# Watch: Certihash / Sentinel Node (Case Study) {% embed url="" %} 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. ### Certihash Node Overview Sentinel Node, advanced cybersecurity using blockchain technology for near-instant breach detection and response. Powered by Sentinel Node, the Certihash solution **reduces breach detection time from 287 days to under 1 minute.** *** ### **Learn More** [**Read the case study**](https://hub.bsvblockchain.org/case-study-library/cybersescurity/sentinel-node-certihash-by-smartledger) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
