The Impact of SD-WAN Adoption
How SD-WAN is changing the market
- Simplicity from deployment to management
- An initiative to reduce operational expenses
- WAN redundancy
The conversation begins to shift around security, and more specifically, protecting an increasing attack surface as DIA and broadband circuits are incorporated into the WAN and replacing private circuits.
In many traditional WAN environments either Internet bound traffic is backhauled through data centers via private circuits and then out larger Internet circuits protected with perimeter firewalls with advanced threat and malware protection services, or if they have local Internet at these sites they have next-generation firewalls providing that perimeter security.
In today’s security landscape, stateful firewalling cannot protect against the ever evolving threats, and next-generation firewalls are still a big piece of the organization’s overall security posture puzzle.
Many SD-WAN vendors understand this and are making a big push to incorporate those features directly into their SD-WAN solution.
Some are partnering with existing third party vendors to provide these features. Others are integrating their existing security solutions into their SD-WAN platform, allowing for a one-box solution to provide both SD-WAN and NGFW functionality while configuring and managing from a single pane of glass.
