Simplifying OT Security Configuration: Power Without Complexity

Operational Technology

October 24th, 2025

In today’s operational technology (OT) environments, complexity has become the norm. Across manufacturing plants, utilities, energy facilities, and industrial sites, engineers are tasked with managing sprawling networks of PLCs, HMIs, controllers, sensors, and switches — often built over decades, with equipment from multiple vendors. Ensuring uptime is hard enough; adding security configuration on top can feel like an uphill battle.

The challenge isn’t a lack of security awareness — it’s the administrative burden of configuring and maintaining it all. Every new device, every policy update, every remote connection adds another layer of complexity to manage.

The Legacy of Complexity in OT Configuration

For years, OT security was defined by command lines and manual configuration. Engineers used SSH sessions, DOS terminals, and vendor-specific syntax to set up access rules, routing, and segmentation. A mistyped command could take a system offline.

As graphical interfaces arrived, things improved — but only slightly. Each switch or controller vendor offered its own GUI, each with unique logins, design quirks, and update processes. Engineers still had to jump between multiple systems to perform basic tasks.

Even today, VLAN sprawl, firewall rule fatigue, and VPN configuration challenges continue to burden teams. What began as well-intentioned security measures have turned into administrative mazes. VLANs multiply, firewall lists grow, and VPNs add overhead that’s both time-consuming and brittle to maintain — especially in brownfield environments filled with legacy equipment.

The result? Security becomes harder to implement, not easier.

OT and ICS engineers need tools that keep pace with this reality — powerful, yet simple. That’s where Byos comes in.

A Different Approach: Byos Makes Security Simple

Byos takes a fundamentally different approach to OT security configuration. Instead of forcing engineers to learn yet another command set or navigate multiple vendor dashboards, Byos delivers hardware-enforced microsegmentation that’s easy to deploy, manage, and scale — all through a single, intuitive centralized control and data plane — the Byos Management Console. Purpose-built for managing distributed devices in industrial environments, it gives a powerful, single-pane interface for real-time visibility, granular control, threat monitoring, and secure, remote asset access — without exposing systems to the internet.

With Byos, OT and ICS engineers can:

• Activate devices quickly: Plug them in, assign them to a logical zone, and they’re secure — no re-architecting or downtime required.
• Manage users and policies visually: Define who can talk to what, and over which ports or protocols, with just a few clicks.
• Integrate with existing networks: Byos overlays seamlessly onto current infrastructure, protecting brownfield environments without expensive upgrades.
• Enforce Zero Trust at the edge: Every device is isolated and cloaked from discovery, reducing the attack surface instantly.

What makes this powerful is not just the security model — it’s how accessible it is for the people running the plant. Byos empowers engineers to deploy modern security controls without needing deep networking or cybersecurity expertise.

Ease of Configuration Translates to Real-World Efficiency

For OT engineers, simplicity isn’t just convenience — it’s a form of resilience. Every minute spent configuring complex systems is time taken away from maintaining operations, responding to alarms, or optimizing production.

Byos reduces this burden in several ways:

1. Faster deployment
Plug-and-play setup means sites can be secured within hours, not weeks. There’s no need to redesign the network or create intricate VLAN structures.

2. Reduced errors
Intuitive, guided configuration eliminates the risk of costly misconfigurations that could expose assets or disrupt operations.

3. Lower training overhead
New staff can be brought up to speed quickly — there’s no requirement to memorize CLI syntax or vendor-specific commands.

4. Centralized visibility
Through the Byos Management Console, security and OT teams can monitor, adjust, and enforce policies across all sites in one place.

The result is a streamlined security posture that fits into the day-to-day rhythm of an OT environment — not one that constantly works against it.

Designed for the Way OT Teams Actually Work

In our conversations with industrial operators, one theme comes up again and again: security tools often feel like they were built for IT teams, not for engineers on the plant floor. They require dedicated specialists, expensive integration projects, or deep knowledge of protocols that have little to do with running a production line.

Byos was built differently. The goal is to make security administration as intuitive as operating a machine HMI. It’s built for the people who already understand their environments — giving them the confidence to protect assets quickly and effectively.

That’s why organizations across manufacturing, energy, utilities, transportation, and data centers are adopting Byos Secure Edge™ solutions. Whether protecting legacy PLCs or enabling secure remote maintenance connections, Byos brings consistency and ease of use to every environment.

Why Simplicity Matters

Security that’s too complex rarely gets implemented properly. The more steps, scripts, and settings required, the greater the chance that teams skip, misconfigure, or delay them. In critical infrastructure, that’s not just inefficient — it creates serious risks.

Byos believes simplicity is security. When configuration is fast, intuitive, and reliable, adoption improves — and so does protection. By reducing friction, Byos helps OT teams stay secure by default, rather than by exception.

Conclusion: Security Built for Engineers

Plant and OT engineers have enough to manage already — from uptime and performance to safety and compliance. Security shouldn’t add to that list of headaches.

With the Byos Secure Edge™ platform, configuration becomes straightforward, scalable, and approachable. OT and ICS engineers can secure devices, isolate assets, and enforce Zero Trust principles without leaving their comfort zone. Simplicity isn’t just a feature — it’s the enabler of real, sustainable OT security.
