Ermetic vs Aqua Security

Aqua Security and Ermetic are both cnapp platform solutions. Aqua Security cloud-native security platform specializing in container, Kubernetes, and serverless protection, while Ermetic cloud identity security platform specializing in CIEM and entitlement management, now part of Tenable. The best choice depends on your organization's size, technical requirements, and budget.

The Verdict

Choose Aqua Security if industry-leading container and Kubernetes security depth is your priority and organizations running container-heavy and Kubernetes-native environments that need the deepest container security and runtime protection. Choose Ermetic if deepest CIEM capabilities with granular identity risk analysis matters most and organizations where cloud identity and access management risk is the primary security concern, especially those already using Tenable products.

When to Choose Each Tool

Choose Aqua Security when:

  • +You value deepest CIEM capabilities with granular identity risk analysis
  • +You value automated least-privilege recommendations reduce manual IAM remediation
  • +You value strong cross-cloud identity correlation across AWS, Azure, and GCP
  • +You want to avoid cSPM capabilities less mature than dedicated CSPM platforms like Wiz
  • +You want to avoid agent-based runtime protection adds deployment and management complexity

Choose Ermetic when:

  • +You value industry-leading container and Kubernetes security depth
  • +You value open-source Trivy scanner is the most widely adopted cloud-native scanner
  • +You value strong runtime protection with drift prevention and behavioral monitoring
  • +You want to avoid narrower platform scope focused primarily on identity and posture
  • +You want to avoid being absorbed into Tenable Cloud Security may cause product direction uncertainty

Pros & Cons Comparison

Aqua Security

Pros

  • +Strong container and Kubernetes security depth
  • +Open-source Trivy scanner is the most widely adopted cloud-native scanner
  • +Strong runtime protection with drift prevention and behavioral monitoring
  • +Excellent DevSecOps integration with CI/CD pipelines
  • +eBPF-based Tracee provides lightweight runtime detection

Cons

  • CSPM capabilities less mature than dedicated CSPM platforms like Wiz
  • Agent-based runtime protection adds deployment and management complexity
  • Platform can feel fragmented between open-source and commercial components
  • Less effective for VM-centric or non-containerized cloud workloads
  • Enterprise pricing can escalate quickly for large container environments

Ermetic

Pros

  • +Deepest CIEM capabilities with granular identity risk analysis
  • +Automated least-privilege recommendations reduce manual IAM remediation
  • +Strong cross-cloud identity correlation across AWS, Azure, and GCP
  • +Now part of Tenable, benefiting from broader vulnerability intelligence
  • +Effective at identifying toxic permission combinations

Cons

  • Narrower platform scope focused primarily on identity and posture
  • Being absorbed into Tenable Cloud Security may cause product direction uncertainty
  • Lacks workload protection and container security depth
  • No runtime detection or response capabilities
  • Smaller standalone market presence following acquisition

Ermetic vs Aqua Security FAQ

Quick answers for teams evaluating Ermetic vs Aqua Security.

What is the main difference between Ermetic and Aqua Security?

Aqua Security and Ermetic are both cnapp platform solutions. Aqua Security cloud-native security platform specializing in container, Kubernetes, and serverless protection, while Ermetic cloud identity security platform specializing in CIEM and entitlement management, now part of Tenable. The best choice depends on your organization's size, technical requirements, and budget.

Is Aqua Security better than Ermetic?

Choose Aqua Security if industry-leading container and Kubernetes security depth is your priority and organizations running container-heavy and Kubernetes-native environments that need the deepest container security and runtime protection. Choose Ermetic if deepest CIEM capabilities with granular identity risk analysis matters most and organizations where cloud identity and access management risk is the primary security concern, especially those already using Tenable products.

How much does Aqua Security cost compared to Ermetic?

Aqua Security starts at Free (Trivy OSS) / Enterprise custom pricing (workload-based (per protected workload)). Ermetic starts at Custom enterprise pricing (via Tenable) (resource-based (per cloud identity)). As always, the sticker price only tells part of the story. Factor in add-ons, implementation costs, and what's actually included at each tier.

Can I migrate from Ermetic to Aqua Security?

It depends on how deeply Ermetic is embedded in your stack. Most teams run both in parallel for a few weeks before cutting over. Check whether Aqua Security supports importing your existing configs or policies. That's usually the biggest time sink.
