CST VerdictBased on our analysis of available product data, here is our conclusion:
Teams running mission-critical applications on AWS who need sub-hour recovery times without buying dedicated disaster recovery infrastructure should start here; AWS Elastic Disaster Recovery eliminates the capital expense of standby hardware by recovering directly into AWS at scale, and the free tier lets you test failover before committing. The service handles continuous replication of on-premises and cloud servers, so your RTO is limited by your network throughput, not your backup window. Skip this if your applications live outside AWS or if you need orchestrated failover across multiple cloud regions; Elastic Disaster Recovery is AWS-centric by design.
Cobalt Strike's ExternalC2 framework
Red team operators and penetration testers who need to test defenses against custom C2 channels will use ExternalC2 to bypass network detection by routing Cobalt Strike traffic through external redirectors and custom protocols. The framework is free and lets you replace Cobalt Strike's default HTTP/HTTPS beaconing entirely, which means your C2 can blend into legitimate traffic patterns your client's sensors won't flag. Skip this if your team runs assessments using only default Cobalt Strike profiles or lacks the network infrastructure to host and manage external redirectors; the setup friction and operational complexity only pay off when you're specifically validating detection gaps around custom C2 communications.
