InvisiCloud
Confidential, S3-compatible object storage · now onboarding early-access deployments

Tell your customers “we cannot read your data” — and mean it.

InvisiCloud lets B2B SaaS vendors truthfully remove themselves from their customers' data — without rearchitecting the product. Your customer (or a partner) holds the key; you just point your existing S3 client at a new endpoint.

Security questionnaire

“Can your staff access our uploaded files? Where are the encryption keys?”

We are cryptographically unable to read your data. The key stays with you; our infrastructure only ever handles encrypted payloads.

The stuck deal

A real deal is stalled in security review

When you sell into health, legal, HR, fintech, govtech, or supply-chain buyers, the security review decides the deal. The questions that stall it look like this:

Can your staff access our data?

Where are the encryption keys held?

How do you handle Schrems II and international transfers?

Rearchitecting for client-side encryption isn't an option — and today's alternatives don't answer the question:

Client-side encryption

Breaks sharing, presigned links, and product features — and forces you to rearchitect the application.

BYOK / SSE-KMS

Improves key control, but the cloud provider still encrypts the data and could reach the keys. Provider and vendor stay inside the trust boundary.

Confidential computing

A hardware and attestation project, not a storage answer — and not something you can ship this quarter.

Why InvisiCloud

Revenue enablement, not insurance

InvisiCloud is bought to win competitive RFPs and pass security questionnaires — not primarily as breach protection.

Win the deal

“We are cryptographically unable to read your data” becomes a differentiated, truthful line item in RFPs and security questionnaires — the answer that unblocks stalled enterprise and public-sector deals.

No rearchitecting

Works with the standard S3 SDKs — AWS SDK, boto3 — and your existing application code. Integration is a DNS/endpoint change plus running one stateless container. No client-side key management.

Sovereignty as tailwind

Supports GDPR data-protection-by-design and supplementary-measures strategies for international transfers. Keep your hyperscaler — remove it, and yourself, from the plaintext trust boundary.

How it works

Zero-trust storage, split across two independent parties

No single infrastructure operator — Gateway, Key Server, or storage backend — can decrypt customer object contents on its own.

Your application
Existing S3 SDK — AWS SDK, boto3
InvisiCloud endpoint
A DNS / CNAME change
TLSHare · Secure Multi-Party Computation
InvisiCloud Gateway
utilacy-operated · processes encrypted payloads, holds no keys
Key Server
You or a partner · holds the keys, never receives payloads
Encrypted storage
One or more backends of your choice

Built on the patented TLSHare protocol and Secure Multi-Party Computation. The Key Server holds the TLS private key and KMS/HSM-backed master key but never sees payloads; the Gateway processes encrypted payloads but never holds keys. Neither party alone can reconstruct plaintext — data stays protected as long as both are not compromised at the same time.

Flagship use case

Confidential customer-document storage for B2B SaaS

Store the files your customers upload with the vendor and all infrastructure providers removed from plaintext access — while the product keeps behaving exactly as it does today.

User-uploaded documents

Contracts, patient records, HR files, case files — stored through your existing S3 code path, with you and every infrastructure provider cryptographically removed from plaintext access.

Sharing keeps working

Identity-based sharing and presigned links keep functioning — no second-channel key distribution, no client-side key management.

Revocation keeps working

Revoke access the way you do today. No long-term keys live on client devices.

Multi-backend redundancy

Connect one or two storage backends of your choice. Provider-independence and redundancy come built in.

Where this is going: the same two-party model extends toward confidential analytics (Apache Iceberg, PyIceberg) and confidential compute — future-facing directions we're building toward, not products available today.

The CISO questions

What a security team will ask

BYOK improves key control, but the cloud service still encrypts the data and could access the keys — the provider and the vendor stay inside the trust boundary. InvisiCloud removes both.

What we're honest about

InvisiCloud is early access and it is technical infrastructure — not a replacement for legal assessment, IAM, or organizational controls. Straight answers on the edges:

  • Metadata — object names, sizes, access timing, IPs — remains visible.
  • Authorized users or compromised credentials can still exfiltrate data they are allowed to access.
  • The Key Server is security-critical for availability and access control, even though its compromise alone does not expose plaintext.
  • No external cryptographic audit or academic review yet; performance testing is ongoing.

Scope your first deployment against a stuck deal

Get early access and we'll scope your first deployment on one bucket, one document workload — against a concrete deal in security review. We're onboarding early-access deployments now.
