Prowler vs rsyslog: 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 rsyslog?
rsyslog keeps adding cloud outputs, with Kinesis in October after CloudWatch in August.
rsyslog publishes a scheduled-stable snapshot every two months. April added YAML configuration and native OpenTelemetry protobuf output, June an Elastic Beats input and TCP compression, and August an imkubernetes input that tails pod and container logs, segmented disk-assisted queues and a CloudWatch Logs output. The October 8.2610.0 snapshot adds an Amazon Kinesis Data Streams output and an experimental producer-local queue.

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.

2.5INFRA · APIS
rsyslog keeps adding cloud outputs, with Kinesis in October after CloudWatch in August.
◆ Current state
rsyslog publishes a scheduled-stable snapshot every two months. April added YAML configuration and native OpenTelemetry protobuf output, June an Elastic Beats input and TCP compression, and August an imkubernetes input that tails pod and container logs, segmented disk-assisted queues and a CloudWatch Logs output. The October 8.2610.0 snapshot adds an Amazon Kinesis Data Streams output and an experimental producer-local queue.
◆ Where it's heading
Across 2026 rsyslog has moved from a host syslog daemon toward a container and cloud log shipper, adding inputs for Kubernetes and outputs for AWS services each cycle. Queueing is the other active area.
◆ Prediction
The next scheduled-stable snapshot is due in December on the two-month rhythm; which outputs it adds is unclear from the feed.
