How Licensefortress Started

LicenseFortress was created in 2014 by VLSS’s founder and chief architect, Dean Bolton, to help companies and organizations take control of their investments while removing the threat of non-compliance. VLSS spent nearly two decades specializing in Oracle and VMware technologies. VMware saw that many of their customers were subject to Oracle’s aggressive auditing tactics, especially in cloud environments, and approached VLSS about finding a solution for software asset management. Today LicenseFortress can proudly point to 90% customer satisfaction and customer retention rates among clients that range from Fortune 100 companies to government agencies and small-to-mid-sized businesses. LicenseFortress is the only software asset management managed service that provides a bundled offering including legal and technical advice under a financial guarantee. 


At LicenseFortress, we are fully committed to our customers, and we always strive to deliver innovative solutions on time and under budget for your software asset management needs. Our goal is to optimize your software investment by enhancing your understanding of software licensing and pricing practices. 

We help customers implement compliant software asset management strategies worldwide.
