Modern Identity, Azure Virtual Desktop, and Tax-Season-Ready IT Built for an 8-Person Inland Empire CPA Firm

How Legacy Accounting Tax replaced an aging on-premise server, deployed Microsoft 365 Business Premium with location-based Conditional Access, and stood up Azure Virtual Desktop — so staff can work tax season from anywhere without losing the MSSQL accounting platform they rely on.

About the client

An 8-person Inland Empire CPA firm preparing taxes, doing the books, and protecting client financial data — year-round.

Legacy Accounting Tax is a CPA and tax-preparation firm based in Rancho Cucamonga, California, serving individuals and small-to-medium businesses across the Inland Empire and Southern California. The firm operates from a single office on Laurel Street under the industry-appropriate legacyaccounting.tax domain, with a tight 8-person team handling tax preparation, bookkeeping, and accounting services for a steady book of business and personal clients.

Accounting practices handle Social Security numbers, financial statements, and tax filings every day — a high-value, high-compliance environment that demands above-average security and uptime. As Legacy Accounting Tax grew, the firm came to Soaring Towers for managed IT that could deliver enterprise-grade identity security, Azure cloud infrastructure that preserved the MSSQL accounting platform, and the kind of tax-season resilience an 8-person team can't build alone.

The challenge

An 8-person CPA firm running tax season on a 7-year-old out-of-warranty server, consumer workstations, and zero identity monitoring.

MBSServer — a Dell PowerEdge T330 hosting the firm's MSSQL accounting database — was on Windows Server 2016 Essentials with a Dell warranty that expired in January 2020. Workstations were out-of-warranty Dell Vostros. No MFA enforcement. No Conditional Access. No domain monitoring. The same pattern we see across small CPA firms that grew faster than their IT did.

  • Aging on-premise server hosting the firm's MSSQL accounting database
    A Dell PowerEdge T330 running Windows Server 2016 Essentials, Dell warranty expired January 2020, and MSSQL — the database the entire practice depends on — running on hardware 3+ years out of vendor support at the time of engagement.
  • Out-of-warranty consumer workstations with no remote patching
    Multiple Dell Vostro 3888 desktops with warranties expired October 2022 running Windows 11 — updates applied by hand visit-by-visit, no remote endpoint management, no fleet patching cadence.
  • No cloud identity layer or sign-in monitoring
    No MFA enforcement, no Conditional Access, no location-based sign-in monitoring — and an accounting firm holding client SSNs and tax data is one of the highest-value targets in the SMB attack surface.
  • No domain lifecycle monitoring or cloud backup posture
    Backup was two local Synology NAS units with no monitored cloud destination, and the firm's domain registrar payment method had expired — putting the legacyaccounting.tax domain at risk of dropping during tax season, when email outage equals lost revenue.
The solution

Microsoft 365 Business Premium, a governed Azure cloud, and identity security usually reserved for enterprise banks.

Soaring Towers designed and is operating an end-to-end managed environment for Legacy Accounting Tax — a 6-Premium + 2-Standard Microsoft 365 tenant, an Azure Virtual Desktop deployment that preserves the MSSQL accounting platform, Entra ID Conditional Access with location-based sign-in policies, and lifecycle monitoring on the domain that kept email available through every tax season since.

1
Microsoft 365 modernization & license architecture
Phased Microsoft 365 deployment — from Business Standard at onboarding (2023), through Basic, into a 6-seat Business Premium tenant + 2 Standard seats (2024), with enterprise security (Defender for Business, Intune, Conditional Access, Entra ID P1) right-sized to the firm's maturity.
2
Azure Virtual Desktop & cloud database
Azure Plan, Azure Virtual Desktop session host ("LegacyPCAVD-3"), and a Windows Server 2025 Datacenter Azure-hosted database — staff access the MSSQL accounting platform from anywhere, with no forced vendor migration of the line-of-business software.
3
Entra ID Conditional Access & location-based sign-in monitoring
Cloud-only Entra ID with Conditional Access policies that flag and block unusual sign-ins by location — 6+ alerts generated and investigated through Soaring Towers' security protocol, with zero confirmed breaches across the lifetime of the engagement.
4
Domain & user lifecycle operations
CIPP-driven user onboarding/offboarding, CWRMM remote patch management on endpoints, and proactive domain lifecycle monitoring — including a domain-registrar near-miss caught before legacyaccounting.tax could lapse.
Why managed IT matters

Today's accounting and tax firms need IT that protects client data, survives tax season, and looks like enterprise from the outside.

An 8-person CPA firm processing tax returns, financial records, and client SSNs — accessed by staff working extended hours during the January-to-April crunch — can't operate on aging hardware and unmonitored cloud accounts. The threat model is real: accounting firms are high-value targets, and a single compromised mailbox or expired domain can pull email offline during the worst possible week of the year.

At Soaring Towers, we specialize in managed IT for accounting and professional-services firms — bringing the enterprise-grade identity, cloud infrastructure, and proactive monitoring of a much larger operation, sized for a sub-10-person practice.

The technology stack we deployed

Four foundations of a modern accounting-firm IT environment.

Every layer below was selected and configured specifically for the realities of an 8-person CPA practice — secure access to financial data, an MSSQL accounting platform that staff can't migrate away from, and a January-to-April crunch that no piece of infrastructure is allowed to fail during.

Productivity & security

Microsoft 365 Business Premium + Standard

Six Microsoft 365 Business Premium seats — Exchange Online, Teams, SharePoint, OneDrive, Defender for Business, Intune, and Entra ID P1 — plus two Business Standard seats, with license tiers right-sized seat-by-seat and phased in over 15 months rather than sold all at once.

  • 6 Business Premium + 2 Standard seats
  • Microsoft Defender for Business EDR
  • Intune-managed endpoints
Cloud infrastructure

Microsoft Azure + Azure Virtual Desktop

Microsoft Azure Plan since July 2024, an Azure Virtual Desktop session host (LegacyPCAVD-3, Windows 11 Enterprise multi-session) for staff access, and a Windows Server 2025 Azure-hosted database VM — preserving the MSSQL accounting workload while moving the compute to the cloud.

  • Azure Virtual Desktop session host
  • Windows Server 2025 Azure database VM
  • MSSQL accounting workload preserved
Identity & sign-in

Entra ID + Conditional Access with location policies

Cloud-only Entra ID (no AD Connect, no on-premise domain sync to manage) with Conditional Access policies that flag and block unusual sign-ins by location — the same identity architecture enterprise financial-services firms deploy, configured for a sub-10-person practice.

  • Cloud-only Entra ID (no AD Connect)
  • Location-based Conditional Access
  • Mailbox-rule audits on sign-in alerts
Patch & lifecycle management

CWRMM + CIPP + domain monitoring

CWRMM for remote endpoint patching (Windows + Dell BIOS updates), CIPP-driven user onboarding and offboarding against the M365 tenant, and proactive domain registrar lifecycle monitoring — including PwPusher-encrypted credential handoffs for sensitive operations.

  • CWRMM remote patch management
  • CIPP user lifecycle workflows
  • Domain registrar lifecycle monitoring

Frequently asked questions

Answers for accounting and tax-firm leaders.

Don't see your question? Reach out for a discovery call.

What does managed IT look like for a CPA or tax-preparation firm?

It includes Microsoft 365 with Business Premium for sensitive-data users (Exchange, Defender for Business, Intune, Entra ID P1), Conditional Access with location-based sign-in monitoring, Azure cloud infrastructure that preserves the accounting platform (often MSSQL-backed), CWRMM remote patching, CIPP-driven user lifecycle, proactive domain lifecycle monitoring, and a structured security escalation protocol for sign-in incidents.

CPA firms hold client SSNs, financial statements, and tax filings — extremely high-value data for attackers. A single compromised mailbox can expose dozens of clients and trigger a real breach-notification event. Entra ID Conditional Access with location-based sign-in policies catches anomalous logins before they reach mailbox data, and a structured response protocol (sign-in log review and mailbox-rule audits) closes the loop on every alert.

Yes. We deploy Azure Virtual Desktop and Azure-hosted database VMs so staff access the same line-of-business accounting platform (often MSSQL-backed) remotely — modern compute and identity layer wrapped around the software your team already knows. Vendor migration is not required, which avoids retraining, data-conversion risk, and tax-season disruption.

Real experience deploying Entra ID Conditional Access and Microsoft 365 Business Premium for sensitive-data firms, comfort operating Azure Virtual Desktop with line-of-business applications like MSSQL accounting platforms, willingness to phase license tiers up over time instead of overselling at onboarding, proactive lifecycle monitoring (domain, license, identity), a documented security escalation protocol, and a strategic review cadence that helps you plan IT decisions ahead of every tax season — not just respond to tickets.
