Network Access Control Security Must Change

Network access control (NAC) is a method of bolstering network security by restricting the availability of network resources to endpoint devices. But NAC was designed to work inside the perimeter – build a perimeter around the internal network, verify users, and once in the door users gain full access to the network or at least a large portion of the network. 

In our changing world – where enterprise technology and employees are increasingly outside the perimeter – NAC is failing.

Goodbye NAC, Hello Software-Defined Perimeter

Overcome NAC limitations with a Software-Defined Perimeter solution that offers an individualized, dynamically adjusted network segments for each user and user session – a segment of one to:

  • Secure enterprise networks with fine-grained control
  • Simplify network security management
  • Reduce operational time and costs across hybrid infrastructure
  • Easily drive consistent compliance policy enforcement across on-premises and cloud-based resources
  • Dramatically simplify user-access audits

Why a Software-Defined Perimeter

A Software-Defined Perimeter is a new network security model that dynamically creates one-to-one network connections between users and the data they access.

A Software-Defined Perimeter solution ensures that all endpoints attempting to access a given infrastructure are authenticated and authorized prior to being able to access any resources on the network. All unauthorized network resources are made inaccessible and invisible to the user. 

How to Overcome NAC Limitations

Why a Software-Defined Perimeter delivers better network security for today’s enterprises

Read the eBook to learn why a Software-Defined Perimeter overcomes these limitations.

This eBook is for security, network, IT architect, operations, infrastructure and GRC professionals who want to protect access to physical, virtual and cloud-based IT systems.

How does a Software-Defined Perimeter work? 

Traditional TCP/IP are not identity centric – it is based on implicit trust and allows anyone to access following on a “connect first, authenticate second” approach. 

A Software-Defined Perimeter is identity-centric and based on zero-trust, so that only authorized users gain access following an “authenticate first, connect second” approach.

Cryptzone Delivers the Market Leading Software-Defined Perimeter: AppGate

AppGate enables organizations to adopt a Software-Defined Perimeter approach for granular security control. AppGate makes the application/server infrastructure effectively “invisible.” It then provides users with access to authorized resources only, verifying user context and attributes — including device posture and identity — before granting access to an application. Once the user logs out, the secure tunnel disappears. When a user’s context changes – such as moving from a corporate to a public network, additional security requirements (such as multi-factor authentication) can be enforced, or access can be denied. All controlled by a simple policy, dynamically applied policy, and imperceptible to the end-user experience.

A Software-Defined Perimeter Architecture

A Software-Defined Perimeter (SDP) architecture is made up of three main components.

Designed for Today’s Hybrid Environments

SDP is designed with today’s dynamic, cloud-centric environments in mind. This lets organizations achieve the agility promised by cloud and virtualized environments without sacrificing security or compliance.
