What is ipsec?

In recent decades, remote work has become a central part of America’s business landscape. Being able to complete tasks outside the office leads to greater productivity and flexibility, which is why working remotely has been embraced by more employers each year. For remote work to be effective, employees must have access to their company’s network wherever they travel. A virtual private network (VPN) serves this function. Using a VPN, remote team members can connect directly to the network, performing tasks just as they would while in the office. VPNs also encrypt data to ensure remote access is secure. Clearly, setting up a VPN is a common request from businesses that managed services provider (MSPs) should know how to address.
But there’s more to the story. There are two main types of VPN security protocols, IPsec and SSL, and it’s essential to know the differences between them in order to ensure your customer’s security. In this article, we’ll explain the difference between IPsec and SSL VPN protocols and how to choose the right one to meet your clients’ needs.

What is IPsec?

Internet Protocol Security (IPsec) is the traditional VPN method. Introduced in the 1990s, it is well established, regularly updated, and continues to be widely used. IPsec requires third-party client software on the user’s device to access the VPN—it is not implemented through the web browser. Companies need to purchase client software, install it on each user’s computer, keep it updated, and sometimes pay to maintain their license. This makes IPsec rather complicated to implement and configure.

What is the purpose of IPsec?

The purpose of IPsec is to give the remote computer direct access to the central network, making it a full member. Remote users have access to any file storage locations, programs, printers, and backups, exactly as if they were in the office. IPsec is therefore a robust system that gives users whatever resources they need, wherever they are located.
