Check Point SASE: Multilayer Secure Access Architecture Practical Use Cases Illustrating How to Protect the Modern Enterprise

MULTILAYER SECURE ACCESS ARCHITECTURE

Executive Summary

The modern enterprise runs in the browser. Employees draft documents, access SaaS applications, collaborate in real time, and move between tasks entirely through web-based tools. While this shift has improved productivity and organizational agility, it has also created new security blind spots that traditional network-centric models cannot address. Most work now takes place outside the traditional perimeter – across home networks, coffee shops, partner environments, and unmanaged contractor devices. The browser itself has become a high-value target, capable of executing code from multiple sources simultaneously. Malicious downloads, embedded scripts, and compromised documents are common entry points for attackers.

Simultaneously, corporate data flows have become more fluid and difficult to control. Users regularly move sensitive information through SaaS interfaces, personal devices, clipboard actions, file uploads, downloads, form fills, and increasingly into generative AI tools – all of which fall outside the visibility of legacy DLP and firewall solutions. These challenges are top of mind for the security teams tasked with protecting modern distributed workforces. While not exhaustive, the use cases below illustrate the core patterns organizations must address: securing browser-based workflows, controlling data movement, and enabling safe access across both managed and unmanaged devices. Check Point SASE’s multilayer secure access architecture brings these elements together. Rather than relying solely on network inspection or device agents, the architecture applies controls at multiple points – in the browser, on the device, and across a global cloud security fabric – to deliver consistent protection regardless of where or how users work.

The New Enterprise Reality

Employees today use the browser as their primary interface with the business. Work that once depended on dedicated applications is now performed inside cloud and SaaS platforms like Google Docs, Salesforce, Monday, Office 365, WebEx, and Adobe Creative Cloud. This browser-first environment supports flexible, collaborative workflows across distributed teams. A user can draft content, manage a CRM pipeline, join a meeting, upload files, and collaborate on presentations – all without leaving the browser. Remote work amplifies this model, with the browser acting as the bridge between users and corporate resources from any location.

But the browser’s openness introduces substantial risk. Its ability to load and execute content from many sources – ad networks, third-party scripts, embedded documents, and dynamic code – creates fertile ground for sophisticated attacks. Threat actors exploit temporary downloads, malicious JavaScript, and file-based payloads, many of which bypass traditional perimeter defenses. Meanwhile, unmanaged devices are now part of daily operations. Contractors, freelancers, and BYOD users routinely access corporate applications without the protections found on managed corporate laptops. Organizations often lack visibility into the security posture of these devices, increasing the chances of data leakage or compromise. These changes have stretched legacy security models beyond their limits. Network appliances cannot see inside the browser. VPNs provide overly broad access. Traditional DLP cannot govern in-browser actions like copy/paste, file uploads, cloud-to-cloud interactions, or form submissions. Enterprises need a new approach – one that addresses real-world workflows rather than legacy network boundaries.

Fluid Data Movement

Fragmented Security Controls Data may move from a SaaS app to a local download, into a clipboard, into a personal device, or into an AI tool. Traditional DLP struggles to inspect or control these flows. Network security, endpoint security, identity systems, and cloud access tools often operate in isolation. Without coordination, gaps emerge between layers.

The Gaps Security Teams Must Address

Despite their investments in network inspection, identity security, and endpoint tools, organizations still face four persistent gaps:

  1. Blind Spots Inside the Browser
    Most security tools struggle to see or govern the actions users take inside the browser – where sensitive data is copied, pasted, uploaded, downloaded, or moved between applications.
  2. Unmanaged and Semi-Managed Devices
    Contractors, third parties, and BYOD users frequently access corporate resources using devices without corporate controls. Agent deployment is often impossible or impractical.

Use Case #1: Securing Corporate Employees Across SaaS & Cloud

Corporate employees rely heavily on SaaS applications and web-based tools to complete daily work. Even with managed devices, most of their activity still takes place inside the browser, where traditional network or endpoint security has limited visibility. Remote and hybrid work amplify this with users connecting over networks outside the organization’s control.

Challenges

Solution Approach

Combine device-level prevention, browser-level governance, and cloud-delivered inspection to protect all user activity across SaaS, web, and internal applications.

Capabilities Supporting This Use Case

Outcome

Corporate employees gain fast, reliable access to cloud applications with comprehensive protection across device, browser, and network layers – without impacting productivity.

Use Case #2: Securing Unmanaged Devices (Contractors & BYOD)

Contractors and employees using their own devices access corporate applications from environments that the organization does not control. These unmanaged devices introduce similar types of risks: no endpoint agent, no visibility into system posture, and no reliable way to enforce data-handling policies.

Challenges

Solution Approach

Create an isolated, controlled browser workspace or deliver access through cloud-delivered controls on any device, without an agent. This ensures unmanaged devices can safely reach approved applications without exposing the broader environment.

Capabilities Supporting This Use Case

Organizations gain visibility and control over sensitive data across all browser-based workflows, preventing accidental or intentional leakage into SaaS, AI tools, or unmanaged environments.

Use Case #3: Data Protection & Governance in the Browser

Modern workflows involve constant data movement through the browser, such as copying, pasting, uploading, downloading, filling forms, and interacting with cloud applications. Traditional DLP tools cannot see or control many of these in-browser actions, leaving gaps in data governance across SaaS environments.

Challenges

Solution Approach

Apply data loss prevention policies directly in the browser – where sensitive actions occur – and reinforce them with cloud inspection and device-level controls.

Capabilities Supporting This Use Case

Users gain secure, role-appropriate access to internal systems without exposing the broader environment, while data and in-app actions remain governed at the browser level.

Use Case #4: Zero Trust Access to Internal Applications

Internal applications are critical to business operations, yet traditional access controls often fall short. Legacy VPNs provide overly broad connectivity, increasing the chance of lateral movement, while identity-only controls lack sufficient context for secure access.

Challenges

Solution Approach

Deliver per-application Zero Trust access for managed and unmanaged devices while governing in-browser actions to prevent data leakage or unauthorized behavior.

Pulling the Use Cases Together – A Unified Architecture

Across these scenarios, several patterns emerge:

This unified model applies security policies consistently – including controls that prevent sensitive information from flowing into external AI systems – regardless of device, network, or application. Unified Operations Through the Check Point Portal The Check Point Portal centralizes visibility and control across all protection layers, allowing administrators to monitor browser activity, device posture, and cloud traffic from a single interface. This makes scaling – to new users, locations, or applications – effortless thanks to the cloud-delivered model.

Why Check Point

Work happens in the browser, on every type of device and across a wide mix of apps and cloud services. Protecting this reality means using security that fits how people actually work today, not relying on outdated, network-centric assumptions.
