Traditional OT security can’t protect a connected world

You can’t assess risk without visibility

Without mapping communication between IT and OT assets, hidden dependencies and risks remain exposed.

Legacy segmentation can’t scale

Traditional firewalls and VLANs can’t adapt to hybrid environments or support real-time enforcement across modern and legacy OT.

Vulnerabilities turn into outages

When attackers exploit unpatched or unsupported systems, the impact spreads fast — from business systems into production or control layers.

Maintaining operations requires unified IT/OT resilience

Every organization depends on continuous uptime — whether it’s keeping the energy grid online, a production line running, or patients safe. Regulations like NIS2, DORA, and CIP demand that operators contain security incidents, not just detect them..

Attackers exploit the IT–OT bridge

Ransomware and remote access tools move laterally from corporate networks into production systems. Without segmentation, one compromise can stop operations.

Governments are mandating containment

New regulations require operators to isolate critical systems and prove they can sustain essential services during an attack.

Legacy defenses can’t keep pace

Perimeter tools don’t provide the visibility or agility needed to protect both IT and OT — allowing attackers to move freely once inside.

Secure digital transformation in OT environments with Illumio

Map IT and OT dependencies

Simplify security policy design by understanding communication and traffic flows.

Allow only what is verified

Prevent the spread of ransomware and other attacks by stopping all traffic except what is required for operations.

Reduce vulnerability risk

If a vulnerability is discovered in an asset, communication can be restricted until a patch is applied.

Respond quicker with more agility

Adapt policy for each system based on context and status rather than static firewall rules..

Disruption is prevalent and costly

97%

Almost all organizations report that an IT security incident impacted their OT environment.

46%

Almost half of organizations reported suffering from an OT security incident in the last 12 months.

12.6%

Most organizations report that cyberattacks affecting manufacturing or critical infrastructure often begin in IT corporate systems.
