What IT Security Requirements Do Accounting Firms in New Jersey Need to Meet?

Accounting firms in New Jersey face higher-than-average cybersecurity expectations because they handle tax records, financial statements, and sensitive personal information. While there is no single “CPA cybersecurity law,” most accounting firms are expected to implement 5–7 core cybersecurity services for accounting firms to meet regulatory expectations, client requirements, and practical risk management standards.

For accounting firms, IT security is not just about compliance—it’s about protecting client trust, meeting deadlines, and preventing business-ending disruptions, especially during peak tax seasons.

Why Accounting Firms Are High-Value Targets for Cyberattacks

Accounting firms are attractive targets because they store:

• Personally identifiable information (PII)
• Tax returns and supporting documents
• Bank account and financial data
• Client credentials and payroll information

Cybercriminals know that accounting firms operate under strict deadlines, making them more likely to pay ransoms or rush recovery efforts. This is why generic security setups that might work for other small businesses often fall short for CPA firms.

Core IT Security Controls Accounting Firms Should Have in Place

Most accounting firms should have at least 5–7 foundational security controls in place to reduce risk and meet common expectations:

Multi-Factor Authentication (MFA)

Required for email, cloud applications, and remote access to prevent credential-based attacks.

Endpoint Detection and Response (EDR)

Advanced protection for desktops, laptops, and servers that goes beyond basic antivirus.

Email Security and Phishing Protection

Critical for preventing invoice fraud, credential theft, and malicious attachments.

Secure Backup and Disaster Recovery

Secure backup and disaster recovery should include encrypted backups with both onsite and offsite copies, tested regularly.

Patch and Update Management

Ensuring operating systems and applications are kept current to reduce vulnerabilities.

Secure Remote Access

Encrypted VPN or secure cloud access for remote workers and on-premises staff.

Monitoring and Alerting

Continuous monitoring to detect issues before they impact firm operations.

These controls form the baseline of a practical security posture for accounting firms.

The FTC Safeguards Rule and What It Means in Practice

Many accounting firms are subject to the FTC Safeguards Rule, which requires firms to implement “reasonable” security measures to protect client data.

In practical terms, this means:

• Documented security policies
• Risk assessments
• Access controls
• Ongoing monitoring and oversight

While the rule does not prescribe specific technologies, firms are expected to demonstrate that they have taken reasonable steps to protect client information based on their size, data sensitivity, and risk exposure.

Common Security Gaps Seen in Accounting Firms

Through years of working with CPA firms, several patterns show up repeatedly:

• Relying solely on basic antivirus software
• Inconsistent use of MFA across systems
• Backups that exist but are never tested
• No documented incident response plan
• Generic IT providers unfamiliar with accounting workflows

These gaps often remain hidden until a phishing incident, ransomware attack, or client security questionnaire exposes them.

How an Accounting-Focused MSP Reduces Security Risk

An MSP that specializes in accounting firms brings a different approach to managed IT services and security:

• Proactive monitoring instead of reactive fixes
• Security controls designed around tax-season pressure
• Ongoing reviews and adjustments as threats evolve
• Clear documentation to support audits and client inquiries

This approach aligns security with how accounting firms actually operate, rather than applying a one-size-fits-all model.

Real-World Perspective from Inside a Regional Accounting Firm

Total Cover IT Founder David Quick spent 17 years as the internal IT Director for a mid-sized regional accounting firm in New Jersey, supporting the firm as it grew from approximately 50 employees to more than 80.

During that time, David was responsible for:

• Designing, implementing, and maintaining the firm’s entire IT infrastructure
• Supporting specialized practice management and time and billing systems, workflow management tools, and various accounting, audit, and tax-related applications
• Minimizing downtime, especially during peak tax seasons
• Leading a full headquarters office relocation, including the migration and reassembly of core IT infrastructure, with minimal disruption

That experience created a deep, first-hand understanding of how security failures and technology gaps impact accounting firms under real deadline pressure—not theory, but day-to-day operations inside a CPA firm.

How to Think About IT Security as an Accounting Firm Owner

Instead of asking, “Are we compliant?” accounting firm leaders should ask:

• Are we protecting client data at the level clients expect?
• How quickly could we recover from a security incident?
• Would a security failure disrupt tax deadlines?
• Does our IT provider truly understand CPA firm workflows?

Security done right supports reliability, trust, and long-term firm stability.

FAQ

What cybersecurity controls should most accounting firms have in place?

Most accounting firms should have core protections such as MFA, endpoint detection and response, email security, secure backups, patch management, secure remote access, and continuous monitoring.

Are accounting firms required to follow a specific cybersecurity law?

There is no single CPA-specific cybersecurity law, but many firms are expected to implement reasonable safeguards based on the sensitivity of the data they handle, client expectations, and applicable regulations such as the FTC Safeguards Rule.

Why are accounting firms targeted by cybercriminals?

Accounting firms store highly valuable data including tax returns, personal information, payroll records, and financial documents. Attackers also know firms work under deadline pressure, which can make disruptions more costly and urgent.

How can an accounting-focused MSP improve security?

An accounting-focused MSP can build security around tax-season realities, support accounting-specific workflows, improve monitoring and documentation, and reduce the risk of downtime or client data exposure.
