About Mark Su

Owner & CEO, IT Assure

Mark Su leads IT Assure with a business owner’s perspective on cybersecurity: protecting confidential information, preserving client trust, and making sure important responsibilities have a clear owner.

His background in finance and accounting shapes how he approaches technology. He looks for sound decisions, defined responsibilities, and processes that can be checked—especially where a firm’s reputation and its clients’ information are involved.

How Mark approaches cybersecurity

Professional firm leaders should be able to understand what protects their business, who is responsible, and what still needs attention.

That thinking informs IT Assure’s approach to managed cybersecurity: manage essential protections, repeatedly verify that they are working, and correct covered gaps. When an issue requires a business decision, leadership needs a clear explanation of the concern and the available next steps.

Technology plays an essential role. So do the everyday decisions surrounding it: who can access client files, how responsibilities are assigned, and whether identified issues are followed through to resolution.
