What is Dragonfly?

Dragonfly opens a 2.1 line with metrics that explain why replicas drop.

Dragonfly tagged v2.1.0 on November 4, exporting snapshot counters, a save-in-progress gauge and replica disconnects labeled closed, error or timeout. Before, a replica dropped for stalling was indistinguishable from one whose connection simply closed. The 1.40 and 2.0 lines keep getting small cluster-mode fixes, including faster GetSlotInfo and slot migration that no longer drops writes.

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.

Dragonfly vs Prowler: editorial side-by-side

Dragonfly
INFRA · APIS
5.0

Dragonfly opens a 2.1 line with metrics that explain why replicas drop.

◆ Current state

Dragonfly tagged v2.1.0 on November 4, exporting snapshot counters, a save-in-progress gauge and replica disconnects labeled closed, error or timeout. Before, a replica dropped for stalling was indistinguishable from one whose connection simply closed. The 1.40 and 2.0 lines keep getting small cluster-mode fixes, including faster GetSlotInfo and slot migration that no longer drops writes.

◆ Where it's heading

Dragonfly is maturing for production operations: the 2.0 line fixed cluster correctness, and 2.1 starts by making replication and persistence observable from Prometheus. The project says it prefers small incremental features, so 2.1 will likely grow the same way.

◆ Prediction

More metrics and cluster-mode fixes on 2.1, with 1.40 and 2.0 still getting backports for a while.

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.
