The challenge
Your organization faces the challenge of securing a complex network with a growing number of managed and unmanaged devices, including IoT and BYOD. The lack of visibility into these devices creates security gaps that can be exploited by attackers, leading to data breaches and compliance violations. Traditional security models struggle to adapt to hybrid work environments, and manual processes are time-consuming and error-prone. You need a solution that automates network access control, provides comprehensive visibility, and enforces consistent security policies across your entire network.

The solution
NAC addresses your unique challenges through modern solutions and key capabilities.
Comprehensive visibility and fingerprinting
Discover and identify every device on the network without requiring an agent, categorizing them by brand, model, and OS version with high accuracy.
Dynamic segmentation and VLAN steering
Automatically assign users to specific network segments based on their identity and device posture, preventing lateral movement of threats.
Automated posture assessment
Verify that devices meet security requirements (e.g., disk encryption, updated patches) before granting network access.
Integrated guest and BYOD management
Provide a self-service portal for visitors and contractors, ensuring they remain isolated from the core corporate network.
Vendor-agnostic enforcement
Enforce consistent security policies across a multi-vendor network environment, regardless of the switch, router, or access point brand.
AI-powered threat detection
Leverage machine learning to identify anomalous behavior and isolate threats in real-time, such as unauthorized devices attempting to access sensitive resources.

How to evaluate NAC
1
Deployment flexibility
Evaluate whether the solution offers cloud-native, on-premises, or hybrid deployment options to align with your organization's infrastructure strategy.
2
Interoperability and ecosystem integration
Ensure the NAC solution integrates natively with existing identity providers (IdP), endpoint detection and response (EDR) tools, and SIEM platforms.
3
Scalability and performance
Verify the system can handle peak connection times without introducing latency or authentication timeouts.
4
Compliance templates
Prioritize vendors that provide pre-built reporting templates for industry-specific regulations to reduce the burden on compliance officers.
