What is VPN monitoring?

WGlobalization has completely changed the way enterprises are run today. Global conglomerates typically have multiple offices at varied locations and a highly dynamic group of employees. This typically leads to a plethora of complications in a company’s network infrastructure, especially when it comes to sharing files within the organization, across different branches, and with remote employees.

This is where a virtual private network (VPN) comes into play. VPNs allow enterprises to create a secure connection to another network over the internet. Enterprises typically deploy VPNs in the following ways:

  • Site-to-site VPN: Connects entire networks to each other via a dedicated VPN tunnel. For example, connecting a branch office network to a company headquarters network.
  • Remote access VPN: Connects individual hosts to private networks. For example, travelers, teleworkers, and mobile users who need to access their company's internal network securely over the internet.

Merely deploying a VPN alone does not guarantee smooth IT operations. You need to constantly monitor VPN connections (VPN Tunnel Monitoring) for possible bandwidth constraints and security threats. With a VPN monitoring tool, you can fetch VPN logs from your firewall and generate relevant traffic and security reports.

Firewall Analyzer is VPN monitoring software that tracks VPN connections for both remote host VPNs (PPTP, L2TP, and IPsec) and site-to-site VPNs from vendors like Cisco, SonicWall, WatchGuard, and NetScreen. As a VPN tunnel monitoring tool, Firewall Analyzer generates VPN reports that help with:

1. VPN bandwidth management: Monitor VPN activity and usage, identify high bandwidth consumption, track destination URLs, and block unwanted traffic.
