Why CPAs Need Cyber Insurance

Accounting firms are among the most targeted businesses for cyberattacks. Here's why:

You store the most sensitive data possible — Social Security numbers, bank accounts, tax IDs, financial statements, payroll records
Tax season creates urgency — Phishing attacks spike 400% during January-April when CPAs are under deadline pressure
Wire fraud targeting — Business email compromise (BEC) attacks target CPAs because they handle client funds and financial transactions
Regulatory exposure — Data breaches trigger notification requirements under state laws, IRS regulations, and potentially GLBA
Small firms are prime targets — 43% of cyberattacks target small businesses, and CPA firms often lack enterprise-grade security

The average cost of a data breach for a small professional services firm is $120,000–$350,000 when you factor in notification costs, forensic investigation, legal defense, regulatory fines, and lost business. A $50-$200/mo cyber policy is cheap insurance against that exposure.

Cyber Insurance Pricing for CPA Firms

Firm Size	Monthly Cost	Annual Cost	Typical Limits
Solo CPA	$50–$100/mo	$600–$1,200/yr	$500K–$1M
Small firm (2-5 CPAs)	$100–$250/mo	$1,200–$3,000/yr	$1M
Mid-size firm (6-20 CPAs)	$250–$500/mo	$3,000–$6,000/yr	$1M–$3M
Large firm (20-50 CPAs)	$500–$750/mo	$6,000–$9,000/yr	$3M–$5M

What Cyber Insurance Covers for CPAs

First-Party Coverage (Your Direct Costs)

IRS Requirements & WISP Compliance

The IRS requires all tax professionals to have a Written Information Security Plan (WISP) under the Gramm-Leach-Bliley Act (GLBA) Safeguards Rule. While the IRS doesn't specifically require cyber insurance, having one demonstrates compliance with several WISP requirements:

What the IRS Requires

Designate a security coordinator — Someone responsible for your firm's data protection
Conduct a risk assessment — Identify where client data is stored and what threats exist
Implement safeguards — Technical, physical, and administrative protections
Monitor and test — Regular security testing and incident response procedures
Train employees — Annual cybersecurity awareness training

How Cyber Insurance Helps With WISP Compliance

Many cyber insurance carriers provide free tools that satisfy WISP requirements:

Risk assessments — Hartford and Chubb include free annual security assessments
Employee training — Most carriers offer free online training modules
Incident response plans — Carriers provide templates and guidance
Breach notification procedures — Built into the policy

Failing to comply with WISP requirements can result in IRS penalties and increased scrutiny. Having cyber insurance doesn't replace WISP compliance, but it provides many of the tools you need and a financial backstop if something goes wrong.

Cyber Insurance + E&O Bundles for CPAs

Most CPA firms should consider bundling cyber and E&O insurance. Here's why:

Why Bundle?

Coverage gap elimination — Standalone policies can leave gaps between E&O and cyber coverage. A client sues you for a data breach that exposed their financial data — is that a cyber claim or an E&O claim? Bundled policies eliminate the argument.
Cost savings — Expect 10-15% bundle discounts from most carriers.
Simplified claims — One carrier, one point of contact, no finger-pointing between policies.
Broader coverage — Bundled policies often include coverage enhancements not available in standalone products.

Bundle Pricing Comparison

Carrier	E&O Only	Cyber Only	Bundle Price	Savings
Hartford	$67/mo	$50/mo	$100/mo	15%
CNA	$85/mo	$75/mo	$136/mo	15%
Chubb	$125/mo	$120/mo	$208/mo	15%
Hiscox	$75/mo	$55/mo	$117/mo	10%
Travelers	$90/mo	$65/mo	$132/mo	15%

How to Reduce Your Cyber Insurance Premium

1. Implement Multi-Factor Authentication (MFA)

This is the number one premium reducer — and many carriers now require it. MFA on email, remote access, and cloud accounting software can reduce premiums 10-15%. Some carriers won't even quote you without it.

2. Use Endpoint Detection & Response (EDR)

Traditional antivirus isn't enough anymore. EDR tools like CrowdStrike, SentinelOne, or Microsoft Defender for Business actively monitor for threats. Having EDR can reduce premiums 5-10%.

3. Encrypt Everything

Encrypt laptops and desktops (BitLocker, FileVault)
Use encrypted email for client communications
Encrypt cloud storage
Encrypt backup systems

4. Regular Employee Training

Phishing is the #1 attack vector for CPA firms. Annual (or quarterly) security awareness training demonstrates to carriers that you're managing your biggest risk. Many carriers provide free training modules as part of the policy.

5. Maintain Offline Backups

The 3-2-1 backup rule: 3 copies of data, on 2 different media types, with 1 copy offline/offsite. Carriers love this because ransomware attacks become recovery exercises rather than ransom negotiations.

6. Have an Incident Response Plan

Document what happens when (not if) you have a breach. Who do you call? How do you contain it? Who notifies clients? Carriers view firms with documented IR plans as lower risk.

Real-World Cyber Claims for CPA Firms

Case 1: Tax Season Phishing — $185,000

A staff accountant clicked a phishing link during busy season. Attackers accessed the firm's tax software and filed 47 fraudulent returns using client SSNs. The cyber policy covered $85,000 in forensics, $60,000 in client notification and credit monitoring, and $40,000 in regulatory defense costs.

Case 2: Ransomware Attack — $275,000

A 12-person CPA firm was hit by ransomware two weeks before the April 15 deadline. All client files were encrypted. The cyber policy covered the $50,000 ransom payment (after the carrier's incident response team negotiated it down from $200,000), $75,000 in data recovery, $100,000 in business interruption losses, and $50,000 in extended deadline penalty coverage.

Case 3: Business Email Compromise — $320,000

Attackers compromised a partner's email account and sent fake wire instructions to three business clients. Total losses: $320,000. The social engineering coverage paid $250,000 (policy sublimit), and the E&O portion covered the remaining $70,000 in client claims.

Case 4: Cloud Software Breach — $150,000

A CPA firm's cloud accounting platform was breached, exposing 2,300 client records. Even though the breach was the vendor's fault, the CPA firm was responsible for notifying affected clients. The cyber policy covered $90,000 in notification costs and $60,000 in legal defense when three clients filed suit.

Cyber Insurance Application Tips for CPAs

Carriers ask detailed security questions. Here's how to prepare:

What They'll Ask

Do you have MFA enabled on email and remote access? (Required by most carriers)
What antivirus/EDR solution do you use? (Name the product)
Do you encrypt laptops and portable devices? (Yes/no — yes is better)
How often do you back up data? (Daily minimum, with offline copies)
Do you have an incident response plan? (Written plan preferred)
Do you conduct employee security training? (Annual minimum)
What cloud services do you use? (QuickBooks, Xero, Drake, ProConnect, etc.)
Have you had any cyber incidents in the past 3 years? (Be honest — lying voids coverage)
Do you have a WISP? (Required by IRS for tax preparers)
How many client records do you store? (Affects pricing)

Red Flags That Increase Premiums or Cause Declination

No MFA on email
No regular backups
Prior ransomware incident
Storing unencrypted SSNs on local machines
No employee training
Using end-of-life software

Cyber Insurance vs. E&O: What's the Difference?

Feature	E&O Insurance	Cyber Insurance
What it covers	Professional mistakes & negligence	Data breaches & cyber events
Trigger	Professional error or omission	Cyber event or data breach
Example	Tax filing error costs client $50K	Hacker steals 1,000 client SSNs
First-party costs	Limited	Extensive (forensics, notification, recovery)
Ransomware	Not covered	Covered
Business interruption	Not covered	Covered
Recommended?	Essential for all CPAs	Essential for all CPAs

Bottom line: You need both. E&O covers professional mistakes; cyber covers data breaches and cyber events. They protect against different risks, and neither fully covers what the other does.

Why Use a Brokerage Platform Instead of Buying Direct?

When a carrier offers instant quote-and-bind on their website, it's convenient — but you're only seeing one carrier's rates. A brokerage platform like Insura changes that equation:

One application, multiple quotes. Fill out one form and get compared across 10+ A-rated carriers including Hartford, Chubb, Hiscox, and more. No need to re-enter your business info on five different websites.
The price is the same — or lower. Carriers pay the broker's commission directly. Your premium is identical to what you'd pay buying direct, and often lower because a broker can find a carrier that prices your specific risk more competitively.
We work for you, not the carrier. A direct carrier's website is designed to sell you their policy. A brokerage platform is designed to find you the best policy — we have no incentive to push one carrier over another.
Automated comparison shopping, year after year. When your policy renews, a brokerage platform automatically re-shops your coverage across carriers to make sure you're still getting the best rate. Buy direct, and you're locked into one carrier's renewal pricing with no leverage.
Licensed experts when you need them. Have a coverage question or need help with a claim? You get access to real brokers — not a carrier's customer service line reading from a script.

Frequently Asked Questions

How much does cyber insurance cost for a solo CPA?

Basic cyber coverage for solo CPAs starts at $50/mo ($600/year) with $500K limits. If you handle more than 500 client records, expect $75-$100/mo.

Is cyber insurance required for CPAs?

Not legally required in most states, but the IRS requires a WISP, and many clients require proof of cyber coverage. It's effectively necessary for any CPA handling client data electronically.

Does my E&O policy include cyber coverage?

Some E&O policies include limited cyber coverage (usually $25,000-$50,000 in data breach response). This is rarely sufficient. A standalone cyber policy or comprehensive bundle is recommended.

What's the most common cyber claim for CPA firms?

Phishing attacks leading to tax fraud are the most frequent cyber claim for CPA firms, followed by ransomware attacks and business email compromise.

Should I get standalone cyber or bundle with E&O?

Bundle if your carrier offers it. You'll save 10-15% and eliminate coverage gaps between the two policies. Hartford, CNA, and Chubb all offer strong bundle options.

What cyber security measures reduce my premium most?

MFA is #1 (10-15% reduction), followed by EDR (5-10%), encryption (5%), employee training (5%), and documented incident response plans (3-5%).

How quickly can I get cyber coverage?

Most carriers can bind within 24-48 hours for standard CPA firms. Hartford and Hiscox offer same-day coverage for straightforward applications.

Does cyber insurance cover ransomware payments?

Yes, most policies cover ransom payments, though carriers strongly encourage not paying. The coverage also includes the forensic investigation, business interruption losses, and data recovery costs that typically far exceed the ransom itself.
