Cisco offers cloud-based security for SD-WAN resources

Cisco adds support for its cloud-based security gateway Umbrella to SD-WAN software

SAN DIEGO— As many companies look to SD-WAN technology to reduce costs, improve connectivity and streamline branch office access, one of the key requirements will be solid security technologies to protect corporate resources.

At its Cisco Live customer event here this week, the company took aim at that need by telling customers it added support for the its cloud-based security gateway – known as Umbrella – to its SD-WAN software offerings. 

At its most basic, SD-WAN lets companies aggregate a variety of network connections – including MPLS, 4G LTE and DSL – into a branch or network-edge location and provides a management software that can turn up new sites, prioritize traffic and set security policies. SD-WAN's driving principle is to simplify the way big companies turn up new links to branch offices, better manage the way those links are utilized – for data, voice or video – and potentially save money in the process.

According to Cisco, Umbrella can provide the first line of defense against threats on the internet. By analyzing and learning from internet activity patterns, Umbrella automatically uncovers attacker infrastructure and proactively blocks requests to malicious destinations before a connection is even established — without adding latency for users. With Umbrella, customers can stop phishing and malware infections earlier, identify already infected devices faster and prevent data exfiltration, Cisco says.

Branch offices and roaming users are more vulnerable to attacks, and attackers are looking to exploit them, said Gee Rittenhouse, senior vice president and general manager of Cisco's Security Business Group. He pointed to Enterprise Strategy Group research that says 68 percent of branch offices and roaming users were the source of compromise in recent attacks. And as organizations move to more direct internet access, this becomes an even greater risk, Rittenhouse said.

“Scaling security at every location often means more appliances to ship and manage, more policies to separately maintain, which translates into more money and resources needed – but Umbrella offers an alternative to all that," he said. "Umbrella provides simple deployment and management, and in a single cloud platform, it unifies multiple layers of security, ncluding DNS, secure web gateway, firewall and cloud-access security,” Rittenhouse said.

“It also acts as your secure onramp to the internet by offering secure internet access and controlled SaaS usage across all locations and roaming users.”

Basically users can set up Umbrella support via the  SD-WAN dashboard vManage, and the system automatically creates a secure tunnel to the cloud.  Once the SD-WAN traffic is pointed at the cloud, firewall and other security policies can be set. Customers can then see traffic and collect information about patterns or set policies and respond to anomalies,  Rittenhouse said.

Analysts said the Umbrella offering is another important security option offered by Cisco for SD-WAN customers.

“Since it is cloud-based, using Umbrella is a great option for customers with lots of branch or SD-WAN locations who don’t want or need to have a security gateway on premises,” said Rohit Mehra, vice president of Network Infrastructure at IDC. “One of the largest requirements for large customers going forward will be the need for all manner of security technologies for the SD-WAN environment, and Cisco has a big menu of offerings that can address those requirements.”
