‘We offer the high-level security and consultancy required by London organisations of all sizes'

I began Intersys more than 25 years ago, servicing the City. We specialise in cyber security, and also offer complete IT services in London to many sectors, from financial services and life sciences to SMEs and schools. London is home to some of the most heavily regulated industries in the UK, who are working at a high-level of complexity in terms of security, compliance and business continuity. My Aldgate-based team knows the territory and will ensure your IT infrastructure meets every requirement. We were – and are – very much a London IT company.

Common Questions Answered

How do I know your IT services in London are up there with the best?
When evaluating an IT company, search for ‘trust signals’. These indicators suggest or even prove a partner will undertake your project to industry best practice. On our website you’ll find many trust signals. We are Microsoft Gold-Certified, which means we work closely with Microsoft and meet the highest standards when introducing or troubleshooting Microsoft products. We hold ISO 27001 Information Security Management accreditation, which ensures a robust approach to information security. We also have a large database of client recommendations and case studies from organisations similar to yours, who came to Intersys and enjoyed successful outcomes.

Do your IT Services in London offer greater technical expertise than competitors?
We don’t know about every competitor, but we would say: there’s a very high probability. This is largely because we are an IT-led company, not a sales led one. This is an important difference because many IT business work on a sales-based model, which is largely about selling you stuff. We do NOT work on a sales-based model. Our MD, Matthew Geyman, is a self-declared tech geek and all of our leadership team come from technology backgrounds. Work with us and we will be figuring out how to solve your problems and find perfect-fit solutions – NOT what we can sell you. This is not always the case.
Should I search for more than technical skills when searching for IT services in London?
Definitely! As well as providing leading IT expertise, we offer something many London IT companies do not: attentive customer service. This is more than an ‘added bonus’. Good customer service implies the ability to listen and properly take a brief, so you get the right solution. It also suggests the regular support and aftercare you would expect from a company that values long-term relationships with its clients. At Intersys, this customer-first approach is also bound up with our ‘service not sales’ approach, with puts fairness and transparency above quick sales.
Do you offer 24/7 IT support?
Yes, on a client-by-client basis. Let's talk about your needs and we can propose a full-cover plan that will work for you.
