Cisco VPN & Security
New and Used Cisco VPN & Security Devices
With SSL and IPsec virtual private networks (VPNs), businesses can
securely connect remote offices and remote users using cost-effective,
third-party Internet access rather than expensive dedicated WAN links or
long-distance remote dial links.
Organizations can reduce WAN bandwidth costs while increasing
connectivity speeds by using high-bandwidth Internet connectivity, such
as DSL, Ethernet, and cable, and securing it with encrypted IPsec or SSL
VPN tunnels.
VPNs provide the highest possible level of security through encryption
and authentication technologies that protect data traversing the VPN
from unauthorized access. Organizations can take advantage of the
easy-to-provision Internet infrastructure to quickly add new sites or
users, and can dramatically increase the reach of their networks without
significantly expanding infrastructure.
VPNs Extend Security for Remote Users
SSL and IPsec VPNs have become the primary solution for connecting
remote offices, remote users, and business partners, because they:
- Provide secure communications with access rights tailored to
individual users, such as employees, contractors, or partners
- Enhance productivity by extending corporate network and
applications
- Reduce communications costs and increases flexibility
The two types of encrypted VPNs are:
- Site-to-Site IPsec VPN: This alternative to Frame Relay or
leased-line WANs allows businesses to extend network resources to
branch offices, home offices, and business partner sites.
- Remote-Access VPN: This extends almost any data, voice, or video
application to the remote desktop, emulating the main office
desktop. Remote-access VPNs may be deployed using SSL VPN, IPsec or
both, depending on deployment requirements.
