Managed Cybersecurity Services in Greensburg, PA

A controller at an 80-person precision machining shop off Route 30 in Greensburg gets a letter from a defense prime: their next contract renewal requires CMMC Level 2 attestation within nine months. The shop has an internal IT generalist, a mixed bag of firewalls and switches installed over a decade, and no one watching the network after 5 p.m. The controller starts searching for managed cybersecurity services in Greensburg, PA — not a product pitch, but a partner who can close the gaps before the auditor arrives.

That scenario is common across Westmoreland County right now. What follows is a composite case study — details anonymized — showing how PGH Networks approaches this kind of engagement, and what the reader should expect if they're in a similar spot.

The challenge

The manufacturer had roughly 95 endpoints across two buildings, a small ERP server on-premises, and Microsoft 365 for email and files. A quick discovery call surfaced the real risks well before any formal assessment:

• No 24/7 monitoring. Alerts from the existing antivirus went to a shared inbox nobody read overnight.
• A flat network — CNC controllers, guest Wi-Fi, and finance workstations all sat in the same broadcast domain.
• Local admin rights on most workstations, and MFA enabled on email but not on the VPN.
• No written incident response plan, no evidence of log retention, and no system security plan (SSP) — three items that would fail a CMMC assessment on day one.
• A cyber insurance renewal 120 days out with a new questionnaire asking about EDR, immutable backups, and privileged access management.

The gap between "we have antivirus" and "we can prove control effectiveness to an auditor" is where most Greensburg-area SMBs actually live.

The internal IT lead wasn't the problem — he was doing three jobs. The problem was that compliance-grade security is a specialty, and staffing a 24/7 SOC inside an 80-person business doesn't math out.

How managed cybersecurity services in Greensburg, PA solved it

PGH Networks scoped a phased engagement rather than a rip-and-replace. The sequence mattered because the CMMC clock was already running.

Weeks 1–3: Assessment and quick wins. A NIST 800-171 gap assessment mapped each of the 110 practices to current state. In parallel, MFA was extended to VPN and all admin accounts, local admin rights were removed from standard users, and a managed EDR agent replaced the legacy AV across every endpoint.

Weeks 4–8: Monitoring and segmentation. Endpoints, firewalls, and Microsoft 365 were onboarded into a 24/7 SOC with a defined escalation runbook naming the controller and the plant manager. The network was segmented so the shop-floor VLAN could no longer reach finance, and guest Wi-Fi was isolated entirely.

Weeks 9–16: Compliance evidence. This is the part most providers skim. PGH Networks produced the SSP, the plan of action and milestones (POA&M), and the policy set the auditor would actually read — access control, incident response, media protection, configuration management. Log retention was configured to 12 months with tamper-evident storage.

TL;DR: Managed cybersecurity in a regulated environment is 40% tools, 60% documented evidence — and the documentation is what most SMBs are missing.

Ongoing: Monthly vulnerability scans, quarterly patch and policy review, and a tabletop incident response exercise before the audit window opened.

Outcomes

By the time the CMMC readiness assessor walked in, the manufacturer had:

• A monitored environment with mean time to acknowledge under 15 minutes on high-severity alerts, tracked in a monthly report the controller could hand to ownership.
• Cyber insurance renewed without a premium increase — the carrier's new controls questionnaire came back clean.
• A shrunk attack surface: local admin removed from 92 of 95 workstations, MFA on 100% of remote access, and shop-floor systems isolated from corporate.
• A complete SSP and POA&M package. The readiness assessment identified a handful of minor items to close before the formal C3PAO visit — not the scramble the shop feared.

No client names, no invented percentages — those are the categories of outcome to expect from a properly scoped engagement.

Who this fits in the Westmoreland County corridor

This model fits organizations of roughly 25–250 employees in Greensburg, Latrobe, Murrysville, Irwin, Delmont, and the broader Route 30 / Route 22 corridor who face at least one of the following:

• A regulatory driver — CMMC, HIPAA, PCI DSS, or SEC cybersecurity disclosure rules.
• A cyber insurance renewal with tighter control requirements.
• A recent near-miss (phishing, business email compromise, ransomware attempt).
• A lean internal IT team that owns everything and can't specialize in security.

Manufacturers, healthcare practices, law firms, and professional services companies across the Pittsburgh metro see the same pattern.
