Bad IT!

Bad IT is Going to cost you

A stagnating internal team, a poor-quality offshored service, or a partner focused only on selling you product WILL hold back your growth. These problems are all too common:
  • Overpromising and underdelivering.
  • Few high-level technicians.
  • No single point of contact.
  • Pitching at you – constantly.
  • Lack of cyber security expertise.
  • Too much outsourcing.

'We focus on serving our clients with diligence and integrity – and they keep coming back'

From the very beginning, I started the company because I was an IT nerd – not a salesman. It’s always been my view that if we focus on serving our clients with diligence and integrity, the rewards in our own business will come from doing the right thing. We are not an IT sales organisation. Every innovation or strategy we introduce is about powering our clients forward with great IT. This is complemented by fair and transparent pricing and a strong customer service ethos. It’s why clients keep coming back to us year after year.

Frequently Asked Questions

How do I know I can trust you with my IT?
Because we have the experience, integrity and recommendations to prove it. IT companies come and go very quickly, but Intersys has played a prominent role in the industry for over 25 years because we have a reputation for treating our clients’ IT with diligence and discretion. This is backed up by our accreditations to the highest industry standards – including ISO 27001 certification, an internationally recognised accreditation for information security. Finally, you can read testimonials from long-standing customers who come back to us again and again because they know that their IT is secure with Intersys. It’s the reason why we provide IT services for some of the most security- conscious sectors in the world, including life sciences and education.
We have our own in-house IT. How’s that going to work for you?
Our approach is very much about partnership. We can work with your own IT teams to provide either a holistic upgrading of your systems, or more targeted improvements. In either case, we will work closely with your people to ensure they are on board with the process and trained in any new processes or tools where necessary. Our team is made up of great communicators who will explain their rationale for any suggested changes and support your team all the way.
I’ve had bad experiences with IT businesses before – what makes you different?
Unfortunately, this is the reality in our industry. We have seen businesses choose very competitively priced IT providers – only to discover their ‘partner’ is more focused on selling them services than finding solutions. We like to make this point very clear: we are not an IT sales organisation. When our MD Matthew Geyman founded Intersys, he came from IT, not sales. We are IT people through and through and everything we do for you is through the prism of finding IT solutions. Please, do pick up the phone and give us a call. We’ll put you through to one of our experts and you’ll quickly realise you are talking to an IT person, not a salesperson. It’s this alone that has reassured many clients we have a very different ethos than far too many rivals.
