for branch offices that were connected
directly to the data center,
where internal applications were
hosted and Internet traffic could
be filtered. But with working from
home becoming an option for
many employees, apps and data
need to be dispersed across locations.
IT teams face the challenge of
providing secure, authorised access
while maintaining quality of experience
across any device and location.
Network Security Meets
Security at the Edge
The Secure Access Service Edge, or
SASE model is becoming increasingly
important for many large organisations.
Already, 24 percent of
enterprises plan to develop strategies
to implement the SASE approach
outlined by Gartner, a consultancy,
by 2024 at the latest.
SASE is a cloud-centric architecture
that represents a convergence
of software-defined wide
area networking (SD-WAN) and
high security in a strategic edgeto-cloud
service that adds neither
hardware cost nor complexity. In
other words, SASE describes an
architecture that delivers network
services and security functions
as cloud services where they are
needed: On end devices and at the

edge, where a permanent connection
to networks is not possible or
even necessary.
Although each company is taking
a different path, a strategic SASE
vision includes both a fundamental
shift in access controls to where
they are needed - the end user and
the cloud edge – and the search
for less complexity. Convergence
of security functions in an efficient
as-a-service model are a good way
to achieve these goals.
In addition, SASE can focus on
supporting business agility to respond

changes, while at the same time

Large enterprises still operate
huge data centres. These
contain not only local SaaS
(Software-as-a-Service) applications,
but also network components
such as firewalls, load
balancers, intrusion detection and
prevention systems, routers and
