Nebula vs Prowler: at a glance
What is Nebula?
Nebula 1.12 adds optional offloading for throughput after a run of platform fixes.
Nebula is a peer-to-peer mesh VPN with its own certificate authority. Since v1.10.0 added IPv6 and multiple overlay addresses, releases have dealt with the fallout: v1.11.1 fixed an IPv6 firewall bypass, and v1.11.2 in September fixed IPv6 MTU on Windows, local address discovery on Android 11+, and checksums for traffic to a host's own IPv6 address on macOS. v1.12.0 on October 29 added optional UDP and TUN offloading, planned to become the default later, and stricter firewall rule parsing.
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.

Nebula 1.12 adds optional offloading for throughput after a run of platform fixes.
◆ Current state
Nebula is a peer-to-peer mesh VPN with its own certificate authority. Since v1.10.0 added IPv6 and multiple overlay addresses, releases have dealt with the fallout: v1.11.1 fixed an IPv6 firewall bypass, and v1.11.2 in September fixed IPv6 MTU on Windows, local address discovery on Android 11+, and checksums for traffic to a host's own IPv6 address on macOS. v1.12.0 on October 29 added optional UDP and TUN offloading, planned to become the default later, and stricter firewall rule parsing.
◆ Where it's heading
The IPv6 work has moved from security fixes to per-platform correctness, and 1.12 turns to throughput. Offloading starting as opt-in, with a stated plan to make it default, sets up the next release cycle.
◆ Prediction
Expect 1.12.x patches for offloading edge cases, and a later release that turns offloading on by default as announced.
Prowler
6.3INFRA · APIS
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.
