Microsegmentation divides networks into controlled segments, limiting the spread of breaches. When TeamViewer was attacked, its segmented network stopped attackers from reaching customer systems.1 According to AlgoSec’s 2026 State of Network Security Report, 90% of organizations have adopted some form of segmentation, but only 35% have implemented microsegmentation broadly across their networks.2

Tufin
Tufin works across different vendors’ devices and platforms, which is useful when you’re managing equipment from multiple manufacturers. This vendor-agnostic approach gives visibility across diverse network components.
- Policy compliance stands out. Tufin flags overly permissive rules and identifies those introducing unnecessary risk. Compliance audits become more manageable. The platform also correlates vulnerabilities with network policies, helping teams address risks proactively.
- API integration with commercial tools and custom solutions is straightforward, letting teams embed Tufin into existing workflows. Managed Service Providers (MSPs) benefit particularly because they handle hundreds of changes across multiple domains.
Key features:
- Network change management: Monitor information about your organization’s network devices by documenting configurations.
- Microsegmentation: Divide a network into granular segments and implement security controls tailored to each segment’s needs.
- Network security policy management: Manage policies to secure firewalls, networks, and assets against unapproved access.
- Firewall orchestration: Execute a centralized security management layer to implement security policies across firewalls.
- Akamai Guardicore integration: Joint solution unifies Akamai Guardicore Segmentation’s workload-level enforcement with Tufin’s centralized policy control plane, providing governance across firewalls, cloud, SASE, and microsegmentation in a single view.3
Choose Tufin for microsegmentation & policy management.
Best practices:
Implement and monitor network microsegments: Users can identify access violations across microsegments by using a corporate matrix, and choose to delete them or mark them as temporary deviations.
Define zero-trust zones: Users can enable zero-trust cloud network access with Tufin.
Create a policy with Tufin:
Users can type a “policy name” and select the following:
- Compliance policy type
- Devices to which the compliance policy will apply
- Recipients to receive alerts when the installed policy conflicts with this compliance policy
Pros

What is microsegmentation?
Microsegmentation is a security approach that divides data based on workload within an organization’s network. Security architects can create protocols that define how all traffic flows north-south and east-west.
Benefits of microsegmentation tools
1. Reduced attack surface
By isolating individual assets, microsegmentation minimizes the risk that an attacker can access multiple resources. Illumio helped Hi-Temp Insulation reduce its attack surface by applying segmentation policies that protected sensitive customer data.
2. Compliance with regulatory standards
Microsegmentation helps companies meet regulatory requirements, such as the GDPR, by ensuring sensitive data is not breached. Cisco enabled Frankfurter Bankgesellschaft, a Zurich-based Swiss private bank, to maintain compliance with data protection laws by securing their cloud environment with detailed segmentation rules.
3. Granular policy control
Microsegmentation provides detailed control over network policies, allowing businesses to define security policies based on users, applications, or workloads. VMware enabled the California Department of Water Resources to implement granular controls for healthcare applications, reducing the risk of data breaches.
4. Enhanced cloud security
In cloud environments, microsegmentation ensures that workloads in different virtual machines or containers are isolated. Illumio used microsegmentation to help a leading hospital network in Brazil secure its cloud infrastructure, preventing unauthorized access to sensitive data.
Network segmentation vs microsegmentation
- Network segmentation enforces traditional castle-to-moat policies that leverage firewall rules at network boundaries
- Microsegmentation creates security zones that can be configured down to the host (computer) level across individual subnets.

Who Should Use Traditional Network Segmentation?
Large enterprises (Fortune 1000, global banks, insurance companies, enterprise SaaS) with complex network security needs. Traditional segmentation doesn’t provide the granular, application-level security these organizations require.
Cloud-native organizations use multiple software, cloud, and SaaS platforms. These face more cloud-related threats and need to secure application workloads at a granular, server-to-server level.
SMEs needing:
- Budget-friendly options
- Overarching infrastructure security without detailed application-level configurations
- Simple networks with basic security needs
- Solutions matching limited technical staff

Who should use traditional network segmentation?
SMEs needing budget-friendly options, overarching infrastructure security without detailed application-level configurations, simple networks with basic security needs, or solutions matching limited technical staff.
Key parameters for choosing between network segmentation and microsegmentation:
- Business scope: Implementing microsegmentation across core business areas can significantly reduce the lateral spread of a ransomware attack. Companies with numerous branches may choose microsegmentation to control intra-network traffic.
- Level of security needed: Organizations with high network security needs, such as Fortune 1000 companies, global banks, or MNCs, may select microsegmentation for finer-grained management and application-level security.
- Network complexity: 35% of IT specialists say that network complexity is an obstacle when segmenting their network. Organizations with less complex networks may use traditional segmentation.
- Financial budget: Microsegmentation integration with a security stack is expected to cost between $40K to $100K on average. Companies with limited budgets and older infrastructure may opt for network segmentation.
- Skilled labor availability: ~40% of IT specialists report a lack of skills and expertise as their main issue when implementing microsegmentation. Companies with limited technical staff may select traditional network segmentation.
