January 24, 2017 | Israeli cyber security company Cybellum has raised $2.5 million in a seed financing round led by Blumberg Capital. The company will use the funding to fuel its expansion, including opening a US office in 2017, and to further its R&D efforts. Founded in 2015 by CEO Slava Bronfman and Michael Engstler, both veterans of the intelligence corps of the Israel Defence Forces (IDF), Tel Aviv-based Cybellum’s mission is to create a real and direct solution to cyber problems, specifically zero-day attacks. Zero-day attacks are cyber attacks against software flaws that are unknown and unpatched. The company also announced the discovery of three new zero-day vulnerabilities that are currently unpublished, unpatched and are potentially being used in the wild.
