Enforce Segmentation with Visibility, Automation, and Compliance

Network segmentation is the practice of dividing a computer network into smaller, segmented networks or subnets to improve network security and performance. By creating separate security zones, organizations control network traffic flows, apply targeted security policies, and reduce the attack surface. Segmentation limits unauthorized access, contains malware outbreaks, and helps protect sensitive data against cyber threats and data breaches.

Tufin helps organizations design and enforce segmentation strategies across on-premises, cloud environments, and hybrid network infrastructure, ensuring compliance with frameworks like PCI DSS.

• Firewalls and access control lists enforce rules between parts of the network
• VLANs and subnets separate network devices and workloads into logical groups, called segments
• Routers and SDN direct traffic flows between segments
• Authentication and permissions restrict network access to specific zones

These measures prevent attackers from moving laterally across the internal network, reducing the chance that a cyberattack on one system spreads to the entire network.

• Network segmentation creates boundaries between large groups of workloads, subnets, or data center resources. It improves network performance, reduces network congestion, and enhances cybersecurity by controlling traffic flows at the network perimeter.
• Microsegmentation operates at a finer level, controlling traffic between individual endpoints, apps, or specific workloads within a segmented network. It is often used in Zero Trust security strategies to stop east-west lateral movement.

Both approaches work together: segmentation sets the foundation, while microsegmentation enforces least privilege at a more granular scale.

• Firewalls and access control rules apply restrictions between security zones
• Segmentation policies and automation define how permissions and traffic flows are applied
• Network administrators configure routers, VLANs, and subnets to separate parts of the network
• Continuous monitoring validates security posture and detects unauthorized access or policy drift

Tufin automates segmentation enforcement by aligning security policies with network architecture, ensuring consistent application across on-premises, cloud environments, and hybrid networks.

• Reduce the attack surface by limiting how much of the internal network is exposed
• Contain threats by isolating malware infections or cyberattacks to a single security zone
• Protect sensitive data and reduce the risk of data breaches
• Support compliance requirements for compliance frameworks like PCI DSS by segregating credit card data and related workloads
• Improve network performance by minimizing network congestion and optimizing traffic flows

Zero Trust security is based on the principle of never trust, always verify, and network segmentation is a key enabler. By dividing the network infrastructure into segmented networks, organizations enforce least privilege, strengthen access policies, and reduce lateral movement. When combined with microsegmentation and continuous authentication, segmentation becomes part of a broader Zero Trust strategy to secure cloud environments, SaaS apps, and on-premises systems.

• Improved security by preventing unauthorized access and reducing the impact of cyberattacks
• Compliance support through meeting regulatory mandates, such as PCI DSS
• Operational resilience by containing malware outbreaks and protecting the entire network
• Performance optimization by reducing network congestion
• Stronger security posture with enforced controls and reduced vulnerabilities

Tufin delivers the benefits of network segmentation by providing centralized visibility and automated enforcement of segmentation policies, ensuring consistency across large, complex, hybrid environments.

• Firewalls that enforce security policies between security zones
• Routers and switches that manage traffic flows across subnets and VLANs
• Access control lists and authentication mechanisms that restrict network access
• SDN and automation platforms that streamline policy enforcement in cloud environments and hybrid networks
• Continuous monitoring solutions that track network traffic and maintain compliance with segmentation policies

Tufin provides the orchestration layer for these tools, automating segmentation policies and helping network administrators maintain consistent enforcement across network devices, cloud platforms, and on-premises infrastructure.
