Cyber Security for Small Businesses in the UK: What You Actually Need

Cyber security for small businesses in the UK: what you actually need

The cyber security industry has a problem. Most of its advice, tools, and frameworks are designed for organisations with dedicated IT teams, six-figure security budgets, and compliance departments. The result is that small business owners — who face many of the same threats — are either overwhelmed by complexity or lulled into thinking security is someone else's problem.

It is not. And the consequences of getting it wrong are increasingly severe.

The threat landscape for UK small businesses

The UK government's 2024 Cyber Security Breaches Survey found that 50% of UK businesses experienced a cyber attack or breach in the previous 12 months. Small businesses are far less equipped to recover when something goes wrong.

The most common attacks against small businesses are not sophisticated. They are opportunistic. Automated tools scan the internet continuously for websites running outdated software, weak passwords, and unpatched vulnerabilities.

What you actually need

Strong passwords and a password manager. The single most common entry point for attackers is weak or reused credentials. Use a password manager and generate unique passwords for every account. Enable two-factor authentication on everything that matters.

Keep software updated. Outdated WordPress installations, unmaintained plugins, old PHP versions — these are the entry points for most small business website compromises.

Back up everything. Daily automated backups of your website and critical business data, stored somewhere separate from your main systems.

Secure your email. Without SPF, DKIM, and DMARC records on your domain, anyone can send emails appearing to come from your business.

Train your team. Most breaches start with a phishing email.

The one thing most small businesses skip

Security testing. Implementing the measures above reduces your exposure significantly. But without testing you have no way of knowing whether your website currently has vulnerabilities despite your best efforts.
