As organizations increasingly move into the cloud, remote work is now a necessity and common practice. Corporate boundaries have changed and become more fluid.
This means that maintaining networks and connections can be challenging given the limitations of some technologies. There has been a lot of controversy about the availability of the Zero-Trust Network (ZTNA), which replaces the traditional Virtual Private Networks (VPN). While ZTNA is certainly a viable solution for remote or cloud-based environments, VPN technology is not dead.
There are plenty of cloud citizen businesses. They will continue to work in the environment for the foreseeable future. VPN has many useful applications and will have many uses for years.
The first Internet Protocol Security Protocol (IPsec VPN), was created for a specific purpose: to connect people and websites to the internal network. Secure Sockets Layer (SSL VPN) is a different variant. This allows users to connect directly through their browser to the client site.
This narrow application of use cases means that there are inherent limitations in VPN design. It is specially designed to allow planning and implementation of policies before connecting, to control and limit access to each user and each network. This is done in conjunction with firewall rules and network fragmentation.
These limitations are the primary reason VPN technology is obsolete and at the end of its life. It is still a viable solution for many businesses. Many businesses are not fully committed to cloud computing and traditional solutions are in place, so VPN is still a viable option. Simply replacing this principle with a more efficient and effective one to obtain new technologies is expensive and confusing and ineffective.
The reason why ZTNA becomes important is when more cloud-based solutions are implemented, and the environment becomes less logical and therefore requires different controls. A zero-trust model provides access based on identity, regardless of the user’s location and can be granted according to the unique characteristics of the network the user is connected to. For example, if a user is connected to an established network, they may be given a higher level of access than connecting from an open network at an airport or coffee shop. This is not something you can do using a VPN.
ZTNA gives organizations the ability to manage access and set policies on a granular level, making it easier to troubleshoot and more compatible with a seamless network. ZTNA is not the last resort. It is a valuable and conceptual thing that must be part of a great architecture.
ZTNA is part of the Secure Access Service Edge system and is used with other components such as Secure Web Gateway, Cloud Access Security Brokers (CASB) Software-Defined Wide Area Networks (SD-WAN) and Cloud Access Security Brokers (CASB) to provide secure access to networks.
Take complicated matters seriously
As more companies connect to the cloud, it becomes increasingly difficult to maintain a perimeter. This is why technology that can be used in an infinite space is important. ZTNA is the next step in wireless security, but it’s not a magic bullet. The best solution, or a combination of solutions, depends on a variety of factors, including the specifics of communication and environment, and the risk and budget of the company.
The VPN is not gone. It is a viable option, especially regarding the security of older systems. ZTNA becomes important when using cloud or Software as a Service (SaaS) solutions. However, as with all new technologies, a zero-reliance approach is expensive and can impact the business. To ensure that the business is using the best solution (and the most economical) for its needs it is important to work with a technical partner who understands the needs and the reliability of the system and can provide access without danger.
