About Us

Pragmatic PKI solutions and training to secure your organization now and in the future

As we become ever-more dependent on online services and devices, the need to secure data, electronic transactions and vital information is more important — and challenging — than even before. Many of the online services we enjoy today are made possible through the use of a public key infrastructure (PKI). A well-designed PKI combines roles, policies, software and hardware elements to enable secure electronic transfer of information—far more securely than what’s possible with simple password authentication.

While PKI is effective and well-proven, designing and implementing a PKI can be complex, and when it comes to cybersecurity, even small missteps can be costly. That’s where we come in.

At PKI Solutions, we have deep knowledge and experience in all things PKI. Our PKI Microsoft Active Directory Certificate Services (ADCS) training courses are second to none. And we’re ready to help with whatever your organization needs, whether it’s general PKI design and implementation or using PKI to better secure IoT and mobile devices.

Our team is knowledgeable, pragmatic and responsive. When you think PKI, think PKI Solutions.

Mark B. Cooper
President & Founder

Mark B. Cooper is a former Microsoft senior engineer and leading world-wide subject matter expert for Microsoft Active Directory Certificate Services (ADCS). Known as “The PKI Guy” during his 10-year tenure at Microsoft, he traveled the world supporting and advising many of Microsoft’s Fortune 500 customers on all things related to PKI.


Taking this experience a step further, Mark left Microsoft in 2014 to form PKI Solutions Inc., which has allowed him to support a broader cross-section of organizations in the PKI space and to promote greater adoption of PKI technologies.

Among his accomplishments at Microsoft, Mark developed and managed the Microsoft PKI Health Check to analyze and report on the design and management of PKI components and created Microsoft’s first consolidated set of PKI best practices. He also found time to author several Microsoft whitepapers, including the specifications and deployment of ADCS on Microsoft Windows Failover Clusters.

Mark has been working with Microsoft technologies since 1992 when he achieved his first MCP certification with Microsoft exam #001. He has subsequently earned the MCSE accreditation for every Microsoft operating system since Windows NT 3.51, and is a Microsoft Certified Trainer (MCT), Microsoft Security MVP and Charter Microsoft Certified Master – Directory Services (MCM). In fact, if you have Microsoft MCM-Directory accreditation, Mark developed and most likely delivered the PKI portion of your training.
