Following our recent announcement regarding the evolution of Privileged Remote Access into Secure Agentless Access (SAA), we are thrilled to introduce the next major leap in our true agentless security architecture: Natively integrated Remote Browser Isolation (RBI) for Secure Agentless Access to SaaS and Private Web Applications with Data Protection controls.
The Unmanaged Device Dilemma: Accessibility vs. Control
As modern enterprises transition toward distributed workforces, contractors, and third-party vendors, securing access across unmanaged endpoints has become a central challenge. Today, nearly 48% of organizations have experienced data breaches linked directly to BYOD devices.
Historically, security teams relied on a limited set of trade-offs to manage unmanaged device access:
- Legacy Virtual Desktop Infrastructure (VDI): Expensive to license, complex to manage, and delivers a degraded user experience by streaming an entire desktop when users only need access to web applications.
- CASB Reverse Proxies: Prone to breaking complex web application layouts, leading to high support ticket volumes and user frustration.
- Dedicated Secure Browsers: While many agent based solutions provide the ultimate deep-security controls for managed and unmanaged workloads, certain third-party contractors or strict enterprise environments cannot mandate installing software on local devices.
This creates a critical operational gap: How do you deliver strict Zero Trust data controls without requiring any endpoint installations?
The Solution: A Pure "Browser in the Cloud" Experience
The integration of Remote Browser Isolation (RBI) with Secure Agentless Access (SAA) bridges the gap between total accessibility and uncompromising Zero Trust security. This combination provides a completely clientless mechanism to secure both private web applications and critical SaaS applications without leaving a footprint on the endpoint, while delivering a near-native streaming end-user experience.
Key Benefits of Integrated SAA + RBI
This unified capability unlocks a new tier of Zero Trust capabilities, ensuring that your organization's data remains secure, regardless of who is accessing it or from what device.
- Data Exfiltration Controls for SaaS Apps and Private Web Apps: SaaS applications can now be securely accessed from any device, anywhere in the world. RBI enforces granular contextual guardrails directly within the browser session. Administrators can restrict clipboard actions (cut, copy, paste), block printing, restrict keyboard inputs, and control file uploads/downloads to prevent corporate data leakage on unmanaged devices.
- True "No Agent" Architecture: Requires absolutely zero endpoint software. Organizations can protect workflows without local agents, PAC files, custom proxy configurations, dedicated browsers, or Mobile Device Management (MDM) enrollment.
- Shielding Crown Jewel Private Web Applications: Threat actors can't scan, map, or probe your private web resources because Private web resources remain invisible to the public internet, stripping away server-side metadata and preventing threat actors from probing internal infrastructure.
- Instant Onboarding & Management: Provisioning access for contractors, temporary workers, or acquired employees is instantaneous. IT teams can centrally enforce access policies without managing endpoint deployment pipelines or troubleshooting local device compatibility.
- Consistent IP Whitelisting for Unmanaged Devices: Untrusted devices never connect directly to sensitive SaaS applications Instead, the remote browser egresses via Prisma Access or a ZTNA connector, enabling organizations to seamlessly maintain strict IP whitelisting rules across all endpoints.
Strategic Use Cases
The combination of SAA and RBI addresses four high-impact enterprise scenarios:
- BYOD & Contractor Enablement: Empower your extended workforce—contractors, partners, and BYOD employees—to access critical SaaS and private web applications from any device, driving productivity without compromising corporate data boundaries.
- VDI Alternative / Replacement: Replace complex, costly Virtual Desktop Infrastructure (VDI) with a lightweight, browser-native approach. For organizations using VDI primarily to deliver web applications, SAA + RBI eliminates steep licensing fees, infrastructure overhead, and session latency—delivering a seamless, near-native user experience.
- Business Continuity & Disaster Recovery (BCP/DR): Establish a resilient, zero-footprint fallback access channel for critical enterprise applications. During an endpoint outage, hardware loss, or emergency scenario, employees can rapidly and securely reconnect to essential SaaS and private web apps from unmanaged backup devices using SAA + RBI.
- Mergers & Acquisitions (M&A): Bypass slow, complex M&A IT integrations—such as hardware distribution and domain trust setups. SAA + RBI enables instant Day-1 access for acquired employees on their existing devices, eliminating hardware friction and accelerating time-to-value.
Elevate Your Zero Trust Architecture Today
Remote Browser Isolation combined with Secure Agentless Access fulfills the promise of true Zero Trust for the modern enterprise. By removing endpoint friction, organizations can confidently support BYOD initiatives, accelerate third-party workflows, and neutralize web-borne threats before they reach the endpoint.
