Introduction
Artificial intelligence is changing cybersecurity, and not only by creating new threats. For Australian small businesses, it is also creating opportunities to access increasingly capable security tools, improve cyber awareness, and strengthen protection without necessarily needing a dedicated IT department.
The Australian Signals Directorate (ASD) has highlighted both sides of this development in its newly released Annual Cyber Threat Report 2025–26. During the reporting year, the Australian Cyber Security Centre (ACSC) received more than 82,000 cybercrime reports, approximately one every six minutes.
AI is helping malicious actors produce more convincing scams, identify vulnerabilities, and conduct attacks with greater speed and scale. But AI can also help defenders detect suspicious activity earlier, investigate threats, and respond more efficiently. For a small business, this means learning to protect the business from AI-enabled threats while making practical use of AI for better security.
Advanced cybersecurity is becoming more accessible
Not long ago, sophisticated threat detection and response were largely associated with larger organisations and specialist security teams. Today, smaller businesses can access many of these capabilities through subscription software designed for modest budgets and limited technical resources.
Modern security products can use machine learning, behavioural analysis, and automated response capabilities to identify suspicious activity that conventional signature-based antivirus protection might miss. For example, rather than simply recognising a known malicious file, some products can identify unusual behaviour associated with ransomware or other attacks and take protective action.
Five options worth investigating are:
Microsoft Defender for Business
Microsoft offers AI-powered endpoint protection designed for businesses with up to 300 users.
Capabilities include:
Next-generation antivirus protection.
AI-powered endpoint detection and response.
Vulnerability management.
Automated threat investigation and remediation.
Protection across supported Windows, macOS, Android and iOS devices.
As at 27 October 2026, Microsoft's Australian advertised price starts at A$4.50 per user per month, paid annually, excluding GST. Defender for Business is also included in Microsoft 365 Business Premium, so businesses already using that subscription may have access without purchasing another product.

These are examples, not universal recommendations. The best choice depends on the business's existing devices, subscriptions, risks, and ability to manage alerts. Before purchasing anything, check which security features are already available through your operating systems and software subscriptions.
AI-powered security software is not the same as a general-purpose AI assistant. Detection systems operate through specialist security technologies, while assistants such as ChatGPT, Claude, or Copilot can help people understand risks and prepare security activities. Each has a different role.
Five practical ways to use a generative AI assistant for cybersecurity
Even without purchasing specialist security software, small businesses can use a general-purpose AI assistant to improve security awareness, documentation, and planning. The safest starting point is to use AI as an adviser, with no direct access to business accounts, devices or sensitive information.
Here are five useful examples.
1. Identify gaps in your existing security arrangements
An AI assistant can help create a structured security checklist suited to a small business. For example, describe a hypothetical four-person landscaping business using laptops, mobile phones, cloud storage, accounting software, and a home office.
Ask: "Create a prioritised cybersecurity checklist for this type of Australian small business, covering accounts, devices, customer information, backups, Wi-Fi, and remote working. Base the recommendations on current ACSC guidance."
The resulting checklist provides a starting point for reviewing what is already in place, what needs improvement, and which matters deserve professional attention. Use generalised descriptions rather than uploading actual network configurations, account inventories, or confidential records.
2. Understand and configure existing security features
Many businesses already pay for software with security features they have never explored. An AI assistant can explain unfamiliar settings, identify relevant vendor guidance, and help organise implementation steps.
For example: "Explain the main security features available in Microsoft 365 Business Standard and Business Premium. Which require configuration, and what should a five-person Australian business prioritise?"
The assistant can help clarify the choices and locate official instructions. However, feature availability, licensing and configuration steps must be verified against current vendor documentation before making changes.
3. Create realistic cybersecurity training
Small businesses rarely need elaborate training programs, but staff should understand common risks. An AI assistant can create short, relevant learning exercises using fictional scenarios.
For example: "Create five realistic phishing and invoice-fraud scenarios for a small Australian construction business. Explain the warning signs and the safest way to verify each request."
This can help employees practise recognising suspicious messages, unexpected payment changes, impersonation, and potentially AI-generated communications. Training is especially useful when paired with one clear business rule: verify unexpected financial or sensitive requests through a trusted, independent communication channel.
4. Prepare for a cybersecurity incident
A business can have good security and still experience an incident. An AI assistant can help draft a simple response plan covering who to contact, what information to preserve, how to report an incident, and how essential work might continue.
For example: "Develop a one-page cybersecurity incident response checklist for a three-person professional services business. Include suspected email compromise, ransomware, lost mobile devices, and recovery from backups. Use Australian government guidance."
The draft can then be reviewed, corrected and tested through a short hypothetical exercise. An AI-generated plan is not a substitute for specialist incident response. During a real incident, avoid entering sensitive evidence into an unapproved AI service or allowing it to make changes to affected systems.
5. Review the security implications of new technology
Before introducing a new application, automation, or AI tool, a business can use an assistant to develop questions for evaluating it.
For example: "Create a vendor security assessment checklist for a small business considering a new AI-powered customer management application. Cover data handling, access permissions, integration, backups, incident response, and the provider's use of customer information."
This helps make cybersecurity part of the technology decision rather than an issue discovered after implementation. The assistant should help organise the evaluation, not independently declare a product secure.
Don't forget the office, home office and mobile devices
Small businesses increasingly operate across several environments. A business owner might work from a home office, manage customer enquiries on a mobile phone, access documents at a client's premises, and use cloud applications from multiple devices. Cybersecurity needs to account for the entire working environment.
For mobile phones and tablets, practical safeguards include:
Enable automatic operating-system and application updates
Use strong device locking and supported biometric authentication
Enable MFA or passkeys for business accounts
Review application permissions and remove unnecessary access
Enable device-location and remote-lock or erase capabilities where supported
Separate business information from personal applications where practical
For home offices and small workplaces, focus on:
Changing default router administration credentials
Keeping router firmware current
Using strong Wi-Fi encryption and credentials
Disabling unnecessary remote administration and Universal Plug and Play
Separating guest or smart-home devices from business devices where practical
Maintaining secure backups and testing recovery
The ACSC's Small Business Cyber Security Handbook and remote working guidance provide practical instructions. An AI assistant can help convert this guidance into a manageable checklist, but should not be given unrestricted access to routers, devices, or administration consoles.
When AI joins the team, cybersecurity needs to evolve too.
There is another important dimension to this discussion. Businesses are increasingly using AI not only to provide information but to carry out work. An AI assistant connected to email, business documents, customer databases, or other applications can introduce new information-security risks.
This connects to an important question explored in our earlier article, Who is in control when AI acts for your business? The more an AI system can access and do, the more carefully its authority must be managed. Three considerations are particularly important.
First, protect the information AI can access.
Establish what business information may be shared with an AI provider. Check its privacy practices, retention terms, processing locations, and whether submitted data may be used for model training. Avoid submitting passwords, recovery codes, personal customer information, confidential records, or raw security logs to an unapproved AI service. Removing names alone may not sufficiently anonymise information.
Second, limit what AI can do.
An AI system helping draft emails does not automatically need permission to send them. One reviewing documents does not necessarily need permission to modify or delete them. An assistant researching cybersecurity should not be authorised to change security settings simply because it recommends doing so. Apply the principle of least privilege, grant only the necessary access and require human approval for sensitive or consequential actions.
Third, recognise that AI introduces some distinctive threats.
One example is prompt injection, where malicious instructions embedded in an email, document or website attempt to influence an AI system's behaviour. A business using AI agents with connected tools needs controls beyond simply telling the assistant to behave securely. Permissions, approval requirements, monitoring, audit records, and the ability to disable access remain essential.
ASD's Agentic AI Harnesses guidance discusses these risks and the importance of security controls surrounding the AI model.
Where should a small business begin?
The opportunity is significant, but cybersecurity improvement does not need to begin with an expensive product or a complicated implementation.
A practical starting sequence is:
Protect the essentials. Enable MFA, install updates, maintain backups, and review account and device security.
Understand what you already have. Check the protections included in your devices and existing subscriptions.
Identify meaningful gaps. Consider your business information, working arrangements, risks, and available resources.
Explore AI where it adds value. Use suitable tools to improve detection, security awareness, planning, and response.
Keep reviewing. As your business, technology, and threats change, revisit the controls that protect your operations.
For businesses that need support, the ACSC provides free cybersecurity guidance and a 24-hour hotline on 1300 CYBER1 (1300 292 371). Suspected incidents can also be reported through cyber.gov.au/report.
Better cybersecurity is part of building a better business system
Cybersecurity needs to be treated as an integral part of routine everyday operations, as much of a habit as opening and closing the office each day, and it is intertwined in how the business's information, applications, processes, people, and working practices fit together. At Scaling It, this is central to Resilience: developing a business system that can withstand disruption, adapt to challenges, and continue supporting business objectives.
The growing capabilities of AI create valuable opportunities to strengthen that resilience, but the greatest benefit comes from choosing technology that fits the business, using it appropriately, and maintaining control over how it operates.
The goal is more than just achieving advanced cybersecurity. It's to build a business that can work confidently with today's technology and adapt safely to tomorrow's.
Scaling It. Better systems. Stronger businesses.
