10 Cybersecurity Best Practices for your small businesses

We know that as a small business owner, you have a lot on your plate. Between looking after customers, managing your team, and keeping things running smoothly, cybersecurity might not always be top of your list.

But here is the good news: you do not need to be an IT expert to make your business more secure.

By putting a few simple habits in place, you can reduce the risk of cyberattacks and keep your people and data safe. Here are ten practical tips you can start using today to improve your cybersecurity.

1. Use Strong, Unique Passwords

Let us start with a classic. Weak or reused passwords are still one of the main causes of business data breaches.

Every account should have its own strong, unique password. Avoid using the same password across multiple platforms. A good password manager can help you generate and store them safely. It is also a good idea to update passwords regularly, especially for sensitive accounts.

2. Enable Multi-Factor Authentication

Multi-factor authentication (MFA) adds an extra layer of protection. It requires a second form of identification, such as a code sent to your phone, along with your password.

If a hacker gets hold of your password, MFA can still stop them from accessing your account. Use it wherever it is available, particularly for email, banking, and cloud services.

3. Recognise and Report Phishing Emails

Phishing emails are designed to trick you into clicking a dodgy link or handing over sensitive information.

Look out for urgent or unexpected requests, spelling mistakes, unfamiliar email addresses, and suspicious attachments. If anything feels off, do not click on anything. Instead, report it to your IT support or the person responsible for cybersecurity in your business.

4. Be Wary of Unsolicited Phone Calls

Cybercriminals do not just use email. Sometimes they will call, pretending to be from your bank, IT provider, or another trusted organisation.

Never share personal or business information over the phone unless you are certain who you are speaking to. If in doubt, hang up and contact the company directly using a number you know is genuine.

5. Use Secure Wi-Fi Networks

Avoid using public Wi-Fi for work-related activities. Networks in cafes, hotels, or airports are often unsecured and could allow attackers to intercept your data.

If you need to work while on the move, use your mobile data or connect through a reputable Virtual Private Network (VPN) to keep your connection safe.

6. Do Not Plug In Unknown USB Devices

It might sound harmless, but plugging in an unlabelled USB drive could infect your computer with malware.

If you find a USB stick lying around, resist the urge to plug it in. Only use company-approved storage devices or secure cloud services to transfer files.

7. Secure Your Workstation

It only takes a few seconds for someone to access your information if you leave your screen unlocked.

Make it a habit to lock your computer whenever you step away, even if it is just to make a cup of tea. It is a small step that helps prevent unauthorised access in the office or while working remotely.

8. Be Careful What You Share on Social Media

Think before you post. Information you share publicly, such as your job role, company structure, or upcoming travel, can be useful to cybercriminals.

Avoid posting anything that could give away sensitive business information or help someone guess your passwords or security questions.

9. Avoid Suspicious Downloads

Only download software, apps, and files from trusted sources. If you are unsure about the legitimacy of a website or link, it is best to leave it alone.

Stick to official app stores or verified vendors, and always double-check before installing anything on a company device.

10. Follow Company Policies

If your business has IT and data protection policies in place, make sure you know what they are and follow them. They exist for a reason and help keep everyone on the same page when it comes to staying safe online.

If policies are unclear or out of date, it might be time for a refresh. A quick team meeting or training session could make a big difference.

Keeping It Simple, Staying Secure

Cybersecurity does not need to be complex. A few small changes in your daily habits can make a real difference to how well your business is protected.

Whether it is using stronger passwords, being more cautious with emails, or locking your screen when you step away, every action helps.
