ROSH HAAYIN, Israel and Stamford, CT, December 2, 2020 Source Defense, the market leader in client-side website security, today announced the appointment of Sagi Shvartz as the company’s Vice President of Research and Development. In this role, Shvartz is responsible for leading the technical team to further innovate and advance the Source Defense platform to meet the growing security needs of customers and consumers. He will work closely alongside Chief Technology Officer and Co-founder Hadar Blutrich, who remains focused on long-term technology architecture, exploring inorganic growth opportunities and more.


Shvartz brings over 20 years of technical and operational experience leading Research and Development, Data, DevOps, IT and Cybersecurity teams, with a proven track record designing and building a wide range of online products. He is the former COO of financial markets platform, Investing.com and CTO of online website directory company Walla! News.

“There were two things that really attracted me to this position with Source Defense: the market opportunity and the people,” said Shvartz. “What Source Defense does is important in this time of digital and cultural transformation and growth. Being charged with helping the biggest and best companies in the world improve their website security, engaging with our customers’ needs and other elements of making the website more secure is a great honor. I’m equally excited about our team, the wealth of knowledge they bring to this space and the growth of the market.”

This appointment comes on the heels of tremendous company momentum that includes being named one of Forbes Top 20 Cybersecurity Companies to Watch in 2020 and successfully launching its “Website in Page Protection” (WiPP) solution that protects websites from attacks originating from first-party code, insider threats, and other vulnerabilities.
