Summary
Box excels at enterprise content management: permissions, workflows, e-signature integrations, and governance features aimed at large IT orgs. Compliance Locker focuses on a smaller job — encrypt documents in the browser, store ciphertext, share sealed links, and export access activity — without building a full content-cloud suite.
Side-by-side
| Topic | Compliance Locker | Box |
|---|---|---|
| Product category | Zero-knowledge B2B document vault | Enterprise content cloud / ECM-style platform |
| Encryption model | Client-side encryption before upload; keys derived locally from the master password | Strong platform encryption and optional customer-managed key options (verify current Box KeySafe / CMEK offerings with Box) |
| Zero-knowledge positioning | Core product design: plaintext sealed in the browser under normal operation | Enterprise security and governance first; zero-knowledge is not the primary product story |
| Sharing | Password-optional sealed links with expiry, view limits, and watermark options | Mature external collaboration, shared folders, and enterprise sharing policies |
| Audit trail | Insert-only application audit activity for vault events | Deep enterprise audit and reporting suited to large IT programs |
| Integrations & workflow | Focused vault + org seats + billing — not a broad app marketplace | Extensive integrations, Box Relays / workflows, and partner ecosystem |
| Compliance marketing | Honest Trust Center; no fake SOC 2 / HIPAA badges | Extensive published compliance resources (confirm current reports with Box) |
Choose Compliance Locker when
Teams that want a dedicated sealed vault with explicit zero-knowledge boundaries and lightweight sharing, without adopting a full ECM platform.
Choose Box when
Enterprises standardizing on Box for collaboration, retention, and vendor-integrated workflows across many departments.
Practical notes
- Choose Box when you need platform breadth (workflow, many connectors, enterprise IAM patterns).
- Choose Compliance Locker when the buying question is specifically “vendor can’t read the files.”
- Box Shield and related controls are valuable — they solve a different layer than client-held vault keys.
