ExtraHop vs Tenable.sc: What are the differences?

# Introduction
Key differences between ExtraHop and Tenable.sc are outlined below.

1. **Technology Focus**: ExtraHop primarily focuses on real-time network traffic analysis and performance monitoring, offering insights into network, application, and user behavior. In contrast, Tenable.sc emphasizes network vulnerability assessment and compliance management, helping organizations identify and remediate cybersecurity risks.

2. **Deployment Options**: ExtraHop offers both on-premises and cloud-based deployment options, providing flexibility for organizations with varying IT infrastructure needs. On the other hand, Tenable.sc is predominantly deployed on-premises, limiting deployment flexibility for organizations preferring cloud-based solutions.

3. **Data Sources**: ExtraHop collects data through network taps or span ports, enabling passive monitoring of network traffic without introducing additional latency. Tenable.sc relies on active scanning tools to collect vulnerability data, which may introduce some network overhead during scanning processes.

4. **User Interface**: ExtraHop features a user-friendly interface with customizable dashboards for real-time data visualization, enabling users to quickly identify anomalous behavior or performance issues. Tenable.sc interface is more focused on vulnerability management tasks, providing detailed reports and analytics for prioritizing and remedying security vulnerabilities.

5. **Automation Capabilities**: ExtraHop offers robust automation capabilities through integrations with popular IT and security tools, enabling automated responses to network incidents or performance issues. Tenable.sc also supports automation through APIs but is more commonly used for manual vulnerability assessment and remediation processes.

6. **Licensing Model**: ExtraHop typically utilizes consumption-based pricing models, where licensing costs are based on the volume of network data being analyzed. In contrast, Tenable.sc often employs a per-node or per-IP pricing model, which may be more cost-effective for organizations with large, static network infrastructures.

# In Summary, ExtraHop and Tenable.sc differ in technology focus, deployment options, data sources, user interface, automation capabilities, and licensing models.
