# Example 3: Cybersecurity - Making Vulnerable IoT Defensible

<figure><img src="/files/JT4glC6i83gT8NQ5pPXm" alt=""><figcaption></figcaption></figure>

**Current Challenge:**

**JBS Foods** (largest meat company) hit by ransomware:

* **$11M ransom paid**
* **$575M+ total costs**
* **277 days average time to detect breaches** (IBM 2022)
* **20%+ of food companies** have exploitable vulnerabilities

**Precision Agriculture Alone:**\
IoT devices are notoriously vulnerable entry points for attacks

**Blockchain Enhancement:**\
**CERTIHASH Sentinel Node** methodology:

* Monitors all IoT device and system file changes
* Records hash of every file state on blockchain
* Detects unauthorized changes instantly
* Creates immutable audit trail

**Performance Comparison:**

**Speed Advantage:**

* **720X faster** than mission-critical
* **1,440X faster** than advanced
* **4,032X faster** than standard

**ROI Calculation:**

* Average data breach cost: **$4.24M** ($9M+ in US)
* Early detection reduces costs by **60-80%**
* Blockchain monitoring cost: **<$50K annually**
* Potential savings: **$2.5M-$7M** per prevented/minimized breach

**Why Integration Matters:**\
Precision ag creates attack surfaces. Blockchain provides **detection** that makes those surfaces defensible.
