Cyber Security Certification and Accreditation
Helping organisations achieve Cyber Essentials, Cyber Essentials Plus, and ISO 27001 whilst strengthening security and governance.
Certification that means something
Cyber Essentials, Cyber Essentials Plus, and ISO 27001 are among the most widely recognised cyber security certifications in the UK. Achieving them demonstrates to clients, insurers, regulators, and other stakeholders that an organisation takes cyber security seriously. However, the value of certification depends entirely on why it is being pursued.
Organisations that treat accreditation as a box to tick in order to win a contract typically find themselves back at the start when it comes to renewal, because the underlying security has not changed.
Organisations that approach it as a genuine commitment to improving their security posture find that the process itself makes them more resilient, better prepared, and more confident in conversations with the people who rely on them.
We work exclusively with the second type of organisation.
Choosing the right certification
Different certifications suit different organisations depending on their size, sector, client requirements, regulatory obligations, and level of cyber security maturity.
Whether you are seeking a recognised baseline of cyber security controls through Cyber Essentials, independent technical assurance through Cyber Essentials Plus, or a comprehensive Information Security Management System through ISO 27001, we can help you determine the most appropriate route and guide you through the process.
Cyber Essentials and Cyber Essentials Plus
Cyber Essentials is a UK Government-backed cyber security certification scheme designed to help organisations implement a baseline level of protection against the most common cyber threats.
Cyber Essentials Plus builds on this foundation by introducing independent technical verification of the controls that have been implemented, providing greater assurance to clients, insurers, and other stakeholders.
For many organisations, Cyber Essentials provides an excellent starting point for improving cyber security while demonstrating a commitment to protecting business and client information.
Typical support includes:
- Gap assessments against Cyber Essentials requirements
- Remediation planning and prioritisation
- Microsoft 365 and endpoint security reviews
- Policy and documentation development
- Certification preparation and assessment support
- Support through annual renewals and ongoing compliance
ISO 27001
ISO 27001 is the internationally recognised standard for Information Security Management Systems (ISMS). Unlike Cyber Essentials, which focuses primarily on baseline technical controls, ISO 27001 establishes a comprehensive framework for managing information security risks across people, processes, and technology.
Whether the objective is to meet client requirements, strengthen governance, improve operational resilience, support growth, or win new business opportunities, ISO 27001 provides a structured and sustainable approach to information security management.
Our ISO 27001 engagements typically follow three structured phases:
Gap Analysis
- Assessment against ISO 27001 requirements
- Identification of gaps, risks, and improvement opportunities
- Development of a practical roadmap towards certification
- Recommendations on certification scope and implementation priorities
Implementation
- Design and implementation of the Information Security Management System (ISMS)
- Risk assessment and control selection
- Policy and documentation development
- Support for process and control implementation
- Facilitation of internal audits (or coordination with audit teams) and selection of an external audit body
Certification
- Preparation for Stage 1 and Stage 2 certification audits
- Stakeholder coaching and audit support
- Coordination with the chosen certification body
- Management of audit findings and corrective actions
Why Sibrossa?
Our experience extends beyond certification itself. We help organisations develop the governance, controls, and operational disciplines required to achieve meaningful and sustainable security improvements.
We have supported organisations across the professional services, transport and not-for-profit sectors with cyber security improvement programmes, governance frameworks, Cyber Essentials certification, and ISO 27001 implementation. Our experience includes providing Fractional CIO and CISO services, undertaking independent IT and cyber security reviews, and helping organisations align technology, security, and business objectives.
We also maintain Cyber Essentials and Cyber Essentials Plus certification ourselves, reflecting our commitment to applying the same standards and practices that we recommend to our clients.
We provide independent and pragmatic advice, helping organisations implement controls and governance arrangements that are proportionate to their size, complexity, and risk profile. Our focus is always on delivering practical improvements that strengthen security, support operational resilience, and provide lasting business value.
For many organisations, certification is not only about improving security; it is also about building trust, meeting client expectations, supporting regulatory requirements, and enabling future growth. We help organisations achieve these outcomes while ensuring certification remains the result of good security practices rather than the objective itself.
