Why SMEs Struggle with Cybersecurity and How to Fix It

Why SMEs Struggle with Cybersecurity and How to Fix It

Cybersecurity can feel complicated for small and medium sized businesses.

Large organisations may have dedicated security teams, specialist tools and significant budgets. Most SMEs do not have that luxury.

Instead, responsibility for cybersecurity often sits with an IT provider, an internal IT person, a business owner, or sometimes a combination of all three.

At the same time, SMEs face many of the same cyber threats as much larger organisations.

The good news is that improving cybersecurity does not necessarily require a large security team or an expensive collection of tools. For most SMEs, the biggest improvements come from understanding the risks, getting the fundamentals right and improving security progressively.

Why Do SMEs Struggle with Cybersecurity?

1. Limited Time and Resources

For most SMEs, cybersecurity is competing with dozens of other business priorities.

Business owners need to focus on customers, employees, cash flow and growth. Internal IT teams may already be stretched supporting users and keeping systems operational.

Security improvements can therefore be postponed until there is an incident, a customer asks for evidence of security controls, or a certification becomes necessary.

The solution is not necessarily to spend more.

Start by identifying the systems and information that matter most to the business and concentrate security investment where it will reduce the greatest risk.

2. Nobody Clearly Owns Cybersecurity

One of the most common problems is unclear responsibility.

An organisation may assume its IT provider is responsible for security, while the IT provider believes its responsibility is limited to managing specific systems and services.

This creates gaps.

Every organisation should understand who is responsible for areas such as:

• Microsoft 365 security

• Endpoint protection

• Vulnerability management and patching

• Backups and recovery

• Identity and access management

• Security monitoring

• Incident response

• Staff awareness

• Supplier risk

You do not necessarily need a dedicated security manager, but someone needs to own the overall security risk.

3. Cybersecurity Has Become More Complex

Modern businesses rely on cloud services, laptops, mobile devices, SaaS applications, remote working and increasingly AI.

The traditional security perimeter has largely disappeared.

Attackers are also constantly changing their techniques. Phishing remains important, but businesses now need to consider attacks involving stolen credentials, MFA abuse, cloud services, collaboration platforms such as Microsoft Teams and legitimate administrative tools.

Trying to defend against every possible threat individually quickly becomes overwhelming.

A better approach is to establish strong security fundamentals that protect the organisation against multiple attack techniques.

4. Buying Security Products Is Easier Than Building Security

There is no shortage of cybersecurity products.

The problem is that buying another security tool does not automatically make an organisation secure.

A business may have antivirus, firewalls, Microsoft 365 security features, vulnerability scanners and backup systems while still having significant weaknesses because those technologies are not configured, monitored or managed effectively.

Before buying another product, ask:

What risk are we trying to reduce, and do we already have technology capable of addressing it?

Often, improving the configuration and management of existing systems delivers more value than adding another security product.

5. Businesses Don't Always Know Where Their Weaknesses Are

It is difficult to improve something you cannot see.

Common weaknesses such as excessive administrator privileges, unsupported software, missing security updates, weak Microsoft 365 configurations or unnecessary internet exposure can remain unnoticed for years.

This is why regular security assessments and vulnerability management are important.

The objective should not simply be to produce a long list of technical findings. It should be to understand which weaknesses create meaningful business risk and prioritise fixing them.

How Can SMEs Improve Their Cybersecurity?

The answer is usually not a huge transformation programme.

Start with the fundamentals.

Establish a Security Baseline

Frameworks and standards such as Cyber Essentials provide SMEs with a practical starting point for protecting against common cyber attacks.

They can also help organisations establish consistent security controls rather than making individual security decisions in isolation.

Protect Identities

User accounts are increasingly a primary target for attackers.

Multi factor authentication, sensible access controls, separate administrative accounts and removing unnecessary privileges can significantly reduce risk.

Keep Systems Secure and Updated

Security vulnerabilities are continually discovered.

Organisations need a reliable process for identifying vulnerabilities, applying security updates and addressing serious weaknesses quickly.

This should include operating systems, applications, cloud services and internet facing infrastructure.

Secure Cloud Environments

Microsoft 365 and other cloud platforms provide extensive security capabilities, but they still need to be configured appropriately.

Default configuration should not automatically be assumed to represent the right security posture for every organisation.

Regular security reviews can identify unnecessary exposure and opportunities to strengthen the environment.

Prepare for an Incident

No organisation can eliminate cyber risk completely.

Businesses should therefore know what they would do if an important account was compromised, ransomware affected their systems or critical information became unavailable.

That includes understanding who to contact, how systems would be recovered and whether backups actually work.

Make Security Continuous

Perhaps the biggest change SMEs can make is to stop treating cybersecurity as an annual exercise.

Passing a certification or completing a penetration test provides useful assurance at a point in time, but businesses and technology continually change.

New employees join. Systems are introduced. Permissions change. New vulnerabilities appear.

Cybersecurity therefore needs to become a continuous process of reviewing, improving and validating security controls.

Cybersecurity Doesn't Need to Be Complicated

SMEs do not need the cybersecurity programme of a multinational organisation.

They need security that is proportionate to their risks, understandable to the people running the business and sustainable with the resources available.

Start with the fundamentals.

Understand what matters most.

Identify the biggest risks.

Fix the important weaknesses first.

Then keep improving.
