last two months is Lighthouse AI, which went from a chat assistant reading findings (5.33.0) to one that takes actions (5.35.0) to one that reaches every tool family the Prowler MCP server exposes, including users and roles (5.37.0). Around it, the platform side has been filling in security-operations workflow: findings triage with lifecycle states, Jira dispatch for finding groups, and Attack Paths query tracking.

◆ Where it's heading

The open-source CLI scanner is becoming the data layer for a paid agentic product. The 5.34.0 renaming made the split explicit — Prowler CLI and Prowler Hub stay open, while Cloud, Private Cloud, Lighthouse AI and MCP are the commercial surface — and every Lighthouse release since carries a subscription-only note. The technical bet is that RBAC is a sufficient safety boundary for an agent: Lighthouse can do whatever the asking user could do, which is what allows it to be handed administrative tools rather than read-only ones.

◆ Prediction

Expect the next Lighthouse releases to push into unattended operation — scheduled or event-triggered agent runs rather than chat-initiated ones — since scan scheduling and alert rules are now inside its reach. Continued patch releases fixing Attack Paths graph behaviour on Neo4j and Neptune suggest that subsystem is still settling.
