There’s Lots of MSPs Out There… 
So Why Us?

It’s been a great model for us and for our loyal clients.

Frequently Asked Questions

As a managed IT support provider, what's included in your service and what might cost me extra?
Because we create bespoke managed IT support and service plans for every client, there's no one-size-fits-all answer to that question. However, things that will incur additional charges include 24/7 live support and deploying a team member to your site on a permanent or semi-permanent basis. Also, a security operations centre or managed security service is quite distinct from managed support (see 'What do I need to know about cyber security…' below). In any case, every SLA we create outlines in detail what is and isn't included and the fees are upfront and clear. We are always transparent and fair. See our managed IT support pricing page for more details.
How does your managed IT support provider price work exactly?
In most cases, our charges are calculated on a cost-per-user basis. This suits most clients because it usually means there is an affordable option whatever the size of their organisation. Find out more about our pricing for our fully managed IT service.
How do you protect sensitive data?
We use end-to-end encryption, multi-factor authentication (MFA) and zero-trust architecture to keep your sensitive information safe. Our advanced threat detection systems provide live monitoring, and our secure data segmentation and access controls make sure that only authorised personnel can access critical systems. Scheduled penetration testing and full vulnerability assessments further strengthen our security posture.
Do you understand the compliance landscape for highly regulated industries?
Yes, we work with clients in highly regulated industries such as financial services, pharmaceuticals, life sciences, and mining and exploration. For all of these clients, we address their compliance needs by undertaking a thorough risk assessment as part of onboarding. We help clients comply with GDPR, DORA, NIS2 and with bodies such as the MHRA and FCA.
Can we use you as our MSP alongside our own IT professionals?
Absolutely. Quite often, a client needs us to provide additional support and expertise to an existing team. We will ensure your team is fully onboard with any changes we make, and will train them in new systems or processes. Ultimately, we are team players and will work sensitively and sympathetically with your own people towards the greater good that is high-performing IT!
What do I need to know about cyber security and fully managed IT services?
Firstly, that you are in good hands. We are an IT and cyber security business – security hardening is a core skill and we are well-respected within our industry for our approach.

Intersys is ISO 27001:2022 certified, the international standard for information security management systems. We also follow the internationally recognised and leading NIST Cybersecurity Framework, with its emphasis on the core functions Identify, Protect, Detect, Respond and Recover. This means protocols will be in place for protecting your data, including regular antivirus updates and monitoring of potential threats.

However, we want to make something very clear: managed IT support and services are not the same thing as a managed security service such as CSaaS (cyber security as a service). These are dedicated cyber security services that go beyond the security provided by a managed IT support service. If you feel your organisation would benefit from this dedicated security approach, we can help. Get in touch with us below.
Didn’t I see Intersys quoted about IT and cyber security in the news?
Quite likely. We are regularly approached by journalists to provide insights into issues around cyber security and IT, including the emergence of AI tools. Our senior leaders have spoken to the Guardian, Commercial Risk and the Insurance Times about IT risk strategies. We’ve talked to Cybersecurity Magazine about cyber security in the insurance industry. Also, our growing presence in the London Market has been reported in industry publications.
