About DORTRESS

We build the cloud that cannot betray you.

DORTRESS Technologies builds the world's first unified, zero-knowledge, post-quantum cloud platform with private AI. Your files, messages, calls — encrypted on your device before they ever reach our infrastructure.

We hold ciphertext. You hold the keys. AI runs inside hardware-attested enclaves — even we cannot see plaintext. The only architecture where enterprise privacy meets AI without compromise.

"We would pay three times Sentinel Secure Chat's price if we could audit one vendor instead of four."

Global-First, India-Built

DPDP, GDPR, HIPAA, NIS2 ready. Sovereign data centres with global deployment. Your data encrypted everywhere — from device to storage to AI processing.

MeitY-empanelled data centres
Hardware-attested enclaves (Intel TDX, AMD SEV-SNP)
NIST FIPS 203/204/205 post-quantum standards
The DORTRESS Platform

Five pillars. One architecture.
Zero compromise.

Every service unified under a single zero-knowledge architecture, one identity layer, one audit trail, and one compliance posture.

Privacy Suite

Storage, Email, Chat, Video — zero-knowledge, post-quantum ready across every channel.

Phase 1 — GA 2026

Identity Platform

Zero-knowledge SSO, SCIM, device trust. 50–70% below Okta pricing.

Phase 1A

Compliance Engine

DPDP Pack, Assure CaaS, cryptographic audit trail built into every action.

Phase 1B

Developer Platform

Primitives API, Confidential Compute, vertical clouds for Legal, Health, and BFSI.

Phase 3+
Private AI — Confidential Compute

AI that doesn't read your data.
Seriously.

Microsoft Copilot creates CLOUD Act exposure. DORTRESS doesn't. All AI features run inside hardware-attested enclaves — Intel TDX and AMD SEV-SNP — so your plaintext never leaves the protected boundary.

Encrypted Semantic Search

Query processed inside enclave, results encrypted. The server never sees your query.

Meeting Transcription

Audio decrypted inside TEE, transcribed, re-encrypted — zero exposure at any stage.

Email Drafting Assistance

LLM runs inside enclave. Your drafts never leave the protected boundary.

Chat Summarisation

Action items extracted without reading conversation plaintext.

Document Classification

Automated PII detection for DPDP compliance, without data leaving your control.

Privacy-Preserving Analytics

Aggregated dashboards and insights without individual record access.

Competitive Advantage

Microsoft 365 + Copilot reads your data. Sentinel Secure Chat gives privacy without AI. DORTRESS delivers privacy with AI — the only platform that achieves both through confidential compute architecture.

Deployment Flexibility

Your infrastructure.
Our encryption. Every model.

No architectural compromises. Deploy where sovereignty demands — and our zero-knowledge guarantees follow.

Sovereign Cloud (Managed)

MeitY-empanelled data centres. India, Singapore, UAE, EU — ciphertext only.

Hyperscaler

AWS, Azure, GCP — ciphertext only stored. Zero CLOUD Act exposure by design.

Colocation

Your hardware. Our encryption layer and managed compliance stack on top.

On-Prem / Air-Gapped

Zero external connectivity. Full zero-knowledge guarantees without network dependency.

Our Philosophy

Six beliefs govern every product decision.

Cryptography Is Invisible UX never requires cryptographic expertise. Security is structural, not procedural.
Compliance Is Built-In Every action emits audit evidence automatically. No compliance retrofitting.
Suite Consistency Unified identity and policies across all applications. One control plane.
Sovereignty Is Structural Guaranteed by mathematics, not legal agreements that can be compelled.
Post-Quantum by Default NIST FIPS 203/204/205 shipped. Not a roadmap item — already in production.
Professional, Not Paranoid Built for CISOs, DPOs, and executives. Enterprise-grade UX, not hacker tools.
Pricing

One suite. One audit trail.
Four encrypted services.

Transparent pricing with no per-feature unlocks. Every tier includes the full zero-knowledge architecture.
