Why the importance of cyber security is rising for everyone

(originally published September 2021, updated July 2025)

Understanding the importance of cyber security

Every click, message, and online transaction carries a risk, as digital technology becomes more central to daily life. The importance of cyber security is increasing for individuals, families, and businesses alike, with cyber-attacks no longer rare events, but a persistent reality that can affect anyone, regardless of age, industry, or experience.

The evolving threat landscape

Cyber threats have grown more sophisticated and targeted, with today’s attackers use tactics like - 
•    Social engineering and phishing to steal credentials
•    Ransomware to lock valuable files or systems
•    Malware that spreads through downloads or email attachments
•    Data breaches exposing sensitive customer or financial information

Small businesses are particularly vulnerable, as attackers often see them as easier targets due to limited resources or outdated defences. Individuals, too, can be affected by identity theft, scams, or loss of personal data.

The real-world impact of poor cyber security

The consequences of a cyber-attack can be far-reaching, like -
•    Loss of revenue and productivity for businesses
•    Permanent loss of important data or intellectual property
•    Erosion of customer trust and damage to reputation
•    Emotional distress and financial hardship for individuals

For small businesses, even a minor incident can disrupt operations and lead to costly recovery efforts.

Building resilience with practical cyber security habits

1. Prioritise regular backups
Keep up-to-date copies of your important files stored securely, preferably offline or in the cloud, which will allow recovery quickly if data is lost or held for ransom.

2. Strengthen your defences
Use firewalls, antivirus software, and network monitoring tools to block threats before they cause harm.

3. Stay informed and alert
Educate yourself and your team about common scams, phishing techniques, and safe online behaviours. 

4. Control access to sensitive information
Limit who can view or edit critical data, use strong passwords, multi-factor authentication, and review permissions regularly.

5. Update everything
Apply security updates and patches for all devices, apps, and systems as soon as they become available.

Creating a culture of cyber security

Good cyber security is not just about implementing technology solutions, but also people’s behaviour and encouraging good habits. Open conversations about risks make it easy for staff or family members to report suspicious activity, and then push to review your security practices regularly, with a goal to make security second nature, not an afterthought.

Looking forward

The importance of cyber security will only continue to grow as our lives become more digital, and by taking proactive steps now, you can reduce risk, protect what matters most, and build confidence in the digital world, whether you are running a business or looking after your family.
