Cloud Application Detection and Response (CADR)
Also known as: Application Detection and Response (ADR)
What is CADR/ADR?
Cloud Application Detection and Response (CADR), sometimes called Application Detection and Response (ADR), is a new and emerging category of cloud security solutions. Unlike traditional CNAPP, CASB, or CDR tools, CADR/ADR focuses on deep, runtime detection and response at the application layer within cloud environments. This category is primarily driven by startups and is rapidly evolving.
What problem does it target?
- Detects and responds to attacks at the application layer in cloud-native environments (SaaS, PaaS, IaaS)
- Provides visibility and actionable context for application-layer exploits, lateral movement, and multi-stage attacks
- Addresses gaps left by CNAPP, CDR, and CASB, which often lack deep application runtime visibility
How does it work?
CADR/ADR solutions typically:
- Monitor application behavior and data flows in real time
- Correlate events across application, workload, and cloud layers
- Use advanced analytics and behavioral modeling to detect suspicious or malicious activity
- Provide automated or guided response actions (block, restrict, alert)
- Integrate with SIEM, SOAR, and other security operations tools
Key Features
- Deep runtime visibility into application-layer activity
- Detection of sophisticated, multi-stage attacks spanning application and cloud
- Automated and manual response capabilities
- Reporting and analytics for incident investigation and security improvement
- Support for regulatory compliance by monitoring data movement and application behavior
Market Landscape
- This is a new and rapidly evolving category, with most activity from startups
- Sometimes referred to as Application Detection and Response (ADR)
- Key emerging vendors: ARMO, Sweet, Upwind, Oligo, Operant, Raven
Implementation Considerations
- Requires continuous monitoring and regular policy updates
- User and developer education is critical to address evolving threats
- Best results when integrated with broader security operations (SIEM, SOAR, etc.)
