What SquareX does
SquareX is a Singapore-incorporated cybersecurity company (SquareX Pte. Ltd.) that pioneered the Browser Detection and Response (BDR) category, providing a lightweight browser extension that detects, mitigates, and threat-hunts client-side web attacks in real time across Chrome, Edge, Firefox, and Safari. The platform operates at the browser layer—where most enterprise work and most modern attacks occur—addressing gaps left by Secure Web Gateways, EDR/XDR, and SSE platforms. Core capabilities include malicious browser extension detection, identity-attack and session-hijack prevention, browser-native data-loss prevention (covering GenAI, file, and clipboard vectors), disposable browser and file viewer isolation, and an enterprise browser mode that enables secure access to internal web apps, SSH, and RDP as a VDI/VPN replacement for BYOD and unmanaged devices. The technical foundation is supported by ongoing original research on attack techniques such as Browser Syncjacking, polymorphic extensions, browser-native ransomware, and AI browser vulnerabilities, alongside a patent filing credited to a principal engineer.
SquareX monetizes through a subscription model with a freemium Chrome Web Store extension for individual consumers and a quote-based enterprise tier for organizational deployments. The go-to-market blends product-led growth (self-serve browser extension install), an enterprise field sales motion targeting complex security buyers with BYOD needs, and a channel partnership with Wipro Ventures for managed security delivery. Marketing is anchored on thought leadership: research disclosures at Black Hat, DEF CON, and RSA, a podcast (Be Fearless), webinars, and earned coverage in Forbes, TechCrunch, BleepingComputer, and Dark Reading. The company reports $10.1M in 2025 revenue with a 69-person team; total disclosed funding is $26M across a $6M seed (Sequoia Capital Southeast Asia, May 2023) and a $20M Series A (SYN Ventures lead with Peak XV Partners and Wipro Ventures, April 2025). On February 5, 2026, Zscaler acquired SquareX to integrate BDR into its Zero Trust Exchange platform, effectively ending SquareX's independent trajectory.

SquareX product offering
Product offeringCore offering
SquareX provides a Browser Detection and Response (BDR) platform delivered as a lightweight browser extension compatible with Chrome, Edge, Firefox, and Safari. The platform detects and mitigates client-side web attacks including malicious extensions, identity attacks, browser-native ransomware, and data leakage through GenAI tools, while also enabling secure access to internal applications as a VDI and VPN replacement. The company offers a free consumer tier for individual users and an enterprise subscription tier for organizational deployments with advanced DLP, BYOD security, and threat hunting capabilities.
Product overview
SquareX pioneered the industry-first Browser Detection and Response (BDR) solution, a unified platform that transforms any browser into an enterprise-grade secure browser through a lightweight browser extension. The core BDR platform provides real-time detection and mitigation of client-side web attacks including malicious extensions, identity attacks, malware, and data leakage. The product portfolio includes Browser DLP modules (covering GenAI data loss, file DLP, and clipboard DLP) and Enterprise Browser capabilities for secure private access to internal apps, BYOD/unmanaged devices, and VDI replacement — all delivered through the same extension without requiring separate enterprise browsers. SquareX also conducts ongoing security research including Browser Syncjacking, polymorphic extensions, browser-native ransomware, and AI browser vulnerabilities. SquareX was acquired by Zscaler in February 2026.

SquareX competitors and assessment
Company assessmentBroad incumbents
- Proofpoint: Proofpoint is a leader in email and browser threat protection for enterprises, with overlapping capabilities around user-targeted attacks, identity, and data leakage — adjacent to SquareX's identity-attack and Browser DLP capabilities.
- Netskope: Netskope is a leading SSE/SASE platform with cloud-native web security and CASB capabilities that increasingly address browser-layer threats. It represents the incumbent stack against which SquareX's browser-extension architecture competes.
- Zscaler: Now SquareX's parent company, Zscaler operates the Zero Trust Exchange SSE/SASE platform. It is both an acquirer and a broader incumbent in web and zero-trust security, with overlapping capability areas in browser policy and threat prevention.
- Cisco: Cisco's Umbrella and broader security portfolio provide secure web gateway and DNS-layer security for enterprises. It represents a large incumbent whose stack competes with SquareX for browser and web threat prevention budgets.
- Palo Alto Networks: Palo Alto Networks offers Prisma Access (SSE/SASE) and the acquired Talon enterprise browser, providing a broad portfolio of overlapping capabilities with SquareX across web security, DLP, and enterprise browser.
Emerging players
- Perception Point: Perception Point focuses on advanced threat prevention across email, browsers, and collaboration apps, offering an emerging alternative to SquareX's BDR for organizations seeking browser-native threat detection within a managed-service model.
Direct peers
- Menlo Security: Menlo Security provides browser isolation and web security solutions that, like SquareX, focus on protecting users from browser-native threats including malicious websites and files. It is a direct competitor in browser-layer threat prevention for enterprises.
- Island: Island is the leading standalone enterprise browser, competing with SquareX's Enterprise Browser / VDI-replacement capabilities for secure access to internal web apps and BYOD protection. Both companies target the same browser-as-control-point opportunity.
- Seraphic Security: Seraphic Security delivers browser security via an extension-based approach (similar to SquareX) that protects any browser from web threats without requiring a dedicated enterprise browser. It competes head-to-head on the BDR-style architecture.
- Talon Cyber Security (Palo Alto Networks): Talon built an enterprise browser that was acquired by Palo Alto Networks, making Prisma Access Browser a direct competitor to SquareX's Enterprise Browser and BDR capabilities within larger SSE suites.
