Cyber Essentials Certification Support
Helping businesses protect themselves from common cyber threats
Cyber Essentials is a UK Government-backed cyber security certification designed to help businesses protect themselves against common online threats. It is recommended by the National Cyber Security Centre and focuses on five key security controls that reduce the risk of cyber attacks.
At Sigma Office Ltd, we help businesses understand, prepare for and achieve Cyber Essentials certification with practical IT support, clear guidance and hands-on remediation.
What is Cyber Essentials?
Cyber Essentials helps demonstrate that your business has basic cyber security measures in place.
The certification focuses on areas such as:
- Firewalls and internet gateways
- Secure configuration of devices and software
- User access control
- Malware protection
- Security updates and patching
- Multi-factor authentication for cloud services
The current Cyber Essentials requirements are reviewed regularly, with version 3.3 effective from 27 April 2026.
Why Cyber Essentials matters
Cyber Essentials can help your business:
- Reduce the risk of common cyber attacks
- Demonstrate good security practice to clients and suppliers
- Meet tender or contract requirements
- Support cyber insurance discussions
- Build trust with customers
- Improve internal IT security
Some organisations now expect suppliers to hold Cyber Essentials, especially when handling sensitive, personal or financial information.
Cyber liability insurance
Eligible UK organisations that achieve Cyber Essentials certification may also receive cyber liability insurance as part of the scheme, subject to the scheme’s terms and eligibility criteria.

For managed IT support clients

In many cases, only a small number of improvements may be needed before the business is ready to apply.
