Security Consultancy
Architecture review, threat modeling, compliance readiness, and operational security for organizations building on blockchain. Security that starts before the first line of code and extends long after deployment.
Audits catch what's already built. Consultancy shapes what gets built next.
Hexens' advisory practice works alongside engineering teams on the decisions that determine whether a system is defensible from day one - or patched after the fact. Architecture design, threat modeling, compliance requirements, operational security, DevSecOps integration. The work that prevents vulnerabilities from existing in the first place.
Our consultants are the same senior engineers who run Hexens' audit practice - winners of 30+ international competitions, bug bounty leaderboard veterans, and researchers who have published original vulnerability disclosures. They bring an attacker's perspective into your design process, identifying structural risks that surface months or years after launch.
Every consulting engagement is augmented by frontier AI models under expert direction - enabling faster architecture analysis, more comprehensive threat modeling, and deeper coverage of configuration surfaces across cloud, network, and application infrastructure. Senior consultants spend less time on mechanical review and more time on the judgment calls that actually shape your security posture. The model handles breadth. The expert handles depth and decisions.
Our engineers hold OSCP, OSWE, OSEP, OSED, OSMR, OSCE3, ISO27001 LA and CRTL certifications - and more importantly, they apply those skills in the context of blockchain-specific threat models that traditional pentesting firms don't understand.

System Architecture Review
Security-focused assessment of your system’s architecture before development or during major redesigns. We evaluate trust boundaries, privilege separation, key management design, data flow integrity, and component interaction patterns - using AI-augmented analysis to map dependency chains and identify structural weaknesses that are expensive or impossible to fix once code is written. The goal is architecture that is defensible by design, not by patch.
Threat Modeling and Risk Assessment
Systematic identification of attack vectors, threat actors, and risk exposure specific to your protocol, platform, or infrastructure. We build threat models based on real-world attack patterns from hundreds of blockchain security engagements - augmented by AI-driven analysis that maps your system’s specific architecture against known exploit chains, emerging threat categories, and the attacker techniques we observe across the industry. Not theoretical frameworks applied generically.
Compliance and Certification Advisory
Guidance on regulatory compliance and security certification requirements for blockchain organizations - including SOC 2, ISO 27001, MiCA, DORA, and jurisdiction-specific digital asset regulations. We help teams translate regulatory requirements into concrete engineering controls and audit-ready documentation. Our consultants understand both the regulatory landscape and the technical implementation - and use AI-assisted analysis to accelerate gap assessments across complex infrastructure.
DevSecOps Integration
Embedding security into your development lifecycle - CI/CD pipeline security checks, automated vulnerability scanning, secure code review practices, dependency management, and incident response procedures. For blockchain projects, where deployed code is often immutable, catching vulnerabilities before deployment is critical. We build the processes that keep security consistent across releases, not just at audit milestones - including AI-augmented code review workflows that flag issues in real time.
DDoS Resilience Assessment
Evaluation of your infrastructure’s resilience against distributed denial-of-service attacks - covering network layer, application layer, and blockchain-specific attack vectors. We assess current defenses, identify single points of failure, and recommend hardening measures calibrated to your specific threat profile.
Social Engineering Training and Testing
Simulated social engineering campaigns targeting your team - phishing, pretexting, and operational security testing. Social engineering remains one of the most effective attack vectors in blockchain - several of the largest exploits in industry history began with a compromised team member, not a code vulnerability. We evaluate human-layer vulnerabilities and provide targeted training based on real attack scenarios.
