Sensitive data. Accountable by design.

Don't Just Protect Data. Prove It.

EpositBox is building a new approach to sensitive-data custody, helping organizations control access, preserve lineage and verify the integrity of critical records across applications, infrastructure and AI-driven workflows.

Designed to complement existing applications and cloud environments.

The challenge

Protection alone does not establish proof.

Sensitive information is copied, moved and processed across applications, databases, cloud services, backups, vendors and AI workflows. Security teams need more than a policy or an audit log. They need a reliable way to govern custody and verify what happened.

When a critical record is questioned, can you demonstrate its history and integrity?

Fragmented access

Permissions and identities can vary across systems and data stores.

Uncontrolled copies

Sensitive records may spread into backups, exports, logs and integrations.

Incomplete lineage

It can be difficult to reconstruct where data moved and how it was handled.

Evidence gaps

Organizations need defensible ways to verify integrity and document access.

The platform

Custody, identity and proof, working together.

EpositBox brings together a custody architecture and an identity-and-access foundation to support controlled handling of sensitive data and verifiable records of critical activity.

Custody architecture

STRINGS™

The evidentiary custody platform designed to connect controlled data handling with lineage, integrity checks and verifiable evidence, without requiring organizations to replace every application.

Identity & access engine

ZKIAM™

Zero-Knowledge Identity and Access Engine. The STRINGS foundation for identity-aware authorization and controlled machine-to-machine access to sensitive records.

The engine

ZKIAM™ zero-knowledge identity and access engine

Zero-knowledge identity and access, under every module.

ZKIAM™ is the zero-knowledge identity and access engine the STRINGS system runs on.

STRINGS does not replace your applications or your cloud. It sits underneath them as the layer where custody, lineage, and proof are enforced by architecture rather than policy.

Access to a sealed record is machine-to-machine and cryptographically proven, without exposing the record to prove it. No standing privileges, no shared credentials, no human path to the underlying data. Every access decision becomes part of the evidence rather than a gap in it.

How it works

From sensitive data to verifiable evidence.

A conceptual lifecycle for governing a sensitive record from authorization through later verification.

01 / Classify

Identify

Determine the record, sensitivity and applicable handling requirements.

02 / Authorize

Control access

Evaluate identity, entitlement and the requested operation.

03 / Protect

Seal or fingerprint

Apply appropriate cryptographic controls to support integrity verification.

04 / Trace

Record custody

Maintain relevant lineage and evidence records across the workflow.

05 / Verify

Produce evidence

Verify integrity and present the available history for review.

Solutions

Built for data that carries real consequences.

Focus on high-value use cases where sensitive information, accountability and evidence matter.

Architecture principles

Proof without putting everything on the blockchain.

Sensitive documents and operational data can remain off-chain. Where appropriate, cryptographic hashes, timestamps or verification metadata may be anchored to a ledger to support independent integrity checks. The architecture should use the right mechanism for each requirement, not blockchain for its own sake.

Discuss the Architecture ↗
  • Keep sensitive payloads separate from verification metadata where appropriate
  • Support cryptographic integrity checks and record verification
  • Design around existing applications, APIs and cloud infrastructure
  • Make trust boundaries, key management and evidence limits explicit

EpositBox · About the Numbers

The cost of losing control of data.

Data breaches are no longer isolated IT incidents. They can become legal, financial, operational and reputational events that continue long after the initial compromise.

3,000+

U.S. data-breach class actions were reported in 2025 in some industry counts, illustrating the scale of litigation risk surrounding compromised data.

The litigation trend

Available litigation analyses show a substantial increase in breach-related class actions. Exact totals vary by methodology, including whether related cases and privacy claims are counted separately.

~604

Reported breach class actions, 2022

~1,320

Reported breach class actions, 2023

~1,488

Reported breach class actions, 2024

~1,822

Reported breach class actions, 2025

The important number isn't just the breach.

The economic exposure can extend across litigation, regulatory response, notification, credit monitoring, remediation, customer support, business interruption, security investments and reputational damage.

What major breaches can cost

Selected high-profile examples demonstrate the potential scale of post-breach litigation and settlement exposure.

CompanyApprox. records affectedReported settlement / resolution
Equifax147 million$700M
T-Mobile76 million$350M + $150M security investment
AT&T—$177M
Yahoo—$117.5M
Marriott—$52M
MGM Resorts37 million$45M
Anthem79 million$115M

Four years. Billions in exposure.

Based on the settlement figures compiled in our analysis, the selected top-10 breach settlements represented approximately $719.2M in 2022, $515.8M in 2023, $593.2M in 2024 and $515.8M in 2025.

Why the numbers matter

Data has become a liability.

The more sensitive information an organization stores, copies, transfers and shares, the greater the potential blast radius when that information is compromised.

Security after the breach is expensive.

Organizations frequently have to spend heavily on investigation, remediation, monitoring, infrastructure changes and enhanced security controls after an incident.

Proof matters.

Organizations increasingly need to demonstrate not only that data was protected, but where it came from, who accessed it, what happened to it and whether its integrity can be established.

Prevention changes the economics.

EpositBox is designed around controlled custody, lineage and proof, helping organizations reduce the opportunity for unauthorized access and improve their ability to demonstrate what happened to critical data.

Research note: Breach counts and litigation totals vary by source and methodology. Settlement amounts may represent class-action settlements, regulatory resolutions, security commitments, or combinations thereof.
