Services
Some teams arrive with a defined system, workflow, contract, or control surface that needs review. Others need to design a custody workflow, test network and infrastructure attack paths, 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, networks, 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
External and internal testing across network perimeter, internal paths, cloud and hybrid infrastructure, segmentation, remote access, privileged access, and operational controls.
Best when: you need to understand how attackers could move through external, internal, cloud, remote-access, or privileged infrastructure paths.
Discuss Network Testing03
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 Assessment04
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 Design05
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 Review06
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, or operational concern.
Discuss custody integration review07
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 Advisory08
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 Diligence09
Practical training, secure-design workshops, workflow exercises, phishing-readiness exercises, key ceremony rehearsals, operational 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.
Discuss Training & ExercisesStarting point
If the first review target is unclear, Guvenkaya can help identify the right starting point before you commit to a larger review, assessment, design, or advisory engagement.
