Certified Mission Critical Operator & Professional

Advance your Career in Mission Critical Operations

What are the differences between CMCO and CMCP?
CMCO is geared toward operators and technicians within the data center industry who need to test their foundational “mission critical” knowledge.  Many of the individuals who obtain CMCO certification are highly encouraged to study and take the CMCP exam as well.
CMCP is a stand-alone certification that is geared toward “professionals” working within all 16 mission critical sectors, including emergency management, energy, financial services, health care, information technology, manufacturing, nuclear, water, wastewater management, data, and others.
*It’s important to note that neither CMCO nor CMCP are Information Technology certifications. In fact, they are specifically focused on protections and safety surrounding mission-critical infrastructures.*

Mission Critical Operators keep data center facilities, technology, and processes running and protected for organizations that require continuous data and software access for success. Using knowledge and skills in information technology (IT), operations technology (OT), and maintenance, Mission Critical Operators ensure that the complex and critical systems that support data centers are available 24 hours a day and 7 days a week.

Operating data centers that are hyperscale, edge, and everything in between requires a high level of skill and employers are constantly looking for the professionals who can do the job. How do potential employees know if they are ready for this work, and how do employers gain confidence that the candidates they seek are qualified? The CMCO program addresses these vital questions.

Why become certified in mission critical operations?

Imagine sitting down at your computer only to find that you have no access to your company’s critical data because your servers are off-line. Or you trying making a purchase online only to find that the system is down. These, and other similar incidents, could happen if mission critical data centers are not properly managed or maintained. For excellence in operating a Mission Critical data center, you can count on a Certified Mission Critical Operator (CMCO).


A mission critical operation is any operation requiring round-the-clock supervision of systems. Certified Mission Critical Professionals (CMCPs) work to keep facilities running and protected so that there is minimal downtime. CMCPs work to combat the evolving threat of critical infrastructure operations’ failures on a daily basis, and also work to restore systems and mitigate damage when mission critical systems fail.
