| Dimension | StellaOps Scanner | Trivy |
| --- | --- | --- |
| Architecture & deployment | WebService + Worker services with queue abstraction (Redis Streams/NATS), RustFS/S3 artifact store, PostgreSQL catalog, Authority-issued DPoP tokens, Surface.* libraries for env/fs/secrets, restart-only analyzer plugins.[1](#sources)[3](#sources)[4](#sources)[5](#sources) | Single Go binary CLI with optional server that centralises vulnerability DB updates; client/server mode streams scan queries while misconfig/secret scanning stays client-side; relies on local cache directories.[8](#sources)[15](#sources) |
| Architecture & deployment | WebService + Worker services with queue abstraction (Valkey Streams/NATS, Redis-compatible), RustFS/S3 artifact store, PostgreSQL catalog, Authority-issued DPoP tokens, Surface.* libraries for env/fs/secrets, restart-only analyzer plugins.[1](#sources)[3](#sources)[4](#sources)[5](#sources) | Single Go binary CLI with optional server that centralises vulnerability DB updates; client/server mode streams scan queries while misconfig/secret scanning stays client-side; relies on local cache directories.[8](#sources)[15](#sources) |
| Scan targets & coverage | Container images & filesystem snapshots; analyser families:<br>• OS: APK, DPKG, RPM with layer fragments.<br>• Languages: Java, Node, Python, Go, .NET, Rust (installed metadata only).<br>• Native: ELF today (PE/Mach-O M2 roadmap).<br>• EntryTrace usage graph for runtime focus.<br>Outputs paired inventory/usage SBOMs plus BOM-index sidecar; no direct repo/VM/K8s scanning.[1](#sources) | Container images, rootfs, local filesystems, git repositories, VM images, Kubernetes clusters, and standalone SBOMs. Language portfolio spans Ruby, Python, PHP, Node.js, .NET, Java, Go, Rust, C/C++, Elixir, Dart, Swift, Julia across pre/post-build contexts. OS coverage includes Alpine, RHEL/Alma/Rocky, Debian/Ubuntu, SUSE, Amazon, Bottlerocket, etc. Secret and misconfiguration scanners run alongside vulnerability analysis.[8](#sources)[9](#sources)[10](#sources)[18](#sources)[19](#sources) |
| Evidence & outputs | CycloneDX (JSON + protobuf) and SPDX 3.0.1 exports, three-way diffs, DSSE-ready report metadata, BOM-index sidecar, deterministic manifests, explain traces for policy consumers.[1](#sources)[2](#sources) | Human-readable, JSON, CycloneDX, SPDX outputs; can both generate SBOMs and rescan existing SBOM artefacts; no built-in DSSE or attestation pipeline documented—signing left to external workflows.[8](#sources)[10](#sources) |
| Attestation & supply chain | DSSE signing via Signer → Attestor → Rekor v2, OpenVEX-first modelling, lattice logic for exploitability, provenance-bound digests, optional Rekor transparency, policy overlays.[1](#sources) | Experimental VEX repository consumption (`--vex repo`) pulling statements from VEX Hub or custom feeds; relies on external OCI registries for DB artefacts, but does not ship an attestation/signing workflow.[11](#sources)[14](#sources) |
| Policy & decisioning | Scanner reports facts; Policy Engine, Concelier, and Excititor consume SBOM + VEX to emit explainable verdicts; WebService streams policy previews and report links with tenant enforcement.[1](#sources)[7](#sources) | Built-in misconfiguration checks (OPA/Rego bundles) and severity filtering, but no integrated policy decisioning layer; consumers interpret results or bridge to Aqua commercial offerings.[8](#sources) |
| Offline & air-gap | Offline kits bundle Surface manifests, SBOM artefacts, secrets vault, and configuration; Surface.Env/Validation enforce deterministic prerequisites before work executes; RustFS supports air-gapped object storage.[3](#sources)[4](#sources)[6](#sources) | Supports offline scans by mirroring OCI-hosted vulnerability/Java/check databases, manual cache seeding, `--offline-scan`, and self-hosting VEX repositories; requires operators to keep mirrors fresh.[12](#sources)[13](#sources)[14](#sources) |
| Caching & performance | Layer CAS caching, Content-addressed Surface manifests, queue leasing with retries/dead-letter, EntryTrace reuse, analyzer restart-only plugins for reproducible hot-swaps.[1](#sources)[4](#sources) | Scan cache backends for filesystem, in-memory, or Redis (experimental); caches vulnerability/Java/misconfig bundles locally; BoltDB backend limits concurrent writers.[12](#sources) |

| Security & tenancy | Authority-scoped OpToks (DPoP/mTLS), tenant-aware storage prefixes, secret providers, validation pipeline preventing misconfiguration, DSSE signing for tamper evidence.[1](#sources)[3](#sources)[5](#sources)[6](#sources) | CLI/server intended for single-tenant use; docs emphasise network hardening but do not describe built-in tenant isolation or authenticated server endpoints—deployments rely on surrounding controls.[8](#sources)[15](#sources) |
| Extensibility & ecosystem | Analyzer plug-ins (restart-time), Surface shared libraries, BuildX SBOM generator, CLI orchestration, integration contracts with Scheduler, Export Center, Policy, Notify.[1](#sources)[2](#sources) | CLI plugin framework (`trivy plugin`), rich ecosystem integrations (GitHub Actions, Kubernetes operator, IDE plugins), community plugin index for custom commands.[8](#sources)[16](#sources) |
| Observability & ops | Structured logs, metrics for queue/cache/validation, policy preview traces, runbooks and offline manifest documentation embedded in module docs.[1](#sources)[4](#sources)[6](#sources) | CLI-/server-level logging; documentation focuses on usage rather than metrics/trace emission—operators layer external tooling as needed.[8](#sources) |
