Oh Dear vs Prowler: at a glance
What is Oh Dear?
Oh Dear adds free public tools after five weeks of security fixes
Oh Dear, an uptime and site monitoring service, publishes a changelog each week. The 6 November entry adds free public tools, a cron expression editor, SSL certificate checker, redirect checker and DNS watch, and fixes confusing wording on passing certificate checks. The weeks before brought custom webhook headers, 30 to 90 days of status page history and AI fix prompts in Broken Links alerts, along with fixes for a high-severity SSRF, a status page CNAME takeover and scoped API token access.
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.

◆ Current state
Oh Dear, an uptime and site monitoring service, publishes a changelog each week. The 6 November entry adds free public tools, a cron expression editor, SSL certificate checker, redirect checker and DNS watch, and fixes confusing wording on passing certificate checks. The weeks before brought custom webhook headers, 30 to 90 days of status page history and AI fix prompts in Broken Links alerts, along with fixes for a high-severity SSRF, a status page CNAME takeover and scoped API token access.
◆ Where it's heading
After a run of security fixes, Oh Dear is adding top-of-funnel tools that let non-customers test one thing for free. Product work is otherwise steady small improvements to notifications and status pages.
◆ Prediction
More free single-purpose tools are likely, along with continued weekly notification and status page polish.

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.
