The most sophisticated cold storage architecture is rendered worthless by a single social engineering attack, a compromised device, or an exposed key ceremony. For high-net-worth individuals, the threat surface extends far beyond the digital — physical security, personal information hygiene, and travel behaviour are all attack vectors.
CryptoVault provides bespoke OPSEC consulting that addresses the human layer of security. Our engagements cover individual executives, family principals, and the operational procedures of entire organisations.
Bespoke threat assessments covering digital, physical, and social engineering attack vectors relevant to your specific profile.
Hardening of all devices used in proximity to digital asset management, including air-gap procedures and network segmentation.
Design and execution support for multi-signature key ceremonies — the highest-risk operational event in self-custody.
Personalised programmes covering OPSEC fundamentals, travel security, and communications hygiene for principals and executives.
Pre-defined incident response playbooks for custody breach, key compromise, and social engineering scenarios.
Due diligence on all third-party services, vendors, and advisors with access to or knowledge of digital asset holdings.
Public figures, executives, and known investors whose digital asset holdings make them high-priority targets for sophisticated threat actors.
Organisations where multiple principals, staff, and advisors have varying degrees of access to digital asset infrastructure.
Crypto-native funds and digital asset businesses requiring operational security frameworks for internal key management and staff protocols.
Operational Security (OPSEC) is the discipline of managing information about yourself and your activities to prevent adversaries from using that information against you. For cryptocurrency holders, OPSEC addresses the gap between cryptographic security (which protects against remote attacks on your keys) and physical security (which protects against attacks on you personally). Bitcoin cannot be seized by a hacker who cannot access your keys — but it can be seized by someone who forces you, at physical risk, to hand over access. OPSEC reduces the likelihood that you become a target and reduces the effectiveness of an attack if one occurs.
Physical attacks on cryptocurrency holders rose 169% in the first six months of 2025 compared to the previous year. The perpetrators are organised, patient, and specifically targeting individuals known or suspected to hold significant digital assets. Victims have been identified through public blockchain analytics, LinkedIn profiles, property records, conference attendance, and social media. The threat is not opportunistic — it is intelligence-led.
The baseline protective measures include: not publicly disclosing digital asset holdings or valuations; using a business or trust entity rather than a personal name for any digital asset-related activities; maintaining separation between your digital asset identity and your personal identity; implementing robust physical security at your primary and secondary residences; using secure communication channels for all digital asset-related discussions; and ensuring that a physical attack on you alone cannot yield access to your assets — which requires multi-signature custody where you alone cannot authorise a transaction.
Our OPSEC assessments evaluate your current exposure across four dimensions: information exposure (what information about you and your holdings is publicly available and accessible to adversaries); physical security (the adequacy of your personal and property security relative to the threat profile of a targeted digital asset holder); operational practices (how you conduct digital asset transactions, store access credentials, and communicate about your holdings); and custody architecture (whether your custody setup ensures that a physical attack on you personally cannot yield access to your assets).
