The Top 6 Enterprise VPN Solutions to Use in 2024

Ensuring secure remote connections to company networks and resources is one of the most significant challenges facing enterprise owners. This concern has been amplified by the findings of a recent IBM® report, which estimates the average cost of a data breach in 2023 to be $4.45 million.

As a result, the deployment of enterprise-level virtual private network (VPN) solutions has become a critical priority for many businesses, particularly with the increase in remote employees. These security solutions are essential for protecting sensitive data and maintaining the integrity of corporate networks.

What are the benefits of using an enterprise VPN?

Enterprise VPN solutions serve as a secure gateway, connecting employees to their corporate networks from any location. They come equipped with features like management via command line interface (CLI), RESTCONF application programming interface (API), graphical user interface (GUI), or IT automation platforms like Ansible®, SaltStack®, Puppet®, or Chef.

They are also equipped with support of multiple VPN protocols, advanced logging and monitoring, virtual routing and forwarding (VRF), and more.

These features enhance the management and security of enterprise networks, safeguarding against unauthorized access and potential breaches.

How do VPNs work?

The core function of a VPN is to create a private network over a public internet connection, offering the VPN client anonymity, online privacy, and protection from hackers. It effectively hides the user's IP address, reducing their digital footprint, and secures and encrypts their connections.

This can be visualized as a secret, encrypted tunnel between the user's device and the internet, or between two VPN endpoints, where only the user and the intended recipient can view the data being transmitted.

This level of cybersecurity is crucial for large enterprises as well as small businesses, especially those with employees who frequently use public Wi-Fi networks for online activities or remote work. Enterprise VPNs, also known as business VPNs, not only encrypt connections to prevent unauthorized access but also enable administrators to establish granular access controls, further enhancing network security.

In this article, we will discuss which enterprise VPN solutions are considered top-tier for businesses in 2024. We will examine the key features of these solutions, including user experience, VPN connection type, user data protection, and more to help you identify the top VPN solutions on the market.

Enterprise VPN FAQ

Here are answers to common questions about enterprise VPNs. If you don’t see an answer to your question here, please see our main FAQ or contact us.

What should you be aware of when using a VPN?

When using a VPN, it's crucial to consider the strength of the security protocols in place, as they are fundamental in protecting your data and network traffic. For example, protocols like WireGuard and IPsec, as used by TNSR software, are known for their robust encryption.

Another consideration is the impact of VPNs on network performance. While they enhance security, they can sometimes slow down network speeds.

It's also important to be mindful of legal and compliance issues, especially if operating across different countries, as VPN usage and data privacy laws can vary. The server locations can influence both performance and jurisdictional concerns, so selecting a VPN with strategically located servers is beneficial.

Additionally, understanding the VPN provider's logging policies is essential, as different businesses have varying needs for privacy. Features such as access controls and network segmentation, like the VRF offered by TNSR, are important for managing and safeguarding sensitive corporate data.

Finally, ensure that the VPN is compatible with the devices and platforms your business uses, as not all VPN solutions support all types of devices.

How do I choose the best VPN solution for my business?

Choosing the best VPN solution for your business involves assessing your specific needs, such as the number of users, the type of data handled, and your security requirements. It is important to compare the security features of different VPNs, focusing on strong encryption protocols and additional security measures like firewalls.

The ease of management and integration with existing IT infrastructure is another crucial factor. Solutions offering various management interfaces provide greater flexibility. The performance and reliability of the VPN are also key considerations, as high performance without significant speed loss is ideal.

Customer support and the quality of documentation are indicative of the reliability and user-friendliness of the VPN solution.

Cost is always a significant factor, so it's important to consider how the VPN fits into your IT budget, keeping an eye out for transparent pricing structures. Researching the reputation of the VPN service provider can give insights into their reliability and customer satisfaction.

Lastly, utilizing trial periods or demos can be a practical way to test how well a VPN solution fits into your environment before making a long-term commitment.

Is VPN outdated?

While VPN is a technology that’s been utilized for quite some time, it is also a tried and tested technology. It’s rare to take revolutionary jumps in tech. Rather, concepts build and grow. Much like tape to spinning disk to solid state.

VPN, or point to point encryption, will most likely never go away. However, the way in which it’s utilized will change over time. Zero trust network architecture (ZTA) will utilize VPN in a more secure manner, but will still leverage the technology. For more information on ZTA, refer to the following section.

So, is VPN outdated? Like any technology…yes and no. As long as you are using modern encryption, patching your systems, and leveraging new technologies to assist with security, VPN is a crucial aspect of any security posture.

What technologies are replacing VPN?

Zero trust network architecture, or ZTA, is the evolution of VPN and firewall. ZTA will leverage VPN technology and expand on it to enable the concept of mesh VPN. This is where an edge device will create a VPN directly to the targeted application, or the closest router that can terminate that VPN before that application.

This VPN will bypass every other form of security along the way, such as firewalls, IPS/IDS, etc. As this is a secure tunnel, and can only be created if the user has permission to create the tunnel in the first place. They will authenticate in a similar manner to today.

However, this does not mean that the user will gain access to the application itself, just to the “front door.” The same application boundary will still exist. Just like if you have someone’s home address, it doesn’t mean you can just walk into their house. They still need to let you in.

The application will then check the credentials of the user, and grant access or deny. Either way, that conversation will happen over the “single use VPN,” and once that communication is done, the VPN will then be torn down.

Mesh VPN is essentially many point-to-point conversations, only with systems that the user is allowed to establish communication with. How is this zero trust? By establishing many point-to-point VPNs, and then authenticating with the systems themselves, the user is not allowed to gain access to the systems that are also on the same subnet/VPC. They can only see the application to which they are allowed to communicate.

After they knock on the door, the application will authenticate the user for the level of access they have to the application. Today, once a VPN is established to a network, they have access to anything within the network. That permission doesn’t exist in ZTA.

What is the difference between personal VPN and enterprise VPN?

Personal VPNs are intended for individual use, emphasizing online privacy, internet security, and access to restricted content. They offer user-friendly interfaces, simple setup, and features like server selection and ad-blocking. However, they may not meet complex organizational security requirements.

In contrast, enterprise VPNs cater to organizational needs, providing employees secure access to company resources. These VPNs come with advanced security features, including end-to-end encryption and robust authentication methods, and they are equipped for network administration, regulatory compliance, and integration with enterprise tools.

They are designed to support a large and globally distributed workforce, making them more suitable for business environments than personal VPNs, which prioritize ease of use and privacy for individual users.

Which type of VPN is the preferred choice?

The preferred type of VPN largely hinges on the user's specific requirements. Individuals prioritizing online privacy, desiring secure internet connections (especially in public spaces), or wishing to access region-restricted content typically find personal VPNs more suitable. These VPNs are user-friendly and geared toward protecting individual privacy and bypassing geographical restrictions.

On the other hand, businesses and organizations with a focus on securing internal networks, managing access for on-premises employees and remote workers, and adhering to compliance standards are better served by enterprise VPNs.

These offer more robust security features, administrative controls, secure remote access for employees’ laptops and other mobile devices, and the ability to handle a large number of users, making them ideal for organizational use. Therefore, the choice between a personal and an enterprise VPN is dictated by whether the user is an individual seeking privacy or an organization aiming to safeguard corporate data and regulate network access.

What is the strongest type of VPN?

The concept of the "strongest" VPN is multifaceted, depending largely on factors like encryption standards, protocols used, privacy policies, and additional security features. A VPN employing AES-256 encryption is generally considered robust, as this is a widely recognized high-security standard.

Protocols play a significant role too, with options like OpenVPN and WireGuard known for their optimal balance of speed and security, with WireGuard especially noted for its modern approach.

Privacy-wise, VPNs adhering to a strict no-logs policy are stronger, ensuring user activity isn't recorded. Enhanced security features such as a kill switch, leak protection, and multi-factor authentication further fortify a VPN's strength. The security of the VPN servers themselves, both physically and virtually, is equally crucial. Moreover, a VPN's jurisdiction can affect its privacy strength due to varying international data retention laws.

Therefore, the strongest VPN depends on individual needs, whether prioritizing privacy, speed, or a combination of factors, and it's vital to select a service that excels in areas most pertinent to these specific requirements.
