AI in cyber security – A small business guide Discover how AI is changing cyber security. Learn how smart technology and human awareness can work together to help detect, prevent and respond to modern cyber threats. 20 May 2026 · 6 minute read AI and cyber security - what it means for your business Artificial intelligence (AI) creates both new cyber security threats and risks, and new ways to stay secure online.  Cyber attacks are getting smarter, faster, and more frequent because hackers are increasingly using artificial intelligence (AI). But AI can also help support enhanced features in solutions businesses can use for cyber threat protection. Key insights Scammers and cyber criminals are using AI tools to threaten businesses of all kinds. AI can also help improve cyber security by helping to identify and stop cyber threats in real time. You don’t need to be an expert to use AI in cyber security as tools like Telstra’s Device Security for Business use AI to help protect your data and devices. Train your team with programs like Cyber Wardens that help teach small businesses how to stay alert to AI scams and online risks. In this guide we explore the role of AI in cyber security threats and opportunities. Learn how human input and the right solutions can together help boost business security. How cyber criminals use AI to target small businesses Scammers now use AI to create more targeted attacks that are harder to spot. These attacks can take the shape of everyday interactions. The Australian Cyber Security Centre (ACSC) reports that AI “creates an avenue for cyber criminals to streamline and scale their activities.” The technology can create realistic scams, reach more targets, and invade a network quickly. Here are some common examples. Hard to detect phishing emails AI can design and write emails that closely match a colleague or supplier’s usual style. You might receive a message with familiar branding or tone, asking you to click a link. Always confirm unusual requests with the sender before taking action. Learn more about phishing and how to help minimise risks to your business. Fake phone calls or deepfake messages Some scammers use AI to copy real voices. You could get a call that sounds like a manager or client, asking for sensitive details or a quick payment. If it doesn’t feel right, hang up. Then call them back on a known number. Login attempts using stolen passwords Some cyber criminals use AI and bots to test stolen login details across multiple websites. This is called credential stuffing. If you use the same passwords for different platforms, this can make it easier for hackers to break into your accounts. Develop good password management habits and turn on multi-factor authentication (MFA).   How AI helps defend your business AI isn’t just a tool for cyber criminals. It’s helping small businesses across Australia stay protected. Here’s how AI can help improve your cyber security. Detect threats in real time AI tools learn what normal activity looks like on your systems. When something unusual happens, they raise the alarm. This could be a login from an unknown location or a large, unexpected data transfer. This is called anomaly detection. Predict and prevent attacks AI can learn from previous cases of cyber attacks. By analysing those patterns, it can predict what is likely to happen next. This is known as predictive analytics. It helps identify and stop threats before they cause damage. Speed up response times When a threat is detected, AI can act quickly. It can block a suspicious login or shut down a risky connection. It can also isolate a device on your network to prevent an attack spreading. Protection without the complexity Many security features are now built into cloud services and cyber security platforms. This includes Telstra’s Device Security for Business which provides a layer of cyber threat protection against malware and phishing attacks.

It’s important to combine them with strong cyber security education for your employees. This human layer of protection helps your business stay ahead of modern cyber threats. Your staff are often the first and last line of defence. And their ability to pause, question, identify and report can make all the difference.
