10 cyber security threats putting your business at risk

Cybercriminals never take a day off, and your business is always in their crosshairs. But Cyber Security Awareness Month in October serves as a critical reminder—this is your chance to tighten your defences before it’s too late. Every second counts when protecting your organisation from attacks, and this month gives you the perfect opportunity to assess vulnerabilities and take proactive steps before a minor gap becomes a major disaster. 

Here are the 10 most critical cyber security threats your business should be aware of, and the actions you can take to defend your organisation. 

1. Phishing remains the top cyber 

security threat

Phishing attacks continue to be the most successful method cybercriminals use to breach systems.

Alarmingly, 74% of cyber breaches are caused by human factors – single employee clicking a fraudulent link can devastate your business. Employees are often the first line of defence, so regular training and simulated phishing exercises are essential to prepare them to identify suspicious emails. A single click on a fraudulent link can devastate your business. Creating a security-aware workforce is one of the most effective ways to guard against these threats. Explore how security awareness training can help build this resilience.  

2. Unverified USB devices introduce malware risks  

USB devices, though commonly used, can be a significant security risk. One infected device could be all it takes to compromise your network. Unverified or personal USB drives can introduce malware into your systems, causing disruption or data loss. To mitigate this risk, restrict USB access, use device control policies, and ensure your endpoints are secured. Regular network security measures can provide the necessary protection by scanning external devices before they connect to your systems. 

3. Remote work expands your attack

surface

With remote work now a standard for many businesses, every unprotected home network or personal device is an open door for attackers. Securing home networks and personal devices is no longer optional—it’s critical. Ensure that your remote workforce uses Virtual Private Networks (VPNs) and has endpoint protection in place. These measures secure connections and minimise the risk of a breach through home networks, preventing hackers from infiltrating your core systems. 

4. Unpatched software leaves you exposed 

Unpatched software and outdated systems are the easiest targets for attackers. Every delay in updating your software widens the window of opportunity for hackers to exploit known vulnerabilities. Don’t leave your business exposed—implement an automated patch management process to regularly update your systems and close vulnerabilities. Prioritise high-risk patches and use solutions like patch management as a service to stay ahead of potential attacks. 

5. Weak passwords make you vulnerable

A weak password is an open invitation to cybercriminals. Password-related breaches are among the simplest but most damaging. A strong password policy, combined with password managers and multi-factor authentication (MFA), can drastically reduce your risk. Encourage employees to create complex, unique passwords and update them regularly. A single compromised password can undo even the most sophisticated security measures. 

6. Insider threats are often overlooked

Not all threats come from outside your organisation. Disgruntled employees or those with poor security practices can cause significant harm. Ignoring insider threats can lead to breaches from within your own walls. Implementing strict access controls and monitoring user behaviour can help reduce this risk. Foster a strong security culture with regular education and awareness initiatives can minimise errors and increase vigilance across your organisation. Using Role-Based Access Control (RBAC) is another effective way to limit access to sensitive data based on job roles. 

7. Backups are your last line of 

defence against ransomware

Without tested backups, a ransomware attack could cripple your business for days or even weeks. Attackers are getting smarter, and if they take down your systems, backups may be your only path to recovery. Ensure that your backups are encrypted, stored offsite or in the cloud, and tested regularly. Test them frequently to ensure rapid recovery—because in the event of an attack, it’s not a matter of if you’ll need them, but when. 

8. Ransomware is becoming more sophisticated 

Ransomware continues to grow in complexity, targeting businesses of all sizes. Defend against this threat with strong endpoint security, regular employee training, and a solid backup strategy. Hackers often demand crippling payments in exchange for your data, and many businesses never fully recover. Having a comprehensive incident response plan in place can make the difference between recovery and long-term damage. Ensure your team knows exactly how to respond when ransomware strikes.  

9. Cloud security is essential as 

businesses scale

As more businesses move to the cloud, securing cloud infrastructure becomes increasingly important. Moving to the cloud may seem like a convenience, but without proper security, it can introduce risks that cripple your operations. Implement cloud security solutions, ensuring encryption, identity management, and regular monitoring to prevent unauthorised access and protect sensitive data.  

10. Incident response plans are a must-have

You can't always prevent a cyberattack but having a well-structured incident response plan ensures you can handle one efficiently. Every minute counts after a breach, and the first steps your team takes are critical. Regularly review and update your response plan to ensure swift, decisive action in an attack. Conduct regular security audits to identify gaps in your defences and improve your organisation’s ability to respond to incidents effectively. 

Strengthening your cyber defences: What’s next? 

Cyber security threats evolve constantly, and businesses that fail to adapt will be left vulnerable. While robust security measures are non-negotiable, continuous education, regular system updates, and a proactive security culture are your best defences. 

Don’t leave your organisation’s security to chance. Start with something as simple as enhancing employee awareness, or ensuring regular system updates. The time to act is now.
