TeleGeography, a global telecommunications market research and consulting firm, has released its annual WAN Manager Survey: Cloud Connectivity & Network Security Report. The report reveals an opportunity for enterprises to further integrate networking and security and adopt new models to prevent data breaches. 

According to the survey, less than 20% of enterprises have fully or mostly integrated network and security teams. More than 40% have separate teams but work closely together on things like SD-WAN or hybrid network adoption. 15% have largely siloed networking and security operations.

“Enterprises are re-evaluating where security responsibilities sit within their IT operations. They are looking at greater integration between security and networking teams that will reduce risk while accelerating the adoption of networking technologies like SD-WAN. WAN Managers recognize the need for stronger relationships between these teams and we anticipate fully or mostly integrated teams growing over time,” said Greg Bryan, Senior Manager, Enterprise Research at TeleGeography. 

Interest in Zero Trust Security remains high among WAN managers, while only 8% have actually implemented the IT security model. 31% are considering Zero Trust Security, 19% are in the adoption phase with a fifth of respondents unfamiliar with the concept.

Zero Trust Security is an IT security model where, by default, no user or device is trusted inside or outside of the network. It offers policy-based controls rather than a legacy “castle and moat” architecture. It has been designed to prevent enterprise data breaches.

The survey collects around 100 responses from companies ranging in size from SMEs to Fortune 500 enterprises. It includes in-depth interviews with 15 respondents across 2018-19 to contextualize survey answers. Participating companies had a median annual 2018 revenue of about $7 billion and most were multinational in scope. In addition to security, the report covers Wide Area Networking (WAN) technologies, data center trends, and cloud adoption.
