We feel quite justifiably proud of all out glowing testimonials, which we think speak volumes about our commitment to client satisfaction

Jake has exceeded expectations from start to finish. He took the time to explain everything in plain English, always followed up after every call, and delivered an IT setup we have a lot of faith in. I can’t think of a way he could have been more helpful.

Property Investment Firm

In over 20+ years working in the professional IT industry, I have never experienced such a high level of dedication and service from an MSP nor company. Intersys excel on all areas of the business that other companies are unable to match or provide, supporting my firms every need with outstanding attention to detail, exceptional customer service, efficient and unmatched communication. From when a ticket is raised to the moment it is closed, I do not have to worry about the outcome as I know my company is in the best hands possible from the service that is provided. Since working and strengthening our relationship with Intersys they have delivered on their promise and go beyond to ensure my companies IT security and services are safe, secure and looked after.

I look forward to working with Intersys in the future, and could not think of any other provider that I would completely hold confidence in to trust with our companies IT security and support services

Our boutique firm needed technical experts who could independently audit our cyber security capabilities.

In November 2018 Catherine partnered with us to provide subject matter expertise for an internal audit of our Business Continuity Management framework.

Catherine is extremely organised, professional and pragmatic and gave us well-informed opinions that helped shape our planning and deliver a clear view of our current framework, as well as practical suggestions for improvements and a clear roadmap to implement these.
