Cyber Security Recommendations for Small Businesses

Cyber security is no longer something only large organisations need to worry about.

Small businesses are increasingly being targeted by cyber criminals because they often hold valuable data, rely heavily on email, and may not have the same level of protection as larger companies.

The good news is that improving cyber security does not always mean making things complicated. Many of the most effective steps are practical, affordable, and can make a significant difference to your business.

Here are some key cyber security recommendations every small business should consider.

1. Use Multi-Factor Authentication

Passwords alone are no longer enough.

Multi-factor authentication, often called MFA, adds an extra layer of protection to your accounts. This means that even if someone discovers a password, they still need a second form of verification to log in.

This could be an app notification, a code, or another approved sign-in method.

MFA should be enabled on important systems such as Microsoft 365, email accounts, banking platforms, remote access tools, admin accounts, and cloud services.

For most small businesses, enabling MFA is one of the quickest and most effective ways to reduce cyber risk.

2. Keep Devices Updated

Updates can be frustrating, but they are essential.

Cyber criminals often take advantage of known weaknesses in software, operating systems, browsers, and apps. Updates help fix these weaknesses before they can be exploited.

Your business should make sure that laptops, desktops, servers, phones, tablets, firewalls, routers, and business applications are kept up to date.

Where possible, updates should be automated and monitored so that devices do not fall behind.

3. Protect Email Properly

Email is one of the most common ways cyber attacks begin.

Small businesses should make sure their email platform is configured securely. This includes spam filtering, anti-phishing protection, safe link scanning, and protection against malicious attachments.

It is also important to configure email authentication records such as SPF, DKIM, and DMARC. These help protect your domain from being spoofed by attackers pretending to send emails from your business.

Staff should also be trained to look out for suspicious emails, especially messages involving payments, password resets, urgent requests, unexpected attachments, or changes to bank details.

4. Back Up Your Data

Backups are one of the most important parts of cyber security.

If your business is hit by ransomware, accidental deletion, hardware failure, or a compromised account, a reliable backup can be the difference between a quick recovery and a major incident.

Backups should be regular, secure, and tested.

It is not enough to assume your data is backed up. You need to know what is being backed up, how often it is backed up, where it is stored, and how quickly it can be restored.

This should include important business data, cloud files, emails, databases, and key systems.

5. Use Endpoint Protection

Traditional antivirus is no longer enough for many businesses.

Modern endpoint protection, such as Endpoint Detection and Response, helps detect and respond to suspicious activity on devices. This can include malware, ransomware, unusual behaviour, malicious scripts, and attempts to compromise systems.

Every business device should have suitable protection in place, especially laptops used outside the office.

Endpoint security is particularly important for businesses with remote workers, hybrid teams, or staff who regularly access company data from different locations.

6. Control User Access

Not every user needs access to everything.

One of the best ways to reduce risk is to make sure users only have access to the systems, files, and data they genuinely need.

This is known as the principle of least privilege.

Admin accounts should be limited, monitored, and only used when necessary. Staff who leave the business should have their access removed quickly. Shared accounts should be avoided wherever possible.

Good access control helps reduce the damage if an account is compromised.

7. Secure Remote Working

Remote and hybrid working are now normal for many businesses, but they need to be managed securely.

Staff working from home or on the move should use secure devices, protected connections, and approved business systems.

Remote access should be controlled using MFA, conditional access, VPNs where appropriate, and strong device security policies.

Businesses should also avoid allowing staff to store company data on unmanaged personal devices unless there are proper controls in place.

8. Train Your Staff

Technology is important, but your staff are also a key part of your cyber security.

Cyber criminals often rely on people making quick decisions under pressure. They may send emails pretending to be a supplier, a director, Microsoft, a bank, or a delivery company.

Cyber security awareness training helps staff recognise warning signs and know what to do if something looks suspicious.

Training should cover phishing, password security, safe internet use, payment fraud, data handling, and how to report concerns.

The goal is not to blame staff. The goal is to give them the confidence to stop, check, and report anything unusual.

9. Have a Cyber Incident Plan

Many small businesses do not have a plan for what to do if something goes wrong.

A cyber incident plan does not need to be complicated, but it should answer some important questions:

Who needs to be contacted?

How do you isolate affected devices?

How do you reset compromised accounts?

Where are backups stored?

Who deals with clients, suppliers, insurers, or regulators?

How do you continue operating if key systems are unavailable?

Having a plan before an incident happens can save time, reduce panic, and limit damage.

10. Work Towards Cyber Essentials

Cyber Essentials is a UK government-backed scheme designed to help businesses protect themselves against common cyber threats.

It focuses on important areas such as firewalls, secure configuration, user access control, malware protection, and security updates.

For small businesses, Cyber Essentials can be a useful way to check whether the right basic protections are in place.

It can also help demonstrate to clients, suppliers, insurers, and partners that your business takes cyber security seriously.

Cyber Security Does Not Have to Be Overwhelming

Many small businesses put off cyber security because they assume it will be expensive, complicated, or disruptive.

In reality, the best approach is to start with the basics and build from there.

The key is to understand your current risks, fix the obvious gaps, and make sure your systems are configured correctly.

Cyber security should protect your business without stopping your team from working.
