I have known Sereno (and their previous business) since 2016 as they are the IT solutions providers of our private credit fund with complex operations. Sereno are exceptional in solving issues in a prompt manner. Most recently I have dealt with Sahaj who set me up on the company IT infrastructure within few hours which can take days in a similar business with the complexity that the fund has. Furthermore, Sahaj resolved more issues for me with 2fa, mobile and security set-ups. Team members are available as soon as an issue pops up and generally relationship is managed by a single person making things streamlined with the single person with all knowledge of issues and set-ups to date. I would highly recommend Sereno based on my personal experience of them solving multiple problems for me at the credit fund.

My company moved to Sereno IT over the new year and we have found the process not only to be painless but i would describe it as enjoyable. They have kept me and my team updated and in the process managed to save us money by developing our systems and removing unnecessary expenses on services that were no longer required. Great to find a partner that proactively works in the background with the best interests of my company at the forefront of their work.

We have been clients of Sereno IT's since summer 2023 and we have been extremely happy with the service we have received to date. Sereno have built their business with a direct aim to fix the issues that are notoriously problematic with MSPs, and having experienced some of these problems with our previous MSP, Sereno are truly achieving in their efforts.

Everything is so streamlined and easy for clients to use - their partner portal has truly thought of everything, from ordering IT equipment, to scheduling calls with engineers. The team always make sure everything is very clearly explained, and when things are a little more technical/ difficult to put into an email, we have received personal video explanations which have been so useful.

Highly recommend Sereno's services!

These guys are new in the market, but they provide outstanding service service. What is important to our company, that they comprehend hierarchy of team and therefore importance despite the issue is applied. When we need something urgent, they find a manpower to resolve it asap. And most important for me as an assistant, i don't have to have IT language to explain the issue, they know issue is there and they find it and fix it - i do not have to answer 10 questions if i have done this or that, but they fix it by jumping on the system, with in short time all is done and you can move on with your day. And they are always positive 🙂

We have been a customer of Sereno since Summer 2023 and the experience since has been overwhelmingly positive. We are an SMB working in a complex, safety-critical industry, where stable and reliable IT services are paramount. Sereno have never let us down, with their team of highly competent, customer-focused technicians, who always go the extra mile.

As well as high quality services, they are also proactive in identifying areas for improvement and where they can add value. Compared to many other traditional IT suppliers, they are interested in establishing a true partnership, where the needs of both parties are taken into consideration.

I really can't recommended Sereno IT highly enough, as the other 5* reviews on here will also testify.

Great company, full of energy and very attentive to our needs. You really get a personalised service, with the technical ability of a much larger company.

My business has recently adopted Sereno IT Support as our ITSM partner over the last quarter. This has been a sensible move for us as we scale, and the moving parts will become more complex as we grow. I have experienced a few issues, but these have been quickly addressed. One particular, tricky item involving my work mobile was a challenge - but, “We got there in the end! Thank you Tamim - your support has been very helpful and much appreciated”

Excellent, speedy, friendly and very 'human' service. Intuitive and easy to use platform. I'm the type of person who normally puts off raising IT tickets but Sereno has actually changed that for me because it's so easy and straightforward, and everything gets actioned quickly.

I've had the pleasure of working with Sereno for several months now, they are honestly absolutely fantastic. The service really is better than I have experienced from other support organisations.

The team is incredibly easy to work with. Everyone I have interacted with is friendly, seems to listen and is generally responsive. They also have a high level of understanding of industry specific problems which helps a lot.

We've has issues in the past with really slow response times but this an area where Sereno does really well. We're usually able to get an answer to queries within minutes, and resolutions within hours at most.

We have also used them for advisory services on security and are really happy with the results. It's been a much more efficient process than the in house team we have previously.

Highly recommend!
