symbiotic relationship with a company
like Siemens,” Bussiere affirms.
This combination of cutting-edge
technologies and services provides
the necessary level of cybersecurity
visibility to equip the CISO, C-suite
and Board of Directors with the
insights needed to focus on the issues
which matter most and enable better
strategic decisions.
Take a control system that starts
doing something unusual or unex-
pected, or a new valve configuration
that’s typically implemented on
Thursdays, but for some reason is
changed on a Sunday: An inexperi-
enced IT team working within an OT
environment might shut down the entire
plant to track this down unnecessarily.
In fact, many IT firms, lacking
Tenable and Siemens’ extensive
experience working with critical
energy infrastructure, would probe
these systems without realising it
could cause the site to crash. Tenable,
by contrast, is constantly operat-
ing safely in the background – with
Tenable.ot and Tenable.sc.
“They can get vulnerability and
threat data, information about
change configurations on the net-
work, and detect threats early as they
come into the environment,” says
Martinot. “We leverage that with other
technologies to see the full threat
environment. No interruptions to the
plant. No disruptions, not probing for
the information, just passively observ-
ing and querying devices.”
Proprietary Siemens platforms,
such as Managed Detection and
Response (MDR), built and overseen
by industry-leading experts, deploy
first-of-its-kind software to proac-
tively sort, understand and react to
what it is detecting at lightning speed.
