Reimagine cybersecurity for a world without perimeters

Cybersecurity spending has never been higher, yet high-impact ransomware, supply-chain attacks, and other sophisticated threats continue to breach enterprises.Legacy network security architectures are no longer effective due to:

  • A dramatically expanded attack surface that extends to home offices, cloud apps, and public clouds

  • Sensitive data that is distributed everywhere and must be protected from exposure and theft

  • Threats hiding within encrypted traffic, which makes up >90 percent of all internet communications

Reimagine cybersecurity for a world without perimeters

Transform your cyberthreat protection

The Zscaler Zero Trust Exchange stops the most sophisticated threats and holistically reduces business risk with a groundbreaking cloud-native security architecture.

Stop breaches

Get peace of mind with a comprehensive platform that delivers full inline inspection, zero trust access control, and AI-powered threat prevention.

Eliminate complexity

Replace complex castle-and-moat security with an integrated platform delivered from the cloud with unlimited scale—and with no deployment or appliances.

Get dynamic protection

Monitor, control, and secure all traffic for all users in all locations with consistent protection built for today’s cloud-first, hybrid workforce.

Traditional approaches have become irrelevant for the cloud-first world

Legacy castle-and-moat security architectures built on firewalls have become a barrier to effective risk reduction.

77% of alerts are false positives

The average time to detect and mitigate a breach is 280 days

500% increase in attacks delivered over encrypted traffic

Cybercrime will cost the global economy $6 trillion in 2021

Zscaler Zero Trust Exchange

The Zscaler Zero Trust Exchange is a fundamentally different approach to ransomware protection, with unmatched attack surface reduction, AI-powered threat protection, and lateral movement prevention. Users, devices, and workloads connect directly to the resources they need, with full inline security controls that operate at the speed of the cloud.

Zscaler Zero Trust Exchange

The world’s most comprehensive cyber-risk reduction platform

As the world’s only true zero trust platform, Zscaler sits as an exchange between users, the internet, and applications, providing unmatched protection at every stage of the attack lifecycle.

Eliminate the attack surface

Eliminate the attack surface

Prevent attackers from discovering or exploiting apps by making them invisible and only accessible to authorized users or devices through the Zero Trust Exchange.

Eliminate the attack surface

Prevent compromise

Protect users, servers, applications, and connected devices no matter where they are with full traffic inspection and AI-powered security at the edge.

Eliminate the attack surface

Stop lateral movement

Connect users and devices directly to apps without ever exposing the network. Misdirect attackers and learn of their presence with proactive lures and decoys.

    Zscaler accelerates CSR’s security transformation

    Hear from CSR’s Security Architect, Dave Edge, on how Zscaler helps reduce risk in an ever-expanding threat landscape.


    “We’ve completely changed the cybersecurity posture of the State of Oklahoma in the last 18 months – Zscaler played a big part in that.”

    Matt Singleton, CISO, Office of Management and Enterprise Services, State of Oklahoma


    “When ransomware attacks happen to other companies, thousands of systems in their environment are crippled, in addition to having serious impacts with having to pay a ransom. When this kind of event hits the news, I get worried calls from executives, and it warms my heart to be able to tell them, ‘We’re fine.’”
