Cybersecurity is no longer just an IT concern - it’s a critical part of business strategy. For accounting firms and small businesses, protecting financial data is essential to maintaining trust and operational continuity.
Many organisations hold sensitive client information that, if exposed, could cause serious harm to both the business and its customers. With financial data being among the most targeted assets by cybercriminals, accounting and professional services remain high on the list for cyber attacks in Australia.
Outside of government departments, the financial services sector was the most targeted industry in FY 2024-25, with the cost of cyber incidents increasing by up to 55% for small and medium-sized businesses.
When it comes to cybersecurity, people are often the biggest vulnerability. Around 85% of cyber incidents are caused by human error - a careless click, a weak password, or a missed phishing warning.
Every business should build cyber awareness into its culture. Regular staff training helps employees recognise phishing attempts, understand the warning signs in suspicious emails, and maintain healthy password practices.
This simple but powerful step strengthens your risk management framework and reduces exposure to preventable threats. A well-trained team is just as important as the technology protecting your systems.
Legacy systems - from old computers to unsupported software - can quietly open security gaps in your business. Ignoring updates or delaying replacements can leave vulnerabilities unpatched, giving cybercriminals an easy entry point.
The Australian Signals Directorate’s Essential 8 Framework recommends applying critical vendor patches within 48 hours and non-critical updates within two weeks. This includes everything from your accounting software to your office operating systems.
For example, with Microsoft declaring Windows 10 as End of Life (EOL), devices still running on it no longer receive security updates, leaving them exposed.
Regular technology reviews should be integrated into your wider cash flow and business planning process to ensure your systems remain secure and efficient.
It’s impossible to defend what you can’t detect. Robust cybersecurity requires visibility - knowing what’s happening within your systems at all times. Setting up event logging, reporting, and alerting ensures that you can respond quickly to unusual activity.
In Australia, financial services businesses take an average of 288 days to identify a data breach. That’s nearly nine months of potential unauthorised access. Implementing alerts for irregular logins or unexpected data movement can reduce that detection time dramatically.
Maintaining good visibility also supports accurate record-keeping and bookkeeping and data accuracy, ensuring the integrity of financial information while reducing the risk of fraud or error.
Every organisation should have a Cyber Incident Response Plan (CIRP). It’s not just another policy document - it’s a roadmap for when incidents happen. A solid plan defines key roles, detection methods, evidence handling, and communication procedures.
Testing and refining the plan regularly ensures that your business can respond quickly, contain the damage, and recover effectively. For accounting and professional firms, a tested CIRP is vital to maintaining client trust and meeting compliance obligations.
Cybersecurity isn’t just about technology - it’s about business continuity. In today’s digital environment, your data, systems, and reputation are interconnected. Protecting one helps protect the others.
Embedding cybersecurity within your broader business strategy means integrating staff training, secure systems, data policies, and response plans into your everyday operations.
When cybersecurity becomes part of how you do business, not just something you react to, you safeguard your clients, your finances, and your future.
