Privacy isn't a
feature.
It's the foundation.

Privantium is the cryptographic privacy layer that sits between your users and every AI model — so intelligence never comes at the cost of trust.

AI Gate

The intelligent privacy gateway for every AI request

AI Gate sits at the perimeter of your AI infrastructure, inspecting every prompt and response in real time. It detects, classifies, and neutralises sensitive data before it reaches any model — the first line of defence with zero configuration overhead.

  • Real-time prompt inspection & PII redaction
  • Drop-in proxy — no SDK, no code changes
  • Compatible with any LLM provider or endpoint
  • Policy-driven routing: allow, block, transform
  • Sub-millisecond latency impact

Shield

Deep runtime privacy protection for production AI systems

Shield goes beyond the gateway. It wraps your entire AI pipeline with cryptographic protection — anonymising data at rest, in transit, and in use. Built for regulated industries that need verifiable proof of compliance without slowing operations.

  • End-to-end cryptographic anonymisation
  • BYOK encryption — your keys, your control
  • ZK-SNARK audit proofs on every interaction
  • HIPAA, SOC2, PCI-DSS, GDPR out of the box
  • On-premise & VPC deployment ready

How it works

Three steps to invisible privacy

Intercept & Identify

Privantium's proxy layer intercepts every prompt in real time, detecting PII, sensitive context, and regulated data before it ever reaches the model.

→

Anonymize & Shield

Sensitive tokens are replaced with cryptographic aliases. The AI sees context — never identity. Responses are de-aliased before returning to your user.

→

Audit & Prove

Every interaction generates an immutable audit trail with zero-knowledge proofs — so you can demonstrate compliance without revealing a single byte of user data.

Architecture

The three-layer shield

Every query passes through three distinct cryptographic strata, each independently hardened and auditable.

Layer 1 · Surface

Detection Layer

Real-time semantic analysis identifies sensitive patterns across 140+ data categories, including HIPAA, GDPR, PCI-DSS, and custom enterprise policies.

  • Named Entity Recognition
  • Contextual PII detection
  • Policy engine (YAML/JSON)
Layer 2 · Core

Transformation Layer

Sensitive tokens are replaced with format-preserving, reversible cryptographic aliases using AES-256 + HMAC-SHA3 under your keys — never ours.

  • Format-preserving encryption
  • BYOK (Bring Your Own Keys)
  • Sub-millisecond transform
Layer 3 · Foundation

Proof Layer

Zero-knowledge circuits generate cryptographic compliance proofs stored on a tamper-proof ledger. Regulators get proof. Users keep privacy.

  • ZK-SNARK audit proofs
  • Immutable compliance ledger
  • One-click regulator export

Trust by design

Built for the enterprises that cannot afford a breach

Healthcare. Finance. Legal. Government. The sectors where AI's upside is greatest — and where a single privacy failure is existential. Privantium was designed for these environments first.

  • No data retentionYour prompts and responses are never stored on our infrastructure.
  • Model agnosticWorks with OpenAI, Anthropic, Gemini, Mistral, and any custom model endpoint.
  • On-premise readyDeploy entirely within your VPC. Air-gapped installations available for classified environments.
