Cybersecurity Services for CPA and Accounting Firms That Protect Client Data

Cybersecurity services for accounting firms are specialized security controls, monitoring, and incident response built to protect sensitive client data (tax returns, financial records, and PII) and support regulatory obligations like the FTC Safeguards Rule and IRS Publication 4557. Unlike generic IT security, they are shaped around how accounting firms actually work: client portals, remote teams, multi-office structures, and peak-season deadlines.

Accounting firms are high-value targets because they hold concentrated, sensitive financial data for many clients in one place. Industry reporting points to billions in fraud losses tied to compromised tax preparers, along with a sharp rise in tax-season phishing and business email compromise (BEC). A single breach can expose hundreds of client records at once, which is why attackers time campaigns around busy season.

The FTC Safeguards Rule requires financial institutions, including many tax and accounting firms, to maintain a documented information security program that protects customer data. Most firms that prepare returns or handle client financials fall under it. MYCPE ONE's plans include controls and documentation that support alignment with the Rule, rather than bolting compliance on after the fact.

IRS Publication 4557 outlines the data security responsibilities of tax professionals, and a Written Information Security Plan (WISP) is the documented plan the IRS expects every preparer to maintain. Both are standard considerations in MYCPE ONE's approach, with WISP documentation and IRS Publication 4557 alignment built into every plan.

The Compliance Plan is a security foundation: core controls, endpoint protection, compliance alignment support, and documentation readiness. The Managed Plan adds 24×7 active monitoring, sub-1-hour response times, and full threat response on top of everything in the Compliance Plan. Firms wanting deeper, around-the-clock coverage typically choose the Managed Plan.

Managed cybersecurity services for mid-sized firms include 24×7 SOC monitoring, endpoint and server protection, rapid incident response, continuous threat detection, compliance documentation support, and security awareness training. For mid-sized and multi-office firms, MYCPE ONE also offers custom SLA design and scoping for cloud-heavy environments and frameworks like SOC 2 and ISO 27001.

MYCPE ONE uses predictable, per-endpoint pricing with no hidden fees for incident response, report generation, or compliance documentation. Actual cost depends on firm size, number of endpoints, and the plan you choose. Custom proposals are available for multi-office or complex environments, typically delivered within 24 hours of sharing your requirements.

Yes. The Managed Plan includes 24×7×365 monitoring from a Security Operations Center staffed by certified analysts (not automated scripts), with a managed security response time of under one hour. Incident response covering containment, forensics, and recovery support is included in the retainer, so there are no additional per-incident fees.

Yes. MYCPE ONE supports multi-office firms, cloud-heavy setups, and custom compliance scoping such as SOC 2 and ISO 27001. For needs outside the standard plans, the team builds a tailored protection approach with custom SLAs based on your firm's size, structure, and infrastructure.

Yes. MYCPE ONE delivers cybersecurity services fully remotely across the US, Canada, and the UK, with awareness of frameworks including FTC Safeguards, GLBA, GDPR, and PIPEDA. Remote delivery means firms get the same monitoring and support regardless of office location.

No. Cybersecurity services focus on protecting your firm from threats through monitoring, threat detection, incident response, and compliance support. Managed IT services cover day-to-day needs like helpdesk, endpoint management, and tax-season readiness. Many firms need both, and MYCPE ONE offers Managed IT Services as a separate, complementary offering.
