• Geographic Reach: Global

• BSV Integration Start Date: 2022

BUSINESS CHALLENGE

Cyberattacks are growing in both frequency and sophistication, costing businesses an average of $4.24 million per breach. Traditional cybersecurity systems suffer from significant detection delays—averaging 221 days to identify a breach—and rely heavily on manual log analysis and post-event investigations. These limitations expose organizations to prolonged vulnerability and prevent timely responses to security threats.

Existing Security Information and Event Management (SIEM) platforms also produce high false positive rates and lack tamper-proof audit trails, leaving room for manipulation and delays in accountability during incident reviews.

WHY BSV?

The BSV blockchain offers a secure, scalable, and cost-effective infrastructure ideal for high-frequency data logging with tamper-evident integrity. Key advantages include:

• High-frequency transactions: Capable of logging every 10 seconds.

• Data immutability: Ensures forensic-grade auditability of system changes and administrator actions.

• Low-cost micropayments: Enables frequent, timestamped writes to the blockchain without incurring prohibitive costs.

• Stable protocol and enterprise focus: The BSV blockchain is designed for predictable, enterprise-grade performance, ensuring long-term system compatibility.

Other blockchains were considered, but lacked the scalability, protocol stability, and transaction cost-efficiency that BSV provides.

SOLUTION ARCHITECTURE

Certihash’s Sentinel Node is a next-generation cybersecurity monitoring platform that overlays existing systems. It includes:

• File and log anomaly detection: Monitors system files every 10 seconds for unauthorized changes.

• Automated alerting: Triggers real-time alerts upon anomaly detection, requiring administrator acknowledgment and response.

• Blockchain publishing: Every action taken is digitally signed and published to the BSV blockchain, ensuring auditability and accountability.

• Administrator logging: Includes a signature process that captures response actions via private key and immutably records them on-chain.

Partners: Certihash partnered with SmartLedger to bring blockchain-powered enterprise solutions to market.

IMPLEMENTATION PROCESS

• Pilot phase: Internal deployment and performance testing of Sentinel Node against standard cybersecurity benchmarks.

• Enterprise rollout: Gradual implementation across organizations in critical infrastructure sectors.

• White-glove onboarding: Certihash handles agent software setup and configuration to ensure seamless adoption without disrupting existing security infrastructure.

OUTCOMES & BUSINESS IMPACT

• Detection speed: Reduced average breach detection time from 221 days to under one second.

• System uptime: Maintains 99.999% operational uptime.

• False positives: Lowered rate to 0.001%, drastically minimizing alert fatigue.

• Regulatory compliance: Blockchain-based records support real-time audit readiness.

• Risk mitigation: Businesses can detect, respond, and prove remediation steps immediately—enhancing trust with clients and regulators.

CHALLENGES & MITIGATIONS

Challenge: Enterprise reluctance to overhaul legacy systems.

Mitigation: Sentinel Node is deployed as a non-invasive overlay—requiring no change to existing systems—simplifying adoption and reducing risk.

Challenge: Concerns over blockchain complexity.

Mitigation: Certihash's onboarding service abstracts technical details, ensuring seamless integration without specialized blockchain expertise.

FUTURE VISION

Certihash plans to expand Sentinel Node’s capabilities by integrating:

• AI-driven predictive analytics to anticipate threats before anomalies occur.

• Micropayment-based automated response modules.

• Smart contracts for automated compliance verification.

• Global scale partnerships in sectors such as finance, healthcare, and critical infrastructure.

The team also intends to develop a full suite of cybersecurity tools leveraging BSV, aiming to redefine blockchain-powered enterprise security.
