What is Tailscale?

Tailscale makes a device's public IP a posture check, after three client security patches.

Tailscale is moving tailnet administration into policy and automation: MagicRoute, declarative node sharing, OAuth device provisioning and posture alerts all landed in October. The 1.104 client line underneath turned into a run of security patches, v1.104.2, v1.104.4 and v1.104.5, in under two weeks. November opened with the public IP address posture attribute going GA and the India relay servers moving from Bengaluru to Mumbai.

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.

Tailscale makes a device's public IP a posture check, after three client security patches.

◆ Current state

Tailscale is moving tailnet administration into policy and automation: MagicRoute, declarative node sharing, OAuth device provisioning and posture alerts all landed in October. The 1.104 client line underneath turned into a run of security patches, v1.104.2, v1.104.4 and v1.104.5, in under two weeks. November opened with the public IP address posture attribute going GA and the India relay servers moving from Bengaluru to Mumbai.

◆ Where it's heading

Device posture keeps gaining inputs: alerts and badges in October, now where a device connects from. Access rules are drifting from who you are toward what the device is and where it sits, all expressed in policy.

◆ Prediction

More posture attributes and posture-driven actions in the admin console look likely, given monitoring, alerts and now public IP shipped within a month.

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.
