Will this satisfy IRS Pub 4557 and the FTC Safeguards Rule?

Yes — it's purpose-built for it. We deliver the WISP, the annual risk assessment, the qualified-individual designation, MFA enforcement, encryption, training, and the artifact file. If the IRS or FTC asks, you forward the evidence file we maintain. We don't represent you to regulators — your counsel does — but we give them what they need.

Our tax software is hosted (Rightworks / Cetrom). Don't they handle security?

They handle their hosted platform. They don't handle your identities, your endpoints, your M365 tenant, your email, your document portal, your bank logins, your staff training, or your WISP. Their security is one layer; you have six others — and Pub 4557 / FTC Safeguards apply to all of them.

What changes day one if we're not fully hardened yet?

MFA on every account (tax software included), EDR on every endpoint, immutable backups, and the wire-change verification procedure — the four controls that decide whether the next phishing email becomes a six-figure breach or a near-miss. Full hardening rolls out over 30–60 days; the survival controls go live week one.

What happens if we get an IRS data-theft notification?

We engage immediately: isolate affected endpoints, preserve evidence, coordinate the IRS Stakeholder Liaison report, draft client and AZ Attorney General notifications per A.R.S. §18-552 timelines, and work your insurer's breach counsel through the workflow. The IRP is written and tested — you're not learning the procedure during the event.

How fast do you respond to an after-hours incident?

15-minute response, 24/7, written in the SLA. Our SOC monitors EDR in real time, so most incidents trigger us before staff notice. For active phishing or ransomware events we're on a bridge with you within the SLA and on-site at the Mesa office within 25–40 minutes if needed.

Cybersecurity — Mesa Accounting Firms

Cybersecurity for Accounting Firms in Mesa, Arizona

Cybersecurity for a Mesa CPA firm isn't optional and it isn't 'antivirus plus a backup.' IRS Publication 4557 and the FTC Safeguards Rule require every paid preparer to have a written information security plan, a designated qualified individual, MFA on systems holding taxpayer data, encryption, monitoring, and a documented incident response procedure. Arizona A.R.S. §18-552 adds state breach-notification timelines. The Mesa firms we onboard usually have most of the technology and almost none of the documentation — which is exactly what gets you sanctioned, dropped by your carrier, or front-page in a client's group text after a breach.

We build a program that maps to NIST CSF and to the IRS / FTC / AICPA controls your malpractice carrier and your e-file privileges depend on — and we produce the evidence file. So when the IRS sends a data-theft notification, your insurer renews you, or a major client demands a security questionnaire, you're not scrambling, you're forwarding a PDF.

Why It Matters

Why Cybersecurity Matters for Accounting Firms in Mesa

IRS Pub 4557 is mandatory, not aspirational

Every paid preparer with an EFIN must have a written security plan and the controls Pub 4557 names. The IRS audits this. PTIN renewal now affirms it. A Mesa firm without a current WISP is one client complaint or one phish away from losing e-file privileges.

The FTC Safeguards Rule has been in force since 2023

CPA firms qualify as 'financial institutions' under GLBA. The revised Safeguards Rule requires a designated qualified individual, written risk assessment, MFA, encryption, access reviews, vendor oversight, and annual reporting to the firm's leadership — all things examiners and insurers now check.

Tax-season phishing targets the firm and the client

From January through April, phishing campaigns aimed at Mesa preparers spike — fake CCH password resets, fake IRS e-Services alerts, fake client wire-change requests. One click during a 14-hour day and the firm has a breach to disclose and a busy season to keep running.

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 deliver the stack and the attestation pack that gets you renewed without exclusions.

What's Included

Cybersecurity Scope for Mesa 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, board-ready, and the document the IRS and your insurer actually ask for.

Annual risk assessment + control evidence

Documented risk assessment covering every system touching taxpayer data — tax software, hosted environment, M365, document portal, payroll, AP — with prioritized remediation, owner, and evidence each control is operating.

MFA on the tax stack and everywhere else

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, quarterly access reviews — all documented.

Email security tuned for tax season

Advanced phishing protection, anti-impersonation (CEO/partner fraud), attachment sandboxing, external-sender banners, DMARC/DKIM/SPF enforcement, and a written wire-change verification procedure your staff actually follows.

Managed EDR with 24/7 SOC

Endpoint detection and response on every workstation, server, and laptop — ransomware rollback, behavioral detection, and isolation in minutes if a preparer opens a poisoned attachment at midnight in March.

Encryption, DLP, and 7216 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 for client data sharing.

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 your insurer and the IRS data-theft team will accept.

Written IRP + annual tabletop

Plain-English incident response plan with the IRS data-theft reporting workflow (Stakeholder Liaison, e-Services), AZ A.R.S. §18-552 timelines, client-notification templates, and an annual leadership tabletop so the IRP isn't read for the first time during an incident.
