From Gateway to Target: How the Browser Became the #1 Attack Surface and How Dizzion Halo Fixes It

Today, about 80% of work happens inside the browser. It’s where we check email, access critical SaaS platforms, use collaboration tools, search the internet, use Google Gemini, ChatGPT, and interact with internal business apps. Despite that, the browser is still one of the least protected parts of the workspace. That’s like putting the crown jewels in a shoebox and leaving it on the doorstep.  

The browser is the front door to the business. It touches nearly every SaaS and web application, yet it remains the largest unprotected attack surface for most organizations. Why? Because the security stack hasn’t kept up.

Legacy tools like Antivirus, Secure Web Gateways, VPNs, and perimeter firewalls were built for a different era; they were not designed for:

• AI-driven tools and risky browser extensions
• Cloud-first adoption
• SaaS as the primary application layer
• BYOD and unmanaged devices
• Contractors and third-party access
• A workforce that can be anywhere, on any device

In other words, old security tools weren’t built for a browser-first world. That’s why Secure Enterprise Browser solutions are developed.

Introducing Dizzion Halo

Dizzion Halo solves this gap. Halo is a Secure Every Browser (SEB) solution, not just for enterprises. Instead of forcing users into new workflows, it turns the browsers they already use (Chrome, Edge, Firefox, and Safari) into enterprise-grade security endpoints.

For IT pros, that means no retraining, no parallel toolset, no additional application to be installed, and no fighting with end users about why they “have to switch browsers.”  For security teams, you finally have visibility and control over an environment that attackers target daily.

And it’s not coming from a new player. Dizzion has a long history of delivering secure, high-performance desktops and applications with DaaS and Cloud PC. Halo extends that proven security model to the local browser, the enterprise's most widely used but least protected endpoint.

What IT Gets with Halo

• Access control and protection: Enforce zero-trust access down to the user, device, and risk context. Apply granular DLP rules to copy/paste, uploads, and downloads. Real-time detection blocks malware, phishing attempts, and unusual activity before it spreads.
• Visibility and governance: Get full visibility into SaaS usage, shadow IT, and browser extensions. Automatically discover and risk-score extensions, centralize monitoring, and restrict access to thousands of web and AI tools that may introduce risk.
• Fast deployment anywhere: Deploy in minutes without replacing browsers or forcing users into a new workflow. Works as a standalone solution on any device or integrates with Dizzion DaaS and Cloud PC for a complete workspace stack.

Why It Matters

Halo is not another heavy, complex security layer or an Enterprise Browser solution like Island. It eliminates the need for over-engineered approaches like remote browser isolation (RBI) or classic VDI to secure SaaS apps.

Think of a few real-world scenarios IT teams deal with every day:

• Contractors with unmanaged devices; usually a headache, often solved with expensive VDI. With Halo, they can work securely in their own browser without spinning up full virtual desktops or apps.
• BYOD programs; personal devices no longer mean blind spots. Halo enforces policies and DLP directly in the browser session.
• Zero-trust adoption; Halo adds the missing layer. You may already have network controls, identity, and MFA in place, but the browser itself still needs protection. Halo closes that gap.
• Extension chaos; risky browser plugins and AI tools are spreading fast. Halo auto-discovers and risk-scores extensions so you can manage them proactively.

For IT pros, this means fewer moving parts, less overhead, and a solution that directly maps how work is done today: in the browser.

The Bigger Picture

Halo isn’t standalone in strategy. Together, Halo, DaaS, and Cloud PC give you flexibility:

• Use DaaS and Cloud PC when you need full Windows or Linux desktops, specialized apps, or controlled network access.
• Use Halo when the goal is secure, compliant access to SaaS and web applications without DaaS or Cloud PC infrastructure.
• Combine them for a browser-first workspace that is secure by design, simple to manage, and cost-efficient to scale, delivering web, SaaS, Windows or Linux desktops or Apps.

This layered approach means you’re not locked into one model. Instead of forcing every use case through the same technology stack, you can apply the right tool for the right job.

Bottom Line

The browser is no longer just a tool, it is the new security perimeter. Users spend most of their time there, and attackers know it. Protecting it should be a top priority of modern IT strategy. Your browser is the new security perimeter. Secure it with Dizzion Halo.
