Mario DiNatale

Chief Information Security Officer

Cybersecurity executive.

Over 2 decades Leading and Strengthening Enterprise Security Programs.

A CISO who allocates security like capital and speaks risk in the language of the business: every dollar an asymmetric bet, placed where it costs the adversary most. Priced in outcomes, not activity.

    I am uniquely qualified in my ability to identify the best and brightest minds in cyber security, of which I can definitively say that Mario is one.
  • JH
    Jeanette Horan
    Retired Chief Information Officer, IBM · Public Company Board Director
    He clearly has a deep passion for security topics and has helped his peers to be much more informed on risks. I find him to be very bright and engaging.
  • RM
    Richard Moore
    Former CISO, New York Life · Cyber Executive
    I have first-hand knowledge of Mario's ability to solve cybersecurity problems and identify solutions that would have eluded others.
  • MF
    Marc A. Feigen
    CEO, Feigen Advisors
    I am impressed with his cutting-edge knowledge of cyber-security, his ability to translate hard technical concepts into plain English, and his insistence on very high standards.
  • SC
    Sean M. Cross
    CEO & Managing Partner, Silicon Alley Advisers
    [On a hedge-fund penetration test:] the client suggested the work was reflective of that of a nation state. On all occasions, Mario's work has exceeded expectations.
  • FBI
    SSA Martin McBride
    Supervisory Special Agent, Federal Bureau of Investigation
    We see businesses with much bigger budgets unable to handle incidents as quickly and technically as Mario. Based on my 15+ years working cyber crime, Mario is better than any security professional working for any public or private entity in Connecticut.

Legend has it that Mario, born to blue-collar immigrant parents in a suburb of New Haven, Connecticut, came into this world with a screwdriver in his hand and began voiding warranties immediately thereafter. Rather than join the family construction business, he pursued a degree in Computer Science, much to his parents' chagrin. On the day he left for college, his father told him he wasn't sure there was "any money in computers," handed him a shovel, and said that if the whole computer thing didn't pan out, it would still be there waiting for him.

Mario went on to earn a reputation as one of the tech industry's top thought leaders, renowned for his visionary ideas and his expertise in cyber security. He rose to prominence as a respected business executive, recognized for his risk-focused strategies, transformative leadership, and a talent for inspiring security team cultures. That distinct approach has earned him the respect of his peers and the admiration of the teams he leads.

Even in an executive seat, he stays hands-on as a trusted cyber security adviser to governments, Fortune 50 CEOs, and federal law enforcement and intelligence agencies.

He fills his free time building Lego sets with his daughters, practicing Brazilian jiu-jitsu, and studying astronomy. And he still keeps the shovel his father gave him all those years ago.
