Running a business today means dealing with endless cybersecurity risks. Many owners focus on growth but forget security. That mistake costs money, time, and reputation. One breach can put years of hard work at risk. Did you know that in Australia, 43% of cyberattacks target small businesses, and only 14% are prepared to defend them.
Business owners make multiple security mistakes that put them at risk. The 5 common mistakes that they make are:
- Using weak passwords and poor authentication
- Ignoring security awareness training
- Overlooking insider threats
- Weak network and cloud protection
- No security policies and compliance planning
We will go through the five biggest business security mistakes you must avoid. Each one comes with practical fixes that you can apply right now.
5 Business Security Mistakes You Must Avoid
Here, we have discussed the 5 common business security mistakes business owners make. We also discussed brief solutions to them so that you can avoid them and make your business secure.
1. Weak Passwords and Poor Authentication
One of the most common business security mistakes is that businesses use weak passwords. Business administrators or the owners are still widely using simple passwords like “123456” or “password.” Hackers love them because they take seconds to break.
According to the Verizon Security Report, 81% of breaches involve stolen or poorly managed passwords. That means your staff logins might already be a target.
Using strong passwords isn’t enough. You also need two-factor authentication (2FA). It adds a second layer, such as a text code or app approval. Even if hackers steal a password, they can’t log in without the second step.
Many businesses skip this because they think it slows down employees. In reality, it saves you from expensive data breaches. Because in Australia, a single data breach costs on average AUD $ 4.26 million.
Solution:
- Set your system’s passwords with at least 12 characters, numbers, and symbols.
- Enforce 2FA on all business accounts.
- Rotate passwords every 90 days.
- Use a password manager to simplify logins.
2. Ignoring Security Awareness Training
Phishing attacks are another big threat. Hackers send fake emails, texts, etc., that look like real ones. They trick employees into clicking links or sharing credentials because most employees are not trained about social engineering and lack security awareness.
In Australia, 5 in every 1,000 people click a phishing link, which is almost double the global average. Many companies still don’t train staff to spot them. That’s a huge cybersecurity risk. And phishing scams in Australia caused $13.7 million in financial losses in early 2025.
Phishing often leads to ransomware protection failures. Once hackers get in, they encrypt data and demand money.
Solution:
- Run regular security awareness training for staff.
- Teach employees to hover over links before clicking.
- Use email filters that block suspicious messages.
- Report phishing attempts immediately.
Training makes a difference. Businesses with trained staff can cut phishing success rates by up to 70%.
3. Overlooking Insider Threats
Not all risks come from outsiders. Sometimes employees, contractors, or partners cause damage—intentionally or by mistake. These are insider threats.
An employee might share files on personal devices, skip security policies and procedures, or fall for scams. In other cases, angry staff may steal or leak data.
According to Gurucul’s studies, 48% of organisations have experienced more frequent insider attacks, and 71% of organisations feel moderately vulnerable to insider threats in 2024. In Australia, insider-related cases are growing, especially in industries handling sensitive client information.
Solution:
- Limit access to data based on job roles.
- Monitor unusual logins or downloads using endpoint security tools.
- Review user permissions every quarter.
4. Weak Network and Cloud Protection
Businesses depend on networks and cloud services every day. But skipping firewalls and encryption is a dangerous business security mistake.
Unprotected Wi-Fi, open ports, and outdated software create network vulnerabilities. Hackers exploit these weaknesses to steal files or plant malware and spyware.
Cloud services add another challenge. Storing sensitive files without proper settings exposes you to cloud security risks. A misconfigured server can expose thousands of client records.
In 2022, 37% of Australian companies suffered cloud-related security incidents. That’s almost half of businesses relying on digital services.
Solution:
- Use strong firewalls and encryption.
- Update all devices and servers regularly.
- Audit your cloud security risks with IT experts.
- Segment networks so one breach doesn’t spread everywhere.
If you’re not sure how strong your systems are, you should consult with IT support services. They can run vulnerability scans and recommend fixes.
5. No Clear Security Policies, Poor Compliance, and Lacking Response Plans
The last big mistake is skipping formal security policies and procedures. Many businesses assume common sense is enough. It isn’t.
When an attack happens, confusion costs time and money. Without incident response planning, staff won’t know who to call or what to do.
Australian regulations like the Privacy Act 1988, with Other Legislation Amendments 2024, and international rules like GDPR, require strong data protection. Ignoring them risks you fines and lawsuits.
Solution:
- Write down your security response plan and share it with staff.
- Test your incident response planning with simulations.
- Stay updated on compliance and regulations for your industry.
- Review and update policies twice a year.
Having a plan turns chaos into quick action. With a strong incident response team and formal cyber response plan, organisations can reduce data breach costs on average to USD 473,706 per incident. Hackers expect confusion. Don’t give them the advantage.
