It's Time to Replace your VPN

The network perimeter is disappearing.

The rise of new types of devices and the push to cloud environments long ago dissolved the strong network perimeter. Viewing the corporate network as a strongly-protected island accessible via a VPN is simply not valid anymore. Modern environments need a modern solution like CrossLink ZTNA.

VPN grants users more access than they should.

VPNs come from a time when everything "inside" the network perimeter was blindly trusted. Once in, the user had open access. In contrast, the ZTNA "least privilege" model grants users only the access they were explicitly given, which is especially critical with the rise of working from home on user-owned devices today.

VPN does not scale easily.

Scalability in a VPN means having to replace a piece of hardware on the network. With the COVID-19 pandemic and explosion of working from home, many enterprises found themselves waiting months for a new VPN concentrator to meet the increased demand. In contrast, a ZTNA cloud service like CrossLink is designed for agility and flexibility, scaling with the click of a button.

"By 2023, 60% of enterprises will phase out most of their remote access virtual private networks (VPNs) in favor of ZTNA."

Why CrossLink for VPN Replacement

...

All Applications

CrossLink is a true drop-in replacement for VPN because it supports all applications—both legacy and modern. ZTNA vendors that only support web-based applications or use DNS-based routing, simply cannot replace a VPN; instead, they will require either a costly migration or a parallel VPN infrastructure to support legacy or IP-based applications.

All Users

CrossLink supports all disparate user types—employees, third-party, managed, unmanaged, mobile, IoT, etc.—in a single, unified solution, with a seamless user experience regardless of endpoint device. Vendors that only support one type of user, or assume that all users are the same, will require the deployment of multiple, costly point solutions to handle all use cases.

All Devices

CrossLink ensures that only healthy devices are able to access enterprise resources and applications, with consistent health policies across all types of devices. The rise of "work from home" and BYOD has resulted in ever-increasing numbers of untrusted devices connecting to enterprise resources and applications. Vendors that do not fully attest devices both before and during the access lifecycle open up channels for attack into the enterprise network.

Simplified Management with Automatic Policy Discovery

CrossLink Policy Discovery Engine automatically monitors and learns the access requirements of different groups, simplifying the transition from VPN to the zero-trust model. The Policy Discovery Engine leverages machine learning to dynamically construct access control profiles, greatly reducing costs by simplifying the process of moving from "open-access" VPN policies to a "zero-trust" model.

Not All ZTNA Solutions are Created Equal

ZTNA products that fail to address the following criteria can simply never be drop-in replacements for VPN:

 
CrossLink
Other Vendors
Support for all applications and protocols, including IP-based protocols, out-of-the-box, avoiding the need for running a costly parallel VPN infrastructure.
?
Support for legacy applications out-of-the-box, avoiding the need for expensive migrations of these applications.
?
Support for all types of users—from managed employees to unmanaged third-party to IoT—under a single deployment, avoiding the need for multiple point solutions.
?
Fine-grained device health attestation both before and during the entire access lifecycle, ensuring dangerous devices never have access to the enterprise network.
?
Tools to simplify the transition process from an "open-access" model of VPN to the "zero-trust" model of ZTNA, greatly reducing the cost and risk of adoption.
