Tony Varriano
Director of Corporate Development
As an experienced executive, I specialize in providing effective strategy and guidance to shareholders, executives, and senior management. My focus is on leveraging modern Information Technology to support corporate goals and reduce risk while empowering teams.
As Director & CTO, I'm skilled in leveraging modern IT solutions to help organizations achieve their goals. I'm also a cybersecurity risk reduction expert, dedicated to ensuring that organizations are well-protected from digital threats. I help companies develop policies, processes, governance, and compliance frameworks that align with their strategic goals.
In addition, as a Modern IT Advocate, I drive the adoption of modern technology and best practices within the IT department to align with business goals. My responsibilities include educating and promoting the use of new technologies such as cloud computing, automation, and AI to improve efficiency, productivity, and security. I work closely with other departments such as finance and operations to understand their needs and ensure technology solutions align with the overall goals of the organization.
With a strong focus on Zero Trust security, I help organizations implement this approach to cybersecurity. I stay up to date with the latest trends and best practices in the field, as a senior member of the Microsoft Tech community and a Research panel member.
Whether you're looking to optimize your IT infrastructure, reduce risk, or develop effective cybersecurity measures, I'm here to help.
