Arkin Vault is a cloud workspace for sharing confidential documents under defined release conditions. Law firms, accounting and advisory practices, founders, and other teams can create secure exchange rooms and require an NDA, engagement letter, acknowledgement, or another condition to be completed before a recipient receives access. It is best suited to workflows where agreement status and a record of document handling matter as much as the file transfer itself, rather than to teams seeking a general-purpose storage service.

Its controls extend beyond the initial gate: the product supports recipient verification, per-recipient watermarking, expiry, view limits, revocation, and page-level access controls. Signing can happen in-browser, or teams can upload wet-signed documents or record completion through an external signing service. Arkin Vault logs views, downloads, print attempts, signing events, and administrative actions, then packages agreement, document, recipient, and access records into PDF and JSON evidence exports. User-defined retention rules and legal holds add document-governance options. This combination is most relevant when a team needs to show what was shared, with whom, and under which agreement; organizations that only need basic file delivery may find this specialized workflow unnecessary.

According to the vendor's pricing page, Solo costs $39 per month and includes an NDA gate, per-recipient watermarking, full audit trail and evidence packs, and email support. Practice is $99 monthly, adding connectors and Vault Folders, unlimited documents, and priority email support. Firm is $299 monthly, with unlimited active documents, API and webhooks, and priority support. Enterprise lists SSO / SAML, dual-region and data residency, DPA + BYOK, and dedicated support. There is no free plan; a 14-day trial requires a card. Google Drive is marked live, while several other listed connectors are still being built or planned. Choose Arkin Vault for agreement-gated releases and audit evidence; consider a simpler alternative if those controls are not central to your process.

Arkin Vault pros and cons

  • Where it wins
    • Requires an NDA or other agreement before documents are released.
    • Combines recipient verification, watermarking, expiry, view limits and revocation.
    • Exports agreement, document, recipient and access records as PDF and JSON.
  • Where it doesn't
    • No free plan; the 14-day trial requires a card.
    • Monthly plans start at $39, so it may not suit occasional sharing.
    • Several listed connectors are still being built or planned.
