SquareX raises USD $20M to boost enterprise browser security

SquareX has secured USD $20 million in Series A funding for its browser security solution.

The investment round was led by SYN Ventures, a venture capital firm specialising in cybersecurity, with participation from existing investor Peak XV Partners, previously known as Sequoia Capital SEA.

SquareX provides a Browser Detection and Response (BDR) technology that allows any browser to be transformed into an enterprise-level secure browser through a simple extension. The company claims this approach enables organisations to manage threats such as malicious browser extensions, phishing attempts, generative AI data leakage, and insider threats directly within the browser environment.

Traditional enterprise security solutions often lack visibility into threats that target browsers. Some proprietary secure browsers can also disrupt user productivity due to required changes in workflow. SquareX's BDR extension is intended to bridge this gap by delivering enterprise-grade security without imposing additional steps or friction for end users.

"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. We built SquareX to eliminate this compromise in browser security, offering robust protection that works with the browsers users are already familiar with. This Series A funding, led by the team at SYN Ventures, validates our vision of everyone being able to be online without fear," Vivek Ramachandran, Chief Executive Officer of SquareX, said.

"SquareX is tackling one of the most significant and underserved areas in cybersecurity today. The browser is ground zero for countless attacks, and the team at SquareX has developed an elegant and powerful solution that provides critical visibility and control where it's needed most – directly within the native browser experience." Jay Leek, Managing Partner and Founder of SYN Ventures, commented.

"Having partnered with SquareX since their seed stage, we've been impressed by their vision and execution in tackling browser security challenges. We are excited to partner with them again as they demonstrate strong results in delivering much-needed cybersecurity capabilities to enterprise customers," Shailendra Singh, Managing Director at Peak XV, said.

According to SquareX, the Series A funding will enable the company to develop its BDR solution further and expand its reach among enterprises facing an evolving cybersecurity landscape. The company asserts that its browser extension is designed to secure organisations from a range of browser-based threats, including those posed by ransomware, spearphishing, and browser-native attacks.

SquareX is a team of seasoned cybersecurity professionals, visionary technologists, and passionate problem-solvers, all united by a shared goal: to empower internet users with cutting-edge solutions that protect their digital lives. 

Moreover, SquareX was founded by Vivek Ramachandran, a veteran in the cybersecurity industry with over 20 years of experience in building security products and identifying vulnerabilities in security systems. His entrepreneurial journey spans more than a decade, during which he has developed wireless monitoring solutions, penetration testing gadgets, and cloud-powered lab environments.
