What is Knock?
Notification infrastructure grows a memory: workflows can now wait on the real world.
Knock sells notification infrastructure — workflows, broadcasts, in-app guides, and multi-channel delivery that product teams wire up instead of building themselves. July was dense and unusually broad: a rebuilt Notion-style template editor, saved views and tags, schema management for how properties surface across the dashboard, passkey login, branch rebasing, and sandbox test runs that skip delay steps. Underneath the polish, two structural additions landed — message events syncing into the data warehouse, and a workflow step that pauses until an event arrives.
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.

Notification infrastructure grows a memory: workflows can now wait on the real world.
◆ Current state
Knock sells notification infrastructure — workflows, broadcasts, in-app guides, and multi-channel delivery that product teams wire up instead of building themselves. July was dense and unusually broad: a rebuilt Notion-style template editor, saved views and tags, schema management for how properties surface across the dashboard, passkey login, branch rebasing, and sandbox test runs that skip delay steps. Underneath the polish, two structural additions landed — message events syncing into the data warehouse, and a workflow step that pauses until an event arrives.
◆ Where it's heading
The developer-workflow half of the product is being treated like a codebase: branches that rebase onto main, tests that run in sandbox without delivering, tags and saved views for navigating a growing workspace. The engine half is moving in a different direction — toward workflows that hold state over time. A wait-for-event step, combined with the Clay data source triggering messaging as rows finish enriching, describes journeys rather than notifications. The analytics work is arriving twice over: raw events into the warehouse for teams with their own stack, and natural-language questions to the Knock agent for teams without one.
◆ Prediction
Wait-for-event is the primitive that makes journey-shaped use cases possible, so expect the next releases to address what it exposes — timeouts, observability into workflows sitting paused, and limits on how long one can wait before it becomes a support problem.
Prowler
6.3INFRA · APIS
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.
