PGH Networks is a Pittsburgh-based managed services provider that delivers IT, cybersecurity, and cloud for Pittsburgh CPA firms and accounting practices across Allegheny, Washington, Butler, Westmoreland, and Beaver counties. If you run a tax and assurance practice in the region and you are evaluating an MSP that actually understands CCH Axcess, ProSystem fx, Lacerte, UltraTax, QuickBooks, Sage Intacct, and ShareFile alongside the IRS Publication 4557 WISP, GLBA Safeguards Rule, and FTC Safeguards Rule obligations that govern your data, this page is written for you.
The decision is not really "who has the cheapest help desk." It is "who can keep our firm operating through busy season, prove to the IRS and our clients that taxpayer data is protected, and host our tax and accounting stack so partners and staff can work from a client site, a home office, or our Downtown or South Hills suite without friction."
Why this matters for a Pittsburgh CPA firm
Accounting firms hold exactly the data attackers want: Social Security numbers, K-1s, bank credentials, payroll files, and signed 8879s. The IRS now expects every paid preparer to maintain a written information security plan under Publication 4557 and the Gramm-Leach-Bliley Safeguards Rule, and the amended FTC Safeguards Rule requires a designated qualified individual, documented risk assessments, MFA, encryption, and a 30-day breach notification process. Peer review, professional liability carriers, and increasingly your own enterprise clients will ask for evidence that these controls exist and are tested.
Add the operational reality — 70-hour weeks from late January through April 15, October extension crunch, year-end 1099 and payroll cycles — and the cost of an outage or ransomware event during filing season is not theoretical. A CPA firm cannot tell clients "we'll be back online in a week."
A CPA firm's MSP is not just an IT vendor; it is a control owner named in your WISP and your FTC Safeguards documentation.
Where most providers fall short on CPA-firm IT, cybersecurity, and cloud
Most accounting firms in the Pittsburgh market end up choosing among four kinds of providers, and each leaves a gap.
National MSPs without local presence can produce slick compliance decks and 24/7 SOC coverage, but the technician who actually shows up when a Citrix session won't launch on April 14 is a rotating ticket queue two time zones away. They rarely know your tax software vendors by name, and onboarding a new staff accountant before busy season turns into a ticket war.
Generalist local IT shops answer the phone and know the building, but they treat a CPA firm like any other 40-seat office. There is no documented WISP, no mapping of controls to FTC Safeguards 314.4(c), no hardened configuration baseline for tax workstations, and no plan for what happens when CCH Axcess, ProSystem fx Engagement, or a hosted QuickBooks environment misbehaves at 9 p.m. on a Sunday in March.
Tax-software hosting resellers solve one slice — they will host your application stack — but they are not your MSP. They do not manage your endpoints, your Microsoft 365 tenant, your identity platform, your firewalls at the office, your phones, or your security awareness training. You end up integrating three vendors yourself and hoping the seams hold during an incident.
In-house IT stretched thin by audit prep is the most common pattern at firms above roughly 25 staff. One or two internal technologists keep the lights on but cannot simultaneously run a SOC 2-grade security program, evaluate AI tools, document a WISP, and stand up Conditional Access policies that survive an IRS or insurance questionnaire.
What to look for instead in an MSP for a Pittsburgh CPA firm
A short, honest checklist for evaluating IT, cybersecurity, and cloud for Pittsburgh CPA firms:
The provider should name the tax and accounting applications they actually support — CCH Axcess, ProSystem fx, UltraTax, Lacerte, Drake, QuickBooks Desktop and Online, Sage Intacct, ShareFile, SafeSend — and describe how they handle hosting, updates, and year-rollover for them. They should produce, not just reference, a written information security plan aligned to IRS Pub 4557 and the FTC Safeguards Rule, with a designated qualified individual willing to be named. They should run identity-first security: Microsoft 365 or Google Workspace hardened with MFA, Conditional Access, privileged access controls, and managed EDR with 24/7 monitoring. They should offer a clear cloud strategy — private hosted desktops, Azure Virtual Desktop, or properly secured on-prem — rather than one default. And they should publish a busy-season SLA that reflects January through April reality, not a generic 8-to-5 response window.
TL;DR: The right MSP for a Pittsburgh accounting firm proves tax-software fluency, owns named compliance controls, and shows up locally during busy season — not just on paper.
How this maps to our approach at PGH Networks
PGH Networks is built for exactly this profile of buyer. We are headquartered in the Pittsburgh metro, our engineers are local, and our CPA-firm clients get a documented WISP package mapped to IRS Publication 4557, GLBA, and the FTC Safeguards Rule, including the qualified-individual designation, annual risk assessment, incident response runbook, and vendor-management register that examiners and insurers ask to see.
On the application side, we support the working stack of a modern accounting practice: CCH Axcess and ProSystem fx (including Engagement and Document), UltraTax, Lacerte, Drake, QuickBooks, Sage Intacct, ShareFile, and SafeSend Returns. We host where hosting makes sense — Azure Virtual Desktop or private cloud — and we leave applications on-prem when latency or licensing makes that the better answer. Either way, the endpoints, the Microsoft 365 tenant, identity, email security, EDR, backup with immutable copies, and the firewall at your office are managed under one accountable provider.
Our cybersecurity baseline for CPA clients includes managed detection and response, phishing-resistant MFA, Conditional Access tuned to firm roles (partner, manager, senior, intern, seasonal), encrypted laptops, DNS filtering, dark-web credential monitoring, and quarterly tabletop exercises. Our growing AI-enablement practice helps firms adopt Microsoft Copilot and document-automation tools without leaking client data into public models — a question every managing partner is now being asked by staff and clients alike.
PGH Networks is the Pittsburgh MSP for accounting firms that need their tax stack hosted, their WISP documented, and their phones answered locally on April 15.
And because we are a Pittsburgh firm serving Pittsburgh firms, the same engineer who set up your environment is the one who answers when a partner can't e-file at 11 p.m. on the filing deadline.
