Security you can't compromise. Control you can't lose.

Your cases. Your clients. Your strategy. Bastion is built so your data never leaves your environment — ever.

  • Self-hosted — your evidence never touches a third-party cloud
  • Encrypted in transit, end to end
  • Per-user authentication with revocable access tokens
  • Every change audit-logged: who, what, when, before and after
  • Read-only evaluation accounts for controlled demos

Why firms pick Bastion

Most legal-tech tools are cloud-only subscriptions that hold your evidence on their servers. Bastion is different by architecture, not by promise:

  • Your infrastructure, your data — nothing to subpoena from a vendor
  • A citation firewall no general-purpose AI chatbot has
  • Native apps on macOS and iOS, not just a browser tab

Simple, transparent, per-seat pricing.

Bastion is deployed per firm, on infrastructure you control. Pricing depends on corpus size and seats — we'll scope it with you in one call.

For legal professionals only. Bastion is a litigation-support tool intended solely for licensed attorneys, paralegals, and legal staff working under attorney supervision. Bastion does not provide legal advice, and nothing in the platform creates an attorney-client relationship. AI output is research assistance only and must be independently verified by counsel before any use.
