Cybersecurity Designed for the Connected Car Age

Upstream Security was founded by Yoav Levy (CEO) and Yonatan Appel (CTO), two seasoned security professionals with over 20 years of professional experience. They understood that the automotive market is undergoing a massive disruption, potentially greater than the one experienced by the  mobile phone industry and that this disruption will require radically different security solutions in order to reach its potential – automotive cybersecurity solutions purpose-built for the automotive industry and its unique challenges.


The automotive industry is undergoing a transformation – decades old business models are rapidly changing and connectivity is quickly becoming an integral part of conducting business. Connected cars sit at the core of a new smart mobility ecosystem. Connectivity enables automotive vendors and service providers to monetize car data and achieve superior operational results. Consumer experience as well as operational efficiency can be improved and new business opportunities can be imagined. At the same time, however, connectivity exposes vehicles to a wide array of risks that never existed before – cyber-threats as well as misuse.


OEM car makers and service providers alike have been challenged to date with identifying and locating cyber threats targeting their smart mobility services and connected vehicles. In order to secure the smart mobility ecosystem – vehicles, infrastructure and services – from attack, fraud or misuse, a new breed of security solutions is required, one that is purpose built for the unique challenges of the automotive industry and to the specific attributes of an individual connected car.


In a similar fashion to the transformation undergone by cybersecurity solutions in enterprise IT, automotive security solutions need to be designed for the age of “connected cars everywhere” and move from an endpoint (in-vehicle agent based) security model to a centralized cloud-based agent-less one. Cyber solutions must be able to understand and distill the massive amounts of unique data created by fleets.


Upstream helps corporations mitigate connectivity risks and ensure the safety and security of smart mobility solutions protecting connected and autonomous vehicles, SAE levels 0-5, on the roads today or twenty years from now, from remote cyber attacks generated over the public internet or private mobile APN as well as from fleet-wide attacks targeting multiple vehicles at the same time. We are a team of cybersecurity and data professionals with a clear focus on our customers’ success – the result is the most comprehensive protection of the mobility service infrastructure, connected vehicles and more importantly the people inside them.




Yoav is leading Upstream's strategic direction, culture and business execution, with over 17 years of experience in multi-national high-tech companies and start-ups. He brings rich leadership experience in management, marketing and business development of IT and security products spanning over a dozen years of experience in category leading vendors such as Check Point, Juniper Networks and Broadcom. Yoav is an avid kite boarder and surfer.



Yonatan is leading Upstream's cybersecurity research, bringing over 20 years of technology development and product management experience in industry-leading multinational companies. He brings deep experience in cybersecurity innovation in world-leading application security companies such as Check Point and Imperva and experience in developing enterprise-grade cloud-based analytics technologies in Microsoft. He also served in an elite technological unit in the IDF Intelligence Corps. Yonatan holds a BA in Computer Science from the Open University of Israel (cum laude) and an LLB from Tel Aviv University.
