Cybersecurity Services in McMurray, PA

A 55-person professional services firm off Waterdam Road in McMurray came to us with a familiar problem: their cyber insurance carrier had sent a renewal questionnaire with 42 questions, and roughly half of the honest answers would have been "no." The renewal date was six weeks out. Their internal "IT person" was a talented office manager who also ran billing. Cybersecurity services in McMurray, PA had, up to that point, meant a firewall someone installed in 2019 and a hope that nothing bad would happen.

This is the story of what we actually did — anonymized, but structurally accurate to the kind of engagement we run across Washington County and the South Hills every month.

The challenge

The firm handled sensitive client financial data and had contractual obligations with two enterprise clients that required documented security controls. Three pressures hit at once:

1. The insurance carrier wanted MFA on email, privileged accounts, and remote access — plus EDR (not antivirus), immutable backups, and a documented incident response plan.
2. One enterprise client had forwarded a vendor security questionnaire referencing NIST CSF and SOC 2-style control language.
3. Two employees had already clicked phishing links in the prior quarter. Nothing had been exfiltrated that anyone could see — but nobody could actually prove that, because there were no logs older than 14 days.

When a business can't prove what didn't happen, the insurance carrier assumes the worst and prices accordingly.

Compounding all of this: the firm ran Microsoft 365 Business Standard with default settings, shared admin credentials among three people, and had a flat network where the guest Wi-Fi could reach the file server.

How it was solved: cybersecurity services built for McMurray-area businesses

We ran a two-week assessment mapped to CIS Controls v8 IG1, which is the right altitude for a business this size — rigorous enough for insurance and enterprise clients, not so heavy it stalls out. From there, remediation ran in three waves.

Wave 1 — Identity (week 1–2). Enforced conditional-access MFA across Microsoft 365, separated admin accounts from daily-use accounts, killed legacy authentication protocols, and turned on unified audit logging with a 1-year retention. This alone answered eleven of the insurance questions.

Wave 2 — Endpoints and email (week 2–4). Deployed managed EDR with 24/7 SOC monitoring across all workstations and the two on-prem servers. Layered Microsoft Defender for Office 365 policies for phishing and impersonation protection. Rolled out quarterly phishing simulations and short training modules — the kind employees will actually finish.

Wave 3 — Network, backup, and documentation (week 4–6). Segmented the guest network off the production VLAN, replaced the aging firewall with a properly licensed next-gen unit, and stood up immutable, offsite backups with tested restores (not just "backups exist" — an actual restore drill). We then wrote the incident response plan, the acceptable use policy, and the vendor risk register the enterprise client had asked for.

TL;DR: Cybersecurity services in McMurray don't need to be exotic — they need to be the right controls, implemented in the right order, with evidence you can hand to an auditor or underwriter.

Outcomes

At the six-week mark:

• The insurance renewal went through at a lower premium than the prior year, because the carrier's controls-based discount now applied.
• The enterprise client's security questionnaire came back approved on first submission.
• Phishing simulation click-through dropped from a first-run rate in the low-30s to single digits by month three.
• Mean time to detect a suspicious login went from "whenever someone notices" to under 15 minutes, monitored by the SOC.

Just as important: the firm's leadership stopped losing weekend hours to security anxiety. The office manager got her actual job back.

Why local businesses choose PGH Networks

Buyers searching for cybersecurity services in McMurray usually have one of three drivers — an insurance renewal, a client-imposed security requirement, or an incident scare. We built our practice around all three.

A few things we do differently from the typical regional MSP:

• Framework-mapped work. Every control we implement is tagged to CIS, NIST CSF, HIPAA, or CMMC language, so when the auditor or underwriter asks, the answer is a document, not a shrug.
• On-the-ground presence. Engineers who can be in Peters Township, Canonsburg, Bethel Park, or Upper St. Clair the same day when something needs hands on hardware.
• AI-enablement, safely. We help clients adopt Copilot and other AI tools without leaking sensitive data — a growing part of what "cybersecurity" actually means in 2026.
• Right-sized. We serve 15-to-500-seat businesses. You won't be the smallest client we have, and we won't try to sell you an enterprise SIEM you don't need.

The takeaway for your business

If any part of that opening scenario sounded familiar — an insurance questionnaire you're dreading, a client asking for a SOC 2 letter you don't have, a suspicious login you can't fully explain — the path forward is the same one that firm took: assess against a real framework, remediate in waves, and generate the documentation as you go.

We offer a fixed-scope cybersecurity assessment for McMurray-area businesses that produces a prioritized roadmap, a gap analysis against your specific compliance or insurance drivers, and a fixed-price remediation quote. No pressure to bundle managed services on top unless it makes sense for you.
