When remote workers want to securely access their corporate network, they typically do so through a secure socket layer (SSL) VPN, says Chris King, director of product marketing for Palo Alto Networks. But companies don't have VPN control when the remote worker is accessing a cloud-delivered app. GlobalProtect improves security by connecting to the enterprise's nearest NGFW.
A remote worker in Albany, N.Y., for example, could connect to his company's NGFW in Schenectady, said King. "I can connect to that gateway and have security policy be enforced." The new PAS-5000 series of firewall appliances--the 5020, 5050 and 5060--have the capacity to screen network traffic at speeds up to 20Gbps, King says.
Next-generation firewalls provide all of the expected security of traditional firewalls, but also offer integrated intrusion prevention security, full stack visibility that offers protection tailored to specific applications and extra firewall intelligence, he says.
In an October 2009 report, Gartner stated that only 1 percent of Internet connections were protected by NGFWs, but that by 2014, that number would rise to 35 percent and that 60 percent of new firewall purchases that year would be of NGFW technology.
