# Competitive Landscape (Nov 2025)
|
||
|
||
Source: internal advisory “23-Nov-2025 - Stella Ops vs Competitors”. Supersedes/extends prior competitive notes (none published); treat this as canonical until a newer dated advisory arrives. This summary distils the 15-vendor comparison into actionable positioning notes and links back to the full matrix for sales/PMM.
|
||
|
||
## Stella Ops moats (why we win)
|
||
- **Deterministic replay:** feed+rules snapshotting; graph/SBOM/VEX re-run bit-for-bit with manifest hashes.
|
||
- **Hybrid reachability attestations:** graph-level DSSE always; optional edge-bundle DSSE for runtime/init/contested edges; Rekor-backed with publish caps.
|
||
- **Lattice-based VEX engine:** merges advisories, runtime hits, reachability, waivers with explainable paths.
|
||
- **Crypto sovereignty:** FIPS/eIDAS/GOST/SM/PQC profiles and offline mirrors as first-class knobs.
|
||
- **Proof graph:** DSSE + transparency across SBOM, call-graph, VEX, replay manifests.
|
||
|
||
## Top takeaways (sales-ready)
|
||
1. No competitor offers deterministic replay with frozen feeds; we do.
|
||
2. None sign reachability graphs; we sign graphs and (optionally) edges.
|
||
3. Sovereign crypto profiles (FIPS/eIDAS/GOST/SM/PQC) are unique to Stella Ops.
|
||
4. Lattice VEX + explainable paths is unmatched; others ship boolean VEX or none at all.
|
||
5. Offline/air-gap readiness with mirrored transparency is rare; we ship it by default.
|
||
|
||
## Where others fall short (high level)
|
||
- **No deterministic replay:** none of the 15 provide hash-stable, replayable scans with frozen feeds.
|
||
- **No lattice/VEX merge:** VEX is absent or bolt-on; no trust algebra elsewhere.
|
||
- **Attestation gaps:** most rely on Cosign-only or have no DSSE/Rekor story; none sign reachability graphs.
|
||
- **Offline/sovereign:** weak or SaaS-only; no regional crypto options.

## How to use this doc
|
||
- Sales/PMM: pull talking points and the gap list when building battlecards.
|
||
- Product: map gaps to roadmap; keep replay/lattice/sovereign as primary differentiators.
|
||
- Engineering: ensure new features keep determinism + sovereign crypto front-and-center; link reachability attestations into proof graph.

## Battlecard Appendix (snippet-ready)
|
||
|
||
**One-liners**
|
||
- *Replay or it’s noise:* Only Stella Ops can re-run a scan bit-for-bit from frozen feeds.
|
||
- *Signed reachability, not guesses:* Graph DSSE always; optional edge DSSE for runtime/init edges.
|
||
- *Sovereign-first:* FIPS/eIDAS/GOST/SM/PQC profiles and offline mirrors are first-class toggles.
|
||
- *Trust algebra:* Lattice VEX merges advisories, reachability, runtime, waivers with explainable paths.
|
||
|
||
**Proof points**
|
||
- Deterministic replay manifests; BLAKE3 graph hashes; DSSE + Rekor for graphs (edge bundles optional).
|
||
- Hybrid reachability: graph-level attestations plus capped edge-bundle attestations to avoid Rekor flood.
|
||
- Offline: transparency mirrors + sealed bundles keep verification working air-gapped.
|
||
|
||
**Objection handlers**
|
||
- “We already sign SBOMs.” → Do you sign call-graphs and VEX? Do you replay scans bit-for-bit? We do.
|
||
- “Cosign/Rekor is enough.” → Without deterministic manifests + reachability proofs, you can’t audit why a vuln was reachable.
|
||
- “Our runtime traces show reachability.” → We combine runtime hits with signed static graphs and VEX lattice; evidence is replayable and quarantinable edge-by-edge.
|
||
|
||
**CTA for reps**
|
||
- Demo: show `stella graph verify --graph <hash>` with and without edge-bundle verification.
|
||
- Leave-behind: link `docs/reachability/lead.md` and this appendix.
