This is another service that forces users through the cloud instead of direct access to the organization's internet portal. However, in this case it is not just a content delivery issue for a website with which we are concerned - outside-in access, so-to-speak. Rather it is outward-looking in that it is the organizations' employees, not its customers, who get the advantage. Zscaler is, in my view, a secure data center in the cloud. That is saying a lot, but Zscaler delivers and has been since 2008.

"I pushed a proxy auto-config (PAC) file to each test workstation that forced all network traffic to flow through Zscaler where traffic inspection takes place and security rules are applied. The best part of using a PAC file for endpoint configuration is that users won't even notice a change in their browsing and email experience. The PAC file also forces the user's device to proxy all traffic through the Zscaler network. Administrators can also choose to protect entire networks using site-to-site IPsec VPNs.
Zscaler protects Windows, Mac, Linux and mobile platforms such as iPhone, iPad and Android against threats by scanning incoming and outgoing traffic from websites, social apps, cloud apps and email."

“The Zscaler solution has some additional advantages over Forefront TMG’s native web protection mechanisms. With a cloud-based solution, Zscaler’s protection can also be extended transparently to mobile users, keeping them safe regardless of where they are. Zscaler has more than 100 datacenters worldwide, ensuring quick response times and low latency wherever the mobile user happens to be. Integrating individual clients can be done using proxy PAC files to route traffic to Zscaler’s datacenters. Additionally there is an option to install an agent on the client to forward traffic, which has the benefit of preventing the end user from disabling proxy settings to bypass content filtering restrictions.”

"Protecting your network perimeter with security software or appliances is a pointless exercise when your typical user is a laptop- or smartphone-toting mobile worker or your business has numerous branch offices… Zscaler's service aims to provide security for corporate HQs, branch offices and mobile workers from the cloud, without the need for onsite hardware, software or client agents."

"In just two years, Zscaler's cloud security service has grown to over 40 data centers, processing over a billion transactions a day to secure millions of enterprise, SMB and Service Provider customers."
The Internet is an indispensable small business tool, but using it safely means guarding your small business against myriad online threats and ensuring that employees aren't putting the company at risk by using Web access in risky or inappropriate ways. Small Business Computing found ZScaler's SaaS- based Web Security Cloud for Small Business very promising for small business security, as it does not require deploying and managing security appliances and PC-based anti spyware/virus/firewall utilities.
