Attack Mitigator

Top Layers debut appliance is a useful device for quelling DoS and DDoS (distributed-denial-of-service) attacks while still allowing legitimate traffic through. Using custom chips and easily configurable thresholds to weed out likely troublemakers, IT managers should consider using the Attack Mitigator as the first line of defense of network resources—although it could become a single point of failure in some cases.

SHORT-TERM BUSINESS IMPACT // The product can be installed quickly, but IT managers should allocate plenty of time to get a base line of network traffic behavior. Once up and running, the Attack Mitigator should significantly reduce costly DoS attacks.

LONG-TERM BUSINESS IMPACT // As network attacks continue to evolve, enterprises will need to allocate significant resources to maintain the Attack Mitigator.

PROS // Zeros in on difficult-to-control DoS and DDoS attacks; allows good traffic even during heavy attacks; ably monitors ingress and egress traffic.

CONS // Could become a single point of failure; doesnt defend well when networks have more than one path to the Internet.
