CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Enterprise and mid-market teams protecting sensitive workloads from insider threats and memory-based attacks will find Anjuna Seaglass valuable because it encrypts data in-use via hardware enclaves, not just at rest or in transit. The no-code wrapping approach means you can move existing containerized apps into Confidential Containers without rewriting application code, and multi-cloud deployment across AWS, Azure, and GCP reduces vendor lock-in. This is not for teams whose primary concern is preventing initial compromise or lateral movement; Seaglass assumes the container already runs and focuses on what happens inside it, leaving your CNAPP and network detection work largely unchanged.
Hardware security teams protecting ARM-based IoT and embedded devices will get the most from ARM TrustZone because it isolates sensitive workloads at the processor level, where software-only defenses can't reach. The free pricing and 977 GitHub stars reflect genuine adoption in resource-constrained environments where traditional EDR is impractical. Skip this if you're looking for visibility into user behavior or threat hunting; TrustZone is a containment mechanism, not a detection platform, and it requires integrating your apps into its secure execution environment during development.
