Cybersecurity for Accounting Firms in Tempe, Arizona
The typical Tempe CPA firm we assess has commercial antivirus, a cloud backup, and a partner who's skimmed the IRS Pub 4557 checklist — and almost none of the written documentation, MFA enforcement, or vendor risk inventory the FTC Safeguards Rule and Pub 4557 actually require. That gap is what gets an EFIN suspended after a data-theft incident, a cyber-insurance policy non-renewed at midnight, or a Skysong SaaS client walking down the street because your security questionnaire came back with more question marks than checkmarks.
We build a cybersecurity program for Tempe accounting firms that maps to NIST CSF, IRS Pub 4557, the FTC Safeguards Rule, GLBA, and Arizona A.R.S. §18-552 — and we produce the evidence file. WISP, risk assessment, MFA enforced on the whole tax stack, EDR with 24/7 SOC, immutable backups with tested restores, a written IRS data-theft response plan, and quarterly tabletops. When the IRS Stakeholder Liaison, your insurer, or a startup client's infosec team asks for proof, you forward a folder instead of scrambling.
Why It Matters
Why Cybersecurity Matters for Accounting Firms in Tempe
IRS Pub 4557 isn't optional and PTIN renewal asks about it
Every paid preparer with an EFIN has to have a written information security plan and the safeguards Pub 4557 names. The IRS audits it. PTIN renewal now affirms it. A Tempe firm without a current WISP is one phish or one client complaint from losing e-file privileges mid-season.
The FTC Safeguards Rule has been in force since 2023
CPA firms are 'financial institutions' under GLBA. The revised rule requires a designated qualified individual, a written risk assessment, MFA, encryption, access reviews, vendor oversight, and reporting — the exact controls examiners and insurers now demand as a condition of doing business.
Startup and SaaS clients run real security reviews on you
ASU-adjacent and Rio Salado-based SaaS clients push CAIQ-style questionnaires at their CPA firm before engagement. Without documented MFA, EDR, encryption, IR, and vendor oversight, you either fail the review or you promise controls you don't have — both are bad outcomes.
Cyber-insurance renewals now demand documented controls
Carriers are exiting the CPA segment or requiring MFA on every account, EDR with 24/7 monitoring, immutable backups, segmented networks, and tested IR plans before they'll quote. We build the stack and hand you the attestation pack.
What's Included
Cybersecurity Scope for Tempe Accounting Firms
Written Information Security Plan (WISP)
A WISP mapped to IRS Pub 4557, the FTC Safeguards Rule, GLBA, AICPA SOC 2 controls, and Arizona A.R.S. §18-552 — reviewed annually and the document the IRS, your insurer, and your startup clients' security teams actually ask for.
Annual risk assessment with evidence file
Documented risk assessment covering every system touching taxpayer data — tax software, hosted environment, M365, document portal, payroll, AP — with prioritized remediation, owner, and proof each control is operating.
MFA on the entire tax stack
Enforced MFA on CCH Axcess / UltraTax / Lacerte / Drake, the hosted environment, M365, the document portal, QuickBooks, and the firm's bank logins. Number-matching, conditional access, and quarterly access reviews — all documented.
Email security tuned for tax season
Advanced phishing protection, anti-impersonation (partner / managing-partner fraud), attachment sandboxing, external-sender banners, DMARC / DKIM / SPF enforcement, and a written wire-change verification procedure staff actually follow.
Managed EDR with 24/7 SOC
Endpoint detection and response on every workstation, server, and laptop — ransomware rollback, behavioral detection, and isolation in minutes when a preparer opens a poisoned attachment at midnight in March.
Encryption, DLP, and 7216 disclosure controls
Full-disk encryption, encrypted email for client deliverables, DLP rules that catch SSNs and EINs leaving the firm without authorization, and IRC §7216 disclosure consent workflows integrated with your engagement tools.
Immutable backups + quarterly tested restores
Encrypted, immutable 90-day backups of M365, tax data, QuickBooks files, document portal, and file shares — with written restore logs the IRS data-theft team and your insurer will actually accept.
Written IRP + annual tabletop
Plain-English incident response plan with the IRS data-theft workflow (Stakeholder Liaison, e-Services), Arizona A.R.S. §18-552 timelines, client-notification templates, and an annual leadership tabletop we run with your partners.
