About us

We are nation-state grade cyber defense and strategy experts. Our mission is to enable organizations in their cyber defense challenge, providing them with state-of-the art consulting, services, and solutions to help them proactively and holistically defend themselves in a new era of constantly evolving cyber threats — in both volume and level of sophistication.

Attackers, often backed by nation-states, use tools developed by the National Security Agency and other top worldwide defense agencies, that have now leaked to the Darknet.

Our holistic approach includes a comprehensive understanding of your business processes and critical and strategic assets including human resources, physical security, and supply chain vendors. We assess and handle threats from the viewpoint of highly sophisticated hackers and attackers to ensure fully defend your organization from top to bottom.

HolistiCyber brings years of experience in both the public and private sectors. Our world class experts are cybersecurity veterans of the Intelligence branch of the Israel Defense Forces (IDF). They have served at the front line of critical nation-state cybersecurity operations, both offensive and defensive. Therefore, our team’s expert analysts perform sophisticated, advanced nation-state level cybersecurity testing and assessments, working with your busy IT staff.

Let us put our experience to work for your organization!
