AWS Incident Response Kit (AIRK) is a free digital forensics and incident response tool. Diffy (DEPRECATED) is a free digital forensics and incident response tool. Compare features, ratings, integrations, and community reviews side by side to find the best digital forensics and incident response fit for your security stack.
CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams operating primarily in AWS who need fast containment without waiting for vendors will find AWS Incident Response Kit valuable; it's free, Python-based, and lets you automate isolation of compromised EC2 instances or revoke IAM credentials in seconds rather than minutes. The modular design means you only deploy what you need, and tight AWS API integration eliminates the translation layer other tools introduce. Skip this if your environment is multi-cloud or heavily on-premises, or if your incident response process requires audit-trail compliance beyond what CloudTrail provides; AIRK prioritizes speed over forensic depth.
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.
A Python-based modular incident response tool for AWS environments that enables automated security actions across EC2, IAM, VPC, and other AWS resources.
A deprecated digital forensics tool by Netflix that helped investigators scope compromises across AWS cloud instances by identifying behavioral differences and outliers during security incidents.
