Introducing SpinCRX: Simplified Browser Extension Security Management for the Enterprise

Managing users’ endpoints is challenging enough. But here’s a reality that’s making your job exponentially harder: your users are installing more work assistants every day in the form of browser extensions, across a number of browser types and profiles, from the same endpoints you’re working so hard to secure.

While you’ve invested in comprehensive endpoint protection, sophisticated threat detection, and rigorous access controls, there’s a growing blind spot that traditional security tools simply can’t address: the sprawling ecosystem of browser extensions that your users rely on to get their work done.

The Extension Management Dilemma

Your most productive users are always going to need the freedom to accomplish their work however they see fit. Top performers are always going to resist overly strict policies, too much red tape, or being limited to a single, secure browser. And frankly, that resistance makes business sense. Forcing users into rigid workflows often creates more problems than it solves, leading to shadow IT workarounds that are even harder to manage.

The challenge isn’t just the extensions themselves. It’s the complexity of modern browser usage patterns. Your users aren’t just working in one browser with one profile. They’re switching between Chrome, Edge, Firefox for specific applications, and Safari on their MacBooks. They’re managing multiple profiles within each browser—corporate, personal, project-specific. They’re installing extensions across all of these environments, often without understanding the security implications.

Consider this: traditional endpoint management solutions can tell you what software is installed on a device, but they can’t see into the browser extension ecosystem. Group Policy can manage some browser settings, but it can’t provide real-time risk assessment of extensions or automatically respond to threats. Mobile Device Management platforms can control app installations, but browser extensions exist in a different layer entirely.

This creates a massive visibility gap. You might have complete control over the endpoint, but you’re blind to the extensions that could be exfiltrating data, injecting malicious code, or providing backdoors into your environment. In January 2025, Cyberhaven announced that at least five of its apps were compromised by attackers, causing them to inject malicious code. Shortly after the announcement, Spin.AI researchers uncovered an additional eight malicious extensions, putting 3.7 million users at risk. Then just six months later Spin.AI researchers found 18 additional compromised extensions that had been missed in the RedDirection attack campaign, discovered roughly a week earlier. Based on Spin’s research, a total of 16.5 million people were put at risk in that campaign after having downloaded these legitimate extensions with legitimate user reviews and high ratings from the Chrome store.

The Scale of the Problem

The browser extension ecosystem has exploded in recent years, with hundreds of thousands of extensions available across major browsers. Many of these extensions request broad permissions that could compromise sensitive data. Some are outright malicious. Others start legitimate but get compromised or sold to bad actors.

What makes this particularly challenging for endpoint management teams is that extensions can be installed and removed quickly, they update automatically, and they can access data across multiple SaaS applications. A seemingly innocent productivity extension could suddenly gain the ability to read all emails, access cloud storage, or monitor keystrokes—and your traditional security tools would never know.

The rise of AI-powered extensions adds another layer of complexity. Employees are installing ChatGPT integrations, writing assistants, and data analysis tools that might be sending sensitive corporate data to external AI services. These “shadow AI” tools create compliance risks that are nearly impossible to track with conventional endpoint management approaches.

SpinCRX: Comprehensive Browser Extension Security

Your users need the freedom to leverage extensions, and you need the ability to manage them. That’s exactly why Spin.AI developed SpinCRX, an Enterprise Browser Security solution that bridges the gap between user productivity and endpoint security.

SpinCRX is purpose-built to solve the extension management challenge that traditional endpoint security tools can’t address. Here’s how it transforms browser security for enterprise environments:

1. Comprehensive Risk Assessment Across Every Browser and Profile

SpinCRX automatically assesses the risk of every extension users attempt to install—on every browser and profile. Unlike solutions that only monitor corporate browser profiles, SpinCRX provides complete visibility across Chrome, Edge, Firefox, and Safari, whether users are working in corporate profiles, personal profiles, or any combination thereof.

The solution leverages a massive repository of over 300,000 assessed browser extensions, using AI-powered analysis to provide real-time risk scoring. This isn’t just about blocking known malicious extensions. It’s about understanding the risk profile of every extension, including legitimate tools that might have overly broad permissions or concerning behaviors.

2. Risk-Based Policy Enforcement

SpinCRX applies intelligent, risk-based policies to control which extensions users can leverage on work machines. Instead of blanket restrictions that frustrate users, the solution allows you to create nuanced policies based on actual risk levels, user roles, and business requirements.

The system can automatically block high-risk extensions while allowing approved productivity tools, or it can quarantine medium-risk extensions pending review. This approach maintains user productivity while ensuring security standards are met.

3. Automated Incident Response

When risky extensions are discovered in your environment — whether they were installed before SpinCRX deployment or appeared after policy changes — the solution automatically responds based on your configured policies. This might mean immediate removal, user notification, or escalation to your security team.

The automated response capability is crucial for scaling browser security across large organizations. Instead of manually investigating every extension installation, your team can focus on policy refinement and high-priority incidents while SpinCRX handles routine enforcement.

4. Complete Endpoint Browser Visibility

SpinCRX provides visibility into all browsers and profiles accessed on managed endpoints, automatically enforcing compliance with security policies. This includes monitoring for shadow AI tools, unsanctioned SaaS applications, and data exfiltration risks across all browser activity.

The solution’s endpoint-based approach means it can enforce security policies regardless of which browser profile a user is accessing. Even if someone switches to a personal profile on their work device, SpinCRX continues to monitor and protect against risky extensions that could impact your corporate environment.

5. Streamlined Approval Workflows

SpinCRX includes built-in approval processes that make new extension requests fast and easy for both users and administrators. When a user wants to install an extension that requires approval, they can submit a request directly through the interface. Administrators can quickly review the risk assessment, understand the business justification, and make informed decisions without lengthy back-and-forth communications.

Flexible Deployment for Your Environment

Understanding that every organization has different endpoint management approaches, SpinCRX offers flexible deployment models:

Agentless Monitoring: Deploy via user profiles for organizations that primarily need to monitor and manage corporate browser profiles. Users authenticate once, and SpinMonitor works quietly in the background across their corporate browsing activity.

Endpoint-Based Monitoring: Deploy directly to managed endpoints for comprehensive control across all browser profiles accessed from work devices. This approach ensures that personal profiles can’t inadvertently compromise corporate security through risky extension installations.

Many organizations benefit from a hybrid approach, using agentless monitoring for contractors on unmanaged devices and endpoint-based monitoring for full-time employees on corporate hardware.

Integration with Your Existing Security Stack

SpinCRX isn’t meant to replace your existing endpoint management tools. Rather, it’s designed to extend them. Leveraging API integrations the solution integrates with leading security platforms like CrowdStrike and Splunk, as well as alerting and response management platforms like ServiceNow, Jira, Slack, Teams, and more. This means browser security events can flow into your existing incident response workflows, and policy violations can trigger alerts in your preferred tools.

As part of the broader SpinOne SaaS Security platform, SpinCRX also provides contextual security insights by correlating browser-level risks with actual data access patterns in Google Workspace™, Microsoft 365, and other SaaS applications.

The Path Forward

Browser extension management represents a critical evolution in endpoint security strategy. As SaaS adoption continues to grow and AI-powered tools become ubiquitous in the workplace, the traditional perimeter-based security model becomes less effective. Organizations need solutions that can provide visibility and control within the browser itself—the primary interface for modern knowledge work.

SpinCRX addresses this challenge by extending your endpoint management capabilities into the browser extension ecosystem. It provides the granular control and visibility you need while preserving the user experience that drives productivity.

For CIOs and endpoint management teams, the question isn’t whether browser extensions will continue to proliferate — it’s whether you’ll have the tools to manage them effectively. SpinCRX ensures that browser security becomes a strength of your endpoint management strategy rather than a blind spot.

The modern workplace demands both security and flexibility. With SpinCRX, you can deliver both.
