Why Cybersecurity Matters for Your Business

As an accountant, you manage sensitive client information—tax records, payroll data, and financial reports. Cybercriminals know this, making accounting firms a top target for phishing scams, ransomware attacks, and data breaches. A single security lapse can lead to financial losses, legal trouble, and reputational damage. The good news? A cybersecurity checkup can help you catch risks before they become serious threats. This guide walks you through key areas to assess. If anything seems unclear or too time-consuming, an IT professional can conduct a full security audit for you.  

Your Cybersecurity Self-Check: 6 Key Areas to Review

Take a few minutes to evaluate your firm’s cybersecurity with this checklist:

1. Device Protection & Secure Access: Are Your Systems Properly Managed?

Why it’s important: Accounting firms rely on computers, laptops, and cloud applications to serve clients efficiently. If devices are unprotected, sensitive information could be at risk. How to check:
  • Ensure all office computers, laptops, and mobile devices are set up with secure access controls.
  • Confirm that software updates and security patches are applied regularly.
  • Check whether staff use strong passwords and multi-factor authentication (MFA) for logins.
💡 Tip: If you work remotely or store files in the cloud, secure access management is critical to prevent unauthorized entry into your systems.  

2. Data Backup & Recovery: Can You Restore Important Files If Needed?

Why it’s important: Unexpected data loss—due to accidental deletion, hardware failure, or technical issues—can disrupt your business. Regular backups ensure you never lose critical financial data. How to check:
  • Verify that your business files are backed up daily.
  • Ensure backups are stored in a secure, separate location (cloud or offsite storage).
  • Perform a test recovery to confirm that files can be restored quickly if needed.
💡 Tip: Backups should be automated and regularly checked—it’s not enough to assume they’re working.  

3. Microsoft 365 Backup: Are Your Emails & Documents Secure?

 Why it’s important: Many accounting firms use Microsoft 365 for emails, OneDrive, and SharePoint, but Microsoft does not provide built-in long-term backups. How to check:
  • Ask your IT team whether you have a separate backup for Microsoft 365 data.
  • Ensure backups retain deleted emails and files in case they need to be restored.
💡 Tip: Cloud-based collaboration is convenient, but having an independent backup solution adds an extra layer of security.  

4. Data Encryption: Is Confidential Client Information Properly Secured?

Why it’s important: If a laptop or USB drive is lost, unencrypted data could be accessed by unauthorized individuals. Encryption ensures that only authorized users can access sensitive files. How to check:
  • On Windows devices: Ensure BitLocker encryption is turned on.
  • On Mac devices: Confirm that FileVault encryption is enabled.
  • If staff use external storage (USB drives, external hard drives), check whether encryption is enabled for those devices as well.
💡 Tip: Encryption is a key compliance measure in protecting client data and meeting regulatory standards.  

5. Email Security: Are Your Communications Protected?

Why it’s important: Accountants regularly send and receive sensitive information via email. Ensuring secure email communications helps protect client data from being accessed or intercepted. How to check:
  • Use email encryption for sending confidential documents.
  • Enable Multi-Factor Authentication (MFA) for email accounts.
  • Ensure your email provider has security filtering to detect and block suspicious messages.
💡 Tip: Clients expect secure handling of their financial information. Email security measures protect both you and them.  

6. Ransomware Protection & File Security: Is Your Data Safe from Unauthorized Changes?

Why it’s important: Accounting firms rely on accurate and unaltered financial records. If files are accidentally or maliciously changed, your ability to serve clients is impacted. How to check:
  • Ensure your system monitors for unusual activity in client records and shared files.
  • Check if your business has file versioning enabled, so you can revert to previous versions of documents if needed.
  • Confirm that you have automated security alerts if unauthorized changes or file encryptions occur.
💡 Tip: Protecting financial data isn't just about keeping it safe—it’s also about ensuring that records remain accurate and trustworthy.
