or laptops, and not be constrained by the
bandwidth limitation,” said Tillson.
The solution worked as planned and enabled
the workers in China to access the applications
they needed far more quickly and efficiently
than what would have been possible using the
previous remote access solution.
Global rollout to anticipate
a global crisis
As the COVID-19 virus began expanding
outwards from China, TT Electronics had
to move quickly to make a decision on its
remote access solution. Foreseeing the
global remote working situation that was,
at this point, still a few weeks away, TT
Electronics made the move to extend ZPA to
the majority of its employees globally.
“We needed to roll it out quickly. We were
really concerned the current solution we
had in place just wouldn’t be sufficient. The
bandwidth issues, the usability problems –
Zscaler doesn’t have any of that, it just works
and that’s what we needed,” said Tillson.
TT Electronics rapidly set up RDS in the
majority of its sites and installed the ZPA
client on corporate machines in order to
enable home working for its employees
within the time span of around three weeks.
Turning away from traditional VPN
In March 2020, after a three-week
deployment period, 3,000 TT Electronics
staff were able to access their applications
from home securely and continue working as
usual, when many other companies globally
were still struggling to maintain application
availability for their remote workers.
“ZPA has been a real game-changer for us.
Traditional VPN is always difficult to configure,
it requires hardware on-site, it’s difficult to
scale and there are bandwidth constraints
between the remote access network and our
MPLS to consider. We wouldn’t have been
able to have more than a dozen employees
working from home using a traditional VPN,
but ZPA has given us the security and the
flexibility we needed to enable remote working
at the scale we suddenly needed,” said Tillson.
Making IT look easy
As is often the case with IT in the enterprise,
end-users and the leadership team don’t
necessarily see or understand the scale of
the work being done behind the scenes
– they just appreciate it when it works as
intended. In the case of Tillson and his
team, however, feedback from the wider
organisation has been incredibly positive.
“All of our users are actually amazed at how
they can work from home with ZPA. They
