Cybersecurity Services in Greensburg, PA

A 60-person precision manufacturer off Route 30 in Greensburg has just been told by its largest customer — a defense prime — that it must demonstrate CMMC Level 2 readiness within nine months or lose the contract. The internal "IT person" is a capable systems admin, but he has never written a System Security Plan, never run a tabletop exercise, and has no tooling that produces the evidence an assessor will ask for. The owner does not want a Fortune 500 security stack. He wants someone local who can quietly fix this without disrupting the shop floor.

That scenario plays out across Westmoreland County every quarter — sometimes it is CMMC, sometimes a failed cyber-insurance questionnaire, sometimes a ransomware scare at a peer company that finally got leadership's attention. The case below is anonymized but representative of the cybersecurity services Greensburg, PA businesses actually engage us for.

The challenge

The manufacturer's environment looked typical for a 60-person shop: a hybrid Microsoft 365 tenant, an aging on-prem file server holding controlled unclassified information (CUI), a flat network where the CNC machines shared broadcast space with guest Wi-Fi, and a handful of vendor remote-access tools no one had inventoried in years.

A two-week assessment surfaced the issues that matter to an assessor and to an attacker:

• MFA was enabled for email but not for VPN or the ERP system.
• Endpoint protection was the bundled AV that shipped with the laptops; there was no EDR, no centralized logging, and no retention policy.
• Local admin rights were universal. Two former employees still had active accounts.
• Backups existed but had never been test-restored, and the backup server lived on the same VLAN as production.
• There was no written incident response plan, no documented data flow for CUI, and no evidence trail an auditor could review.

An assessor does not grade your intentions — they grade the evidence your tools produce on a Tuesday afternoon when nobody is watching.

How it was solved

We sequenced the work in three waves so the shop floor never lost a shift.

Wave one — contain the obvious risk. Inside the first 30 days we deployed managed EDR across every endpoint and server, enrolled the environment in 24/7 SOC monitoring out of our Pittsburgh operations, enforced phishing-resistant MFA on every external-facing system, and rotated or disabled the stale accounts. Local admin rights were stripped and replaced with a privileged-access workflow.

Wave two — segment and document. The flat network was split into VLANs separating CUI systems, general office, CNC/OT equipment, and guest traffic. We stood up centralized logging with 12-month retention, built the System Security Plan and Plan of Action & Milestones against the NIST SP 800-171 control set, and mapped the CUI data flow end-to-end. Backups were moved to an immutable, off-tenant target and tested monthly.

Wave three — prove it works. We ran a tabletop exercise with the leadership team simulating a ransomware event during a production week, then a technical purple-team test against the new controls. Findings fed back into the POA&M.

Outcomes

TL;DR: Layered controls plus an evidence-producing toolset moved this shop from "hope the auditor is lenient" to a defensible, documented security posture in under six months.

By month six the manufacturer passed a third-party CMMC readiness review with two minor findings, both remediated within two weeks. Cyber-insurance renewal — which had been in jeopardy — came back with a lower premium because the carrier's questionnaire could now be answered honestly with "yes" on MFA, EDR, immutable backups, and 24/7 monitoring. Mean time to detect a simulated intrusion in the purple-team exercise dropped from "never noticed" to under 15 minutes.

The owner kept his contract. The systems admin kept his job and got better tools. Production never lost a shift to the rollout.

Who this fits

This engagement model is built for organizations between roughly 20 and 300 employees in Greensburg, Murrysville, Latrobe, Irwin, Mt. Pleasant, Jeannette, and the broader Westmoreland and Allegheny County corridor. It fits especially well when:

• A customer, regulator, or insurance carrier has put a deadline on the calendar (CMMC, HIPAA, PCI-DSS, SOC 2, or a tightened cyber questionnaire).
• The internal IT team is competent but stretched, and security keeps losing to operational tickets.
• Leadership wants one accountable local partner rather than a stack of disconnected point vendors.

Why PGH Networks for cybersecurity services in Greensburg, PA

We are a Pittsburgh-based MSP and our engineers drive to client sites across the metro every week — Greensburg is well inside our 75-mile service radius from 15220. Three things tend to separate us from the field:

Compliance depth, not compliance theater. We write the SSP, build the POA&M, sit with you in the assessor interview, and produce the artifacts the framework actually requires. CMMC, HIPAA, and PCI work is done by engineers who have done it before, not handed off to a checklist.

An AI-enablement practice attached to the security practice. As clients roll out Microsoft Copilot, custom GPTs, and agentic workflows, we govern data exposure, sensitivity labeling, and prompt-logging as part of the security program — not as an afterthought six months later.

Local accountability. One service manager, one vCISO, one number to call. No offshore tier-one queue between you and the engineer who knows your network.

The right question to ask a security provider is not "what tools do you sell" but "what evidence will my auditor, my insurer, and my biggest customer see next quarter."

Takeaway and next step

If a deadline, a questionnaire, or a near-miss has put cybersecurity at the top of your agenda, the path forward is not a 40-page proposal — it is a focused assessment that tells you, in plain English, where the real risk is and what the next 90 days should look like.
