What We Solve

Voice AI needs a forensic trust layer.

Cipher gives your voice agents situational awareness, pairing real-time trust scoring with guardrails that stop leaks before they happen.

No cognitive verification

Name != identity + authorization.

Voice agents can match a name to a record, but they can't attest that the caller truly controls the account or has authorization.

Sensitive data leaks

PHI/PII exposed mid-call -> fines & lawsuits.

Without a trust signal, agents overshare. Every disclosure of protected health or financial data invites regulatory action.

Prompt-injection & vishing

Voice-based social engineering attacks.

Attackers manipulate scripted prompts, language models, and human supervisors to release restricted information instantly.

Manual QA overload

Post-hoc redaction != real-time prevention.

Teams drown in manual reviews after the damage is done. Cipher spots and stops the risky moment while it's happening.

High liability

One breach can cost $8K-$20M per incident.

Large fines, class-action suits, and brand erosion follow a single slip. Enterprises need proactive, explainable guardrails.

Streaming Trust Engine

Know Who You're Talking To

Voice agents lack real-time caller verification. Cipher provides a live trust probability—fusing identifiers, behavioral cues, and external corroboration—so agents know when it's safe to share PHI/PII.

Trust Verification Features

Caller Identity Verification

Real-time verification of who's calling through multi-factor evidence collection

Live Trust Score Calculation

Continuously updated probability score showing when it's safe to share PHI/PII

Evidence Fusion Engine

Combines identifiers, behavioral cues, CRM matches, and registry checks for accurate trust assessment

Regulated Industry Protection

Built for healthcare, finance, and legal industries with 7-8 figure breach liability

Plain-English Explanations

Understand why trust scores change with clear, actionable reasoning for each decision

Prompt Injection Defense

Detect and block manipulation attempts across different languages in real-time voice conversations

Cipher Platform

The bridge between your voice AI and enterprise systems.

Cipher sits between the agent and your data stack, delivering live trust scoring, data access control, and customizable guardrails tuned to your risk tolerance.

Voice AI Connectors

Drop-in proxy for ElevenLabs, Vapi, Retell, Twilio, and custom voice stacks. Cipher observes conversations without rewriting your agent.

  • Streaming transcripts
  • Signal extraction
  • Language-agnostic

Trust & Evidence Engine

Calibrated probabilities continuously update as new identifiers, behavioral cues, and registry checks arrive (<100 ms latency).

  • Multi-signal fusion
  • Explainable reasoning
  • Plain-English audit trail

Enterprise Guardrails

Connect to CRM, EHR, and policy systems to enforce per-client guardrails that decide what can be said, redacted, or escalated.

  • PHI / PII gating
  • Policy automation
  • Compliance logging

Guardrails you can explain to auditors.

Every decision is logged with rationale, artifacts, and a replay of the trust score trajectory so risk teams and regulators understand why data moved or stayed sealed.

How Cipher Runs the Call

A familiar timeline, now with just enough detail to see how effortless the trust layer is.

01

Connect in minutes

Drop Cipher between your existing voice agent and telephony stack—no prompt rewrites or workflow changes required.

02

Fuse every signal

Streaming transcripts, caller metadata, and enterprise systems feed one trust brain that knows who is on the line.

03

Stream live confidence

Cipher continuously updates a trust score so your agent understands when to continue, slow down, or escalate.

04

Enforce your policy

Guardrails you configure hold PHI, PII, and sensitive actions until confidence clears the thresholds you set.

Custom Guardrails

Real-time intervention for real-world scenarios.

Tailor rules to detect and act on client-specific events. Cipher executes them asynchronously so your voice AI stays confident and compliant.

Safety-critical

Self-harm or medical emergency

Auto-trigger escalation workflows, page clinical staff, or bridge in a human responder without losing context.

Compliance

Unauthorized PHI disclosures

Mute the agent, redact transcripts, or re-prompt instantly when the caller hasn't cleared the trust threshold.

Security

Prompt injection attempts

Quarantine malicious instructions, reset context, and resume the conversation safely in the correct language.

Policy

Dynamic compliance layers

Adapt HIPAA, PCI, SOC2, and client-specific policies per account, logging every decision for audit review.

Why enterprises choose Cipher

The trust layer voice AI has been missing.

Cipher replaces reactive, manual controls with proactive intelligence that keeps sensitive conversations safe.
