What is Buildkite?
Buildkite splits agent tokens into scoped permissions, so a test runner can't read secrets.
Buildkite has spent November tightening who and what can act inside a CI setup. Agent tokens can now be limited to specific capabilities (running jobs, uploading steps, reading secrets, requesting OIDC tokens) and to specific queues, with missing permissions returning a named 403. That follows self-serve SSO resets, organization-wide OAuth revocation, a read-only MCP scope, and hosted agents on Windows and Linux ARM64.
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.

Buildkite

◆ Current state
Buildkite has spent November tightening who and what can act inside a CI setup. Agent tokens can now be limited to specific capabilities (running jobs, uploading steps, reading secrets, requesting OIDC tokens) and to specific queues, with missing permissions returning a named 403. That follows self-serve SSO resets, organization-wide OAuth revocation, a read-only MCP scope, and hosted agents on Windows and Linux ARM64.
◆ Where it's heading
Two threads run in parallel: least-privilege controls for platform teams, and GitHub Actions parity (hosted runners, runs-on labels, cancel_in_progress) to make switching easier. Most of the security work moves controls that used to need Support or broad tokens into the dashboard and into narrower scopes.
◆ Prediction
Expect more scoping of credentials, likely per-pipeline or per-cluster limits on what jobs and AI agents can touch, alongside further hosted-agent platform coverage.
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.
