Does your small business need cyber security?

Reflective IT cyber security expert supporting a small business owner

Yes. Almost half of UK small businesses (46%) identified a cyber breach or attack in the last 12 months, according to the government's Cyber Security Breaches Survey 2025/26. Phishing was by far the most common attack, hitting 38% of businesses. Yet only 12% of small businesses hold Cyber Essentials, the UK government-backed baseline.

Attackers often target small businesses because gaps such as a reused password, a mailbox without multi-factor authentication, a laptop that missed its updates or an invoice email nobody questioned make them easy targets. Those gaps are cheap to close, and closing them is what we do.

To understand these risks and get practical steps to reduce them, read our guide to cyber security for SMEs.

Benefits of cyber security for small businesses

Strong cyber security keeps your systems and data secure, protects your reputation and helps keep your business running.

Data Protection

Keep customer, financial and staff records safe from theft, loss and unauthorised access. It's the information your business runs on, and the first thing attackers go after.

Fraud Prevention

Stop fake invoices and hijacked mailboxes before money leaves the account. Payment fraud is one of the most common and costly attacks on small firms.

Office 365 Backup

Ransomware or a major outage can stop a small business trading for days. Protected systems and tested backups mean you're back up and running quickly.

Winning and Keeping Clients

Clients, tenders and supply chains now ask for Cyber Essentials. Certification shows you protect their data and helps you answer security questionnaires with confidence.

Cyber Insurance

Insurers increasingly expect MFA, patching and backups before they'll offer or renew cover. Meeting those requirements keeps your policy valid and premiums in check.

Legal Compliance

UK GDPR requires appropriate security for the personal data you hold, and the ICO can fine businesses that fall short. Sector rules from bodies such as the FCA and SRA add more.

Secure Remote Working

Staff working from home or on the move get the same protection as the office, whatever device or network they connect from.

Cost Control

Preventing an attack costs far less than recovering from one. A managed service also avoids the cost of recruiting and keeping an in-house security team.

Why small businesses put off cyber security

Antivirus covers one of the five Cyber Essentials controls. Many breaches start with a stolen password or convincing email, which MFA, email security and staff training help stop.


Much of the protection you need is already in your Microsoft 365 licences. We switch that on first, then add only the controls your business needs.


Most attacks are automated, and phishing and password-guessing tools target every business they find. 42% of UK micro businesses reported a breach or attack last year.


We run the gap analysis, fix what needs fixing and support your submission, so you can go back to them with a certificate in hand.

Frequently asked questions

Yes. 46% of UK small businesses identified a breach or attack in the last year (Cyber Security Breaches Survey 2025/26). Most attacks are automated and don't check how big a business is.

At a minimum, you need the five Cyber Essentials controls (firewalls, secure configuration, access control, malware protection and security updates), plus backups and staff training to stop phishing.

Costs depend on your users, devices and the controls you need. A free Microsoft 365 security assessment gives you a clear, fixed quote before any work begins.

Start by switching on the security already in your Microsoft 365 licences, then add only the controls needed to close your most important gaps.

It's the right baseline, and clients and insurers often ask for it. But it proves your controls on one day. Managed security keeps them in place for the rest of the year.

Usually not. Antivirus covers one control, and most breaches start with a stolen password or a phishing email. IT support keeps systems working; security stops attacks getting in.

No. Most protection runs in the background. Conditional Access can reduce sign-in prompts on trusted devices, so security doesn't get in the way of the working day.

Yes. Intune, Defender and Cisco Umbrella protect devices wherever they connect, so home and hybrid workers get the same protection as the office.

Yes. Insurers increasingly expect MFA, managed device protection, patching and backups. We put those in place and give you the evidence for your renewal.

Call us. Business-stopping issues get a 30-minute first response target. Where needed, 24/7 SOC monitoring spots and contains threats around the clock.

Yes. Start with the essential controls, then add device management, backups, training or 24/7 SOC monitoring as your needs grow, without changing provider.
