About Grant Bannister

I am passionate about the ever-evolving world of cybersecurity and the constant change of technologies. With employees working hybrid and organizations adopting the cloud the landscape of security is not what it was 5 years ago. I am particularly passionate about Zero Trust and have dedicated myself to understanding and sharing its benefits. I have successfully influenced organizations to adopt the methodology by clearly articulating the advantages and delivering the necessary changes. I believe that implementing a Zero Trust Model is an essential step towards building a robust and resilient modern cybersecurity strategy.I pride myself on both technical and non-technical skills. My written and verbal communication underpins my ability to engage with all levels within an organization, which in turn provides better collaboration and results with technical designs and implementations.My career goal is to work for an organization that values and encourages individuals to make meaningful contributions to the organization and industry. I am eager to take on new challenges and improve the cybersecurity posture through modern technologies and principles.
