The Benefits of Cyber Essentials for Your Business

Is Cyber Essentials Certification Worth It?

Cyber security can feel complicated.

Businesses are regularly advised to invest in antivirus protection, multifactor authentication, firewalls, backups, monitoring, employee training and many other security measures.

While all these areas can be important, business owners may struggle to understand which improvements should be prioritised first.

Cyber Essentials provides a clear starting point.

It is a UK government-backed certification scheme designed to help organisations protect themselves against common cyber attacks. The National Cyber Security Centre describes Cyber Essentials as the minimum cyber security standard it recommends for organisations of every size.

Achieving certification can help improve your security, reassure customers and demonstrate that your business has taken practical steps to protect its systems and information.

What is Cyber Essentials?

Cyber Essentials is a cyber security certification scheme supported by the UK Government and overseen by the National Cyber Security Centre.

The scheme focuses on five important technical controls:

• Firewalls
• Secure configuration
• Security update management
• User access control
• Malware protection

These controls were selected because they can make a significant difference against common internet-based attacks. The NCSC has explained that its analysis of real cyber incidents found that one or more of these five controls could have stopped the attacks from progressing.

Cyber Essentials is available to organisations of different sizes and sectors, including:

• Small businesses
• Charities
• Schools
• Professional services
• Manufacturers
• Retailers
• Public-sector suppliers
• Large organisations

It is intended to create a practical baseline rather than requiring every organisation to implement the same complex security programme as a bank or government department.

What does Cyber Essentials protect against?

Cyber Essentials is designed to reduce exposure to common attacks carried out using widely available tools and techniques.

These may include:

• Malware
• Ransomware
• Password attacks
• Exploitation of unpatched software
• Unauthorised access
• Attacks against exposed internet services
• Malicious software installed through insecure settings

It does not guarantee that your business will never experience a cyber incident.

A determined attacker may use advanced techniques, stolen employee credentials, social engineering or vulnerabilities that are not yet publicly known.

However, many successful cyber attacks do not depend on advanced hacking.

They succeed because an organisation has missed basic protections such as installing security updates, removing unused administrator accounts or changing insecure default settings.

Cyber Essentials helps make sure these fundamental areas are addressed consistently.

Benefit 1: Reduce the risk of common cyber attacks

The most important benefit of Cyber Essentials is improved protection.

The certification process requires the business to review its computers, servers, cloud services, mobile devices, firewalls and software.

This can identify problems such as:

• Unsupported operating systems
• Missing security updates
• Employees with unnecessary administrator access
• Weak firewall configurations
• Unused applications
• Insecure remote-access services
• Antivirus protection that is not properly enabled
• Default passwords that have not been changed

These are common weaknesses that cyber criminals actively search for.

The NCSC describes Cyber Essentials as a proven, government-backed standard that significantly reduces exposure to common attacks.

Insurance data cited by the NCSC and IASME indicates that organisations with current Cyber Essentials certification are 92% less likely to make a cyber insurance claim than organisations without certification. This does not mean incidents become impossible, but it provides evidence that implementing the controls can make a meaningful difference.

Benefit 2: Create a clear cyber security starting point

Many businesses know that their security should improve but do not know where to begin.

Cyber Essentials gives the organisation a defined list of requirements rather than a vague instruction to “be more secure”.

The five controls help the business focus on practical questions:

• Are our computers securely configured?
• Is unsupported software still being used?
• Are important security updates installed promptly?
• Do employees have more access than they need?
• Is malware protection enabled and monitored?
• Are our internet connections protected by suitable firewalls?

This creates a structured improvement process.

Even when a business does not pass its first assessment, preparing for certification can reveal weaknesses that may otherwise have remained unnoticed.

The process turns cyber security into a measurable business project with clear actions and responsibilities.

Benefit 3: Improve security update management

Cyber criminals frequently exploit known software vulnerabilities.

In many cases, the manufacturer has already released an update, but the organisation has not installed it.

Cyber Essentials requires businesses to manage updates across supported operating systems, applications, network devices and other in-scope software.

This encourages the business to identify:

• Which devices are missing updates
• Which applications are no longer supported
• Which users repeatedly postpone updates
• Which network devices require firmware updates
• Which systems cannot be updated without further work
• Who is responsible for resolving update failures

Unsupported software within the assessment scope can prevent an organisation from achieving certification.

This can provide a useful reason to replace old systems that have remained in use because upgrading them was repeatedly delayed.

It also encourages businesses to create a repeatable update process rather than relying on employees to decide when updates should be installed.

Benefit 4: Reduce unnecessary administrator access

Administrator access gives a user greater control over a computer or cloud system.

It may allow them to:

• Install applications
• Change important settings
• Disable security tools
• Create new accounts
• Access other users’ information
• Run powerful scripts
• Remove software

Employees may be given administrator access because it appears convenient.

However, if their account or computer is compromised, malicious software may receive the same level of access.

Cyber Essentials requires organisations to control privileged access and ensure users receive only the permissions they need.

Preparing for certification can help uncover:

• Employees with permanent local administrator rights
• Old administrator accounts
• Shared administrator credentials
• Former suppliers who still have access
• Employees using administrator accounts for everyday work
• Privileges that were granted temporarily but never removed

Reducing unnecessary permissions can limit the damage caused by malware, stolen credentials and employee mistakes.

Benefit 5: Improve the configuration of business devices

Computers and applications often include features that are unnecessary for most employees.

Unused services, applications and accounts create additional opportunities for attack.

Secure configuration involves reducing these opportunities by making sure devices are set up appropriately.

This may include:

• Removing unused applications
• Disabling unnecessary services
• Changing default passwords
• Blocking automatic execution of untrusted files
• Restricting removable storage
• Removing unused user accounts
• Configuring device-locking policies
• Disabling insecure protocols

The NCSC describes secure configuration as setting up computers securely to minimise the routes a cyber criminal can use to gain access.

This is particularly valuable for businesses where computers have been installed at different times and configured by different people.

Cyber Essentials encourages the organisation to move towards a consistent and documented security standard.

Benefit 6: Strengthen firewall and internet security

Firewalls create a controlled boundary between your systems and other networks, including the internet.

A firewall can help prevent unauthorised connections from reaching computers, servers and business applications.

However, simply owning a firewall does not mean it has been configured securely.

Cyber Essentials encourages the business to review:

• Internet-facing services
• Firewall rules
• Remote-access settings
• Default administrator passwords
• Unnecessary open ports
• Management interfaces
• Home and remote-working equipment
• Cloud-based firewalls

An old rule may have been created for a temporary project and never removed.

A server-management page may have been accidentally exposed to the internet.

Remote Desktop may have been enabled without appropriate protection.

Certification preparation provides an opportunity to find and correct these problems before an attacker discovers them.

Benefit 7: Improve malware and ransomware protection

Cyber Essentials requires suitable protection against malware.

Depending on the devices and environment, this may involve:

• Antivirus protection
• Application allow-listing
• Restrictions on untrusted applications
• Mobile application controls
• Browser and operating-system security
• Protection against malicious scripts

The aim is to reduce the likelihood of unauthorised software running on business devices.

This can help protect against:

• Viruses
• Ransomware
• Spyware
• Credential-stealing software
• Remote-access malware
• Malicious downloads

Cyber Essentials alone is not a complete ransomware strategy.

Businesses still need secure backups, multifactor authentication, employee training, monitoring and an incident response plan.

However, the five Cyber Essentials controls can prevent many of the common weaknesses ransomware groups use to gain their initial access.

Benefit 8: Demonstrate that you take cyber security seriously

Customers increasingly want to know that suppliers can protect the information entrusted to them.

They may ask questions such as:

• How are your computers protected?
• Do you install security updates?
• How is employee access controlled?
• Do you use supported software?
• Do you have an independent cyber security certification?

Cyber Essentials provides a recognised answer.

Certification demonstrates that your organisation has implemented an established set of baseline controls and completed an assessment through an authorised certification body.

IASME states that certification can help organisations publicly demonstrate their commitment to cyber security and build trust with customers, suppliers and other stakeholders.

This may be particularly valuable if your business handles:

• Customer personal information
• Financial records
• Confidential documents
• Intellectual property
• Supplier data
• Employee records
• Access to customer systems

The certificate does not prove that every possible security risk has been removed.

It does provide credible evidence that your business has taken important precautions.

Benefit 9: Improve customer and supplier confidence

Cyber security is not only an internal issue.

A compromise affecting one supplier can create problems throughout a supply chain.

For example, attackers may compromise a small supplier and then use its email accounts or remote access to target larger customers.

Businesses are therefore increasingly reviewing the security of organisations that process information or connect to their systems.

The NCSC promotes Cyber Essentials as a practical way for organisations to gain confidence that suppliers have implemented important technical protections.

Holding certification may help your business complete:

• Supplier security questionnaires
• Customer due-diligence checks
• Contract reviews
• Tender applications
• Insurance applications
• Partnership assessments

Instead of only stating that your business has good security, you can provide evidence through a recognised certification.

Benefit 10: Access certain government contracts

Cyber Essentials can open opportunities for organisations that want to work with government or public-sector bodies.

UK government procurement policy requires Cyber Essentials or Cyber Essentials Plus certification—or evidence of equivalent controls—before certain contracts can be awarded. This applies particularly where the supplier will handle sensitive or personal information or provide certain technology-related services.

Other organisations may voluntarily require Cyber Essentials from their suppliers even when it is not a formal government requirement.

Achieving certification before a tender is published can prevent delays and allow the business to respond more confidently to opportunities.

Waiting until a customer requires the certificate may create pressure to make security changes quickly.

Benefit 11: Potentially improve your competitive position

When two suppliers offer similar services, security can influence the customer’s decision.

A company with Cyber Essentials certification may be able to demonstrate that it has:

• Reviewed its security controls
• Removed unsupported software
• Restricted administrator access
• Managed security updates
• Protected devices from malware
• Completed an independent certification process

This may help distinguish the business from competitors that cannot provide comparable evidence.

Certification is not a substitute for good service, pricing or experience.

However, it can become an additional reason for security-conscious customers to choose your organisation.

Benefit 12: Receive cyber insurance with qualifying certification

Qualifying organisations can receive cyber liability insurance as part of Cyber Essentials certification.

IASME states that UK-domiciled organisations with turnover below £20 million can be eligible when the certification covers the whole organisation. Current scheme information describes £25,000 of cyber insurance cover and access to incident response services for qualifying organisations.

Eligibility conditions apply, so businesses should review the policy wording and should not assume that the included cover will meet every insurance requirement.

Larger organisations or businesses with higher risks may need additional cyber insurance.

The included cover is still a useful benefit, particularly for smaller organisations obtaining certification for the first time.

More importantly, the security improvements required for certification may help reduce the likelihood of needing to make a claim.

Benefit 13: Improve accountability within the business

Cyber security responsibilities can become unclear.

The IT provider may assume the business is approving updates, while the business assumes the provider is managing everything.

Employees may believe somebody else is reviewing administrator access or monitoring antivirus protection.

Cyber Essentials requires the organisation to understand and confirm how its controls are being managed.

This helps identify:

• Who manages security updates
• Who approves administrator access
• Who monitors malware protection
• Who manages firewalls
• Who keeps the hardware and software inventory
• Who checks whether systems remain supported
• Who is responsible for maintaining compliance

The Cyber Essentials assessment includes a declaration by a board member or director, reinforcing that cyber security is a business responsibility rather than something that can be left entirely to the IT department.

Benefit 14: Identify unknown or forgotten devices

Before applying for Cyber Essentials, a business needs to understand the technology included within the assessment.

This may uncover:

• Old laptops
• Forgotten servers
• Personal devices accessing company information
• Unsupported mobile phones
• Home routers used for business work
• Unmanaged cloud services
• Old firewall appliances
• Test systems that were never removed
• Devices belonging to former employees

You cannot effectively protect systems you do not know exist.

Creating a reliable inventory is one of the practical benefits of preparing for certification.

It can also improve future support, budgeting, software licensing and equipment replacement.

Benefit 15: Support a wider compliance programme

Cyber Essentials can support broader security, privacy and compliance work.

For example, the controls may help an organisation improve areas relevant to:

• UK GDPR security obligations
• Supplier assurance
• Contractual security requirements
• Cyber insurance
• Internal risk management
• Industry-specific compliance

However, Cyber Essentials certification does not automatically prove compliance with every law or regulatory standard.

It focuses on a specific set of technical protections against common internet-based attacks.

The business may still need additional measures covering:

• Data retention
• Privacy notices
• Incident reporting
• Employee training
• Physical security
• Business continuity
• Backups
• Risk assessments
• Security monitoring
• Industry-specific requirements

Cyber Essentials is best treated as a strong foundation rather than the final stage of your cyber security programme.

What is the difference between Cyber Essentials and Cyber Essentials Plus?

There are two levels of certification.

Cyber Essentials

Cyber Essentials is based on a verified self-assessment questionnaire.

The organisation answers questions covering the five technical controls.

A qualified assessor reviews the answers, and a board member or director confirms that the information provided is accurate. The standard assessment does not include a vulnerability scan or full technical audit.

This level may be suitable for businesses that want to:

• Establish a recognised security baseline#
• Demonstrate good cyber security practices
• Meet a contractual requirement
• Begin improving their security
• Prepare for Cyber Essentials Plus

Cyber Essentials Plus

Cyber Essentials Plus uses the same five technical controls but adds an independent technical audit.

The assessor tests a sample of systems and carries out checks that can include internal and external vulnerability assessments, user-device testing, internet gateway checks and testing of relevant servers.

Cyber Essentials Plus provides a higher level of assurance because the implementation of the controls is technically tested rather than relying only on the verified questionnaire.

It may be appropriate where:

• Customers require stronger evidence
• The business handles sensitive information
• Certification is required for a contract
• The organisation wants independent technical testing
• The business operates within a security-conscious supply chain
• Does Cyber Essentials certification expire?

Cyber Essentials and Cyber Essentials Plus certificates are valid for 12 months.

They must be renewed annually for the organisation to remain certified.

Annual renewal is important because technology changes.

During a year, a business may:

• Recruit new employees
• Replace computers
• Introduce new applications
• Change its firewall
• Move services into the cloud
• Open another office
• Allow more remote working
• Change IT providers
• Acquire another company

A configuration that was compliant last year may not remain compliant automatically.

The objective should be to maintain the controls throughout the year rather than making temporary improvements immediately before renewal.

Does Cyber Essentials guarantee that your business is secure?

No certification can guarantee complete protection.

Cyber Essentials addresses a specific set of common threats and technical controls.

It does not replace:

• Secure backups
• Disaster recovery
• Security awareness training
• Email threat protection
• Multifactor authentication
• Continuous monitoring
• Penetration testing
• Incident response planning
• Data-loss prevention
• Supplier risk management
• Advanced threat detection

The NCSC explains that Cyber Essentials was designed around common internet-based attacks using publicly available capabilities.

A business facing more advanced or specialist risks may require additional controls.

However, advanced security tools provide limited value when the basic protections have not been implemented.

Cyber Essentials helps make sure the foundations are in place.

What are the common challenges?

Businesses may encounter problems when preparing for certification.

Common examples include:

• Unsupported operating systems
• Old software that cannot be updated
• Employees with local administrator access
• Personal devices accessing company data
• Unmanaged home-working equipment
• Incomplete device records
• Firewall passwords that have not been changed
• Updates that are not centrally managed
• Antivirus protection that is inconsistent
• Suppliers with undocumented access
• Devices that are no longer reporting

Some organisations discover that an important legacy application requires an unsupported operating system.

Others find that employees have been using personal devices without formal approval.

These issues may require planning, investment and changes to working practices.

The assessment is not intended simply to create paperwork.

Its value comes from identifying and correcting the underlying security problems.

How should your business prepare?

A sensible preparation process could include:

• Define which parts of the organisation will be included.
• Create an inventory of devices, software and cloud services.
• Identify unsupported systems.
• Review firewall and remote-access settings.
• Confirm security updates are centrally managed.
• Remove unnecessary administrator permissions.
• Check malware protection is active.
• Review employee-owned devices.
• Correct any non-compliant systems.
• Complete the assessment questionnaire carefully.
• Maintain supporting evidence.
• Create a process for staying compliant throughout the year.

The NCSC provides free preparation resources, including assessment questions and a readiness tool that produces a tailored action plan.

Businesses that need technical assistance can also work with a qualified certification body or an NCSC-assured Cyber Advisor.

Is Cyber Essentials worth it?

For many small and medium-sized businesses, Cyber Essentials is a worthwhile investment.

It can help your organisation:

• Reduce its exposure to common cyber attacks
• Improve device and software management
• Remove unnecessary administrator access
• Identify unsupported systems
• Strengthen malware and firewall protection
• Demonstrate a commitment to security
• Build trust with customers
• Meet supplier requirements
• Bid for certain contracts
• Access included cyber insurance when eligible
• Create a foundation for further security improvements

The greatest benefit is not the certificate or logo.

The real value comes from the security improvements the organisation makes while preparing for and maintaining certification.

A business should not aim only to pass the questionnaire.

It should aim to understand the controls, apply them properly and keep them working throughout the year.
