Competitive Landscape
TL;DR: Stella Ops isn't a scanner that outputs findings. It's a platform that outputs attestable decisions that can be replayed. That difference survives auditors, regulators, and supply-chain propagation.
Source: internal advisory "23-Nov-2025 - Stella Ops vs Competitors", updated Jan 2026. This summary distils a 15-vendor comparison into actionable positioning notes for sales/PMM and engineering prioritization.

| Verification Method |
Source code audit (OSS), documentation review, feature testing |
Confidence Levels:
- High (80-100%): Verified against source code or authoritative documentation
- Medium (50-80%): Based on documentation or limited testing; needs deeper verification
- Low (<50%): Unverified or based on indirect evidence; requires validation
Why Competitors Plateau (Structural Analysis)
The scanner market evolved from three distinct origins. Each origin created architectural assumptions that make Stella Ops' capabilities structurally difficult to retrofit.
| Origin |
Representatives |
What They Optimized For |
Why They Can't Easily Catch Up |
| Package Scanners |
Trivy, Syft/Grype |
Fast CLI, broad ecosystem coverage |
No forensic reproducibility in architecture; VEX is boolean, not lattice; no DSSE for reachability graphs |
| Developer UX |
Snyk |
IDE integration, fix PRs, onboarding |
SaaS-only (offline impossible); no attestation infrastructure; reachability limited to specific languages |
| Policy/Compliance |
Prisma Cloud, Aqua |
Runtime protection, CNAPP breadth |
No deterministic replay; no cryptographic provenance for verdicts; no semantic diff |
| SBOM Operations |
Anchore |
SBOM storage, lifecycle |
No lattice VEX reasoning; no signed reachability graphs; no regional crypto profiles |
The Core Problem
Scanners output findings. Stella Ops outputs decisions.
A finding says "CVE-2024-1234 exists in this package." A decision says "CVE-2024-1234 is reachable via this call path, vendor VEX says not_affected but our runtime disagrees, creating a conflict that policy must resolve, and here's the signed proof chain."
This isn't a feature gap—it's a category difference. Retrofitting it requires:
- Rearchitecting the evidence model (content-addressed, not row-based)
- Adding lattice logic to VEX handling (not just filtering)
- Instrumenting reachability at three layers (static, binary, runtime)
- Building deterministic replay infrastructure (frozen feeds, manifests, seeds)
- Implementing regional crypto profiles (not just "signing")

The Five One-Liners
| # |
One-Liner |
What It Means |
Claim IDs |
| 1 |
"We don't output findings; we output attestable decisions that can be replayed." |
Given identical inputs, Stella produces identical outputs. Any verdict from 6 months ago can be re-verified today with stella replay srm.yaml. |
DET-001, DET-003 |
| 2 |
"We treat VEX as a logical claim system, not a suppression file." |
K4 lattice logic aggregates multiple VEX sources, detects conflicts, and produces explainable dispositions with proof links. |
VEX-001, VEX-002 |
| 3 |
"We provide proof of exploitability in this artifact, not just a badge." |
Three-layer reachability (static graph + binary + runtime) with DSSE-signed call paths. Not "potentially reachable" but "here's the exact path." |
REACH-001, REACH-002 |
| 4 |
"We explain what changed in exploitable surface area, not what changed in CVE count." |
Smart-Diff outputs "This release reduces exploitability by 41% despite +2 CVEs" — semantic risk deltas, not raw numbers. |
— |
| 5 |
"We quantify uncertainty and gate on it." |
Unknowns are first-class state with bands (HOT/WARM/COLD), decay algorithms, and policy budgets. Uncertainty is risk; we surface and score it. |

Specific Gaps by Competitor
| Gap |
What This Means |
Related Claims |
Verified |
| No deterministic replay |
A scan from last month cannot be re-run to produce identical results. Feed drift, analyzer changes, and non-deterministic ordering break reproducibility. Auditors cannot verify past decisions. |
DET-003, COMP-TRIVY-002, COMP-GRYPE-001, COMP-SNYK-001 |
2025-12-14 |
| No lattice/VEX merge |
VEX is either absent or treated as a suppression filter. When vendor says "not_affected" but runtime shows the function was called, these tools can't represent the conflict—they pick one or the other. |
COMP-TRIVY-001, COMP-GRYPE-002 |
2025-12-14 |
| No signed reachability |
Reachability claims are assertions, not proofs. There's no cryptographic binding between "this CVE is reachable" and the call path that proves it. |
COMP-GRYPE-001, REACH-002 |
2025-12-14 |
| No semantic diff |
Tools report "+3 CVEs" without context. They can't say "exploitable surface decreased despite new CVEs" because they don't track reachability deltas. |

Elevator Pitches (by Audience)
| Audience |
Pitch |
| CISO/Security Leader |
"Stella Ops turns vulnerability noise into auditable decisions. Every verdict is signed, replayable, and proves why something is or isn't exploitable." |
| Compliance/Audit |
"Unlike scanners that output findings, we output decisions with proof chains. Six months from now, you can replay any verdict bit-for-bit to prove what you knew and when." |
| DevSecOps Engineer |
"Tired of triaging the same CVE across 50 images? Stella deduplicates by root cause, shows reachability proofs, and explains exactly what to fix and why." |
| Air-gap/Regulated |
"Full offline parity with regional crypto (FIPS/GOST/SM/eIDAS). Sealed knowledge snapshots ensure your air-gapped environment produces identical results to connected." |

Objection Handlers
| Objection |
Response |
Supporting Claims |
| "We already sign SBOMs." |
Great start. But do you sign call-graphs and VEX decisions? Can you replay a scan from 6 months ago and get identical results? We do both. |
DET-001, REACH-002 |
| "Cosign/Rekor is enough." |
Cosign signs artifacts. We sign decisions. Without deterministic manifests and reachability proofs, you can sign findings but can't audit why a vuln was reachable. |
DET-003, REACH-002 |
| "Our runtime traces show reachability." |
Runtime is one signal. We fuse it with static call graphs and VEX lattice into a signed, replayable verdict. You can quarantine or dispute individual edges, not just all-or-nothing. |
REACH-001, VEX-002 |
| "Snyk does reachability." |
Snyk's reachability is language-limited (Java, JavaScript), SaaS-only, and unsigned. We support 6+ languages, work offline, and sign every call path with DSSE. |
COMP-SNYK-002, COMP-SNYK-003, REACH-002 |
| "We use Trivy and it's free." |
Trivy is excellent for broad coverage. We're for organizations that need audit-grade reproducibility, VEX reasoning, and signed proofs. Different use cases. |
COMP-TRIVY-001, COMP-TRIVY-002 |
| "Can't you just add this to Trivy?" |
Trivy's architecture assumes findings, not decisions. Retrofitting deterministic replay, lattice VEX, and proof chains would require fundamental rearchitecture—not just features. |
