Agentless coverage and time to value
Weight 18%
Defender: Agentless VM, secrets and Kubernetes scanning exist, but only in the paid Defender CSPM and Defender for Servers Plan 2 tiers.
Sysdig: Agentless posture covers vulnerabilities, misconfigurations, permissions and threats; workload depth needs the agent.
Runtime protection depth
Weight 16%
Defender: Server runtime protection comes through Defender for Endpoint EDR across Azure, AWS, GCP and on-premises machines.
Sysdig: Runtime detection built on Falco, the CNCF graduated project Sysdig created.
Risk prioritization and attack paths
Weight 18%
Defender: Attack path analysis, cloud security explorer and internet exposure analysis sit in Defender CSPM.
Sysdig: Runtime insight into which packages are in use filters out vulnerabilities in code that never runs.
Code-to-cloud and AppSec
Weight 14%
Defender: Code-to-cloud mapping and agentless code-to-cloud container assessment are included in Defender CSPM.
Sysdig: Vulnerability management covers images and workloads; source-code scanning is not a stated focus on the pages we reviewed.
AI workload security
Weight 12%
Defender: AI-SPM in Defender CSPM plus Defender for AI Services, billed per 1,000 tokens.
Sysdig: Sysdig Sage, a GenAI assistant, speeds triage; AI workload posture is less developed on the pages we reviewed.
Ecosystem and integrations
Weight 12%
Defender: Native to Azure and Microsoft's security stack, with AWS and GCP resources covered and billed alongside Azure.
Sysdig: Falco's open-source community and Kubernetes-native tooling extend its reach.
Pricing transparency
Weight 10%
Defender: Foundational CSPM is free, paid plans bill per resource with a public cost calculator, and there is a 30-day free trial.
Sysdig: The licensing unit is published (number of hosts), but prices are by quote.
Scores are 0 to 5. The marker leans toward the stronger vendor; a gap of 1.5 or more pins it to the end. How to read these bars
