What is Merge?

Merge adds security and infra connectors and a half-price flex tier on its gateway.

Merge ships weekly across Agent Handler, Gateway and Unified. The latest Agent Handler batch adds AWS Redshift, CyberArk Identity, Drata, Elasticsearch, JumpCloud, MyCase, Splunk and Terraform, OAuth 2.0 for eight existing connectors, and a Registered Users tab with CSV export. Gateway adds Baseten decision models on /v1/decisions, a flex tier on Particle that bills at half every rate, and key-pinned projects that let customers tighten data-retention and region settings. Unified's UKG Ready leave-of-absence syncs now run about 30 times faster with 20 times fewer API requests.

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.

5.0

Merge adds security and infra connectors and a half-price flex tier on its gateway.

◆ Current state

Merge ships weekly across Agent Handler, Gateway and Unified. The latest Agent Handler batch adds AWS Redshift, CyberArk Identity, Drata, Elasticsearch, JumpCloud, MyCase, Splunk and Terraform, OAuth 2.0 for eight existing connectors, and a Registered Users tab with CSV export. Gateway adds Baseten decision models on /v1/decisions, a flex tier on Particle that bills at half every rate, and key-pinned projects that let customers tighten data-retention and region settings. Unified's UKG Ready leave-of-absence syncs now run about 30 times faster with 20 times fewer API requests.

◆ Where it's heading

Agent Handler's catalog is moving from sales and productivity apps toward security and infrastructure tools, while Gateway competes on price and on customer controls. Unified gets steady mapping and sync fixes rather than new categories.

◆ Prediction

Expect more security and infrastructure connectors in Agent Handler and further service tiers or pricing options on Gateway, given the flex tier's arrival.

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.
