What is SigNoz?
SigNoz moves log bodies to queryable JSON storage, at a disk cost during migration.
SigNoz now renders AI traces as a conversation in its Thread view, reading OTel gen_ai attributes and SDK-specific formats. The latest release starts moving log bodies to native JSON storage (body_v2), so any field in a log body can be queried by path with less data scanned. During the transition each log body is written twice, so OSS users need extra disk. The v1 alert rule API is still removed on November 11.
What is Prowler?
Prowler 5.49 asks a new question after each scan: which of your servers run an image under attack?
Prowler ships a minor release every one to two weeks. 5.48 added Realtime for AWS, which checks resources as CloudTrail events arrive and can alert, open a Terraform pull request or fix the resource. 5.49 adds emerging threat signatures: a vulnerability described as data, matched against the machine images of every compute instance on AWS, Azure and Google Cloud, with Amazon Inspector clearing hosts patched in place. Prowler Cloud supplies a threat catalog and turns each threat into an Exploitability issue per account.

SigNoz
5.0INFRA · APIS
SigNoz moves log bodies to queryable JSON storage, at a disk cost during migration.
◆ Current state
SigNoz now renders AI traces as a conversation in its Thread view, reading OTel gen_ai attributes and SDK-specific formats. The latest release starts moving log bodies to native JSON storage (body_v2), so any field in a log body can be queried by path with less data scanned. During the transition each log body is written twice, so OSS users need extra disk. The v1 alert rule API is still removed on November 11.
◆ Where it's heading
Alongside the LLM-observability work, SigNoz is rebuilding core storage and APIs: alerting moved to v2alpha1 schemas and logs to structured JSON. The cost is a run of migration notices that OSS and API users must act on.
◆ Prediction
Expect the double-write phase to end in a later release that makes body_v2 the default, and the v1 rules removal to ship on schedule.
Prowler
7.5INFRA · APIS
Prowler 5.49 asks a new question after each scan: which of your servers run an image under attack?
◆ Current state
Prowler ships a minor release every one to two weeks. 5.48 added Realtime for AWS, which checks resources as CloudTrail events arrive and can alert, open a Terraform pull request or fix the resource. 5.49 adds emerging threat signatures: a vulnerability described as data, matched against the machine images of every compute instance on AWS, Azure and Google Cloud, with Amazon Inspector clearing hosts patched in place. Prowler Cloud supplies a threat catalog and turns each threat into an Exploitability issue per account.
◆ Where it's heading
Prowler is moving from configuration checks toward telling teams what is actually exploitable now: Realtime cut the wait for detection, and threat signatures cut the wait for a new check when a vulnerability lands. The free engine keeps the mechanism, while the maintained catalog and issue triage sit in Prowler Cloud.
◆ Prediction
Expect the threat catalog to grow and exploitability issues to reach more providers or link into Realtime alerts in the next releases.
