Services
Some teams arrive with a defined system, workflow, contract, or control surface that needs review. Others need to design a custody workflow, challenge an architecture decision, prepare for diligence, or clarify risk for leadership. Guvenkaya helps match the situation to the right review, assessment, design, or advisory engagement.
01
Focused technical reviews of applications, infrastructure, custody models, smart contracts, blockchain systems, AI systems, operational controls, and diligence targets.
Best when: you have a system, workflow, contract, or control surface that needs findings, risk context, and remediation guidance.
Discuss a Security Review02
Executive-grade posture assessment across systems, vendors, people, workflows, and controls for boards, leadership teams, regulators, auditors, insurers, investors, and institutional customers.
Best when: leadership needs a board-ready view of where security risk concentrates and what to fix first.
Discuss a Risk Assessment03
Design or challenge security-critical systems, workflows, integrations, custody models, key ceremonies, and operating controls before development, launch, or major change.
Best when: you are still shaping system architecture, sensitive workflows, custody, signing, approval, recovery, vendor integration, or go-live controls.
Discuss Architecture & Process Design04
Review or challenge custody architecture, wallet and signing workflows, key lifecycle, approval flows, recovery paths, role separation, and vendor dependencies before launch or major change.
Best when: digital value is being stored, moved, approved, recovered, or governed.
Discuss a Custody Review05
Security design and production review for custody platforms and key-management systems integrated into digital asset workflows.
Best when: a custody platform or key-management system is being selected, integrated, launched, migrated, or reviewed in production after growth, audit, incident, or operational concern.
Discuss custody integration review06
Advisory for institutions and digital asset operators building, expanding, or reviewing custody, tokenization, settlement, wallet, and digital asset infrastructure.
Best when: the decision spans custody architecture, vendors, operating model, pre-launch review, or program governance.
Explore Program Advisory07
Security diligence for investors, acquirers, funds, ecosystem teams, and enterprise buyers evaluating a company, vendor, protocol, or platform.
Best when: you need security judgment before an investment, acquisition, vendor selection, grant, partnership, or strategic commitment.
Discuss Diligence08
Practical training, secure-design workshops, tabletop exercises, phishing-readiness exercises, key ceremony rehearsals, playbook exercises, and readiness drills for teams operating high-stakes digital systems.
Best when: the team needs better security judgment under real operating conditions, not another generic training session.
