Overview

Implement the Right Controls for Your Risk Profile

ISO 27001 Annex A contains 93 controls across 4 themes — but not every control applies to every organisation. The Statement of Applicability determines which controls are required based on your risk assessment, and implementing them effectively is where many ISMS projects stall.

Our security controls implementation service takes your SoA and risk treatment plan and turns them into reality — selecting, configuring, and documenting each applicable control with the evidence required to demonstrate effectiveness to your certification auditor.

Statement of Applicability review and gap mapping
Access control — identity, privilege management, and authentication
Cryptographic controls — encryption policy and key management
Physical and environmental security controls
Operations security — malware, backup, logging, and monitoring
Supplier relationship security and third-party management

What We Deliver

Services tailored to your organisation

Access & Identity Controls

Implement robust identity and access management — privileged access, MFA, RBAC, and joiners/movers/leavers processes.

Covers Active Directory hardening, Entra ID Conditional Access, service account controls, and privileged access workstations.

Cryptographic Controls

Develop and implement encryption policies covering data at rest, data in transit, and cryptographic key management.

Includes full-disk encryption, database TDE, TLS configuration standards, and key vault implementation guidance.

Operations Security

Implement operational controls — anti-malware, patch management, backup procedures, logging, and vulnerability management.

Hands-on configuration support for EDR deployment, centralised logging (SIEM), and automated patch management workflows.

Monitoring & Audit Logging

Deploy security event logging, monitoring, and alerting to detect and investigate security incidents.

Includes log retention policy, SIEM alert rule development, and integration with your incident response procedures.

Key Benefits

Measurable outcomes that drive real value

Audit-Ready

Full Evidence Pack

Every implemented control is documented with objective evidence in the format your certification auditor expects.

Risk-Reduced

Material Security Improvement

Well-implemented Annex A controls deliver real reductions in your organisation's information security risk exposure.

Efficient

No Over-Engineering

Risk-based control selection means you implement what your risk profile requires — not every possible control regardless of relevance.

Why Choose Us

Our expertise and proven track record make us your ideal partner for iso 27001 security controls implementation

Comprehensive Audit-Ready Documentation

We generate meticulous evidence documentation for every Annex A control, ensuring your organization is fully prepared for internal and external audits. This precision minimizes certification delays and reduces the administrative burden on your internal teams.

Risk-Aligned Implementation Strategy

Our experts tailor the implementation of security controls to match your specific risk profile rather than applying a one-size-fits-all approach. This ensures that you receive maximum security coverage where it matters most while optimizing your operational budget.

Proven Technical and Governance Expertise

Our consultants bring deep technical proficiency in cryptography, access management, and secure operations to bridge the gap between policy and practice. We ensure your security framework is not just a document on a shelf, but a functional, protective system.

Streamlined Supplier Relationship Management

We implement standardized controls for supplier security, protecting your supply chain from third-party vulnerabilities. By securing these relationships, we minimize your exposure to vendor risk and improve your overall cybersecurity posture.

Frequently Asked Questions
