What is Prowler?

Prowler 5.48 stops waiting for the next scan: it watches AWS live and can fix what breaks.

Prowler ships a minor release every one to two weeks. 5.48.0 adds Prowler Realtime for AWS in Prowler Cloud: it reads CloudTrail events as they happen, runs a targeted check on the touched resource and then alerts, opens a Terraform pull request or fixes the resource directly, depending on each account's policy. 5.47 had reduced provider setup to one step and made Issues lead with a verdict and an attack path.

What is Robusta?

Robusta's 0.54.0 alpha returns to features: Prometheus tenants by namespace and Holmes fixes.

After a month of image patching and CI changes, Robusta's 0.54.0-alpha.1 carries product work again. It derives the Prometheus tenant from a namespace label in the UI and alert graphs, adds dnsConfig to the forwarder Helm deployment, stops the Holmes Slack bot check from blocking or dropping Slack messages, and retires the grafana-renderer. It also patches another set of Python dependency CVEs and stops self-hosted stores from fetching a Supabase key from SaaS.

Prowler 5.48 stops waiting for the next scan: it watches AWS live and can fix what breaks.

◆ Current state

Prowler ships a minor release every one to two weeks. 5.48.0 adds Prowler Realtime for AWS in Prowler Cloud: it reads CloudTrail events as they happen, runs a targeted check on the touched resource and then alerts, opens a Terraform pull request or fixes the resource directly, depending on each account's policy. 5.47 had reduced provider setup to one step and made Issues lead with a verdict and an attack path.

◆ Where it's heading

Prowler is moving from a periodic scanner toward a response system: partial re-scans in 5.44, exploitability verdicts in 5.46-5.47, and now event-driven detection with reversible auto-remediation. The paid cloud tier carries most of this, with the open scanner feeding it.

◆ Prediction

Expect Realtime to extend to Azure or GCP event feeds and more checks to gain automatic fixes.

5.0

Robusta's 0.54.0 alpha returns to features: Prometheus tenants by namespace and Holmes fixes.

◆ Current state

After a month of image patching and CI changes, Robusta's 0.54.0-alpha.1 carries product work again. It derives the Prometheus tenant from a namespace label in the UI and alert graphs, adds dnsConfig to the forwarder Helm deployment, stops the Holmes Slack bot check from blocking or dropping Slack messages, and retires the grafana-renderer. It also patches another set of Python dependency CVEs and stops self-hosted stores from fetching a Supabase key from SaaS.

◆ Where it's heading

The release mixes multi-tenant Prometheus support, Holmes AI assistant reliability and fewer SaaS dependencies for self-hosted installs. CVE patching remains a constant in every tag.

◆ Prediction

Further Holmes integration work and multi-tenant monitoring changes are the likeliest next items, alongside the usual CVE bumps.
