AI doesn't hack your files.
It just reads them.
Every company, platform, and tool your files touch has AI that can read them. Your lawyer's Copilot. Your vendor's Glean. Their Confluence AI. Your files pass through five AI systems before they reach the person you sent them to.
CypherFile encrypts every file at the source and binds access to a registered physical device. No phone, no access — for anyone, including AI.
The Problem Isn't Hackers.
It's Permissions.
90% of organizations have sensitive files exposed to all employees through AI copilots. That means salary data, board decks, wire instructions, and NDAs are already readable by AI — right now, using permissions that already exist.
You will never fix every permission. CypherFile protects the files that matter most — at the file itself.
Device-Bound: no registered device, no access.
Agent-Proof: physical unlock no AI can perform.
Zero Data Custody: files never touch Cyphlens servers.
Send Files the Same Way You Do Today
Encrypt & Set Access
Locally encrypt your file and choose who can unlock it. Wrap it in a lightweight package ready to send.
Send Over Any Channel
Email, Slack, Teams, Drive, SharePoint — use whatever channel you already use. No portals. No special tools.
Recipient Scans to Unlock
The recipient opens the file and scans a visual challenge with the Cyphlens app on their registered device. File decrypts locally. No integrations required — author and recipient only need the Cyphlens app.
Built for HIPAA-Regulated Workflows
CypherFile encrypts files before they leave your device and sends them directly to the recipient. Cyphlens never receives the file — not even in encrypted form.

The Files AI Should Never See
Every file your employees can access is a file an AI copilot can read. These are the ones that matter most.
Legal & Litigation
Discovery docs an AI agent can surface.
Case files, evidence packets, privileged communications, and NDAs pass through your client's AI tools, their vendor's AI tools, and every platform in between. CypherFile keeps them agent-proof across the entire chain of custody.
HR & Compensation
A salary band an AI copilot can summarize.
Offer letters, performance reviews, headcount plans, and comp benchmarks are exactly what AI copilots surface to the wrong people. Protect them at the file level, not the folder level.
Finance & Payments
Wire instructions an enterprise search tool can index.
ACH forms, account numbers, settlement docs, and invoices are high-value targets. Once indexed by an AI search tool, they're a query away from anyone with access.
Intellectual Property
Trade secrets an AI assistant can ingest and recall.
Patent drafts, source code, formulas, product roadmaps, and R&D data are exactly what AI assistants ingest and recall across sessions. CypherFile ensures they never fully decrypt without a registered device present.
Board & Executive
Board materials a forwarded email can expose.
Board decks, M&A materials, and investor updates have no protection once they leave your network. CypherFile keeps access revocable and auditable — even after forwarding to a hundred people.
You can't fix every permission. You can encrypt every file that matters.
