Duplicati vs Prowler: at a glance
What is Duplicati?
Duplicati's canary brings back one-click updates and restores disk backups to VHD files.
Duplicati 2.4.1 stable added delta backups for Microsoft 365 and Google Workspace and scheduled restore tests. The 2.4.1.101 canary brings back the automatic updater, now a helper that verifies and installs the signed package for each OS, lets a full disk backup be restored into a raw, VHD or VHDX image, and adds an on/off switch per backup. It also fixes a scheduler that silently used UTC and a case where a vanished USB or network destination was recreated empty.
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.

Duplicati
5.0INFRA · APIS
Duplicati's canary brings back one-click updates and restores disk backups to VHD files.
◆ Current state
Duplicati 2.4.1 stable added delta backups for Microsoft 365 and Google Workspace and scheduled restore tests. The 2.4.1.101 canary brings back the automatic updater, now a helper that verifies and installs the signed package for each OS, lets a full disk backup be restored into a raw, VHD or VHDX image, and adds an on/off switch per backup. It also fixes a scheduler that silently used UTC and a case where a vanished USB or network destination was recreated empty.
◆ Where it's heading
The canaries alternate between new restore paths and closing cases where Duplicati looked fine but wasn't, such as silent failures, wrong time zones and missing destinations. The updater makes it easier to keep desktop and server installs on the fixed versions.
◆ Prediction
Expect updater fixes in the next canaries, given that this is its first version, and the disk-image and scheduler work to move into the next stable.
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.
