Security Without Compromise
Five security disciplines. One methodology. Every engagement staffed by senior offensive engineers - winners of 30+ international competitions - directing rigorous manual review and frontier AI models as force multipliers. 300+ engagements across $120B+ in protected digital assets. Zero client exploits.

Blockchain audits, smart contract audits, protocol security reviews, exchange and wallet evaluations, and TEE application security. Conducted by multiple independent teams per engagement. Senior engineers armed with frontier AI models that extend code coverage across massive codebases and surface non-obvious interaction patterns at a depth manual-only review cannot match. Solidity, Rust, Move, Vyper. L1/L2 protocols. 300+ engagements. Zero client exploits.
CAPABILITIES
- Smart Contract Audit (Solidity, Rust, Move, Vyper, Cairo, etc.)
- L1/L2 Blockchain Security Review
- Centralized Exchange Security Assessment
- Hardware and Software Wallet Audit
- DeFi Protocol Security Review
- Bridge and Cross-Chain Security
- TEE Application Security Review

AI agents are executing transactions, pushing code, managing infrastructure, and making autonomous decisions with real money at stake. Hexens audits the systems the rest of the industry is still learning to name: agentic commerce protocols, MCP server deployments, LLM-powered applications, vibe-coded products, privacy-preserving AI, and autonomous systems operating in high-stakes environments. Same methodology. Same engineers. The attack surface that matters most right now.
CAPABILITIES
- AI Agent Security Audit
- Agentic Commerce & Payment Protocol Security
- MCP Server & Tool Integration Security
- LLM Application Security Assessment
- Vibe-Coded Application Security Audit
- MLOps Pipeline & Model Supply Chain Security
- AI Red Teaming

ZK circuits, where a single underconstrained signal can drain an entire protocol in one transaction. Fully homomorphic encryption schemes vulnerable to parameter misconfiguration and silent plaintext leakage. Multi-party computation protocols susceptible to malicious abort and input inconsistency. This is the cryptographic layer where implementation-level flaws carry catastrophic, often irreversible consequences. Hexens performed the first independent security audit of a zkEVM.
Our researchers operate at the mathematical layer where most auditors stop reading - proving systems, circuit constraint validation, field arithmetic, trusted setup ceremonies - armed with frontier AI that enables exhaustive exploration of constraint systems with thousands of gates. Circom, Noir, Gnark, Zokrates, PIL, zkASM, Cairo, and beyond.
CAPABILITIES
- ZK Circuit Security Audit (SNARKs / STARKs)
- FHE Implementation Review
- MPC Protocol Security Assessment
- Cryptographic Primitive Implementation Audit
- Proving System Implementation Review
- Post-Quantum Cryptography Assessment
[SRVC. 04]
The attack surface is the entire digital presence. Full-scope penetration testing, APT simulation, application security reviews, and infrastructure assessments where blockchain meets traditional systems. Every engagement is all-augmented, including AI with the most frontier models and techniques - senior OSCP/OSCE/OSWE-certified engineers direct frontier models to extend reconnaissance, map attack paths, and generate adversarial scenarios at a depth that redefines what a pentest can cover.
CAPABILITIES
- APT Simulation and Red Teaming
- Web Application Penetration Testing
- Mobile Application Security Assessment
- Source Code Review
- API Security Testing
- Cloud Infrastructure Security Audit
- Network Penetration Testing
[SRVC. 05]
Security that starts before the first line of code and extends beyond the audit report. Architecture design, threat modeling, compliance readiness, and operational security - our consultants are the same senior engineers who break protocols, now directing frontier AI to accelerate analysis and expand coverage across complex infrastructure. SOC 2, ISO 27001, MiCA, DORA.
CAPABILITIES
- System Architecture Review
- Threat Modeling and Risk Assessment
- Compliance and Certification Advisory
- DevSecOps Integration
- DDoS Resilience Assessment
- Social Engineering Training and Testing

Two Independent Teams. Rigorous Review. Frontier AI. Every Engagement.
Our team members are winners of 30+ international competitions, responsible for discovering critical vulnerabilities in industry-leading projects, and trusted to secure over $120 billion in digital assets.
Every engineer does rigorous manual review and directs frontier AI models as a force multiplier - extending code coverage, generating adversarial test cases, and reasoning about complex systems at a depth and pace that manual-only or automated-only approaches cannot match. Hexens deploy two such teams to every engagement in parallel. Findings are cross-verified, ensuring depth, breadth, and reassessing the blind spots.

Tailored Scoping Led by Senior Experts
Your engagement begins with a strategy session led by the same security researchers who will oversee the audit. We align on your system design, threat model, and specific risk profile - not a generic checklist.
[03.]
Beyond Scope, Beyond Standard.
Hexens deliver more than expected. Post-remediation retesting is always included, and we routinely identify critical out-of-scope issues - the result of a holistic approach where engineers understand your full architecture, not just the files in scope.
