Profile bio

About Mark O'Hare

I am a highly accomplished, results driven Chief Information Security Officer (CISO) and IT professional with over twenty-five years’ experience, the last eleven as the CISO for Mimecast, a $5.8 billion (USD) publicly traded global SaaS security company.I started my career in the technical and engineering disciplines of IT, but naturally gravitated to the management and executive tracks as I preferred developing strategy, monitoring and managing objectives, and nurturing talent in the organisation. As an Executive, and Director of Mimecast Australia, I have a proven track record of planning and implementing strategy, governance, and risk programs to support the vision, mission, and objectives of a hyper-growth organisation.During my tenure as CISO, I regularly reported to the Board of Directors on cybersecurity and risk strategy. I supported Mimecast’s transition from a private company to a publicly listed company on the NASDAQ, in 2015, and from a public company back to a private company after a private equity group acquired the organisation in 2022. I also supported Mimecast’s growth from fewer than 30 employees in 2008 to over 2000 in 2022.I strive to give my employees every opportunity to do their greatest learning and development along with their greatest work and teamwork. I believe it is a leader’s top priority to support their employees to reach their full potential. I thrive on building and being part of high-performance teams. I have excellent interpersonal skills and I am skilled at resolving conflict and enjoy making strong relationships across an organisation. I pride myself on analytical thinking, resourcefulness and bringing a collaborative mindset to the teams I work on and in. I strongly believe in lifelong learning and self-evaluation to improve one’s knowledge and abilities.I would add value to an organisation by bringing my passion, commitment, and pragmatism to developing, supporting, and monitoring the organisation’s strategic goals and objectives, especially in the high risk areas of cybersecurity and privacy.

Listed skills include Linux, Information Security Management, Information Security, Security, and 33 others.
