Prowler vs Umbrel: at a glance
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.
What is Umbrel?
umbrelOS 2.1 beta edits Office files in Files and adds Android and Windows apps.
umbrelOS 2.0 went final on September 22 with Photos, iPhone and Mac apps, Machines, multiple users, an MCP server and FailSafe RAID, and 2.0.1 patched a kernel network CVE on November 1. Three days later the 2.1 Beta 1 opened the next line: a Files viewer that opens and edits PDFs, Word, PowerPoint and Excel files, Umbrel apps for Android and Windows, and bridged networking, USB devices and a shared clipboard for Machines. umbrelOS now also fits phones and tablets.

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.

5.0INFRA · APIS
umbrelOS 2.1 beta edits Office files in Files and adds Android and Windows apps.
◆ Current state
umbrelOS 2.0 went final on September 22 with Photos, iPhone and Mac apps, Machines, multiple users, an MCP server and FailSafe RAID, and 2.0.1 patched a kernel network CVE on November 1. Three days later the 2.1 Beta 1 opened the next line: a Files viewer that opens and edits PDFs, Word, PowerPoint and Excel files, Umbrel apps for Android and Windows, and bridged networking, USB devices and a shared clipboard for Machines. umbrelOS now also fits phones and tablets.
◆ Where it's heading
Each release moves Umbrel further from a box that runs self-hosted apps toward a personal cloud that replaces everyday services: photo backup, file access from every desktop OS, document editing, and virtual machines that behave like real computers on the home network. The companion apps now cover iPhone, Mac, Android and Windows.
◆ Prediction
The 2.1 line will likely take one or two more betas before a stable release, following the 2.0 pattern of two betas then a final. Raspberry Pi devices still lack a patched kernel for the 2.0.1 CVE, so a follow-up fix for them is also likely.
