What is Prowler?

Prowler 5.46 groups scan findings into issues and extends AI checks to Bedrock and Vertex.

Prowler ships a minor release every one to two weeks. 5.46.0 adds an Issues page to Prowler Cloud that groups a scan's findings into issues with a verdict, new AWS Bedrock, Cognito and WAFv2 checks, a five-check Vertex AI Workbench service on GCP, and checks for PHP runtimes left exposed by the PHP2Shell CVEs across AWS, GCP and Azure. Google Workspace checks now account for the tenant's edition and read the policy Google actually applies.

What is SigNoz?

SigNoz makes LLM traces readable with a conversation-style Thread view.

SigNoz now renders AI traces as a conversation: each LLM call's input and output messages, reasoning, tool calls and results laid out in sequence, instead of raw JSON in span details. It reads OTel gen_ai attributes plus formats from OpenAI, Anthropic, Gemini, LangChain, Vercel AI SDK, LiteLLM, OpenInference and others. The v1 alert rule API is still set for removal on November 11.

Prowler 5.46 groups scan findings into issues and extends AI checks to Bedrock and Vertex.

◆ Current state

Prowler ships a minor release every one to two weeks. 5.46.0 adds an Issues page to Prowler Cloud that groups a scan's findings into issues with a verdict, new AWS Bedrock, Cognito and WAFv2 checks, a five-check Vertex AI Workbench service on GCP, and checks for PHP runtimes left exposed by the PHP2Shell CVEs across AWS, GCP and Azure. Google Workspace checks now account for the tenant's edition and read the policy Google actually applies.

◆ Where it's heading

The open-source engine keeps absorbing coverage where risk is moving: hosted AI services first on Azure in 5.45, now on AWS and GCP, plus fast responses to named CVEs. The paid cloud product keeps adding triage layers on top, from AI fixes per finding to issue grouping, making the free CLI the data source and Prowler Cloud the place findings get worked.

◆ Prediction

Expect AI-service coverage to keep widening across providers and further Prowler Cloud triage features built on the new issue grouping.

5.0

SigNoz makes LLM traces readable with a conversation-style Thread view.

◆ Current state

SigNoz now renders AI traces as a conversation: each LLM call's input and output messages, reasoning, tool calls and results laid out in sequence, instead of raw JSON in span details. It reads OTel gen_ai attributes plus formats from OpenAI, Anthropic, Gemini, LangChain, Vercel AI SDK, LiteLLM, OpenInference and others. The v1 alert rule API is still set for removal on November 11.

◆ Where it's heading

SigNoz is moving into LLM observability from both sides: August's plugin put it inside AI coding agents, and the Thread view now makes it a place to debug AI apps. Underneath, the alerting API keeps migrating on fixed, repeatedly announced dates. Alert channels into incident tools fill out the operational side.

◆ Prediction

Expect more AI-specific views on top of the Thread view, such as token or cost breakdowns per conversation, and the v1 rules removal to ship on November 11 as announced.
