Top Layer Networks Delivers New IPS Solution for Managed Service Providers and Internal Corporate Networks

The Attack Mitigator IPS 5500-50 Provides the Most Comprehensive 100Mbps Protection

London, March 9, 2005 – Top Layer Networks (, the global leader for intrusion prevention, today announced the availability of its Attack Mitigator IPS 5500-50, a new mid-range solution that provides superior protection against cyber threats for organisations that have networks or network segments operating at up to 100Mbps. The new product uses the same hardware and features available in Top Layer’s industry-leading 8 gigabit solution, making it a compelling solution for organisations needing a feature-rich security appliance at performance levels of 100Mbps. This new solution will allow service providers to offer their customers powerful protection at an economical price point and will help enterprises roll out advanced security protection throughout their network and secure individual departments or partner portals.

“Small service providers and small/medium businesses encounter serious and disruptive network security breaches on a daily basis, but have had few choices for advanced network security products,” said Jeff Wilson, principal analyst of Infonetics Research. “Products like Top Layer's new Attack Mitigator 5500-50 address this growing need perfectly by offering enterprise-grade security at a cost that is attractive for a smaller organisation.”

“Service providers are faced with having to offer the best protection to their customers at a price point that is economical and compelling. Their customers face the same security threats the Global 2000 face, and require the same types of protection more commonly afforded to larger organisations,” said Mike Paquette, vice president of marketing and product management at Top Layer. “The new release of our Attack Mitigator IPS 5500-50 will also allow larger enterprises to better protect their internal departments at a price point more in line with their budgets.”

The IPS 5500-50 is a 100Mbps IPS solution for network-level and application-level protection from cyber threats including undesired access, malicious content, such as viruses, worms, Trojans and other remote exploits, and rate-based attacks, such as DoS, DDoS and other flood attacks. It is the latest addition to Top Layer’s flagship Attack Mitigator Ô IPS 5500 family of intrusion prevention solutions. The IPS 5500-50 includes:

Ø Advanced Protection Mechanisms - The IPS 5500-50 inspects 100% of network transactions with sophisticated anti-DDoS algorithms, its high performance Deep Packet Inspection Engine and its Stateful Analysis Firewall Filters.

Ø High Detection Accuracy – Unlike signature-based IPS solutions, that are notorious for generating false positives, the IPS 5500-50’s proprietary Advanced Protocol Validation Modules eliminate false positives.

Ø Protection Against Zero-Day and Unknown Exploits – The IPS 5500-50’s proprietary Advanced Protocol Validation Modules provide leading edge protection against server attacks, including Microsoft vulnerabilities. These Advanced Protocol Validation Modules work by inspecting every packet and determining whether the stream of packets that makes up a transaction violates Permitted Protocol Usage.

Ø Best-in-Class DDoS Protection - DDoS attacks now account for the greatest financial losses to businesses worldwide, and no IPS would be complete without comprehensive protection from the most sophisticated and devastating DDoS attacks. The IPS 5500-50 utilises patented DDoS protection mechanisms to offer the most comprehensive protection from all types of DoS and DDoS attacks.

Ø Advanced Stateful Firewall Filters – Many attackers gain undesired access via compromised or non-performing firewalls. The IPS 5500-50 has tightly integrated Advanced Stateful Firewall Filters with all of its IPS protection mechanisms enabling it to deliver superior performance.

Ø Reporting and Accounting – Top Layer Networks provides clear documentation of protection and statistical analysis of detected and mitigated attacks. The IPS 5500-50 also generates clear reports on threats, network performance, attack behaviour and in-depth details on individual vulnerabilities.
