Xerillion Corporation - Computer support and services in Palatine - 440 W Colfax St, USA

We are a new client (less than 6 months) but have been very satisfied with our relationship thus far. Xerillion is a Microsoft Cloud Solution Provider Partner and is committed to implementing what Microsoft envisions for the future. I really appreciate how the management has fully embraced Microsoft's recommendations to take advantage of all the Microsoft 365 Enterprise platform has to offer. So far, so good!

Unbelievable experience with Xerillion. They moved my company's entire IT infrastructure (server, phones, firewalls) off our old outdated physical server to the Microsoft Cloud. Our monthly IT costs were cut more than 60% and we have experienced no downtime. With the COVID-19 pandemic my company of 50 plus employees were able to seamlessly pick up and work from home or remote locations without any problems. Xerillion's staff is super responsive to emails or phone call when you need help. As business owner I cannot recommend Xerillion enough, A+++

We've been a client of Xerillion for two years. We utilize their help desk services and I can't say enough great things about their IT Technicians. They quickly became very familiar with our systems and our employees' needs. They are extremely responsive and I like that a live person answers all phone calls to triage our needs instead of an auto attendant. Our headcount has increased dramatically in the last two years and they hired additional IT Technicians to meet our growing needs. I've only received compliments from our employees about the services Xerillion provides.

We've been working with Xerillion as our managed service provider for over 2 years. With little interruption to our business they updated our IT infrastructure which improved our operations and in turn saved us money. They provide speedy, daily support for our company in a friendly and courteous manner. Their team of technicians, managers and office staff are knowledgeable, professional AND fun to work with. It's been a great experience.

Xerillion does a great job of managing our IT systems at our office. They help us stay up to date in this environment where technology and the ways we do things is changing so rapidly. They always help us do it in a way that is cost effective and help us to weigh the benefits vs. the cost. We have been with them many years and I have never had a reason to look anywhere else.

We have been a client of Xerillion for almost ten years. We are a small company with only a few employees and about 15 computers/devices. Our IT needs are relatively simple, but not trivial. Our size is awkward forcing us to (1) make-do with Geek Squad type outfits or (2) pay big bucks for a firm which doesn't understand how to service a small company on a budget. To my knowledge Xerillion is one of only a few firms which fills this niche, and they do it well. Like all companies, staff come and go. In 10 years with Xerillion we have always enjoyed working with great professionals.

Xerillion has been Vaxcel’s IT partner for nearly 7 years, and they have always met or exceeded our expectations. Before teaming up with Xerillion, we had a cobbled-together system with multiple servers, and Xerillion was able to propose commonsense solutions and a long-term plan for upgrading our infrastructure. We now have just 2 physical servers, and a managed fleet of up-to-date workstations. We had no formal data backup protocol, and Xerillion helped us select and implement a system with real time onsite and cloud data backup. When it was time to upgrade our email functionality, Xerillion helped us implement Microsoft O365, and then recently upgrade to Office 2016. On the rare occasions when something goes wrong, we know Xerillion is just an email or phone call away, and response is going to be nearly immediate. Most importantly, Xerillion has become a part of our fabric. The people are terrific, and we know they have our best interests at heart. A great company to work with!

I have been a customer of Xerillion for many years, which is a result of their exemplary service. They are equally as quick to respond to minor issues as serious network problems. The technicians are very knowledgeable and attentive to our needs, large or small. I have learned over the years that a primary goal of Xerillion is too keep me happy, which is accomplished by strong communication and quick efficient problem resolution.
