Revolutionizing Browser Security
During his time at Pentester Academy, Vivek Ramachandran interacted with hundreds of security professionals and meticulously analyzed numerous adversary techniques. This research revealed a critical gap in modern enterprise security: the browser, despite being the primary application for most employees, remains alarmingly under-protected.
Employees now dedicate over 85% of their productive work hours to the browser, making it the primary gateway to company data and resources—making it the new endpoint. However, it being one of the least secured applications, leaves organizations with limited visibility into browser activity. Furthermore, most organizations lack the necessary tools to effectively measure or prevent web-based attacks. This vulnerability has transformed the browser into a prime attack vector, with employees—often the weakest link—becoming direct targets.
Traditional security solutions, such as SASE/SSE and Secure Web Gateways, fail to address client-side web threats effectively. Endpoint security tools, while valuable, lack the necessary visibility into browser activity to detect and mitigate threats effectively. This leaves organizations exposed to an ever-evolving threat landscape.
Recognizing this critical gap, Vivek Ramachandran founded SquareX with a vision to revolutionize browser security. SquareX introduces the industry’s first BDR (Browser Detection and Response) solution, designed to provide enterprises with comprehensive visibility into browser activity while simultaneously safeguarding against advanced threats.
Deployable within minutes as a browser extension, SquareX protects employees from a wide range of threats, including malicious QR codes, Browser-in-the-Browser phishing, macro-based malware, and other web attacks involving compromised files, websites, scripts, or networks. By operating directly within the browser, SquareX delivers unparalleled insight into the entire attack chain, empowering enterprises to proactively hunt for threats and identify similar attacks across their networks.
Unmasking the Hidden Dangers of Client-Side Attacks
Vivek Ramachandran has consistently warned about the escalating threat of client-side attacks, those insidious attacks that occur directly within the user’s browser. These attacks often evade traditional network-based defenses such as Secure Web Gateways (SWGs), leaving enterprises vulnerable.
Attackers are well aware of this loophole and have devised sophisticated techniques, such as Last Mile Reassembly Attacks, to deliver malware and exfiltrate sensitive data undetected by traditional security tools. Vivek Ramachandran and his team brought this critical vulnerability to the forefront during their impactful main stage talk at DEFCON 32.
Their research and presentation have significantly influenced the cybersecurity landscape, compelling SWG vendors to re-evaluate their cloud-based models for detecting client-side web attacks. Moreover, it has prompted enterprises to reassess their security strategies and prioritize robust protection against these emerging threats.
Another critical threat, often overlooked by many organizations, is the rise of malicious browser extensions. With the advancements in AI, attackers can easily create deceptive extensions that masquerade as legitimate productivity tools, such as the numerous fake ChatGPT extensions that have emerged recently.
The danger posed by these malicious extensions is significant. Vivek Ramachandran’s team has demonstrated that even with the enhanced security controls of Google’s new Manifest V3 (MV3) framework for browser extensions, attackers can still develop rogue extensions capable of stealing data and redirecting employees to phishing sites. This alarming reality underscores the vulnerability of millions of businesses to these attacks.
Vivek Ramachandran’s continuous research and advocacy in these critical areas have played a crucial role in raising awareness about the evolving threat landscape and driving the cybersecurity industry toward more effective and proactive defense mechanisms.
SquareX’s industry-first Browser Detection and Response (BDR) solution detects, mitigates, and threat-hunt client-side web attacks targeting employees in real time. The solution comes in the form of a lightweight browser extension that can be deployed to existing browsers via a simple group policy.
3 Components to Securing the Browser-Based Workplace
- Web Threat Detection & Mitigation: including identity attacks, malicious sites & scripts, malicious browser extensions, and malicious files
- Browser DLP: including GenAI DLP, clipboard DLP, file DLP, and insider attacks
- Private App Access: to provide secure access to web applications and private apps via the browser, including for BYOD/unmanaged devices.
Addressing the Critical Need for Browser Data Loss Prevention
Browser Data Loss Prevention (DLP) is paramount in today’s data-driven world, encompassing the crucial task of monitoring, managing, and preventing the unauthorized flow of sensitive data in and out of the browser. This encompasses a wide range of activities, including preventing data exfiltration through copy-paste, file uploads/downloads, user input, and managing access to data within SaaS applications. Furthermore, it involves robust defenses against identity attacks that could grant adversaries unauthorized access to enterprise accounts and their valuable data.
SquareX Browser DLP solution allows companies to define “sensitive” data in as granular a manner as they need to, taking into account different data access paths, identities and data complexities. Historically, enterprise data primarily resided on-premise or on local devices. However, the rapid adoption of SaaS services, particularly cloud storage platforms like Google Drive, Dropbox, and OneDrive, has dramatically shifted this landscape. In 2023, over 60% of enterprise data resided in the public cloud, a figure projected to soar to 80% by the end of the decade.
This shift necessitates heightened awareness and vigilance for security teams. They must maintain constant visibility into the flow of data in and out of their organization and possess the capability to swiftly detect and respond to data leakages in real-time. To achieve this, understanding the precise mechanism of data loss is crucial. Given the browser’s central role in employee interactions with company data, a robust Browser DLP solution like SquareX becomes indispensable for detecting, mitigating, and effectively threat-hunting data loss channels within this critical domain.
Mitigating Third-Party Risks with SquareX
SquareX’s solution includes a private access connector, which initiates a secure outbound connection to SquareX’s infrastructure, syncing policies for internal application access. Enterprises can use SquareX to configure access to internal apps granularly, on a per-user and/or per-application basis.

In essence, SquareX enables enterprises to seamlessly mitigate third-party risks—commonly linked to contractors, remote work, and BYOD—through its lightweight browser extension.
Redefining Web Security Beyond the Network Layer
Many organizations rely heavily on Secure Web Gateways (SWGs) as a core component of their SASE/SSE security suite to detect and mitigate web-based threats. These solutions primarily rely on SSL interception to identify malicious domains. Most of these solutions were invented between 10 to 15 years ago, back when web applications were relatively simpler and URL filtering was sufficient as the source of truth. They work by using network data to infer application layer attacks without truly having visibility to the application layer.
However, the limitations of this approach become increasingly apparent in today’s complex web apps environment and it is impossible to accurately do such inference without having direct access to browser metrics such as DOM changes, user interaction, site permissions, clipboard content and tab/window context.
SquareX’s solution addresses this critical gap by providing unparalleled visibility into real-time user activity within the browser. Unlike traditional network-centric defenses that often lack this crucial insight, SquareX effectively detects and mitigates risks to significantly enhance overall enterprise security.
