What is a Virtual Private Network (VPN)?
A Virtual Private Network, or VPN, is a tool that allows separate
computers to connect to one another over a network more securely. A VPN
scrambles the connections between two computers so that only the sender
and intended recipient know what is being sent. It is useful for
customers who exchange sensitive data with university computers.
VPN allows customers to use their favorite programs and services much
more securely at UH and from home. VPN account services are provided to
deliver security solutions to customers and administrators, helping to
protect data communications.
The following benefits are provided to UH VPN customers:
- Checking email more securely.
- Connecting to the Internet when using wireless service for on-campus
McAfee VirusScan and accessing some library resources from
- Connecting to any UH service more securely.
UH offers Cisco VPN software (32-bit only) to allow
authenticated, secure access to many UH resources from home or a
wireless connection on campus. This helps confirm a customer's identity
and provide better security to UH systems and services.
For Windows 64-bit users, there is a VPN client built
into the operating system. For information on using the built-in VPN
client, read this Get Help answer: Accessing

VPN at Home
Customers may start their VPN client from home once they have connected
to their Internet Service Provider (ISP). This will create a secure
"tunnel," or separate connection, between your computer and UH,
providing better security.
VPN on Campus
Wireless service allows customers to access the UH network without being
physically connected. When connecting to the wireless network, having
VPN software loaded allows:
- Internet access to be enabled.
- Transmissions between customers and wireless hubs to be scrambled,
or encrypted, to prevent other wireless devices in the area from
- All connections with computers at UH to be more secure.
Wireless customers will be able to access UH computers and network
services such as www.uh.edu
without a VPN client. Internet access is off-limits to wireless
customers without VPN installed, for security reasons.
Cisco VPN is the VPN software used on campus. The University of Houston
does not have a site license for Cisco VPN. A personal license is free
and available when you download the software.
