What is Prowler?
Prowler's agentic defender arrives — and it lives entirely behind the subscription line
Prowler is a cloud security posture platform with an open scanner at its base and a hosted product above it. The recent releases are dominated by Lighthouse AI, which arrived in 5.33.0 as an agentic assistant wired to the Prowler Cloud backend that discovers and runs Prowler's own tools to answer questions about findings, compliance posture and risky resources, then gained a persistent side panel in 5.35.0. Every one of these features carries the same note: available exclusively in Prowler Cloud and Prowler Private Cloud with a subscription. The 5.34.0 release renamed the product family to match that structure.
What is Ably?
Ably is building an agent transport layer, shipping a new AI SDK version roughly every ten days.
The AI Transport JS SDK moved from 0.4.0 to 0.7.0 inside a single month, each release adding a distinct piece of agent infrastructure: seeding a conversation from an app's own message store, a Step primitive that survives process restarts under Temporal or Vercel's Workflow Development Kit, mid-run steering through run.steer(), and a codec that streams the OpenAI Responses API over a channel with client-executed tools and human approvals. In parallel, the established Pub/Sub line is spreading LiveObjects further — a path-based API in the Java SDK, a useObject React hook, and React Native push support.

Prowler's agentic defender arrives — and it lives entirely behind the subscription line
◆ Current state
Prowler is a cloud security posture platform with an open scanner at its base and a hosted product above it. The recent releases are dominated by Lighthouse AI, which arrived in 5.33.0 as an agentic assistant wired to the Prowler Cloud backend that discovers and runs Prowler's own tools to answer questions about findings, compliance posture and risky resources, then gained a persistent side panel in 5.35.0. Every one of these features carries the same note: available exclusively in Prowler Cloud and Prowler Private Cloud with a subscription. The 5.34.0 release renamed the product family to match that structure.
◆ Where it's heading
The direction is a platform sorting its value above the scanner. Findings are becoming workflow objects rather than report rows — grouped or separate Jira issues carrying Prowler context and deep links — while the AI layer moves from a page you visit to a panel that follows you through the app. The patch releases underneath tell the other half of the story: Attack Paths graph mutations retrying Neptune concurrency failures, bounded node identifiers to avoid Neo4j index key limits, deterministic upsert ordering to prevent PostgreSQL deadlocks. That is a graph-backed analysis engine being scaled under load while the differentiated surface is built on top.
◆ Prediction
Expect Lighthouse AI to keep absorbing workflow actions — ticketing, remediation suggestions, compliance queries — and for the gap between the open scanner and the subscription platform to keep widening.

Ably is building an agent transport layer, shipping a new AI SDK version roughly every ten days.
◆ Current state
The AI Transport JS SDK moved from 0.4.0 to 0.7.0 inside a single month, each release adding a distinct piece of agent infrastructure: seeding a conversation from an app's own message store, a Step primitive that survives process restarts under Temporal or Vercel's Workflow Development Kit, mid-run steering through run.steer(), and a codec that streams the OpenAI Responses API over a channel with client-executed tools and human approvals. In parallel, the established Pub/Sub line is spreading LiveObjects further — a path-based API in the Java SDK, a useObject React hook, and React Native push support.
◆ Where it's heading
The pattern is a realtime messaging company treating agent runs as the thing its network transports. Each AI Transport release closes a gap that would otherwise force developers to build around the channel — history reconciliation, crash recovery, changing direction mid-response, and now speaking a specific model provider's wire format. The LiveObjects work runs on a slower track and points the same way: path-based subscriptions that survive structural change are aimed at the fast-mutating state agents and collaborative apps produce.
◆ Prediction
Expect the codec pattern to extend to other model provider APIs beyond OpenAI Responses, and the LiveObjects path-based API to keep propagating across the remaining SDK languages after Java.
