Your Firewall Cannot Follow Your Employees Home. But Cloud Secure Edge Can.

The Same Protection as Your Firewall, Extended to Every Remote User

 

 

Firewall security has been a cornerstone of network protection for decades, and for good reason: firewalls inspect traffic, enforce web filtering policies, and block threats before they reach a device. But what happens when employees step outside the corporate perimeter? Outside the office, that carefully configured firewall protection is simply no longer in the path. Remote workers frequently browse and download files without any network-layer protection from threats. As remote and hybrid work become the norm, this creates a real and increasing risk for both organizations and users. 

The Gap Between the Firewall and the Endpoint 

Security teams typically address this gap with endpoint detection and response (EDR) tools installed directly on devices. EDR is a valuable and necessary defense layer, but it is designed to detect and respond to threats that have already reached the device. By the time EDR acts, a malicious file has landed on the endpoint and may have already begun executing. 

As the saying goes, the best defense is a good offense, and the same principle applies to cybersecurity. Stopping malware at the network level before it reaches the device significantly reduces risk. EDR remains an essential safety net, but remote workers now require the same in-path, network-level protection that in-office employees already receive. 

Cloud Secure Edge: Extending Network-Level Protection to Every User, Everywhere 

SonicWall Cloud Secure Edge (CSE) closes this gap by extending the same internet access protection your firewall provides to every device, regardless of where users connect. Rather than anchoring protection to a fixed network edge, CSE moves the inspection point to the device itself. Whether an employee is working from home, a hotel, or a co-working space, the same web filtering, threat intelligence, and Capture ATP file analysis that protects on-network users follows them. The same controls security teams configure on the firewall are now enforceable at the device level, including category-based content filtering, geo-IP blocking, URL and domain allow/block policies, new domain detection, and malicious domain blocking. Remote employees receive consistent, enterprise-grade protection without requiring them to be on the corporate network. 

Capture ATP Now Available in CSE 

SonicWall Capture Advanced Threat Protection (ATP) has powered malware detection on SonicWall firewalls and endpoint solutions for years. This award-winning technology is a cloud-based, multi-engine sandbox that simultaneously inspects files from four angles: 

  • Real-Time Deep Memory Inspection (RTDMI) operates at the memory level, forcing malware to reveal its weaponry in-memory rather than waiting for it to exhibit observable behavior. This is particularly effective against threats that are encrypted, dormant, or specifically designed to avoid triggering behavioral sandboxes.
  • Hypervisor-level analysis provides visibility into execution at the hardware abstraction layer, below the operating system, where most evasion techniques have no reach.
  • Full system emulation replicates the target environment and observes how the file behaves across multiple operating systems, exposing threats that are environment-specific or time-delayed in their execution.
  • Virtualized sandboxing executes the file in an isolated environment and monitors for indicators of compromise network calls, registry modifications, process injection, and other behaviors that distinguish malicious from benign.

The result is a detection capability that has earned perfect scores in independent third-party testing across multiple consecutive cycles, consistently outperforming competing vendors.  SonicWall CSE extends this same Capture ATP engine directly into the cloud-delivered security layer, operating on the device via the CSE client. 

CSE Secure Internet Access is not a replacement for the SonicWall firewall. Users on the corporate network, protected by a SonicWall Next-Generation Firewall with Capture ATP, remain fully protected. That layer of defense continues to operate exactly as designed. What CSE adds is coverage for users, devices, and traffic that fall outside the firewall's reach, which in most organizations today represents a substantial and growing portion of the workforce. Together, the firewall and CSE deliver complete coverage: perimeter protection for network-bound traffic, and device-level protection for everything else.  

The same Capture ATP engine. The same detection capability. Now extended to every remote user. 

Compliance in the Age of Remote Work 

The security gap that CSE addresses carries particular weight in regulated industries, where remote worker protection is not just a best practice but a compliance obligation. The same protection standards that govern on-network users apply equally to employees working from home, traveling, or connecting from outside the corporate perimeter. Here are the top concerns that CSE Secure Internet Access can help address: 

  • Healthcare: HIPAA requires covered entities and their business associates to implement technical safeguards protecting patient data, including when accessed by remote clinical and administrative staff.
  • Financial Services: PCI DSS, GLBA, and frameworks such as NYDFS 23 NYCRR 500 mandate robust controls over systems handling cardholder and customer financial data both on-network and off. 
  • Retail: PCI DSS applies to any organization accepting card payments. Distributed workforces without consistent in-path protection create a measurable compliance surface area. 
  • Education: FERPA holds institutions responsible for how student records are protected, including when accessed by remote staff or third-party vendors operating on their behalf. 
  • Global Operations: GDPR applies to any organization handling EU resident data, with fines reaching €20 million or 4% of global annual turnover for non-compliance. 

One Toggle. Complete Coverage. 

CSE Secure Internet Access extends that coverage to every user, on every network, without adding operational complexity. A single toggle in the CSE console enables inline malware inspection across your remote workforce. There is also no DPISSL certificate to deploy. The CSE client handles TLS inspection natively, with centralized exclusion management rather than per-site configuration. 

Your remote workforce does not have to be your biggest security gap. Request a demo of SonicWall Cloud Secure Edge today and extend the same protection your network relies on to every user, everywhere.
