What our clients say


Sivantos Group

CISO Assurance Group boosted our privacy & security awareness as well as the underlying standards and processes onto a new level. They owned and actively drove the program from within the R&D organization, and helped us to enhance transparency, cross-functional governance and compliance during our journey towards GDPR. The consultant is very knowledgeable, structured and diligent, and always found the right balance between regulatory/legal requirements, customer and corporate interests, industry best practices, real-life scenarios and operational efficiency. It was a pleasure working with them, and I hope our paths will cross again in the future.

I had the privilege of working with CISO Assurance at our client South African Airways. The consultant was the Principle Security Officer during his time on the account. The consultant was heavily involved in identifying all potential security threats as well as developing the mitigation plans for each risk. The consultant communicates very well across all levels in an organisation and I believe is an asset to any company. I look forward to working together again in the future.

The CISO Assurance consultant has a pragmatic and realistic approach to Information Security. His knowledge of the current business challenges and the context of current industry thinking has been invaluable in determining the appropriate Information Security solutions to apply to programmes and projects I have managed at Oxfam. It has been great to work with him, always diligent and willing to help work through security concerns and opportunities. His sense of humor has also been invaluable in working through some of the stickier Information Security issues my projects have been faced with.

Cathal contracted for us as an Information Security Officer. He is very knowledgeable about Information Security, Compliance, Security policies and Governance. He is particularly excellent in User Education & Awareness and engaging with Stakeholders and Board members. He continuously develops himself by pursuing various Security certifications and keeps abreast of new security technologies and threats. As a former customer of Cathal, I highly recommend him and thank him for the good work he delivered by helping us achieve ISO 27001:2013 migration and maintaining PCI DSS compliance.

I have worked with Cathal at the JSE during the past year and have found him to be very professional at all times. He has made a good impression on the client and they have commended him on his ISO role that he performed at the JSE. I would highly recommend Cathal for any ISO position.
