Enterprise network designs often include virtual private networks, due to their ability to connect users and networks to each other securely. While newer technologies offer network teams alternatives for network security, the advantages of VPNs continue to make them an integral part of enterprise networking.

Benefits of VPNs

Network teams can choose from a range of technologies to provide secure access and encrypt data. But the ease and uniqueness of VPNs make them a staple for secure remote access strategies. Below are some common advantages of VPN technology.

encrypt datum and anonymize IP address

Connecting from a public hotspot exposes a user’s data. Using VPN software installed on a laptop, phone or tablet means data is encrypted from the device to the destination site.

Another benefit of a VPN is it can anonymize the connecting internet address to the accessed website, so the connection appears to come from a different IP address for each connection. Changing an address makes it more difficult to track the use of a site.

A VPN connects various authorized users to corporate resources.

Pros and cons of VPN encryption technologies

A VPN can use several different encryption technologies, each with its advantages and disadvantages.

L2TP / IPsec

Layer 2 Tunneling Protocol/IPsec (L2TP / IPsec) uses a Layer 2 tunneling protocol plus IPsec to provide encryption. It is available on nearly every type of OS and device.

Advantages of L2TP / IPsec include the following:

extremely secure and stable with easy setup .
Higher efficiency than OpenVPN.
