The increasing roles of chief information officers (CIOs) can encompass a company's complete infrastructure.

The CIO can ensure a company's relevance 10 or 20 years into the future.

But CEOs, CFOs and boards of directors are all making demands on CIOs: to increase agility, drive competitive advantage and optimize risk and costs throughout the enterprise.

Unfortunately, many CIOs are aware of only 50 percent of the SaaS/cloud solutions used in their enterprises. This leaves companies exposed to security risks and without a plan for managing it.

What People Are Saying About Mark

I found Mark Tonnesen’s information and advice very useful, and I’ll be using his recommendations in my practice. As the “requestor,” I quite liked the format, and thought that 30-minutes’ consult is actually a very workable model. It was sufficient time to discuss my targeted questions, exchange information, and receive recommendations. And of course it was the perfect amount of time to let me decide whether to engage the expert for additional questions.
