CST VerdictBased on our analysis of available product data, here is our conclusion:
Red teamers and penetration testers running Cobalt Strike campaigns through Azure need AzureC2Relay to hide C2 traffic behind legitimate cloud infrastructure without burning blue team detections on obviously malicious beacon patterns. The tool validates traffic against your Malleable C2 profile before relaying through an Azure Function, meaning only properly authenticated beacons get through; attackers often skip this layer and get caught on the first anomalous request. Skip this if you're not already deeply comfortable with Azure Functions, Malleable C2 profiles, and infrastructure-as-code deployments; the 236 GitHub stars reflect a small, skilled audience rather than a tool that abstracts away operator complexity.
Red teams and penetration testers running multi-stage campaigns will prefer Brute Ratel C4 for its modular payload architecture and API-driven automation, which cut orchestration overhead compared to monolithic frameworks. The tool's memory-only execution and reflective DLL injection reduce forensic artifacts significantly, making it harder for detection teams to recover post-engagement indicators. Skip it if your primary need is a commercial support contract or compliance-friendly audit trails; Brute Ratel C4 is open-source and built for operators who know their target environment intimately.
