CST VerdictBased on our analysis of available product data, here is our conclusion:
AWS incident responders investigating active compromises across multiple EC2 instances should know about Diffy; it surfaces behavioral anomalies and file differences that manual comparison misses, collapsing hours of forensic work into minutes. Netflix open-sourced the tool with 631 GitHub stars and zero licensing friction, meaning you can deploy it immediately without vendor negotiations. Stop here if your incidents span on-premises systems or non-AWS cloud providers, since Diffy was purpose-built for AWS instance forensics and lacks the portability you'd need.
