If you need help with this form, please contact us.

ISO 27001, the Information Security Management Standard, is increasingly essential for safeguarding organisational and customer information.

This guide offers a comprehensive overview of the standard, exploring its workings, benefits and growing popularity. It serves as a starting point for understanding why ISO 27001 can be a vital tool for managing information security risks and how organisations can achieve certification.

What is ISO 27001?

ISO/IEC 27001:2022, known as ISO 27001, is the standard developed by the International Organisation for Standardization (ISO) and the International Electrotechnical Commission (IEC) that addresses Information Security Management. It provides an extensive set of requirements for managing sensitive company information, supporting its security and integrity.

While ISO 27001 may not have the same long-standing history as ISO 9001 or ISO 14001, it has become one of the most in-demand standards in recent years. As cyber threats continue to rise, more organisations are turning to ISO 27001 to help them manage information security risks and put robust controls, policies, and procedures in place to protect their data.

What is an Information Security Management System (ISMS)?

An ISMS is a set of comprehensive policies and processes that enable organisations to handle sensitive information securely.

Establishing these processes helps organisations to manage the risk of data being mishandled, destroyed, or lost. An ISMS also outlines the steps to combat errors and analyse incidents to reduce the likelihood of recurrence.

To simplify this, an Information Security Management System (ISMS) is like your organisation’s security playbook, a set of written rules and step‑by‑step procedures that guide everyone on how to classify, store, share, and protect sensitive data such as customer records or financial reports. It helps you identify and prioritise risks by deciding whether to focus on encrypting emails or strengthening physical security, and also includes regular checks, such as audits and scans, to ensure those rules are followed.

If something does go wrong, the ISMS defines how to detect the incident, who to notify, and how to respond and learn from it, so that the same error does not happen again.

How does ISO 27001 manage information security risks?

ISO 27001 requires organisations to systematically assess any risks to their information security and implement policies and procedures to manage those risks.

This proactive approach helps organisations to anticipate potential threats and implement preventive measures, helping them to be well-prepared to handle security incidents and mitigate their impact.

It provides a structured approach for managing information security risks in accordance with defined objectives and obligations.

Why is ISO 27001 important for organisations?

ISO 27001 is crucial for organisations as it helps protect data assets and meet compliance objectives. By adopting a risk-based approach to information security management, ISO 27001 addresses specific information security threats and covers people, processes and technology.

This standard is important not only for large corporations but also for SMEs and charities, which are equally vulnerable to cyber attacks and data breaches.

What are the benefits of ISO 27001 certification?

Achieving ISO 27001 certification can offer numerous advantages for businesses, including:

• Plugging security gaps: Regular internal reviews, also known as gap analyses, and audits help identify and address weaknesses in security systems.
• Reducing risks of cyber attacks: Robust security measures reduce the likelihood of successful cyber attacks.
• Demonstrating regulatory compliance: Certification supports your organisation’s efforts to meet information security requirements and align with regulations such as GDPR.
• Gaining a marketing edge: ISO 27001 certification can enhance credibility and provide a competitive advantage in winning new business.
• Winning contracts or government tenders: ISO 27001 can be the difference between winning and losing vital contracts, especially in the public sector where data security is paramount.

How does ISO 27001 help plug information security gaps?

Part of implementing ISO 27001 includes conducting a gap analysis to identify areas that do not currently meet the standards of a quality Information Security Management System.

Regular internal audits assess information security measures and highlight areas for improvement, helping organisations identify any opportunities for improvement.

How does ISO 27001 reduce cyber attack risks?

With an ISMS in place, organisations can take a structured approach to identifying and managing cyber security risks before they develop into serious incidents.. This proactive stance reassures both potential and existing customers that the organisation is committed to staying ahead of any risks to their sensitive information.

“Achieving ISO 27001 has been crucial for winning tenders in the government sector where data security is of paramount importance. Security is our most important feature and we take it very seriously” – SmartSurvey, a British Assessment Bureau client.

How does ISO 27001 demonstrate regulatory compliance?

ISO 27001 certification is internationally recognised and supports an organisation’s efforts to meet information security requirements. It aligns with regulations such as UK General Data Protection Regulation (GDPR) and the Data Protection Act, offering stakeholders and regulators assurance of the organisation’s commitment to data security.

Will an ISMS help me comply with UK GDPR?

Yes, an ISMS plays a key role in supporting compliance with the UK GDPR. It provides a structured approach to managing data security, helping to prevent breaches and protect personal information.

In fact, many organisations that handle personal data or offer technology services are expected by clients and partners to hold ISO/IEC 27001 certification, as it demonstrates a clear commitment to GDPR compliance and strong data protection practices.

Does ISO 27001 guarantee legal compliance with UK GDPR or the Data Protection Act?

While ISO 27001 provides a robust approach for securing information, it does not automatically guarantee full legal compliance with UK GDPR or the Data Protection Act.

Organisations must meet additional legal requirements specific to UK GDPR, which may extend beyond the scope of ISO 27001.

However, ISO 27001 was not designed to make your organisation automatically compliant with any particular piece of information security legislation. Therefore, while an ISMS will help your organisation implement ways to manage information security risks, GDPR places a few additional requirements upon your organisation.

For comprehensive guidance on complying with UK GDPR, you can refer to the official UK Government website.

How do I get ISO 27001 certification?

To achieve ISO 27001 certification, organisations must demonstrate an effective ISMS that meets the standard’s key requirements.

This involves providing documented evidence of processes such as risk assessments, security policies and management reviews.

Achieving your certification involves demonstrating that you have put into place the necessary processes for an ISMS that meets the requirements of ISO 27001.

What documents are required for ISO 27001?

Key documents required for ISO 27001 certification include:

• Scope of the ISMS
• Information security policy and objectives
• Risk assessment and risk treatment methodology
• Statement of Applicability
• Risk Treatment Plan
• Definition of security roles and responsibilities
• Inventory of assets
• Access control policy
• Operating procedures for IT management
• Incident management procedure
• Business continuity procedures
• Records of training and skills
• Internal audit programme and results
• Management review results

What is the ISO 27001 certification process?

The certification process involves two main audits:

Stage 1 Audit: The Stage 1 audit involves a thorough review of documented processes to evaluate compliance with ISO 27001 requirements.

It identifies any nonconformities that need to be addressed by the business before moving to the Stage 2 Audit.

Stage 2 Audit: In the Stage 2 Audit, the effectiveness of the ISMS is assessed in practice.

Auditors review internal audits, management reviews, and evidence of implementation to confirm compliance with ISO 27001 requirements.

If all nonconformities are addressed within the required timeframe, the organisation may be recommended for certification.

Read our ISO 27001 Checklist for a 10-step breakdown of the ISMS implementation journey.

What are nonconformities and how are they addressed?

Nonconformities are areas where an organisation does not meet the requirements of ISO 27001. To move forward with certification, organisations must create corrective action plans to address these issues.

Nonconformities are typically classified as either major or minor. Major nonconformities must be addressed immediately, as they can prevent certification. Minor nonconformities still require attention, but they can often be reviewed at the next assessment, provided there is evidence that corrective action is underway.

How long does ISO 27001 certification last?

ISO 27001 certification is valid for three years, requiring annual surveillance audits to verify continued compliance.

After three years, organisations must undergo a recertification process to maintain their certificate.

What are annual surveillance audits?

Surveillance audits are conducted annually to verify ongoing compliance with the ISO 27001 standard. These audits sample different parts of the ISMS to verify the system remains effective and up-to-date with evolving security threats.

One reason ISO 27001 has such an excellent reputation is the requirement for continual improvement. As part of this, your certification body will conduct annual audits to confirm that your ISMS continues to meet the requirements of ISO 27001.

What is the ISO 27001 recertification process?

Recertification involves a comprehensive review of the ISMS every three years to confirm continued adherence to ISO 27001 requirements.

This process reaffirms an organisation’s commitment to maintaining high information security standards.

These annual assessments help you to prepare for recertification, a process you’ll undergo every three years to refresh your ISO 27001 certification and affirm to your customers that your UKAS-accredited certification is being regularly reviewed and maintained.

How much does ISO 27001 certification cost?

The cost of ISO 27001 certification is influenced by a number of factors.

Certification bodies typically charge based on the time required for assessments, with potential savings for multi-site organisations through sampling.

What factors affect ISO 27001 costs?

Key factors influencing ISO 27001 costs include:

• Staff numbers
• Industry sector
• Complexity and risk level
• Number of sites

Understanding these factors helps organisations budget appropriately for certification.

Can multi-site organisations reduce audit costs?

In some cases, multi-site organisations may reduce costs by sampling sites within the certification cycle, rather than auditing each site individually.

This approach could help to minimise audit expenses without compromising compliance. However, sampling is only applicable in certain scenarios.

How long does the certification process take?

The duration of the certification process varies based on the organisation’s size and complexity.

Smaller entities may require fewer days for assessment, while larger organisations may need more extensive evaluations that could last weeks.

Are there hidden or ongoing certification costs?

Organisations should be aware of potential hidden costs, such as management and travel fees, and look for transparency in contractual terms with certification bodies.

A clear understanding of the full scope of costs could help prevent unexpected expenses during the certification process.

What role does leadership play in certification?

Leadership is crucial for driving ISO 27001 initiatives.

Senior management must support and empower an ‘ISO champion’ within the business, responsible for coordinating the implementation and maintenance of the ISMS. An engaged leadership team sets the tone for a security-conscious culture, ensuring that everyone in the organisation understands the importance of information security.

What is the function of an ‘ISO champion’?

An ISO champion is a vital figure within the organisation, tasked with overseeing the ISMS and ensuring compliance with ISO 27001 requirements.

This individual coordinates efforts across departments, fostering a collaborative approach to security management.

By driving awareness and engagement, the ISO champion helps embed security practices into everyday operations, ensuring the organisation remains resilient against emerging threats.

You may choose to nominate an ISO champion with a mandate to implement the ISMS, as directed by the senior management team.

What types of information need to be protected?

Organisations need to protect a wide range of information, including customer data, intellectual property, internal processes, employee details, payments, and trade secrets.

Understanding what needs protection is vital for effective information security management.

This comprehensive approach helps businesses to shield all valuable assets from potential threats, maintaining an organisation’s integrity and reputation. It’s also important to understand exactly what must be protected and why.

Why is continual improvement important for ISO 27001?

A commitment to continual improvement is essential for maintaining and improving the ISMS, as it supports efforts to prevent potential security breaches and maintain certification.

Organisations should continually enhance their ISMS to uphold high information security standards.

Regular reviews and updates to policies and procedures help address emerging risks and vulnerabilities, facilitating the ISMS’s adaptation to the evolving security landscape. It is vital that your business remains dedicated to the principles of ISO 27001 to maintain certification.

Should I use a consultant to get certified?

Consultants can provide valuable support, especially for small businesses with limited resources. They offer expertise in navigating the complexities of ISO 27001, helping organisations implement effective security measures.

However, organisations should avoid over-reliance on external assistance to ensure team participation and internalisation of security practices. A consultant is often used for very different reasons, depending on the size of the organisation.

As an accredited certification body, we do not provide consultancy services or implementation advice. This allows us to remain impartial throughout the audit process, ensuring the integrity and credibility of your ISO certification.

Find the right ISO consultant for your organisation.

What are the risks of over-relying on a consultant?

Over-reliance on consultants may hinder team participation, limiting the long-term benefits of ISO 27001.

While a consultant may help overcome short-term challenges, organisations miss the opportunity to embed security practices internally. It’s crucial to strike a balance, ensuring that the consultant’s knowledge is transferred to the organisation’s team, empowering them to maintain and improve the ISMS independently.

Relying on third parties has its dangers. While a consultant may help a business to overcome short-term challenges, there’s a risk that long-term dependency could negate the cost-benefit of implementing ISO 27001.

How do I choose a qualified ISO 27001 consultant?

When selecting a consultant, organisations can consider sector-specific experience, impressive credentials, and auditing expertise.

A qualified consultant can provide effective guidance during the certification process, ensuring successful implementation of ISO 27001.

It is important to choose a consultant with a proven track record of helping organisations achieve and maintain certification, as well as those who offer tailored solutions that align with your specific needs and objectives.

Can SMEs implement ISO 27001 without a consultant?

Smaller businesses can certainly implement and achieve ISO 27001 certification without external assistance, however, third-party expertise may be beneficial for resource-limited organisations.

A cost-benefit analysis could be crucial to determining the best approach.

How do I choose the right certification body?

Choosing the right certification body is crucial for implementing an ISMS and achieving ISO 27001 certification.

A UKAS-accredited certification body can provide credibility and recognition for your ISO 27001 certification. UKAS accreditation signals high standards and independent verification, enhancing the effectiveness of your certification.

A reputable certification body can provide clear guidance, support throughout the certification process, and a commitment to maintaining impartiality and integrity.

Choosing the right certification body doesn’t just make it easier to implement an ISMS and achieve ISO 27001 – it can also boost the effectiveness of your certification when it comes to retaining existing customers and winning new business.

What are the advantages of UKAS-accredited certification?

UKAS-accredited certifications are independently verified, demonstrating adherence to the highest standards. This provides a competitive edge over self-certified or non-accredited certificates, showing a commitment to excellence in information security management.

The credibility of UKAS accreditation enhances trust among customers, partners, and stakeholders, positioning your organisation as a leader in information security.

ISO 27001 certification issued by UKAS-accredited certification providers like British Assessment Bureau helps you to demonstrate a much higher level of information security than your competitors.

Why is UKAS certification more credible than non-accredited certificates?

UKAS-accredited certifications are recognised internationally, providing assurance of competence and credibility.

They enhance the value of ISO 27001 certification by validating an organisation’s commitment to maintaining high security standards.

Choosing UKAS accreditation can mean that your certification is respected and valued in both domestic and international markets. By choosing a UKAS-accredited certification provider like British Assessment Bureau, your certification outweighs self-certified or non-accredited certificates because it demonstrates that your ISMS is checked, verified, and held to the highest standard by an independent third party.#
