Network Segmentation

Next-gen firewalls enable network segmentation, dividing the network into smaller, more secure segments to contain potential threats and limit their impact. By creating separate zones or segments based on factors like department, function, or security level, organizations can establish stricter access controls and monitor network traffic more effectively.

This approach reduces the attack surface and prevents threats from spreading across the entire network. For example, if a device in one segment is compromised, the damage can be contained within that segment, minimizing the risk to other parts of the network.

Implementing network segmentation with a next-gen firewall offers several benefits:

• Enhanced security: Each segment can have its own security policies, ensuring that sensitive data and critical systems are isolated and protected.
• Improved compliance: Network segmentation helps organizations meet industry-specific compliance requirements by segregating data and controlling access.

To further illustrate the concept of network segmentation, consider the following scenario:

“Imagine a large organization with multiple departments and thousands of employees. With network segmentation, the company can create separate segments for each department, such as Finance, Human Resources, and IT. This means that employees within each department have access to the resources they need, but their access is restricted to their specific segment. If an attacker manages to compromise a device in the Finance segment, they will not be able to move laterally into other segments, limiting the potential damage and minimizing the impact on the entire network.”

By implementing network segmentation with next-gen firewalls, organizations can significantly enhance their network security posture and protect their critical assets against evolving threats.
