He has extensive proven experience in decision support systems (DSS) related to cyber security investment, and security & safety control systems. His consulting firm, G. Bina, provides security and cyber-security advisory services across the top tier of the Israel private sector, including its infrastructure and defense firms, as well as most sensitive government, military and intelligence agencies. It also works in India supporting one of its critical financial markets infrastructure institutions and other global institution. In his book "Guidelines for a National Cyber Strategy", (co-authored with Ofer Assaf), Siboni outlines five points for which decisions are critical for determining a national strategy. Starting with the state's responsibility to protect the private sector in relation to cyberspace security and privacy issues. The second point relates to the state responsibility, to enforce the use of technologies and practices in cyberspace defense in the civilian sector, which in many cases is part of its critical infrastructures. The third point is the extent to which the state is entitled to store information about the civilian sector's activities in cyberspace in order to defend it. The fourth point concerns the state's responsibility to build cyberspace capabilities and use them in a manner that will attain the state's interests. And, finally, the fifth point is the state's ability to secure the infrastructure that will allow the realization of a cyber strategy over time. In October 2018, Siboni published a book titled: "Regulation in Cyber Space" (co-authored with Ido Sivan)A comprehensive study on the regulation of the cyber space. The book reviews various regulation models in key western countries, evaluated regulatory strategies from parallel domains and builds a multi-layered regulatory model for cyber space. While the model addresses Israeli cyberspace, it provides applicable strategies for other countries as well. The suggested framework uses several regulatory tools and is based on self-regulation by government authorities as well as mandatory regulation for the private sector. Siboni's professional standing in the security community is reflected in his being responsible for the organization of DCOI – the INSS USA – Israel Cyber Security Summit for the past three years. DCOI 2016, held in Washington DC in May, was a concerted effort of the state of Israel and INSS that aimed at enhancing collaboration between the two countries in cybersecurity. The summit was supported by Israeli state agencies and major private companies from across the U.S. Keynote speakers at this year's event included: Admiral Michael S. Rogers – Director, NSA; Alejandro Mayorkas – Deputy Secretary, DHS; General David Petraeus – Former Director, CIA; Richard A. Clarke – Former White House National Coordinator for Security & Shawn Henry – Former Assistant Director of the FBI Cyber Division.
