Explainer: What is Sentinel Node?

Certihash’s Sentinel Node is a next-generation cybersecurity detection assurance tool.

In today’s vast digital landscape, most data files continue to exist in a legacy environment which makes them vulnerable to bad actors and other potential security flaws. SmartLedger is dedicated to solving these and other problems through its custom-made blockchain solutions.

SmartLedger developed the Certihash suite specifically for enterprise clients, offering them a solution to mitigate the risks of data breaches. The initial module released within Certihash is Sentinel Node, which provides real-time event notifications for network activities. This comprehensive toolset leverages the BSV blockchain to ensure records’ confidentiality, integrity, and availability, making them publicly accessible on a permissionless blockchain.

What is Sentinel Node?

Certihash’s Sentinel Node is a next-generation cybersecurity detection assurance tool which provides instant file integrity and change monitoring of network anomalies and events, mitigating the overall time to identify a data breach.

It does this by utilising the BSV blockchain to limit the need to transfer sensitive log data to a third party, allowing for exponentially faster detection and alert times.

Sentinel Node creates a chain of hashes for each file entry, protecting the data integrity of all data on the network. These hashes are placed on the public blockchain ledger, ensuring transparency and security.

When a cybercriminal attempts to cover their tracks, Sentinel Node will discover the hash break immediately and alert the system administrator.

Better and faster than the rest at breach detection

While most Security Information and Event Management (SIEM) tools claim to provide ‘real-time’ detection, in reality, most have a window of more than two hours between log capture transfer, analysis and alerting. By comparison, SmartLedger estimates that Sentinel Node is:

  • x720 times faster at critical log detection;
  • x1.400 times faster at advanced log detection;
  • x4,032 times faster at standard log detection.

Other benefits of Sentinel Node include:

  • Sensitive data always stays in-house;
  • Faster file integrity monitoring;
  • Instant alert upon change detection;
  • Permanent attestation of alert records;
  • Data is recorded in perpetuity;
  • It provides actionable cybersecurity intelligence.

BSV Blockchain Association – a proud partner of SmartLedger

BSV Blockchain Association is pleased to partner with SmartLedger on a series of explainer videos about its Certihash and Sentinel Node products.

BSV Blockchain Association is a non-profit association (Verein) based in Switzerland and a global industry organisation which advances the BSV blockchain (BSV). It brings together enterprises, start-up ventures, developers, merchants, exchanges, service providers, blockchain transaction processors (miners), and others in the BSV ecosystem.

The Association supports BSV as the original Bitcoin, with a stable protocol and massive scaling roadmap to becoming the world’s new money and global blockchain for enterprise. The organisation seeks to build a regulation-friendly ecosystem that fosters lawful conduct while encouraging digital currency and blockchain innovation.
