Gain Confidence.
We audit designs, specifications, protocols, and implementations for teams building cryptography, trusted compute, digital identity, payments, authentication, and other high-assurance systems.
Tailored Assessment
Assurance work should match the system, the stage of development, and the decision you need to make.
Before Implementation
Review architecture, assumptions, threat models, and primitive choices before they harden into product constraints.
Before Launch
Audit code, specifications, circuits, protocols, deployment flows, and integrations before users depend on them.
After Findings
Validate fixes, answer implementation questions, and make sure remediation addresses the underlying issue.
Across Disciplines
Combine cryptography, trusted compute, application security, distributed systems, and product context when the system requires it.
Areas Of Expertise
We focus on systems where mistakes are hard to detect, expensive to fix, and difficult to reason about without specialist review.
Applied Cryptography
Protocols, signatures, encryption, key management, post-quantum migrations, and primitive selection.
Zero-Knowledge Proofs
Circuits, arithmetization, proof systems, verifier implementations, and protocol integration.
Trusted Execution Environments
TEE design, enclave review, AWS Nitro Enclaves, Intel TDX, remote attestation, key release, and hardware-backed trust assumptions.
Identity And Credentials
Digital identity, authentication, credentials, wallets, age verification, and privacy-preserving claims.
Payments And Finance
Payment flows, custody-adjacent systems, transaction authorization, compliance-sensitive cryptography, and financial protocols.
Distributed Systems
Consensus-adjacent protocols, distributed trust, cross-system assumptions, and security-critical coordination logic.
How Engagements Work
You get a predictable process, regular communication, and deliverables that engineering and leadership can both use.
Technical Onboarding
We map the system, collect the relevant artifacts, identify review goals, define assumptions, and agree on what assurance should mean for the engagement.
Kickoff And Review
We start with a shared understanding of scope, then run the review with direct access to reviewers and early reporting for issues that need immediate attention.
Status And Readout
You get regular status, a final readout, and a written report with findings, severity, impact, reproduction notes, design feedback, and prioritized recommendations.
Fix Review
We validate fixes, answer follow-up questions, and help turn the review into durable engineering knowledge.
The Deliverable
A software assurance engagement ends with a report that engineering teams can act on: background for the system under review, scope, methodology, findings with severity, reproduction notes, actionable recommendations, client responses, and the evidence needed to make decisions.
