VPN for businesses: important information

VPN play a key role in ensuring the security of Internet activity and organizing secure remote access for employees who need access to corporate networks and resources from anywhere in the world. They bring different types of users together in different places. Their features must be secure, easy to use, and flexible to support different platforms and use cases.

And before setting up a VPN on a corporate network, network architects should review VPN fundamentals, select features that best support their organization's users, and become familiar with best practices for security and secure remote access.

VPN for a company: essence, use cases

VPNs add an additional protocol layer, known as a tunneling protocol, that encrypts and encapsulates network traffic. This process makes traffic opaque to unauthorized users when passing through a VPN and the public Internet. If third parties inspect traffic in transit, they will not be able to access the contents of the packets.

VPNs protect traffic flows between certain users and resources on the Internet from arbitrary analysis by third parties. This is especially important when employees use a VPN to protect work operations, transactions, file transfers and more.

Businesses primarily use VPNs to create a secure private network on top of the public Internet. Common VPN use cases include:

• Remote work: organizations provide VPN for remote employees so that they have secure access to resources and applications of the corporate network.
• Privacy: Users and companies who want to hide their work information and sensitive data from third parties use a VPN to protect their traffic.
• Security: users connecting to the Internet via unsecure networks use VPN to protect their data and prevent information leaks.

Principal components of VPN for organizations

Network administrators encounter various components at different stages of setting up a working VPN, from the client, through the cloud, to the network edge and into corporate networks.

The main components for setting up a VPN include:

• VPN client software. To establish secure remote connections, you need VPN client software. Clients must support the various applications and services that users want to use, such as collaboration tools such as voice and video conferencing.
• VPN infrastructure. Organizations must use special routers and VPN-compatible firewalls that allow legitimate VPN traffic to pass through unhindered while blocking access by unauthorized and unwanted third parties. These VPN devices usually use blocking or filtering techniques for addresses and domain names to enable this process.
• VPN device, hub or server. VPN devices, hubs and servers process and manage incoming VPN traffic, as well as establish and manage VPN sessions and their access to network resources.

Concepts for selecting a corporate VPN strategy

Choosing the appropriate VPN type for a corporate network can present certain difficulties. Network professionals often find themselves at the crossroads between management guidelines and user preferences when choosing a VPN to deploy, which can cause some confusion for staff.

Evaluating VPN client options includes considering a wide range of features and functionality:

• Support for operating systems. For PC users, it's best to have one client that supports all of the operating systems your organization uses. The same applies to mobile operating systems.
• BYOD adoption. BYOD stands for "Bring Your Own Device" (Bring Your Own Device). This is an approach in a work environment where employees use their own personal devices, such as smartphones, tablets, or laptops, to complete work tasks and access corporate resources. If an organization supports BYOD, it should also consider enabling a VPN for mobile devices for both personal and work use. Even on company-provided devices, employees generally welcome this feature.
• Security and encryption. It is important to have broad support for remote access, tunneling, and security or authentication protocols when setting up a VPN. Popular VPN protocol options include SSL/TLS and IPsec, as well as Remote Desktop Protocols or Layer 2 Tunneling Protocol. It is also extremely important to ensure strong encryption.
• Remote support and sharing. The VPN environment should support remote access, remote virtual clients, and the ability to hold joint events and video conferencing.
• Price. Most organizations prefer inexpensive upgrades rather than expensive changes. However, price should not be the only factor when choosing a VPN, as more expensive options may offer greater security and integration.
