SASE Alone Won’t Cut It—Why You Need a Secure Enterprise Browser

Secure Access Service Edge (SASE) has transformed enterprise security, offering a unified approach to securing cloud environments. It reduces reliance on legacy security tools and simplifies network access controls. But while SASE is great at protecting network traffic, it doesn’t address a significant security gap: what happens inside the browser.

The browser is now the primary workspace for employees, yet most security strategies fail to account for the risks that come with it. Attackers don’t need to breach the network when they can simply compromise a browser session, steal authentication tokens, or exploit unmonitored extensions. If enterprises don’t secure the browser alongside SASE, they’re leaving a critical blind spot wide open.

The SASE Blind Spot: What Happens Inside the Browser

SASE secures traffic in transit, but it doesn’t provide visibility or enforcement inside an active browser session. That means:

• Session Hijacking Still Works – If an attacker steals a session token, they can bypass SASE protections and access corporate applications without detection.
• Phishing Attacks Remain a Risk – A user clicking a malicious link while authenticated can still hand over credentials without triggering SASE alerts.
• Malicious Extensions Operate Undetected – 51% of enterprise browser extensions are classified as high-risk, capable of exfiltrating sensitive data, injecting malicious code, or facilitating unauthorized access.

These risks become even more apparent as enterprises shift further into SaaS and cloud-based workflows. Organizations are leaving a critical gap in their security strategy without securing the browser itself.

How Primary’s Secure Enterprise Browser Strengthens SASE

To fully secure an enterprise, security must follow the user into the browser. That’s where Primary’s Secure Enterprise Browser comes in. By working alongside SASE, Primary extends security beyond the network and into the user’s workflow.

Key Benefits of Integrating a Secure Enterprise Browser with SASE

• Session Integrity Protection – Even if an attacker steals login credentials, they can’t hijack an active session—continuous authentication ensures only the legitimate user stays logged in.
• Zero Trust at the Browser Level – Security isn’t just about network access. Every user action inside the browser is verified in real time to prevent unauthorized access.
• Malicious Extension Prevention – Primary blocks unapproved browser extensions, preventing unauthorized data leaks, keylogging, and code injection.
• Policy Enforcement Inside the Browser – Security policies don’t just apply at the network level—they follow users directly into SaaS applications and web sessions, ensuring data loss prevention (DLP) and risk-based access control at the point of interaction.
• Reduced Overhead, Stronger Security – Unlike traditional security tools that add friction for users, Primary’s Secure Enterprise Browser enforces security while maintaining a seamless browsing experience—without requiring extensions or additional security layers.

SASE + Secure Enterprise Browser = A Complete Security Strategy

SASE is a powerful security framework, but it was never designed to secure the browser. Attackers know this, which is why they increasingly target browser-based threats that bypass traditional network defenses.

By integrating a Secure Enterprise Browser with SASE, organizations can enforce security policies from the network edge all the way to the application layer without disrupting users.
