ISO 27001 Consultancy
Build trust. Win business. Stay compliant.
Why ISO 27001 Matters
ISO 27001 is the international gold standard for Information Security Management Systems (ISMS). Achieving certification not only protects your organisation from cyber risks but also unlocks new business opportunities by demonstrating trust to clients, regulators, and partners.
At Thurnleigh Group, we make the certification journey straightforward. Our consultants combine deep technical knowledge with practical business insight, ensuring your ISMS is both compliant and efficient.
ISMS Scoping & Gap Analysis
We assess your current security posture against ISO 27001 requirements, identify gaps, and build a tailored roadmap for certification.
Consultancy & Implementation
We design and implement the policies, controls, and procedures that underpin a robust ISMS, aligning them with your business goals.
Audit Readiness & Representation
We prepare your organisation for certification audits with mock assessments, documentation reviews, and auditor engagement support, ensuring a smooth, first-time pass.
ISO 27001 doesn’t stop at certification. We provide ongoing monitoring, internal audit support, and improvement cycles to keep you compliant and resilient.
