Keeping company data secure can get tricky when collaborating with remote employees and contractors. Here’s how AdRoll, a marketing platform provider, addressed that issue using a cloud-based service.


Initially, internet performance was a problem for the company’s off-site contractors. AdRoll required contractors to connect through virtual private network (VPN) software to the company’s San Francisco firewall. Traffic bound for Amazon Web Services (AWS) and the internet was then sent out through a central connection to the public internet. Backhauling traffic through the San Francisco office created a chokepoint, adding latency to the mobile experience. It forced all of the mobile traffic through the company’s San Francisco Internet connection, ultimately saturating the line. There were also security issues as the VPN software required users be granted access to all network resources, not particular applications. For example, nothing prevented users who only needed the company’s web application from using secure socket shell (SSH) to connect to the company’s routers. “Traditional VPNs meant opening the door to everything,” says Dunne. The Cato Cloud solution allowed more specific permissions to be set, giving mobile users access only to necessary applications, and restricting them from critical company resources.
