The UK government-backed Cyber Essentials certification is no longer a “nice to have”—it’s rapidly becoming the baseline cybersecurity standard for SMEs, supply-chain contractors, and public sector partners. With ransomware attacks and phishing threats growing in sophistication, businesses need a simple yet effective framework to keep data, systems and clients safe. That’s where Cyber Essentials steps in.

What is cyber essentials and why your business need it in 2025

1. What is Cyber Essentials?

Cyber Essentials is a government-endorsed certification scheme developed by the UK’s National Cyber Security Centre (NCSC). It outlines five core security controls that, when properly implemented, can protect businesses against the most common cyber threats. The scheme is designed specifically for SMEs and mid-sized organisations—not just large enterprises.

2. Why was Cyber Essentials introduced?

Many businesses—especially those under 250 employees—lack dedicated IT security staff. As a result, they’re vulnerable to avoidable issues like phishing scams, malware infections, weak passwords and outdated software. Cyber Essentials was created to:

• Set a minimum baseline for cyber hygiene.

• Help businesses avoid 80% of common cyberattacks.

• Build trust with suppliers, clients, and regulators.

3. What does Cyber Essentials cover?

The scheme focuses on five core technical controls:

a) Secure Configuration

Devices and software must be set up to reduce vulnerabilities—this includes removing unused accounts, changing default passwords and limiting user permissions.

b) Firewalls and Internet Gateways

All devices should be protected by firewalls to filter out malicious traffic. This applies to laptops, desktops, and mobile devices whether on-site or remote.

c) Access Control

Only users who need access to a system or data should have it. Admin privileges should be tightly restricted and regularly reviewed.

d) Patch Management

All software must be updated regularly to close known vulnerabilities. This includes operating systems, applications, and even firmware.

e) Malware Protection

Anti-virus and anti-malware tools must be installed and actively maintained across all endpoints.

5. What’s in it for your business?

Here’s what Cyber Essentials brings to the table beyond just a certificate:

a) Demonstrated Commitment to Cyber Hygiene

It shows clients, insurers and partners that your business takes cybersecurity seriously—even if you’re not ISO 27001 certified.

b) Competitive Advantage

Many government tenders now require Cyber Essentials certification. Increasingly, so do large corporations across supply chains.

c) Reduced Cyber Insurance Premiums

Several insurers offer discounts to businesses with Cyber Essentials certification, recognising it as evidence of a lower risk profile.

d) Protection Against Basic Threats

You reduce your exposure to phishing, ransomware, and data leaks by 80% when you implement the five core controls properly.

e) Confidence in Remote Working

Cyber Essentials standards apply regardless of where your teams work. This helps secure devices used by remote or hybrid staff.

6. Do you need cyber essentials?

In a word—yes. Here’s who benefits most:

• SMEs and mid-sized firms needing a security benchmark.

• Contractors bidding for UK public sector work (MoD, NHS, councils).

• Firms handling customer data, especially under GDPR and NIS2.

• Professional services firms (legal, finance, insurance).

• Manufacturing and logistics businesses working in digital supply chains.

Note: Even if you’re based in Ireland and not subject to UK procurement rules, having Cyber Essentials can still help when dealing with UK clients or data subjects.

7. Common Misconceptions Debunked

Myth – “Cyber Essentials is only for big firms.”

• Reality – It was designed for SMEs.

Myth – “It’s just a tick-box exercise.”

• Reality – Certification is reviewed by a trained assessor and must be renewed annually.

Myth – “We already have antivirus, so we’re covered.”

• Reality – AV is just one of five controls—and not the strongest.
