Cybersecurity Services for Manufacturers

A 120-person metal fabrication shop in the Mon Valley wins a subcontract on a Department of Defense program. Two weeks later, the prime contractor sends a flow-down notice: CMMC Level 2 attestation is required within the year. The same week, a spear-phishing email lands in accounts payable, and a CNC controller starts rebooting in a loop. Production stops for six hours while the team tries to figure out whether they've been breached or just had bad luck with a firmware update.

That is the moment most Pittsburgh-area manufacturers start seriously shopping for cybersecurity services for manufacturers — not before. This page walks through how a scenario like that gets resolved, and what a defensible security posture looks like for a shop between 50 and 500 employees in Allegheny, Washington, Westmoreland, Beaver, or Butler County.

The challenge

The fabricator's environment looked like a lot of regional manufacturers we assess. One flat network. Office PCs, ERP servers, and shop-floor HMIs all reachable from the same VLAN. Domain controllers running an OS that went end-of-support two years ago. A cyber insurance renewal application sitting on the controller's desk asking about MFA, EDR, and offline backups — answers the IT manager could not honestly check "yes" to.

Layered on top: the CMMC Level 2 requirement, which maps to NIST SP 800-171's 110 controls, plus a prime contractor asking for a System Security Plan and POA&M within 90 days. And an operations team that could not tolerate a maintenance window longer than a Sunday third shift.

Manufacturers rarely get breached because attackers are clever — they get breached because the network was built for uptime, not for isolation.

How it was solved

The first two weeks were assessment, not deployment. We ran an external attack surface scan, an internal vulnerability sweep, and — critically — a passive OT discovery on the plant floor so we could inventory PLCs, HMIs, and legacy Windows machines without touching production. That inventory drove everything after.

From there, the roadmap ran in three parallel tracks:

Contain the immediate risk. Deploy managed EDR to every endpoint that could take an agent. Enforce MFA on email, VPN, and remote admin. Move backups to an immutable, offsite target and test a restore. Retire two internet-facing services that had no business being exposed.

Segment IT from OT. Stand up a proper industrial DMZ. Put the shop-floor devices behind a firewall with explicit allow rules to the ERP and historian, and nothing else. Legacy HMIs that could not be patched got wrapped in compensating controls rather than ripped out.

Get compliance-ready. A CMMC Level 2 gap assessment against all 110 NIST 800-171 controls, followed by a written System Security Plan and a realistic POA&M. Quarterly tabletop exercises with the leadership team. Security awareness training tied to the actual phishing patterns the shop was seeing.

Outcomes

Within one renewal cycle, the manufacturer answered "yes" honestly to every question on the cyber insurance application and held its premium roughly flat in a market where similar shops were seeing double-digit increases or non-renewals. The CMMC gap list shrank from 47 open controls to 6, all with dated remediation plans acceptable to the prime. Ransomware simulation exercises showed lateral movement from a compromised office laptop no longer reached the shop floor.

Just as important: no unplanned production downtime was introduced by any of the security work. Everything that touched OT was staged, tested, and cut over during scheduled windows.

Who these cybersecurity services for manufacturers are built for

This work fits small and mid-market manufacturers — roughly 25 to 500 employees — within about 75 miles of Pittsburgh. Job shops, contract manufacturers, fabricators, plastics and food processors, and Tier 2/Tier 3 suppliers to aerospace, defense, medical device, and automotive primes. If you have a mix of modern IT and older OT, a compliance driver (CMMC, ITAR, NIST 800-171, or a customer questionnaire you cannot answer confidently), and no full-time security staff, this is written for you.

What's included

TL;DR: A defensible manufacturing security program combines OT-aware assessment, 24/7 monitoring, network segmentation, and compliance documentation — delivered without stopping the line.

Our cybersecurity services for manufacturers cover the full lifecycle: risk and OT asset assessment; managed detection and response with a 24/7 SOC; email security and phishing simulation; identity, MFA, and privileged access management; firewall and IT/OT segmentation; immutable backup and tested recovery; CMMC and NIST 800-171 readiness including SSP and POA&M authorship; vendor and supply-chain review; incident response retainer with a written runbook; and security awareness training localized to shop-floor realities.

For manufacturers already exploring AI on the plant floor or in the front office, we also bring an AI-enablement practice that helps you adopt copilots and vision systems without leaking proprietary CAD files, pricing, or ITAR-controlled data into public models.

Why PGH Networks

We are based in the Pittsburgh metro and drive to your facility — Coraopolis, Cranberry, Washington, New Kensington, Greensburg, Beaver Falls. Our engineers have worked inside regional plants and understand that a "quick reboot to apply a patch" can mean scrapping a $40,000 part on a five-axis mill. We hold the compliance conversation in plain language, write documentation that survives an auditor, and stay in the room during incident response instead of routing you to a ticket queue in another time zone.

The right partner treats your production schedule as a security requirement, not an obstacle to one.

Takeaway and next step

If the opening scenario sounded uncomfortably close to your shop — flat network, aging OT, a prime contractor asking harder questions each quarter, an insurance renewal you are quietly dreading — the path forward is not a product purchase. It is a two-week assessment that produces a prioritized roadmap you can actually fund and execute.

Contact PGH Networks at 724.888.7007 or via the contact form to schedule a manufacturing cybersecurity assessment. We will walk your floor, review your controls against CMMC and NIST 800-171, and give you a written plan before you sign anything longer-term.
