Professional practices hold some of the most sensitive data in Australia. Client financial records. Medical histories. Legal case files. Engineering project documents. If a cyber attack hits your practice, it is not just an IT problem. It is a client trust problem, a regulatory problem, and potentially a business survival problem.
The good news is that most attacks on small practices are preventable. They rely on human error, not sophisticated hacking. Here are the practical steps every practice should take.
Why professional practices are targeted
Cyber criminals target professional practices because the data is valuable and the defences are often weak. A solo accountant with access to hundreds of clients’ tax file numbers is a more attractive target than a large corporation with a dedicated security team.
In our experience working with practices across Australia, the most common attacks are not dramatic. They are quiet. An invoice with changed bank details. A phishing email that looks like it came from the ATO. A compromised email account used to redirect client payments.
The eight steps every practice needs
1. Turn on multi-factor authentication everywhere
This is the single most effective thing you can do. Multi-factor authentication (MFA) means that even if someone steals your password, they cannot log in without a second verification step. Turn it on for email, practice management software, cloud storage, and banking. No exceptions.
2. Use a password manager
If anyone in your practice reuses passwords or keeps them in a spreadsheet, you have a problem. A password manager like 1Password or Bitwarden generates and stores unique passwords for every account. The whole team should use one.
3. Keep software updated
Software updates often contain security patches for known vulnerabilities. When you delay updates, you leave the door open. Set automatic updates on all devices. This applies to your operating system, browser, practice management software, and any plugins on your website.
4. Train your team to spot phishing
Most successful attacks start with a phishing email. Someone clicks a link they should not have clicked. Train your team to check sender addresses carefully, hover over links before clicking, and verify any unexpected requests for payment or credentials by phone.
Run this training at least twice a year. New phishing tactics emerge constantly.
5. Back up your data with the 3-2-1 rule
Keep three copies of your data, on two different types of storage, with one copy stored offsite or in the cloud. If ransomware encrypts your files, a clean backup means you can recover without paying.
Test your backups regularly. A backup you have never tested is a backup you cannot trust.
6. Secure your email domain
Set up SPF, DKIM, and DMARC records on your email domain. These protocols stop attackers from sending emails that appear to come from your practice. Your IT provider or web host can set this up in under an hour.
7. Review who has access to what
Does every team member need access to every system? Probably not. Limit access based on what each person actually needs for their role. When someone leaves the practice, remove their access immediately. Not next week. That day.
8. Have an incident response plan
If something goes wrong, you need to know who does what. Who contacts clients? Who calls the IT provider? Who notifies the Australian Cyber Security Centre? Write it down. Keep it accessible. Review it annually.
AI can help with cybersecurity too
AI-powered security tools can now monitor your email for phishing attempts, flag unusual login patterns, and detect suspicious activity across your systems in real time. These tools are becoming affordable for small practices and are worth investigating.
At Navii, we help practices assess their security posture as part of our AI systems work. There is no point connecting your tools with AI if the foundation is not secure.
Take action today
You do not need to do everything at once. Start with multi-factor authentication and a password manager. Those two steps alone will block the majority of common attacks.
