Zscaler Internet Access
Zscaler Internet Access (ZIA) is a cloud-native security service edge (SSE) platform that secures all internet and SaaS traffic for users, devices, workloads, and agents regardless of location. Built on the world's largest inline security cloud, ZIA inspects 100% of traffic, including encrypted SSL/TLS, to stop advanced threats and prevent data loss in real time. ZIA replaces legacy on-premises security appliances — firewalls, proxies, VPN concentrators — with a single, globally distributed platform that delivers security as close to the user as possible. With over 160 data centers worldwide, traffic is inspected locally for fast, direct-to-cloud connectivity that's up to 40% faster than traditional security architectures. Key Features and Benefits: • AI-powered threat prevention: Block malware, ransomware, phishing, and zero-day threats with real-time intelligence from 500 trillion daily threat signals. • Full SSL/TLS inspection at scale: Inspect all encrypted traffic without performance penalties, closing the blind spot that legacy tools can't address. • Defense-in-depth security stack: Multiple layers of inline threat prevention — including advanced malware analysis, web isolation, and active threat detection — stop known and unknown attacks before they reach users. • 267% ROI: Consolidate up to 90% of legacy point products — proxies, firewalls, VPN concentrators — into one cloud-native platform. • Unified management: Single console for policy creation, reporting, and analytics across all users and locations worldwide. ZIA is trusted by thousands of the world's largest organizations to deliver secure, fast, and reliable internet and SaaS access while accelerating digital transformation.
