Cybersecurity threats now include phishing, ransomware and AI-driven social engineering. Accounting firms handle highly sensitive financial data, making them prime targets for cyberattacks. Despite beliefs that small firms aren’t at risk, hackers often target them because their client information may not be as secure.

To stay secure, firms must adopt comprehensive strategies that cover software, staff training, authentication, vendor management, and data protection. While cybersecurity safeguards might not always be top of mind for accountants, they could significantly impact your reputation. Here are six tips to help accountants stay alert against the threat of cyberattacks.

One of the most common ways cybercriminals can exploit accountants and small businesses is via outdated software. This is why it’s essential to have your accounting software, operating systems and antivirus programs updated regularly with the latest security patches. These patches fix vulnerabilities before attackers can take advantage of them. Delaying updates gives cybercriminals more time to target your company's weaknesses.

Updating your software might seem less important during the crunch of tax season, but it could leave you vulnerable. Instead of doing manual updates, enable automatic updates on your applications whenever possible. This makes sure you get security patches right away without having to update manually. Also, it’s important to monitor vendor announcements for critical security updates. Some patches require immediate attention due to severe security risks.

Although phishing has existed for decades, it still makes up 90 per cent of data breaches. Accounting firms naturally deal with sensitive data, making them prime targets for cybercriminals.

Implement regular training sessions to teach employees how to spot suspicious emails. Emphasize common phishing signs such as urgent language, dubious sender addresses and requests for sensitive details. For large transaction requests, consider establishing a rule that these must be verified in person.

It’s also smart to establish a formal reporting process whenever an employee suspects a phishing attempt. This helps you identify any new methods cybercriminals are using to try to bypass existing security measures.

In this era, multi-factor authentication (MFA) should be a given since it provides an extra layer of security. Any account that holds financial data, client details or system access credentials must have MFA enabled.

Choose authentication methods that fit your workflow. Options include authenticator apps, SMS codes, hardware tokens or biometric verification. For instance, if you’re a digital nomad, using an authenticator app is probably more convenient than SMS codes. In any case, set MFA requirements for all team members with access to sensitive systems to ensure consistency.

As AI cloning technology advances, voice verification systems are becoming obsolete. Fraudsters can now produce convincing voice replicas using brief audio samples from voicemail greetings, social media or recorded calls.

Before sharing any sensitive information over the phone, you might want to set up MFA to verify they are who they claim to be. This extra step will help ensure you’re speaking to the correct person.

Be sure to confirm unusual requests via alternative communication methods. If a client calls requesting urgent wire transfers or account changes, contact them directly using a known phone number before proceeding.

Train your team to identify potential voice and video manipulation (“vishing”). Implement verification protocols, such as MFA, for high-value transactions, regardless of how authentic the request seems.

Numerous reputable vendors offer various encryption tools that meet Canadian privacy laws and industry standards, so select one that suits you or your business.

Instead of attaching sensitive documents via email, employ Advanced Encryption Standard (AES) with 256-bit keys for optimal security. This encryption standard offers robust protection for accounting databases and client files.

Whether you're sending documents or receiving e-mails with important information, using end-to-end encryption for all financial communications and transactions ensures data remains protected throughout its entire journey.

Backing up your data is essential since it ensures critical information (such as financial records, client details and operational files) can be quickly recovered in the event of accidental deletion, cyberattack or hardware failure.

As your data is crucial for your business, regular backups will safeguard against both human mistakes and system failures, which occur more often than you might expect. Typically, you should store copies of everything in several locations, such as in the cloud or on an external drive, in order to reduce the risk of losing everything.
