A Strategic Addition to an Integrated Certification Portfolio
TLI Group is a trusted provider of utility infrastructure services across Ireland, Northern Ireland, and the UK. Operating across Power Transmission & Distribution, Renewables & Engineering, Smart Energy Services, and Telecoms, the business delivers high-value solutions underpinned by technical expertise and strong governance.
Already certified to ISO 9001, ISO 14001, ISO 45001, and ISO 50001, TLI Group recognised that demonstrating a robust approach to information security was critical for clients and stakeholders – especially in a fast-evolving digital and regulatory environment. Achieving ISO 27001 was an important step towards enhancing efforts to improve operational resilience.
The Challenge
In today’s digital world, all organisations face a key challenge: the need for a more structured, organisation-wide approach to information security. Often in organisations, existing security measures, develop organically and lack consistency. This makes it difficult to evaluate overall risk exposure or align with client expectations – particularly those in highly regulated sectors.
For TLI Group, historically, information security responsibilities were largely centralised within the IT department. This siloed structure limited cross-functional understanding and left room for improvement in critical areas like access control, data handling, and incident response. A broader cultural shift was needed to embed information security across the business.
The Solution
TLI Group approached Amtivo (formerly Certification Europe) for ISO 27001 information security certification, based on a strong, existing partnership built through previous certifications.
For IT Manager Cillian O’Regan, this was the first time leading a certification project. Supported by Amtivo’s clear audit process and professional team, TLI Group began their journey to certification.
The Process
A number of critical elements contributed to a successful certification:
- Structured onboarding: Clear expectations and timelines provided strong initial direction.
- Guided implementation: Clear guidance during the audit process helped ensure the certification requirements were understood and addressed appropriately.
- Collaborative expertise: Amtivo’s auditors translated complex ISO requirements into tangible, actionable steps.
- Cross-departmental ownership: The project fostered a shared responsibility for information security across business units, not just IT.
Key Results
Following certification, TLI Group observed the following outcomes:
- Stronger security posture: A systematic approach to risk and controls now underpins TLI Group’s governance structure.
- Increased client confidence: ISO 27001 provides assurance to TLI’s clients that data protection and security meet global best practice.
- Enhanced credibility in the market: The new certification has enhanced market credibility and opened doors to new business growth.
- Operational consistency: Security responsibilities are now embedded throughout the business.
- Integrated improvement: With five ISO certifications, TLI Group has built a resilient, standards-driven platform for future progress.
The Experience with Amtivo
TLI Group describes their certification experience with Amtivo as “collaborative, empowering, and professionally guided”. The structured approach helped simplify a high-stakes process and provided the confidence needed to succeed.
