Twelve-axis governance scoring
Each axis is scored Yes / Partial / No / N/A against public evidence — vendor trust portals, BAAs/DPAs, SOC 2 report cover pages, published methodology documents. N/A applies when the axis is structurally inapplicable (foundation models, for example, defer Section 1557 to the downstream healthcare deployer).
| Axis | Status | EFROS note | Source |
|---|---|---|---|
| BAA / DPA available | Yes | Spellbook signs BAAs for enterprise customers where required. | Spellbook Security |
| Training-data opt-out | Yes | Spellbook does not train on customer documents. Tenant isolation enforced. | Spellbook Privacy |
| US data residency option | Partial | Spellbook hosted on US/Canada cloud infrastructure. Explicit US-only residency configuration not documented as of May 2026. | Spellbook Security |
| SOC 2 Type II report | Partial | Spellbook is SOC 2 Type II under audit / completed; report distribution via direct enterprise request. | Spellbook Security |
| ISO/IEC 42001 attestation | No | No ISO/IEC 42001 attestation. | Public posture review |
| NIST AI RMF self-attestation | No | No public NIST AI RMF self-attestation. | Public posture review |
| Colorado AI Act readiness | No | No Colorado AI Act-specific public statement. | Public posture review |
| HHS-OCR Section 1557 readiness | N/A | Legal-vertical positioning. | Spellbook positioning |
| FRB SR 11-7 readiness | N/A | Legal-vertical positioning. | Spellbook positioning |
| ABA Formal Op 512 readiness | Partial | Spellbook publishes general legal-ethics alignment documentation; explicit ABA Op 512 mapping less detailed than top-tier legal-vertical vendors. | Spellbook documentation |
| Subprocessor list public | Partial | Subprocessor information available via enterprise request; not self-serve public. | Spellbook Security |

Deep dive
Overview
Spellbook targets a smaller-firm market than Harvey, Lexis+ AI, or CoCounsel. The governance posture reflects the smaller-vendor scale — solid fundamentals on the dimensions that matter most for contracts (BAA, no-train) but less mature on trust-portal documentation, sector-specific governance, and AI-specific certifications.
Strengths
- BAA-eligible for enterprise
- Default no-train
- Word-integrated workflow lowers adoption friction
Weaknesses
- Less mature trust portal
- No explicit US-only residency configuration
- Subprocessor list NDA-gated
- ABA Op 512 mapping less detailed than top-tier legal vendors
Best-fit use case
Small-to-mid firms (5-50 attorneys) focused on transactional / contract work, where Word-integration and per-attorney pricing match the budget and workflow.
Avoid when
Firms with strict regulatory scrutiny (especially BigLaw or in-house teams under heavy compliance scrutiny) that need top-tier trust documentation.
Operator's take
Deploy Spellbook when small-to-mid firms (5-50 attorneys) focused on transactional / contract work, where Word-integration and per-attorney pricing match the budget and workflow. The composite score of 45 (grade D) reflects a mixed posture for regulated US workloads. Skip the vendor when firms with strict regulatory scrutiny (especially BigLaw or in-house teams under heavy compliance scrutiny) that need top-tier trust documentation. In every deployment, treat the cells above as a snapshot — the acquisition that gets to production safely is the one that re-verifies the trust-center posture before contract signature and rebuilds the matrix at renewal.
How this scoring is computed
The composite score blends eleven scoreable axes (BAA, training opt-out, US data residency, SOC 2, ISO/IEC 42001, NIST AI RMF, Colorado AI Act, Section 1557, SR 11-7, ABA Op 512, subprocessor transparency) with the trust-center maturity score. Axes marked N/A are excluded from the denominator so vendors are not penalized for sector-inapplicable axes. The vendor's primary sector amplifies the most relevant axes — healthcare vendors weight Section 1557 ×2, legal vendors weight ABA Op 512 ×2, banking vendors weight SR 11-7 ×2 — so the composite reflects what matters in the actual buying context.
