Solutions · OT and IIoT

Protect the factory floor.

Operational technology and IIoT were never built for the open network. We give you visibility, segmentation and monitoring without touching uptime.

Overview

Uptime first, security always.

Manufacturing and process industries run control systems that were designed to run for decades, not to sit on an open network. As IT and OT converge, those systems become reachable, and the attack surface grows fast. Open Systems secures OT and IIoT the way the plant needs it: visibility and segmentation that never put uptime at risk, monitored around the clock.

The challenge

What you are up against.

Legacy by design

Control systems were never built to be online or patched often.

Uptime cannot break

A security change that stops the line is not an option.

IT and OT converge

Connecting the plant to IT widens the attack surface fast.

Thin OT skills

Few teams have both OT and security expertise on call 24/7.

Our approach

Segment, watch, answer for it.

OT-aware firewall to segment industrial networks from IT and from each other
Zero-trust access for maintenance staff, integrators and vendors
Passive monitoring that adds visibility without touching the process
Level-3 engineers operate and respond 24/7, no L1, no L2

Benefits

What you get.

OT and IIoT segmented and protected without downtime
One policy model across IT and OT
Sovereign data residency for sensitive operational data
24/7 Level-3 operations so a lean plant IT team is not alone

OT Firewall

A firewall that speaks the shop floor.

An OT firewall safeguards communication between industrial control systems and external networks. Unlike a traditional IT firewall, it understands industrial protocols and the operational realities of the production floor, and it is built to survive industrial environments while giving you the granular visibility and control that critical infrastructure needs.

Zero Trust Network Access secures remote entry points, but the core of the OT environment needs its own defence. Our OT firewall goes past access control: it watches traffic flows inside the OT network so every packet is accounted for and inspected, with threat detection built in.

How we protect the OT network

Two moves that stop lateral movement.

A dedicated firewall inside OT

OT environments often run without visibility or control, except where traffic leaves the facility for the internet. A threat detected there is usually detected too late. We put a dedicated firewall with intrusion detection inside the environment, so traffic is monitored and threats can be isolated at the source.

OT segmentation

Thorough segmentation limits lateral movement after a breach. We provide the technical support to implement it, and our policy and zoning concepts keep it manageable afterwards instead of turning into a rulebase nobody dares to touch.

Proactive monitoring

Watch continuously, answer for it.

The firewall continuously monitors the OT environment, capturing and analysing traffic patterns and identifying anomalies that could signal a breach. In an ecosystem where a small irregularity can precede a targeted attack or a system failure, that level of scrutiny is the point.

When something is detected, remediation starts before it escalates. Level-3 engineers, senior specialists with no ticket triage in between, decide what happens to a production system. That is deliberate: nobody automates a shutdown on a running line without a human owning the call.

FAQ

Questions from the plant floor.

Will any of this stop the production line?

No, and that is the constraint we design to rather than a promise bolted on afterwards. Visibility is added passively, so monitoring never touches the process. Segmentation is planned against your zones and rolled out in agreed windows, and no change to a running line is automated without a human owning the call.

Our controllers cannot be patched. Does that rule us out?

The opposite: it is the normal starting point. Control systems were built to run for decades, not to be patched monthly, so the defence has to sit around them. A dedicated firewall inside the OT environment plus thorough segmentation contains what a vulnerable device could otherwise be used to reach, without anyone touching the device itself.

How is an OT firewall different from the IT firewall we already have?

It understands industrial protocols and the operational realities of a plant floor, and it is built to survive an industrial environment. Just as important is where it sits: inside the OT network rather than only at the point where traffic leaves for the internet. A threat detected at the perimeter of a plant is usually detected too late.

We have IT security already. Why a separate approach for OT?

Because the priorities invert. In IT, confidentiality usually outranks availability; on a production line, availability is safety. IT and OT converge anyway, which is what widens the attack surface, so the goal is one policy model across both with an enforcement approach in OT that respects uptime. You get the single model without the plant inheriting IT's assumptions.

Who watches it at 3am? We have two people in plant IT.

Level-3 engineers do, 24/7, follow-the-sun. That is the reason this is a managed service rather than another appliance: few teams have both OT and security expertise on call around the clock, and an anomaly on a control network at three in the morning is exactly when that gap costs you.

How is OT priced?

Per site and month, not per user, because a plant floor does not scale with headcount. Secure Access OT starts at CHF 270 per site and month and is not subject to the user volume discount. The full context is on the pricing page.

How do maintenance staff and external integrators get in?

Through zero-trust access scoped to the specific system, for the specific window, with the session logged, instead of a flat VPN into the plant network. Third-party remote maintenance is one of the most common ways an OT environment gets reached, so it is treated as a first-class case rather than an exception.
