Ditch Firewalls And Traditional Security Appliances
A castle and moat approach to security is the wrong model for today’s threats since it allows anyone that breaches the perimeter broad access within the victim’s environment, according to Zscaler CEO Jay Chaudhry. Yet despite the glaring weaknesses of a firewall-based approach to security, Chaudhry said businesses are still investing more in firewalls than any other security technology.
Firewalls assume that anyone inside the corporate network is trusted without requiring further verification, and requires the buildout of separate branches onto a wide area network (WAN) to support satellite locations, Chaudhry said.
Instead of connecting users to the corporate network, Chaudhry said it’s more secure to connect users directly to the application they need to use. By having all users accessing applications through an exchange that verifies their identity, Chaudhry said organizations can eliminate the need for WANs, firewalls, and traditional security appliances.
