In 2024 alone, the cost of data breaches skyrocketed to nearly $5 billion. That’s a lot of zeros, but not an entirely surprising number considering how much technology we rely on today. And, with smart technology becoming smarter by the day, our lives are more connected than ever. From phones and laptops to fridges, baby monitors, and even our cars, almost everything we use holds or transmits some form of data.
And where there’s data, there’s risk.
No one’s immune. Individuals, small businesses, large corporations, and government agencies. Everyone is a potential target. And let’s be honest: data is gold. From email logins and banking details to customer records and sensitive internal documents, your business holds a treasure trove of information that cybercriminals would love to get their hands on.
That’s why protecting your digital assets is essential. So, the big question is: Are you doing enough to keep your business data safe?
In this guide, we’ll walk you through what data theft really is, why it’s such a big threat, and, most importantly, what you can do to prevent it. We’ll cover practical strategies, smart tools, and best practices to help secure your business from increasingly clever (and relentless) cyber threats.
Let’s start with the basics. What exactly is data theft?
In simple terms, data theft is the unauthorised access, copying, or transfer of sensitive information without permission. But unlike physical theft, where something tangible is taken, data theft is much sneakier. The original information often remains untouched, making it incredibly hard to detect right away.
But what kind of data are we talking about? Here’s what cybercriminals are typically after:
What makes data theft particularly harmful is how silently it happens. There’s no broken window or missing computer to alert you. The attacker just copies what they need and slips away, often leaving no obvious trace. This means that your systems might look fine on the surface, and you don’t even know you’ve been targeted until the damage has already been done.
And the longer the breach goes unnoticed, the more time an attacker has to exploit your data, potentially causing far-reaching damage to your operations, finances, and reputation.
Chances are, your business stores some variation of sensitive information. This can be customer credit card details, employee records, internal reports, proprietary tools or formulas – the list goes on. This information is essential to your day-to-day operations, but it also makes your business a prime target for cybercriminals.
If you think data theft is something that only happens to big corporations, think again. Between January and June 2024, the Office of the Australian Information Commissioner (OAIC) received a record 527 data breach notifications, a 9% jump in just six months. In fact, one breach alone affected more than 10 million Australians!
Here are a few more eye-opening stats:
The takeaway is: Data theft isn’t just a tech issue; it’s a serious business risk. And, with threats growing in scale and complexity, staying protected means being proactive.
When we think of data theft, it’s easy to imagine the immediate fallout—panic, disruption, and damage control. However, a single breach can send shockwaves through every part of your business, affecting everything from finances and customer trust to legal standing and market competitiveness.
The financial toll of data theft has never been higher. In 2024, the global average cost of a data breach climbed to AUD 7.46 million, a record high that’s only expected to get higher. And if you’re in the financial industry,y the average costs around AUD 6.08 million.
These numbers factor in everything from data recovery and fixes to disruption in operations, loss of customers and stakeholders and more. Around 75% of breach-related costs come from lost business, higher insurance premiums, and post-incident responses like:
Large-scale breaches (think 50 million records or more) can skyrocket to costs of around AUD$ 375 million. Fortunately, businesses using proactive strategies, AI and automation in their security strategies save nearly AUD$ 1.9 million compared to those without them.
For many businesses, the biggest blow isn’t financial, it’s the loss of customer trust. Retaining customers is far easier (and cheaper) than finding new ones. So, Trust, once broken, can be one of the most expensive things to repair.
66% of consumers say they wouldn’t trust a company again after a data breach, and even if they haven’t been affected, a majority are ready to switch brands entirely if there’s any cybersecurity issue or won’t do business with them in the first place.
In an effort to protect its individuals, Australia’s privacy laws are becoming stricter, and the penalties steeper. If your business experiences a serious or repeated breach, you could face a range of fines and consequences. Class actions, legal fees, long-term monitoring obligations, and mandatory upgrades to your security systems can all follow as well.
While you’re scrambling to respond to a data breach, competitors are still moving forward. A serious incident can derail your product development, delay launches, and push customers toward businesses with more robust security.
Worse still, if intellectual property is stolen, like trade secrets, proprietary systems, or research, you’re not just losing data; you’re losing your competitive edge. That’s hard to recover, especially for smaller businesses with fewer resources and less room for error.
Data theft comes in many sizes, shapes and forms. And as cybercriminals get smarter, it’s more important than ever to understand how these threats show up. Knowing what you’re up against is the first step to protecting your business and staying one step ahead.
Outside threats are the most common types of data theft. These attacks come from cybercriminals who target your business from the outside, often using tactics like hacking and phishing.
Phishing is especially common, where attackers pretend to be someone you trust (maybe a bank, a supplier, or even your own company) via emails, texts, or messages. These fake communications often include:
We have seen the rise of spear phishing – a more targeted version that uses specific information about your business to trick employees and vishing – using voice calls or voicemails to impersonate trusted figures. These can be surprisingly convincing and are designed to steal customer data, financial info, or even your internal systems access.
While we tend to focus on external hackers, sometimes the bigger threat is closer to home. Internal threats, accidental or intentional, can cause just as much damage.
In fact, employee negligence is responsible for a majority of internal breaches and 1 in 4 data breach incidents come from internal leaks. That could be anything from sending the wrong file to the wrong person to forgetting to secure a company laptop.
And then there are malicious insiders, employees who misuse their access for personal gain, revenge, or other reasons. This might look like sharing or selling confidential data, tampering with access credentials or changing IT systems to create backdoors for attackers.
Even in a digital-first world, physical data theft is still a problem. Unsecured laptops, mobile phones, and even paper files can be prime targets for theft.
This risk grew even more with the rise of remote work. Devices taken offsite, and often away from secure networks, became easier targets. A lost or stolen device can expose everything from passwords and emails to financial details and personal customer information.
So, don’t forget about physical security. Lock devices, store sensitive documents safely, and have clear policies in place for handling confidential information outside the office.
Some attacks go beyond stealing data, they take it hostage. Ransomware is a type of malware that encrypts your files, locking you out of your own systems. The catch? Payment is demanded (usually in cryptocurrency) to get access back. Worse still, attackers have started to exfiltrate (aka steal) the data first, then threaten to publish it if their demands aren’t met.
These advanced threats require smart, proactive protection measures to keep these sophisticated attackers at bay.
No business is immune to security risks, but understanding where your weak spots are is the first step toward protecting your valuable data.
If your team is still using passwords like “123456,” it’s time for a serious upgrade. Weak credentials are like leaving the front door wide open for cybercriminals, and in 2024, compromised passwords were one of the leading causes of cyberattacks.
One of the simplest and most effective fixes is multi-factor authentication (MFA). It adds an extra layer of security by requiring a password and an authentication token (typically a code or biometrics). With MFA in place, your risk of being hacked drops by up to 99%.
Working from airports, cafes, or hotels might be convenient, but public Wi-Fi networks are not secure. Without proper encryption, attackers can easily intercept your online activities, including banking information and login credentials. A Virtual Private Network (VPN) encrypts your internet connection, making your data unreadable to prying eyes.
Regular, plain-language cybersecurity training is so important. Educating your team on how to spot phishing emails and practice safe digital habits turns your people into a powerful first line of defence.
Putting off software updates might seem harmless, but these updates often include patches for known vulnerabilities. Businesses that don’t keep their systems current are more likely to fall victim to ransomware. Setting up automated patching systems ensures your software stays up to date and your business is protected.
Not everyone needs access to everything. Giving employees more access than they need can open up various security gaps. Implementing role-based access control (RBAC) means staff only see what’s relevant to their job. It’s cleaner, safer, and makes managing permissions easier, too.
Security audits provide clear visibility into your organisation’s cybersecurity environment and preparation level for various threats. These assessments typically evaluate whether your system adheres to established security criteria while identifying potential breach points.
Cyber threats are evolving fast. One of the biggest game-changers in data theft protection today is the rise of artificial intelligence (AI) and other emerging technologies. They bring a whole new level of speed, accuracy, and efficiency to the table. From advanced threat detection to automated incident response, these technologies help identify suspicious behaviour in real time and take immediate action – even before anyone notices a problem!
Predictive analytics also allows businesses to anticipate potential threats based on patterns and behaviours, enabling you to implement preventative measures before incidents ever occur. It learns and adapts over time, and as new threats emerge, the technology evolves, constantly refining its ability to spot and neutralise risk.

When it comes to protecting your business from cyber threats, your employees are either your strongest shield or your weakest link. With the right training and support, they can become a powerful line of defence.
Most cyberattacks don’t need fancy tech. Despite our technology driven society, not everyone is fully educated or aware of the risks. A click on a phishing email, a misplaced USB drive, or a weak password are often the first breaches.
Creating a culture of security awareness means building the beliefs, values and awareness that shape how employees act when it comes to protecting their organisations from cyberattacks.
So, how do you build that kind of culture?
Confusion is the enemy of security. That’s why it’s so important to have straightforward, easy-to-follow policies for handling data. Start by classifying your data based on sensitivity (e.g., public, internal, confidential), and then define how each type should be accessed, stored, and shared.
Key things to include:
It’s one thing to learn about security threats in a presentation. It’s another to practice dealing with them in real time.
Phishing simulations, for example, are a great way to test your team’s readiness and teach them what suspicious emails really look like. Just like fire drills, these exercises prepare people to respond calmly and effectively when the real thing happens.
Most importantly: keep the focus on learning, not blaming. These exercises are about building skills and boosting confidence, not pointing fingers.
The right mix of security tools provides thorough protection against the various threats targeting your business data. Let’s take a closer look:
Let’s start with the essentials. Beyond you employees, firewalls is the first line of defence when it comes to data protection. They monitor what’s coming and what’s going out, blocking anything potentially dangerous and suspicious. Firewalls are robust and are able to recognise users no matter where they’re logging in from or what device they’re using.
Pair that with antivirus and anti-malware software, and you’ve got a strong first line of defence. These programs protect against everything from old-school viruses to more modern threats like:
While most systems come with basic protection these days, investing in a third-party security software often provides more advanced features, like dedicated ransomware protection and smarter, faster scanning.
DLP solutions monitor how data moves within your network—across cloud platforms, local devices, and everything in between. They are a set of tools and processes that help automatically classify sensitive information, detect unusual or risky activity and enforce policies to keep your business compliant.
With so much collaboration happening online, secure cloud storage is a must. Fortunately, many enterprise-grade cloud platforms offer features designed specifically to protect your data, including End-to-end encryption (so not even the provider can access your files), secure sharing permissions and detailed activity logs.
Data theft can happen at any time. So your systems need to be constantly on alert. While it doesn’t automatically block threats it plays a crucial early-warning role in your cybersecurity strategy.
Intrusion Detection Systems (IDS) monitor your network for signs of unusual or malicious activity using two key methods:
No single tool can protect your business on its own. But together, these technologies create multiple layers of defence. The goal of layered protection is to make life harder for attackers at every turn. If a cybercriminal manages to bypass one defence, another is waiting to stop them—or at least slow them down long enough for you to detect and respond.
By combining them with strong internal policies and well-trained staff, you dramatically reduce your risk of data theft and give your business the digital security it needs to thrive.
The Privacy Act 1988 is the cornerstone of Australia’s data protection framework. It applies to most government agencies and businesses with an annual turnover of more than AUD 3 million (or AUD 4.59 million in some contexts), as well as smaller organisations handling sensitive information.
At its core are 13 Australian Privacy Principles (APPs), which set out how you must collect, store, use, and disclose personal information. Additionally recent changes to the law have significantly increased the penalties for serious or repeated privacy breaches.
Mistakes happen. But when a data breach occurs, transparency is key. Under Australia’s Notifiable Data Breaches (NDB) scheme, you’re legally required to notify both The Office of the Australian Information Commissioner (OAIC), and anyone whose personal information is likely to result in serious harm.
This applies when there’s an eligible data breach, which generally means personal information has been accessed or disclosed without authorisation (or lost in a way that’s likely to result in unauthorised access), and it’s likely to cause serious harm (such as identity theft, financial fraud, or reputational damage)
You have up to 30 days to assess whether a breach is eligible, and if it is, notification must happen as soon as practical. There are a few limited exemptions, such as when another agency is already handling the notifications, or if you’ve taken prompt action that completely neutralises the risk before any harm occurs.
Data breaches can feel overwhelming, but how you respond can make all the difference and why having a clear plan of action matters.
The moment you suspect a data theft incident, time is of the essence. Quick containment can help prevent further loss and keep damage to a minimum.
Once you’ve contained the breach, it’s time to notify the people who need to know, starting with an assessment under the Notifiable Data Breaches (NDB) scheme. You have 30 days to determine whether the breach meets the criteria of an “eligible data breach”, meaning it’s likely to result in serious harm to affected individuals.
If it does:
Open, transparent communication goes a long way in maintaining trust, even in difficult situations like data theft.
Even if you have strong in-house IT support, you don’t have to do it alone. A data breach is complex, and having the right specialists can ensure the best outcome.
Bringing in expert support gives you peace of mind and helps you respond thoughtfully, thoroughly, and lawfully.
Once the dust settles, it’s time to look back, and move forward with stronger protection in place.
Your post-incident plan should include:
Data theft is a significant business threat with real-world consequences. From financial loss to reputational damage, the fallout from a breach can be severe. By combining smart tools, strong internal processes, legal compliance, and a culture of cybersecurity awareness, you can ensure your data is protected by the best.
