About RKON

Great People Driving Great Results

Since 1998, RKON has delivered IT Transformation helping private equity and enterprise firms achieve Quiet IT from vision to execution. We believe IT should seamlessly serve the business strategy versus getting in the way of execution. Headquartered in Chicago, IL our team has developed a refined approach, through years of experience, that delivers a clear vision of a scalable, agile, secure, cost optimized and low risk end state. To achieve this end state, we provide IT solutions in three stages, first building an advisory practice that sends the strategy in the right direction, an execution practice ensuring that vision is turned into reality and a management practice that keeps the vision on track as IT evolves to serve the business.

In 2024, we took great strides towards an aggressive growth strategy, fueled by the private equity investment from Post Capital Partners LLC. In the same year, we acquired Bridge Security Advisors, a leading specialist in cloud security, governance risk and compliance (GRC), and identity and access management solutions. The acquisition was part of our strategic push to broaden our cybersecurity capabilities and meet the increasing demand for comprehensive security solutions. The acquisition enhanced our capabilities in highly regulated sectors, including healthcare, finance, and manufacturing. We grew our footprint to support clients in these industries with additional resources and expertise to address complex cybersecurity challenges. Build your organization’s IT infrastructure with RKON and realize the unrestricted possibilities of Quiet IT.

We understand that our client’s success starts with our organizational cohesion. Recognized by Computerworld as one of the 100 Best Places to Work in IT, RKON is focused on developing an organization that fosters creativity, innovation and cooperation across all levels.

Jeff Mullarkey

“RKON started off as a consulting firm helping clients through complex IT change. Our primary focus was security, compliance, and infrastructure around mission-critical applications. We found that while most clients understand the basics, many struggle with complex infrastructure solutions. Hiring and retaining specialty skill sets while simultaneously keeping up with the evolution and maintenance of those solutions is difficult and costly, but with RKON’s advisors, companies quickly learned how to unlock these complexities.

20 years ago, our clients started asking us to take over IT solutions and management. Those same clients recognized that we could efficiently and effectively manage their IT, enabling them to focus on their primary business and create value. Happily, we found that once we managed the complex stuff, the rest was easy.”

– Jeff Mullarkey, CEO
