BorderManager continues to be an effective perimeter solution for company data security.

Security is Getting Harder

Security threats these days are multiplying quickly. Viruses propagating faster, and the use of spam is exploding. There are new paths for hackers, including IM, chat, and P2P networking.

The threats are also becoming more complex. "Blended threats" propagate across multiple paths, while application-level attacks exploit weaknesses in popular applications.

Additionally, there is now greater scrutiny of security coming from legislation, continuing audits, and top-management awareness.

Problems Solved at the Perimeter

Here are some common security problems along with their perimeter solutions:

Problem: Employee productivity is impacted by free use of the public Internet.
Solution: Use of proxy

Problem: There is a liability exposure from people surfing to inappropriate sites.
Solution: Proxy

Problem: Content from the public Internet is a security risk
Solution: Proxy

Problem: There is increasing utilization of finite bandwidth
Solution: Proxy

Problem: Secure, remote access must be provided to non-Web applications
Solution: VPN

Problem: Virus replication occurs because of inappropriate downloads
Solution: Secure Web Subscription

Problem: SPAM is clogging mailboxes, reducing productivity and increasing risks.
Solution: Secure eMail Subscription

Problem: Multiple network identities and passwords increase cost of IT management and decrease security
Solution: Novell Identity Manager
