Suprbox
A security gateway that sits between your company's sensitive documents and AI agents, checking every access request against rules before letting anything through.

Description
Companies are starting to let AI agents read internal documents — contracts, HR files, customer records — to answer questions or automate work. The problem is that an agent doesn't know what it's allowed to see, and once it has read a file, there's no way to un-read it. Suprbox works like a locked filing cabinet with a strict clerk in front of it: every request from an agent (from Claude, ChatGPT, or a custom pipeline) has to pass a set of rules — is this the right kind of document, does it contain something like a social security number, is it within the allowed time window — before anything is handed over, and every request is written down in a permanent log.
Technically, Suprbox is a policy-gated data vault with per-vault AES-256 encryption and a zero-knowledge design, meaning Suprbox's own staff cannot read the documents stored in a vault. Access rules can check document classification, detected PII, keywords, rate limits, and time windows, and every read is recorded in an immutable audit log for compliance review. It integrates with Claude, OpenAI, Gemini, Llama, Mistral, LangChain, CrewAI, AutoGen, n8n, Zapier, and MCP, and the company reports SOC 2 Type II certification with annually audited reports.
💬 Our review
The short version: if your team is already piping sensitive documents into AI agents without a formal access layer, Suprbox plugs a real gap cheaply — the free tier (1 vault, 100 documents) is enough to see whether the policy model fits before paying anything.
Suprbox's honest comparison isn't really other data vaults, it's the fact most companies currently use nothing at all, or repurpose a secrets manager like HashiCorp Vault or AWS Secrets Manager that was built for API keys and passwords, not for policy-based document access with PII detection. Against those, Suprbox is purpose-built for the agent-reads-documents use case and adds the audit trail compliance teams actually ask for. The catch is that its paid tiers (Team at $49/user/month, Enterprise on request) are both still marked "coming soon" at the time of writing, so teams needing more than one vault or SSO can't fully commit yet, and the company itself is thin on public information — worth a pilot on the free tier before betting a compliance program on it.
