Top Intrusion Prevention System Appliance: A 9-Vendor Battle

Juniper SRX5800

Juniper's SRX5800 has been a mainstay in many large telecommunications and enterprise environments. It carries the distinction of providing security with minimal impact to network traffic performance, according to Rob Ayoub, researcher director at NSS Labs. But Juniper has struggled with its SRX line in recent years and poor results in NSS Labs testing. The IPS appliance received below-average marks compared to its competitors. It got an 89.2 percent effectiveness score, having blocked 90.3 percent of attacks against server applications and 88.3 percent of attacks against client applications in NSS Labs testing. The SRX5800 was the only appliance to get the "Caution" rating from NSS Labs engineers.
