What is the difference between VPN and zero trust network?

Summary

In this article, I will discuss the difference between VPN and zero trust networks, as well as answer some commonly asked questions related to the topic.

Key Points

1. Zero Trust versus VPN

While VPNs have been widely used for remote access, zero trust networks are a newer concept that aims to provide more secure connectivity. Zero trust networks implement principles that assume there are attackers both inside and outside the network, requiring verification of user and device identities.

2. Do I need a VPN with zero trust?

While VPNs can offer secure remote access, they do not provide the same capabilities as a zero trust network. Zero trust networks go beyond simply granting access and focus on continuously verifying user and device identity to minimize the risk of unauthorized access.

3. What is a zero trust network?

A zero trust network is a security approach that eliminates the concept of trust in traditional network architectures. The philosophy assumes that no users or machines should be automatically trusted, and access is granted based on continuous verification of identity and security.

4. What is another name for zero trust?

Zero trust networks are sometimes referred to as “adaptive authentication” due to the emphasis on continuously verifying user identity and privileges.

5. Why is zero trust better than VPN?

Zero trust networks offer more efficient and secure connectivity compared to VPNs. VPNs route all traffic through a centralized data center, leading to potential delays, whereas zero trust networks are cloud-based and enable quick and efficient connections.

6. Why is VPN better than zero trust?

VPNs can have an advantage over zero trust networks when it comes to latency. VPNs do not require all traffic to be routed through a centralized gateway, resulting in reduced latency and improved performance.

7. What is an example of a zero trust network?

One example of a zero trust policy is multifactor authentication, where users are required to perform multiple authentication methods to access resources. This significantly reduces the risk of unauthorized access.

8. What are the disadvantages of zero trust networks?

Implementing zero trust networks can be complex and expensive, requiring significant changes to network infrastructure and security policies. It can also result in user frustration and reduced productivity due to the need for multiple authentications.

9. What is replacing VPN?

Software-defined WAN (SD-WAN) and Secure Access Service Edge (SASE) are two alternatives to traditional VPNs. SD-WAN provides more efficient routing of encrypted traffic, while SASE combines network security and wide-area networking capabilities.

10. What is the most trusted VPN?

ExpressVPN is a highly regarded VPN service, known for its dedication to privacy and fast speeds. It has consistently received positive reviews and awards.

5. Why is zero trust better than VPN?

Zero trust networks offer more efficient and secure connectivity compared to VPNs. They eliminate the need for routing all traffic through a centralized data center, resulting in quicker and more efficient connections.

6. What is an example of a zero trust network?

One example is the use of multifactor authentication, where users must perform multiple authentication methods to gain access. This significantly reduces the risk of unauthorized access.

7. Why is VPN better than zero trust?

VPNs may have an advantage in terms of latency, as they do not require all traffic to be routed through a centralized gateway. This leads to reduced latency and improved performance.

How is zero trust different from VPN

While VPNs have historically had a place in most network security plans, zero trust is a relatively new concept that aims to fill in the security gaps traditional security approaches miss. An SDP is a network architecture that implements zero-trust principles to provide more secure remote access than VPNs.

Do I need a VPN with zero trust

VPNs are a well-established remote access solution, and many organizations turned to them to support their remote employees. However, while VPNs offer employees secure remote access to the corporate network, they fail to provide crucial capabilities for a zero trust deployment.

What is a zero trust network

The philosophy behind a Zero Trust network assumes that there are attackers both within and outside of the network, so no users or machines should be automatically trusted. Zero Trust verifies user identity and privileges as well as device identity and security.

What is another name for zero trust

This hybrid version of Zero Trust may also be referred to as “Adaptive Authentication.”

Why is Zero Trust better than VPN

That's because VPNs work by routing all traffic through a data center to then be decrypted. But ultimately this process can take time and result in slow-moving protection. Because zero trust is primarily cloud-based, connections are quick and efficient. (Also read: The Best Practices for Managing Cloud Applications.)

Why is VPN better than ZTNA

When it comes to latency as well, ZTNA has an edge over VPN as it does not require all traffic to be routed through a centralized gateway or server. Instead, ZTNA uses distributed gateways that are closer to the user and the resources they are accessing. This reduces latency and improves performance.

What is an example of a zero trust network

One of the most effective Zero Trust policies is multifactor authentication. Requiring that every user perform two or more forms of authentication (such as using a PIN on a known device) every time they sign in significantly decreases the risk that a bad actor with stolen credentials will gain access.

What is the disadvantage of zero trust

Adopting Zero Trust can therefore be a labor intensive process. IT teams need to assess every device and application. Teams must create profiles for every user, with no exceptions. Meticulous planning can also lead to a secondary risk of moving too slowly.

What are the disadvantages of zero trust network

It can be expensive and complex to implement, requiring significant changes to the organization's network infrastructure and security policies. Zero-trust security can also increase the risk of user frustration and reduce productivity, as users may need to authenticate multiple times to access different resources.

What is replacing VPN

Two of the most common choices are software-defined WAN (SD-WAN) and Secure Access Service Edge (SASE). SD-WAN is designed to be a more efficient alternative to the VPN. Instead of implementing point-to-point connectivity, SD-WAN provides optimal routing of encrypted traffic between a network of SD-WAN appliances.

What is the number one trusted VPN

ExpressVPN retained CNET Editors' Choice Award for best overall VPN after its 2023 review. It maintains its position among other virtual private network services thanks to its dedication to privacy and strong speeds.

What is zero trust for dummies

The zero-trust model moves security away from implied trust that is based on the network location of a user or device. Instead, trust is evaluated on a per-transaction basis. With zero trust, your network location or IP address no longer conveys an implication of trust.
