About Acumen

Acumen is a St. Louis IT and Cybersecurity company that helps businesses stay secure, supported, and easier to manage.

Since 1994, Acumen has worked with small and mid-sized organizations that need responsive local IT support, stronger security oversight, and practical guidance for business technology. We help clients reduce downtime, improve reliability, strengthen security, and make better technology decisions over time.

Our approach is built around proactive support, clear accountability, and steady improvement. Instead of waiting for problems to disrupt your business, we work to keep systems stable, users productive, and risks better managed.

What We Do

Acumen provides managed IT services, Cybersecurity services, IT project services, cloud services, backup management, infrastructure planning, security compliance, and ongoing technology support for St. Louis businesses.

Some organizations need a fully managed IT partner. Others need a local team that can strengthen security, support day-to-day operations, handle projects, and bring more structure to their technology environment. Acumen helps businesses choose the right support model based on their needs, risk profile, and internal resources.

Our services are designed to help businesses operate more reliably, recover more effectively, and move forward with practical, security-minded technology decisions.

Leadership

Acumen is led by Rob Wagnon, President & Owner, and Deborah Wagnon, Vice President & Owner.

Rob Wagnon founded Acumen in 1994. He has led the company through major shifts in business technology, from its software development roots to managed IT services, IT project services, and modern Cybersecurity support for businesses in the St. Louis area.

Deborah Wagnon has helped lead Acumen since 2004.  Deborah Wagnon earned her MBA from Washington University in St. Louis and brings that business perspective to Acumen’s leadership, operations, and long-term planning. Together, Rob and Deborah have built Acumen as a family-owned St. Louis technology company focused on long-term client relationships, practical service, and dependable business support.
