Cybersecurity for digital asset operations
Digital asset systems fail differently from conventional IT. A stolen signing key is an irreversible transfer. A misconfigured smart contract is a public exploit. A compromised node is a false view of the ledger. Client Focus applies a security program designed for those failure modes, covering the keys, contracts, nodes, integrations and people that make up a digital asset operation, and runs it continuously through the C'ROC security operations center.
Protect
Security architecture and controls
Six control areas cover the keys, code, infrastructure, boundaries and people that a digital asset operation depends on.
Key and custody controls
Client Focus does not take custody of client assets and does not hold client signing keys. Key generation, storage and signing remain within the client's or its qualified custodian's environment. Client Focus operates with monitoring and alerting rights and, where contracted, proposes actions that the client's authorized approvers execute. Design and review of key management for hot, warm and cold tiers: hardware security modules, multi-party computation and multi-signature schemes, quorum and approval policies, key ceremony procedures, rotation and revocation, and the segregation of duties between initiators, approvers and operators.
Wallet and transaction policy
Allow-lists, velocity and value limits, time locks, address screening before signing, and policy engines that block a transaction that falls outside a client's stated operating pattern.
Smart contract security
Pre-deployment code review against known vulnerability classes (re-entrancy, access control, oracle manipulation, integer and precision errors, upgrade-proxy misuse), privileged-role inventories, pause and circuit-breaker design, and post-deployment monitoring of role grants and configuration changes.
Node, validator and RPC hardening
Host baselines, peer and port exposure, client diversity, slashing protection for validators, RPC authentication and rate limits, secrets handling, and verified builds for node software.
Integration and API security
Exchange, custodian, banking and payment integrations reviewed for authentication, replay protection, idempotency, reconciliation and rate control, because most losses begin at a boundary between systems.
Identity and access
Least-privilege roles across cloud, chain tooling and signing systems, hardware-backed MFA, just-in-time elevation, session recording for privileged actions, and periodic access reviews.
Detect and respond
Detection and response
Detection runs continuously. Response follows playbooks agreed before an incident, not written during one.
24/7 monitoring through C'ROC
On-chain activity for client wallets, contracts and counterparties is checked continuously against security rules, behavioral baselines and risk intelligence. Watch Officers validate every alert before it reaches the client. Notification within 10 minutes of detection; client acknowledgment within 15 minutes (targets stated in the client's service description).
Threat categories covered
Exploit-related fund movement, unauthorized privileged actions (role grants, configuration-flag changes, upgrades), laundering and mixer interaction, sanctions and high-risk exchange exposure, rug-pull and scam patterns, suspicious wallet behavior, de-peg and liquidity stress, and infrastructure signals such as node desync or RPC failure.
Incident response
Pre-agreed playbooks for contract pause, key rotation, withdrawal freeze, counterparty notification and exchange outreach; evidence preservation with hop-by-hop timestamps; fund-flow tracing and coordination with analytics providers, exchanges and law enforcement when recovery is possible.
Threat intelligence
Tracking of active exploit campaigns, drainer kits, phishing infrastructure targeting the client's brand and signers, and indicators shared across the watch floor.
Prove
Assurance and compliance
Controls are tested, mapped to recognized frameworks and evidenced for examiners and auditors.
Security assessments
Architecture reviews, penetration tests of web, cloud and integration layers, red-team exercises on signing workflows (including social engineering of approvers), and tabletop exercises with the client's incident team. Testing and assessment follow OWASP WSTG, OWASP MASVS, the OWASP Top 10 for LLM applications, NIST SP 800-115, PTES, MITRE ATT&CK and MITRE ATLAS.
Control frameworks
Controls mapped to SOC 2, ISO 27001, NIST CSF 2.0, PCI DSS for payment-adjacent systems, FFIEC guidance for banking clients, and GDPR for personal data. Client Focus is certified to ISO 27001; a SOC 2 Type II examination is underway.
Regulatory evidence
Monitoring records, incident timelines and access logs packaged for examiner and auditor requests under DORA (incident reporting and ICT third-party oversight), MiCA and the GENIUS Act implementing rules for stablecoin issuers.
Third-party risk
Due diligence and ongoing monitoring of the custodians, RPC providers, oracles, bridges and analytics vendors the client depends on, with documented exit plans.
Machine speed, human judgment
How AI is used in security
Models establish behavioral baselines for each wallet, contract and counterparty and flag departures in seconds. Detection agents correlate on-chain signals with risk intelligence and infrastructure telemetry, enrich each alert with context, and propose a severity.
A Watch Officer confirms the severity, decides the escalation and owns the outcome. No automated action that moves funds or changes a contract is taken without a named human approval.
