    Problems We Solve for Manufacturers

    Three pressure points that keep plant managers up at night

    The Problem:

    Unplanned downtime costing $10K+/hour in lost production

    Our Solution:

    Proactive 24/7 monitoring catches problems before they stop your line. When issues hit, our team responds in under 15 minutes.

    The Problem:

    Your 'IT guy' wears too many hats—or you have no dedicated IT staff at all

    Our Solution:

    Get a full IT department at a fraction of the cost. We handle everything from helpdesk to network engineering so your people can focus on production.

    The Problem:

    Compliance pressure is mounting—CMMC, NIST 800-171, ITAR

    Our Solution:

    We build audit-ready documentation and controls from day one. Stay compliant without hiring a full-time compliance officer.

    OT / ICS Expertise

    Deep Operational Technology Capabilities

    We don't just manage office PCs. Our engineers are hands-on with the systems that run your production floor.

    SCADA & HMI Security

    Hardening, patching, and monitoring for supervisory control and human-machine interface systems.

    PLC & DCS Protection

    Security policies for programmable logic controllers and distributed control systems without disrupting automation.

    Purdue Model Segmentation

    Network architecture that isolates OT from IT — preventing lateral movement from corporate to production systems.

    Protocol-Aware Firewalls

    Deep packet inspection for Modbus TCP/IP, EtherNet/IP, OPC-UA, and other industrial protocols.

    MES/ERP Integration Security

    Secure data flows between manufacturing execution systems, ERP platforms, and the corporate network.

    Air-Gapped Backup Strategies

    Immutable, isolated backups for critical production configurations and CNC programs.

    We Understand Manufacturing IT

    "We know what it's like when a CNC controller goes down at 2 AM. We've been in the plant, on the floor, troubleshooting alongside your team. That's why we built our services specifically for manufacturers."

    Our engineers have hands-on experience with:

    OT/IT network convergence
    SCADA & HMI system security
    Plant floor network design
    Air-gapped backup strategies
    CMMC & NIST compliance
    Multi-facility IT management

    Your 3-Step Path to Reliable IT

    A proven process that gets manufacturers from reactive firefighting to proactive protection

    01

    Assess

    We audit your plant floor IT—networks, endpoints, OT systems, backups, and compliance gaps. You get a prioritized roadmap within one week.

    02

    Protect

    We segment your OT and IT networks, deploy endpoint security, harden backups, and close compliance gaps—all without disrupting production.

    03

    Support

    Ongoing managed services with guaranteed response times. Proactive monitoring, patch management, and a direct line to engineers who understand manufacturing.

    What's at Stake

    With the Right IT Partner

    • Predictable monthly IT costs—no surprise bills
    • Zero unplanned downtime from preventable IT failures
    • Compliance confidence for CMMC, NIST, and ITAR audits
    • Secure, segmented OT networks that protect connected equipment
    • A responsive IT partner who understands manufacturing schedules

    Without Action

    • Production stoppages from aging, unmonitored infrastructure
    • Ransomware risk to CNC machines, PLCs, and connected equipment
    • Failed compliance audits that cost you government contracts
    • Reactive break-fix costs that blow up your budget quarter after quarter

    What Manufacturers Say

    "Before Collett Systems, we were losing production time every week to IT issues. Now our plant floor network is segmented, our backups are solid, and I can't remember the last time we had unplanned downtime."

    — Plant Manager

    Precision Machining, West Bend WI

    "They segmented our CNC controllers from the corporate network and set up proper firewall rules for our EtherNet/IP traffic. Our Epicor ERP hasn't had a single unplanned outage since they took over."

    — VP of Operations

    Metal Fabrication, Hartford WI

    "We needed CMMC compliance to keep our defense contracts. Collett built the documentation, implemented the controls, and we passed the audit on the first attempt. No other MSP we talked to understood OT networks like they do."

    — Operations Director

    Defense Subcontractor, Germantown WI
