Virtual private networks, or VPNs, create a private network across a public internet connection. They give you anonymity and privacy by hiding your internet protocol (IP) address, which reduces your digital footprint, and by securing and encrypting your connections. Think of the VPN as a secret tunnel between your device and the internet; nobody can see what you’re doing inside the tunnel except you and the person on the other end that you’re sending data to – not even your internet service provider. This means that users can send and receive information as securely as if they were directly connected to a private network. But why does your business need a VPN?
When you surf the internet on an unsecured Wi-Fi network, anyone else using the same network can tap into what you’re doing and access your browsing habits and private information. Firstly, by encrypting your connections, a VPN secures your online activity against anyone trying to access it without your permission. Secondly, a private connection improves security across private networks when users are connecting via a public or insecure Wi-Fi router. This is a particularly useful feature for organizations with employees working remotely, either from home or in a role that requires them to travel. Thirdly, VPNs should allow admins to set up granular access controls that restrict users from accessing areas of the network that they don’t need to. Some VPNs do this through internal gated networks, and some deploy it at an application level. A powerful VPN should also come with built-in firewalls to protect against viruses, hacks and other threats.
Large enterprises require a high level of security, sometimes for thousands of users at once. It’s important that a business VPN is able to cater for this demand, as well as give the organization the tools it needs to be able to deploy and manage their VPN, and integrate it with other security resources.
In this article, we’ll explore the top ten VPNs for business, which are designed specifically to protect corporate web connections. Each of these offers different features, including varied device compatibility, scalability, central management and activity management. We’ll give you some background information on the provider and the key features of each solution, as well as the type of customer that they are most suitable for.
The Top 10 VPNs For Business includes
- Cisco AnyConnect | Citrix Gateway | Fortinet | Google | NordVPN | Palo Alto | Perimeter 81 | Pulse Secure | SonicWall | ZScaler
Secure, scalable VPN that offers protection for Android and iOS devices as well as desktops
Cisco is a market leader in enabling and securing remote ways of working. Their products range from digital conferencing tools to internet access security, always ensuring that organizations’ communications are protected. AnyConnect is Cisco’s policy-driven VPN tool, designed to secure remote workers’ network access across wired, wireless and VPN connections. The solution provides secure access to the network from any device, at any time, from any location and offers complete visibility as to who is accessing an organization’s network through a single management agent.
AnyConnect uses the IKEv2 and SSL protocols to support a highly secure internet connection. All users are authenticated using multi-factor authentication (MFA) before connecting, to ensure only those with permission are granted access. The use of MFA means that hackers can’t tap into the connection, even if they know the user’s password. All data traffic is encrypted so that if the connection is intercepted, the data traffic will be unreadable. With AnyConnect Secure Mobility Client, organizations can also protect Android and iOS devices, which provides complete protection until the device is turned off. Admins are granted complete visibility across the extended enterprise, including mobile devices, as to who is accessing the network and from which device. If support is required, Cisco offers a 24/7 tech support for application managers.
AnyConnect delivers software updates automatically to make sure that users always receive the most efficient and effective protection possible. It integrates well with other Cisco solutions, so organizations can use it as a stand-alone product or as a part of a wider security stack. For this reason, we recommend Cisco AnyConnect as a strong, scalable VPN solution for all large enterprises, but particularly those with an interest in investing in other Cisco products.

Google Cloud VPN
Fast, secure VPN service with automatic maintenance and simple configuration and deployment options
Google produces a number of cloud security products under their Google Cloud brand to help keep organizations’ critical assets secure and their processes compliant. Their solutions are designed to cover all aspects of security, from the overall network architecture down to the granular protection of users and endpoints. Cloud VPN is Google’s VPN service, offering a fast, secure connection between remote users and their organization’s wider network.
Google offers two types of Cloud VPN: HA (high availability) VPN and Classic VPN. Both of these connect a user to their network through an IPsec connection. Google’s Cloud VPNs encrypt traffic at one end, then decrypt it when it reaches its destination. This means that all information sent is kept secure and private, so that not even the service provider can read the user’s data. The HA VPN offers a service-level agreement (SLA) of 99.99% service availability; the Classic VPN offers an SLA of 99.9%. Customers praise the Cloud VPNs user-friendly interface, though it’s important to note that the HA VPN runs across two separate interfaces. Both VPNs use external IP addresses to protect the user’s identity and location when browsing. The HA VPN chooses IP addresses from a pool, but an admin must create external IPs if running the Classic VPN.
Google regularly performs automatic maintenance on their Cloud VPN services, ensuring that users always receive the highest possible level of protection. Both solutions are easy to set up, and Google provides in-depth support so that even those with little technical expertise can configure networking policies with ease. This is a strong solution for organizations looking for a secure VPN that’s simple to configure and easy to manage post-deployment.

ZScaler Private Access
Secure, segmented access to all apps from all devices that runs on lightweight software to reduce strain on system resources
ZScaler is a market-leading vendor in cloud-based web security that scales to grow with the client’s organization. ZScaler Private Access (ZPA) is their zero-trust cloud-based solution that provides a seamless, secure connection between remote devices and private applications running on the public cloud or within a data center. It ensures that applications are never exposed to the internet, so that they’re completely inaccessible to unauthorized users. ZPA supports both managed and unmanaged devices, and secures the connection to any private application, not just web apps.
ZScaler Private Access is built on a zero-trust network access (ZTNA) foundation, which means that apps are connected to outbound to authorized users, rather than the network being extended as with some traditional VPNs. This means that IP addresses are always hidden and DDoS is impossible. Once authorized, users can access specific private apps without having to access the overall network, which reduces the risk of the lateral spread of ransomware. From the ZPA management portal admins have granular control over creating and defining policy names, selecting the applications that each policy is associated with, and configuring permissions for users and user groups down to individual application and user level. Additionally, ZPA uses the same ZScaler Client Connector app as their internet access solution, ZIA, to ensure that browser access is available for web apps.
ZPA’s solution takes a user- and application-centric approach to access security. The segmented connections between applications and user devices makes this solution particularly good at reducing lateral movement. Because it’s cloud-based, ZPA is quick to deploy and extremely scalable, so organizations don’t have to worry about using external hardware to upgrade their protection as they grow. We recommend ZScaler Private Access as a strong secure access solution for enterprises looking for seamless remote access for their employees that scales easily and helps to reduce the threat of ransomware attacks.
