SD-WAN security is strong but
additional security protocols
may still be required
Digital transformation has enabled businesses of all sizes to
create new ways of achieving operational efficiencies. But
just as technology has enabled business strategy to evolve,
so too have the risks to security. With data breaches and
ransomware attacks now a daily occurrence for businesses of
all sizes across the world, security is a critical component for
businesses to address from the start.
According to research from Global Market Insights, the
SD-WAN market will grow at a 60% compound annual
growth rate from 2018 to 2025 – demonstrating how the
adoption of the technology is rapidly increasing. However,
as with the implementation of any new technology, the
risks to security must be considered. High levels of security
are essential for SD-WAN, in particular, as in many cases
the network is built across public infrastructure, which could
potentially leave data exposed and vulnerable to threats.
The first design of SD-WAN was a building block
approach, comprising of a router, adding a firewall and
further equipment to ensure security. With the advent of
a software approach to SD-WAN, sophisticated security
features are built-in from the start, ensuring that at a base
level it includes industrial-grade encryption and a set of tools
to manage the end to end security over a public
