ExtraHop vs Snort: What are the differences?

Key Differences between ExtraHop and Snort

ExtraHop and Snort are both network security tools used to monitor and detect potential cyber threats. However, there are several key differences between the two:

1. Deployment: ExtraHop is a passive network monitoring tool that is deployed as an appliance within the network. It monitors network traffic in real-time without generating any additional network traffic or requiring specific network configuration. On the other hand, Snort is an intrusion detection and prevention system (IDPS) that needs to be deployed on a separate server or device. It analyzes network traffic by inspecting packets and can actively block suspicious or malicious traffic.

2. Detection Methods: ExtraHop uses wire data analytics to analyze network packets and extract valuable insights from the data. It passively collects and analyzes network traffic, providing visibility into application performance, user behavior, and security threats. Snort, on the other hand, uses signature-based detection techniques, which involve comparing network traffic against a database of known attack patterns or signatures. It can also perform protocol analysis and anomaly-based detection.

3. Scalability: ExtraHop is designed to scale horizontally, meaning multiple appliances can be deployed to handle increasing network traffic. It can also analyze encrypted traffic and supports cloud deployments. Snort, on the other hand, has certain limitations in terms of scalability. It relies on the server or device it is deployed on, and as network traffic increases, it may require additional resources or multiple instances to handle the load.

4. Ease of Use: ExtraHop is known for its user-friendly interface and intuitive dashboards. It provides visualizations and detailed analytics that can be easily understood by both security analysts and network administrators. Snort, on the other hand, has a steeper learning curve and requires knowledge of configuring and managing rules and signatures for effective threat detection. It may require more technical expertise to fully utilize its capabilities.

5. Integration: ExtraHop offers seamless integration with other security tools and platforms through its open API and integrations with popular SIEM (Security Information and Event Management) systems. It can also integrate with threat intelligence feeds to enhance its detection capabilities. Snort also supports integration with other security tools but may require additional configuration and customization to achieve seamless integration.

6. Commercial Support: ExtraHop offers commercial support options, including technical support, training, and professional services, which can be valuable for organizations that require assistance or expertise in deploying and managing the tool. Snort, being an open-source tool, relies on community support, although there are commercial offerings available that provide support and additional features.

In summary, ExtraHop is a passive network monitoring tool deployed as an appliance, while Snort is an IDPS that needs to be deployed separately. ExtraHop uses wire data analytics, scales horizontally, and focuses on ease of use and integration. Snort uses signature-based detection, requires more technical expertise, and has limitations in scalability. ExtraHop also offers commercial support options, while Snort relies on community support.
