Colorado IT services provider covering managed IT, cyber security, web development and procurement

Denver-based Greystone Technology Group provides managed IT across Colorado, including Fort Collins and Boulder, and in the New York metro area. The company says it has provided outsourced IT, technical support and web development for more than twenty years. It presents its work as technology that runs smoothly for a client so that the client does not have to manage it.
The services include managed IT and day-to-day IT support, IT consulting, cyber security, web and app development, IT procurement and end-user training. Managed services and support keep a company's systems running, while consulting gives strategic guidance on how technology can support the business's direction. Procurement covers sourcing hardware and software and supporting the rollout. Training covers cyber security awareness and Microsoft Office 365.
The company's cyber security work starts with a risk assessment and a roadmap that it calls its Common Sense Cybersecurity Roadmap. The aim is to bring a clear, practical order to protecting an organization, rather than adding layers of complexity. Its web and app development team works mainly in WordPress and builds responsive sites with an emphasis on user experience.
Greystone says that most internal IT departments cover only part of what a business needs, and that most outsourced options cover even less. Its answer is a small team that works as part of the client's own staff, which gives it more context about the organization and so a deeper understanding of its problems. Requests are overseen by experienced staff from the start, which the firm says speeds up resolution. The company describes itself as a Colorado employer for IT roles, noting that it has been named a top workplace by a Denver newspaper five times and that it holds partner status with Microsoft, Dell and Cisco.
Its clients include firms in construction and development, the financial sector, government and non-profit bodies, healthcare, legal practices, manufacturing, oil and gas, professional services, restaurants, retail and start-ups. The firm presents its experience across these sectors as the reason it can tailor its support to each client's needs.
