Cyber Security - Solution Architecture Design, & Implementation

Transform Fragile OT Networks
Into Secure, Modern Infrastructure

In complex industrial environments, aging networks and ad hoc changes create hidden risks for safety, uptime, and digital initiatives. Dexcent’s Solution Architecture, Design, and Implementation services modernize your OT infrastructure to align with industry standards, support smart manufacturing, and strengthen Cyber Security.

Read “Building the Backbone of Resilience” to see how modern OT architecture strengthens reliability, security, and long-term performance.

You Cannot Modernize
What You Cannot Trust

Most OT networks were never designed for today’s realities. Over time, projects, vendors, and emergency fixes layer on changes that leave you with a fragile mix of old and new equipment, incomplete documentation, and uncertain Cyber Security posture.

Common challenges we see include:

Legacy switches, servers, and firewalls that are out of support and difficult to replace without risking downtime.
Flat or poorly segmented networks that mix business, engineering, and control traffic.
Inconsistent or informal remote access that makes vendor support convenient but introduces a serious Cyber Security risk.
Little or no visibility into OT assets, firmware versions, and vulnerabilities across sites.
Outdated drawings and IP schemes that make every change slow, stressful, and dependent on a few individuals.

With regulatory pressure increasing and digital initiatives demanding more data, “just keep it running” is no longer enough. You need a network that protects operations today and supports where your organization is heading.

Design And Implementation
That Go Beyond A Network Diagram

Dexcent’s Solution Architecture, Design, and Implementation service gives you more than a set of drawings. We help you design and deploy an OT infrastructure that follows proven industrial reference models and is built for reliability, Cyber Security, and future growth.

Our consultants and OT specialists bring deep ICS and networking expertise to:

Map your current OT infrastructure and rationalize it against the Purdue model and relevant standards such as ISA/IEC 62443 and TSA pipeline security directives, where applicable.
Design segmented architectures that define clear zones, conduits, and an industrial DMZ to support secure IT and OT convergence.
Specify and implement core infrastructure, including server virtualization, firewalls, switches, routing, and secure remote access solutions.
Deploy asset discovery, intrusion detection, endpoint protection, and vulnerability management platforms so you can see and manage risk across your OT estate.
Produce the documentation operations teams need, from network and rack drawings to IP addressing schemes, patch panel layouts, and as-built packages.

Engagements can range from complete OT network modernization or greenfield installations to focused projects such as iDMZ implementation, remote access redesign, or performance troubleshooting. Work can be executed remotely, on-site, or through a blended approach, depending on the scope and risk profile.

Want a deeper look at how architecture, design, and disciplined implementation build long-term resilience? Our ebook “Building the Backbone of Resilience” explains how modern OT architecture improves reliability, strengthens Cyber Security, and prepares your facilities for digital initiatives.

From Fragmented Networks To Future Ready OT Infrastructure

With Dexcent’s Solution Architecture, Design, and Implementation service, your organization gains:

Reliability

A modern, documented OT network that reduces unplanned downtime from hardware failures, misconfigurations, and fragile one-off changes.

Security

System Architecture and security controls that align with industrial Cyber Security standards, supporting segmentation, secure remote access, and continuous monitoring across OT environments.

Readiness For Digital & AI

High bandwidth, well-segmented networks that can support Industry 4.0 initiatives, advanced analytics, and AI-driven optimization without compromising safety or reliability.

Confidence & Compliance

Clear drawings, inventories, and change records that make it easier to plan future projects, satisfy auditors, and demonstrate that OT infrastructure is managed and secure.

You do not just get an infrastructure project. You get a partner who understands your operations, your risk profile, and the regulatory landscape that shapes how your OT environment must evolve.

OT Expertise
Meets Strategic Foresight

Dexcent focuses on OT infrastructure, not generic IT. Our teams understand industrial control systems, SCADA platforms, and the constraints of running plants, pipelines, and utilities that cannot simply be rebooted.

We bring together:

OT centric architects and engineers who design networks specifically for ICS environments.
Experience with reference architectures for leading SCADA and control system vendors, including enterprise-scale deployments.
Practical delivery models that support both large, multi-site projects and smaller initiatives that help you build confidence in Dexcent’s capabilities over time.
