Network Segmentation

Segmenting your network can revolutionize your organization's security and performance. By dividing your network into smaller segments, each with their own set of policies, you can control traffic flow and ensure robust security. This architectural approach not only improves monitoring and localizes technical issues but also addresses the vulnerabilities of Operational Technology (OT) networks.

In the past, OT networks relied on an "air gap" for security, but as digital transformation continues, malicious actors are taking advantage of these insecure systems. However, implementing network segmentation can provide a powerful defense against cyber threats. With recent research confirming the rise of ransomware attacks, it's crucial to take action to protect your assets.

Secure your network and protect your critical assets with network segmentation. According to NIST 800-53, dividing your network into isolated subnetworks with unique security controls can help prevent cyberattacks and contain security incidents. Implement specific security controls like access controls, firewalls, IDS/IPS, and network-based authentication mechanisms to support network segmentation. Regularly monitor and audit your controls to ensure they are effectively mitigating security risks. Follow NIST 800-53's recommendations to create a robust security policy.

Protect Critical Assets & Valuable Data with Network Segmentation

Enhance Security and Protect Valuable Data with Network Segmentation

Organizations seeking to address unauthorized access and ransomware cyber threats should strongly consider network segmentation. By implementing this approach in OT environments, you gain a powerful tool to prevent unauthorized traffic flows and protect critical OT assets and valuable data, such as Safety Instrumented Systems (SIS) and trade secret information.

Network segmentation provides both physical and logical security layers to your OT environment. It effectively separates the multiple networks within your OT environment, as well as keeping them isolated from external networks like corporate IT and third-party connections.

Our Network Segmentation service is designed to enhance security by stopping attacks from spreading throughout your OT network and infiltrating vulnerable assets. By effectively segmenting your network, you can prevent malware from spreading and improve overall network performance. This is particularly vital for resource-intensive processes found in manufacturing plants, power generation facilities, and other industrial settings.

Implementing network segmentation in an OT environment can be challenging, considering the potential impact on live production processes. However, with the right tools, experience, technologies, and processes, you can successfully segment and secure your OT environment, safeguarding your operations and valuable assets.

Step up your network security with Zealinx

Enhance Network Security: Network segmentation can provide additional time to respond during a cyber attack, slowing down attackers and minimizing damage. By implementing strong network segmentation, user access to important OT assets can be restricted, protecting against insider and outsider attack. Network segmentation prevents attackers from easily spreading throughout the network, reducing the potential damage caused by a breach. Segmented networks make it easier to protect sensitive OT data, reducing the risk of loss or theft. Network congestion can be reduced and system performance and reliability can be enhanced by segmenting traffic flows and separating critical assets.
