# Watch: Certihash / Sentinel Node (Case Study)

{% embed url="<https://youtu.be/a3OdA6qCwlg>" %}

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.**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hub.bsvblockchain.org/higher-learning/bsv-academy/introduction-to-blockchain-technology/the-fundamentals-of-blockchain-and-web-3-technology/watch-certihash-sentinel-node-case-study.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
