Web browser security startup SquareX has closed a $20 million Series A funding round led by SYN Ventures.
SquareX offers what it has dubbed a “Browser Detection and Response (BDR)” solution that converts any web browser into an enterprise-grade secure browser, providing the same functionality as dedicated enterprise browsers without cumbersome change management.
The company claims that its browser extension effectively manages threats like malicious extensions, phishing, genAI data leakage, insider threats, and more, directly within the browser environment, reducing the enterprise attack surface without compromising user experience.
“The browser is the new endpoint, yet it remains a major blind spot for most organizations. Existing solutions often force a trade-off between security and usability,” said Vivek Ramachandran, CEO of SquareX. “We built SquareX to eliminate this compromise in browser security, offering robust protection that works with the browsers users are already familiar with.”
Existing investor Peak XV Partners (formerly Sequoia Capital SEA) also participated in the funding round.
