![]() If your end users are VPN split tunneling, where only the traffic that needs to be routed through the VPN tunnel is, then your VPN performance monitoring need only focus on that subset of traffic. Second, the overall end user experience over the VPN needs to be monitored for a variety of contributing factors. IT professionals need to keep a close eye on the number of connected users, and the overall performance of the firewall, which we’ll talk more about below. There may also be licensing restrictions on the number of VPN users connected. The network appliances that are handling the connectivity between the end users and your network, most commonly a firewall, have a limited physical capacity on the number of remote access connections they can support. Monitoring remote access VPNsįor remote access VPNs, there are two ways to approach monitoring, and IT administrators need to be doing both.įirstly, monitoring the overall performance of the tunnel. Just ensure that system security is at the top of your requirement list when evaluating solutions. There’s lots of options out there, so if you don’t yet have a network management system, we’ve put together a list of our top network monitoring tools. In either case, your network management system, like Auvik, should be able to perform the VPN monitoring functions. The tactics used to monitor a VPN will first depend on the type in use, whether it’s a remote access VPN, or a site-to-site VPN. But thanks to ease of setup and the ability to restrict access, SSL VPNs are the more popular of the two options. More commonly, SSL VPN clients also give a full IPsec experience. The SSL VPN portal also only gives users access to specific applications and not the entire network. In the simplest form, an SSL VPN portal, the VPN is browser-based and doesn’t require any software install. SSL, on the other hand, can be much simpler to use. With IPsec, each device then has direct access to the complete central company network. IPsec requires you to install and configure a VPN client on each individual device, and keep the software updated. The two protocols provide secure remote access, but they’re fundamentally different in how they do it. To grant this access, a VPN client uses one of two security protocols to create an encrypted tunnel: IPsec or SSL. The VPN client then creates an encrypted tunnel between the user and a remote network, giving them access to privately hosted applications and resources on the network. In most remote access VPN scenarios, a user will manually start a VPN client and authenticate themselves with a username and password. In this article, let’s focus on remote access VPNs. There are two primary VPN types: site-to-site VPNs (or network-based VPNs), and remote access VPNs (or client-based VPNs). This can be a user’s computer and a remote network, or two independent networks connected together via a secure tunnel. ![]() VPNs (virtual private networks) create an encrypted tunnel between two devices. Here’s what you need to know in order to put out fires from a distance. But bills still need to be paid, customers still need to be contacted, and internal resources like business applications need to be accessed.Īs a result, you may be monitoring and managing an unprecedented number of remote VPN users who, for the most part, are using new and potentially unfamiliar technology. ![]() Since the start of the global pandemic in 2020, most of us can’t go into our offices. Why use a VPN? Well for companies who can’t, or just don’t, host all their information and applications in the public cloud, VPNs are a gateway to business critical resources that employees need to do their jobs when they’re not in the office. Specifically, it’s the process of gaining visibility into the connectivity, throughput, latency and overall performance of a VPN, or virtual private network. VPN monitoring is the application of network performance monitoring to a VPN connection.
