End-to-end encryption (E2EE) solutions

Many names, one concept. End-to-end encryption, Zero-knowledge protocols and architectures, zero-trust access control and security solutions all address one thing: building systems with elevated security requirements, where only trusted agents are allowed to access the data.

The challenge of E2EE / Zero Trust solutions is the combination of security, maintainability and flexibility, which doesn't ruin UX.

Challenges that require E2EE solutions

Hard to control

Huge heterogeneous infrastructures with tons of components and weak perimeter in "we can't be sure what's trusted" state.

Elevated risks

Compliance requirements or real-world risks that require minimisation of attack surface and maximisation of protection and visibility.

Insider threats

E2EE and Zero Trust systems have defenses "outside" and "inside", protecting data from curious employees, leaving no opportunities for insiders.

Modern end-to-end encryption solutions

Modern crypto protocols

Zero-knowledge proof protocols allow parties to process the data together without revealing it to each other or 3rd parties. This minimises the exchange of plaintext data inside the system.

Zero Knowledge Architectures

ZKA is a design principle that facilitates building products with no access to customer data, be it directly or via inference. ZKA can be built on top of end-to-end encryption.

Zero Trust access control

Systems that don't have a "trust perimeter". All components are required to verify access on every transaction based on the security-relevant context of this transaction.

Our offerings

End-to-end encryption software

Acra

A DATABASE SECURITY SUITE

Acra offers a selective and searchable encryption which is easy-to-integrate in already-built infrastructures. Acra can be used in E2EE / Zero Trust systems, efficiently applying encryption & other security controls to the data flow without significant alterations of the architecture.

Themis

A CROSS PLATFORM CRYPTO LIBRARY

A security framework for end-to-end encrypted data flow. Hermes provides cryptographically protected data processing and data collaborating without the need to re-encrypt an excessive amount of data.

Custom design and implementation

Zero Trust and Zero Knowledge systems

We design distributed systems, which reinforce/verify their security guarantees using End-to-End encryption, Zero-knowledge proofs or similar cryptographic approaches.

End-to-End Encryption layers

We design & implement End-to-End Encryption schemes with key management tailored for your use case, technical stack and UX.

Differential privacy systems

Various techniques from privacy-enhancing cryptography, coupled with differential privacy, are naturally suited to resolve challenges in multi-party and interactive scenarios, avoiding the sharing of data across parties.

Consulting

Designing architecture for your use case

Measure twice, cut once. Before migrating to E2EE / Zero Trust, one should spend time designing new architecture, re-thinking current approaches and working on a migration guide. Our security architecture and SRE expertise can help your team.

Reviewing application security

Reviewing and ensuring that product, application and infrastructure security enforces the right type of security guarantees are essential for Zero Trust tooling to be efficient.

Product security strategy

It's tricky to correlate security matters to your product growth plan when you're aspiring for a business. Good security strategy mitigates cybersecurity risks without compromising on the usability and flexibility of your solutions.

Business impact

User trust

Your company doesn't have access to users' data. At the same time, the end-to-end encryption layer is integrated into app flow without breaking UX.

Decreased cognitive load

Zero Trust, Zero Knowledge systems are hard to build, maintain and control. Our experience allows making them developers and Ops friendly.

Simpler compliance

Controlled data flows inside strict security tools is easier to validate with auditors. Plaintext data can't be unnoticeable leaked if it's almost never in plaintext.

Reduced risk

Zero Trust, Zero Knowledge systems radically decrease the attack surface for data and access and improve visibility.
