The Benefits and Challenges of Using VPNs
Virtual Private Networks (VPNs) are a cost-effective and secure alternative for WAN communications between corporate and government offices and employees. Increasingly, IT departments are migrating remote locations to IP-based or MPLS-based VPNs in order to:
- lower WAN costs
- extend scalability
- improve reliability
- secure networked data
However, the VPN tunneling and encryption that protects the packets during transport over the public network also obscures the details required for troubleshooting and traffic engineering networks.
The NetScout Solution and Site Monitoring
NetScout's NetScout Solution monitors application traffic flows in VPN network environments and display real-time and historical views in a common format. By monitoring remote sites using NetScout's unique Site Monitoring feature the nGenius® Performance Management System delivers real-time analysis of the traffic transported over VPN WAN before tunnels and encryption obscure critical details. Site Monitoring overcomes the complexity involved in VPNs by letting IT staff instrument the LAN side of the network with nGenius Probes to allow monitoring traffic from the remote-site WAN perspective.
