Pittsburgh CPA Firm Cybersecurity and Cloud: A Walkthrough

This is an illustrative example, not a client story. The business described below is hypothetical, built to show how this kind of project typically runs. Nothing here is a measured result from PGH Networks' work for a specific company.

PGH Networks is a Pittsburgh-based managed services provider that delivers cybersecurity, cloud, and compliance support to accounting firms across the metro, and this Pittsburgh CPA firm cybersecurity and cloud walkthrough shows how a project with a mid-sized public accounting practice headquartered in the South Hills would typically run. Picture a firm heading into the fall with two overlapping problems: a written information security program (WISP) that has not been updated to reflect current IRS Publication 4557 expectations, and a tax software stack still tethered to an aging on-premises server that cannot survive another April.

The technical shape of the project is laid out below so other Pittsburgh-area partners and firm administrators can judge fit.

The buyer scenario: a 38-person Pittsburgh CPA firm

The firm employs 38 people across offices in Pittsburgh and Washington County, prepares roughly 1,900 individual returns and about 210 business returns a year, and runs CCH Axcess and Lacerte alongside QuickBooks Online, a document management platform, and a hosted portal for client deliverables. Two partners have recently received cyber-insurance renewal questionnaires demanding evidence of MFA on email and remote access, endpoint detection and response, encrypted backups, and a documented incident response plan. None of it is formalized.

A CPA firm without a current WISP is not just out of compliance, it is uninsurable at renewal.

The challenge: GLBA, IRS WISP, and a tax-season deadline

Three constraints define the project. First, the Gramm-Leach-Bliley Act Safeguards Rule and the IRS WISP requirement for paid preparers both demand a written, tested security program naming a qualified individual, risk assessments, and vendor oversight. Second, CCH Axcess and Lacerte performance has degraded on the local server to the point that partners log in from home over a VPN just to escape daytime slowness. Third, the go-live has to happen before January 15, because no partner will authorize a cutover during tax season.

Layered on top: the firm's existing IT vendor is a generalist break-fix shop with no accounting vertical experience, no familiarity with tax-software hosting, and no compliance documentation practice. The partners want a provider that speaks both CPA and NIST.

How PGH Networks would solve it

We would structure the project in three parallel tracks so the January deadline is achievable.

Security baseline and WISP. Our professional services team leads a two-week risk assessment mapped to the FTC Safeguards Rule and IRS Publication 4557, then drafts the WISP naming the firm's IT partner as qualified individual, cataloguing systems that touch taxpayer data, and defining incident response roles. In parallel, our cybersecurity team deploys managed EDR to every endpoint, enforces conditional-access MFA on Microsoft 365, rebuilds the firm's email security posture, and rolls out an encrypted, immutable backup target with 90-day retention.

TL;DR: The project pairs a GLBA-aligned WISP with a CCH and Lacerte cloud migration so a firm like this can clear its insurance questionnaire and enter tax season on modern infrastructure.

Cloud migration for tax software. CCH Axcess is already SaaS, so the work there is identity, data-loss prevention through Microsoft 365 and Microsoft Purview, and disciplined offboarding. Lacerte moves to an authorized hosting environment sized for the firm's concurrent-user count, with the local file server retired to a read-only archive. QuickBooks desktop files for a handful of write-up clients migrate to a hosted profile keyed to the same identity provider so partners have a single sign-on across every tax and accounting application.

Operational handoff. Managed IT takes over patch management, RMM, and help desk with a documented tax-season support plan: priority handling of partner-impacting incidents through the filing season, and a named on-call engineer familiar with the firm's stack. We would also stand up an AI readiness assessment and an acceptable-use policy so the firm can evaluate Copilot for research and drafting without exposing client data.

What a firm like this can expect: uptime, audit posture, and partner sign-off

With the cutover landing ahead of the partner-imposed deadline, a firm like this can expect tax season to play out differently from the year before.

The hosted Lacerte environment stays up through the filing deadline without partner-impacting incidents that last long enough to notice. CCH Axcess logins stop being a coffee break. The cyber-insurance renewal goes through without follow-up questions, because the carrier gets the WISP, EDR attestation, and MFA evidence it asked for. And when a bank sends over a third-party risk questionnaire, the managing partner answers it from the WISP and vendor list instead of scrambling.

Perhaps most important: no partner has to call anyone at 6:30 a.m. during tax season. That is the metric CPA firms actually judge an MSP on.

Takeaway for other Pittsburgh accounting firms

Most Pittsburgh CPA firms in the 15-to-75-person range are sitting on the same three-part problem as the firm in this scenario: a WISP that exists only in theory, tax software running on hardware that is one bad Saturday away from a disaster, and cyber-insurance questionnaires that keep getting stricter. The playbook in this Pittsburgh CPA firm cybersecurity and cloud walkthrough is repeatable, and the sequencing matters. The WISP and identity work has to lead, because it drives both the insurance answer and the migration design. The cloud move follows, because once identity and endpoint controls are trustworthy, hosting CCH, Lacerte, or ProSystem fx in a compliant environment is straightforward. Ongoing managed IT and a real tax-season SLA close the loop.

Firms exploring document automation or an internal custom AI application for engagement letters, PBC list handling, or 1040 organizer intake can layer that on once the compliance floor is in place, not before.
