Graynet applications use port agility and encryption to bypass corporate security controls.

Graynet poses three main issues:

1. Security: Graynets may expose loopholes in a network. These can be compromised by malware or viruses propagated in the end-user systems.
2. Privacy: Corporate information can be leaked via graynet.
3. Compliance: Employees may use or misuse the unmanaged communication networks created by graynet.

The most pupular graynet applications include:

• Instant messaging
• Web browsing
• Peer-to-peer file transfer
• Web conferencing
• Blogging and Web mail
• Adware/spyware
