Appliance-based SWGs increase your risk of compromise because they can’t inspect 100% of TLS/SSL-encrypted traffic—a must now that ~95% of traffic is encrypted.

Latency issues

Appliance-based SWGs slow down and create poor user experiences when bandwidth- and connection-intensive applications like Microsoft 365 overwhelm their processing limitations.

Maintenance and scalability challenges

Your team is always burdened with the need to manually manage patches, upgrades, and change windows. When you fall behind, it’s exponentially harder to catch up.

The Solution

Transform your security with a fundamentally different architecture

As the world’s leading secure web gateway (SWG), Zscaler Internet Access™ delivers cloud native, AI-powered cyberthreat protection and zero trust access to the internet and SaaS apps. Our proxy architecture enables full TLS/SSL inspection at scale, with connections brokered between users and applications based on identity, context, and business policies.
Offered as a scalable SaaS platform through the world’s largest security cloud, it replaces legacy network security solutions, preventing advanced attacks and data loss with a comprehensive zero trust approach.

Form factor

APPLIANCE-BASED: Inherently capacity-limited, boxes can’t scale performance without adding more appliances.

CLOUD NATIVE: Eliminate the need for appliances with a cloud native proxy architecture with infinite scale.

TLS/SSL inspection

LEAVES YOU AT RISK: Nearly all web traffic is encrypted, but appliances can’t inspect it effectively, putting you at risk when 85.9% of threats are delivered over encrypted channels.

LEAVES NOTHING HIDDEN: Inspect 100% of TLS/SSL traffic inline, without degrading performance or compromising on effective security.

Threat prevention

CAN'T KEEP UP: Appliances need constant upgrades and updates to keep pace with adversaries using automated tools and novel evasion tactics.

ALWAYS UP TO DATE: Drastically reduce your attack surface with the power of the cloud—get 250K+ daily security updates sourced from 320B daily transactions across the entire security stack.

Malware analysis

PASSTHROUGH INSPECTION: Unknown and suspicious files pass through the proxy without inline inspection, leaving the network exposed to a variety of attacks.

AI/ML-BASED QUARANTINE: Stop and quarantine zero-day attacks—even if they’re hidden in TLS/SSL traffic—preventing them from reaching their targets with inline detection with AI/ML-based analysis.

Ransomware

TOO MANY BLIND SPOTS: Traditional appliances can’t fully inspect encrypted traffic, and since almost 86% of threats are encrypted, ransomware gets into your network undetected.

COMPREHENSIVE PROTECTION: Expose, isolate, and stop ransomware in its tracks, regardless of user, location, or network, with 100% inspection of TLS/SSL traffic at scale.

Remote workforce

UNABLE TO SCALE: Appliance-based approaches can’t scale adequately to secure a large remote workforce, making security policy management complex and cumbersome.

INFINITE SCALE: Auto-scale and frictionlessly transition security policies to protect users anywhere with a cloud native architecture.

Microsoft365

POOR USER EXPERIENCES: Appliances bottleneck cloud apps like Microsoft 365 that depend on throughput and sessions with other hardware controls, leading to poor user experiences.

SUPERIOR PERFORMANCE AND PRODUCTIVITY: Give users a direct, secure connection to Microsoft 365 with one-click configuration, delivering optimized performance and a more productive user experience.

Administration

TEDIOUS: Dealing with hardware configuration issues and inconsistent policies across the network and remote users wastes a lot of time.

STRAIGHTFORWARD: With the network out of the equation, focus on creating context-based business policies that are enforced consistently, everywhere, without any hardware constraints.
