Minimize your attack surface and become invisible to attackers with Zscaler.

Firewalls and VPNs expand your network attack surface with open ports and public IPs for attackers to discover. 

 

With Zscaler, there are no public IPs or open listening ports. Our cloud native proxy architecture enables full TLS/SSL inspection at scale, with zero trust connections brokered between users and apps based on identity, context, and business policies.

 

  • Eliminate exposed devices and IP addresses. Hide users, branches, and factories behind the Zscaler Zero Trust Exchange™ platform.
  • Enforce zero trust app access. Connect users directly to authorized apps, not networks—and eliminate lateral threat movement.
  • Get holistic attack surface management. See a complete view of vulnerabilities, TLS/SSL weaknesses, and what’s exposed to the web.

The Problem

Every public IP and open port is a potential entry point for threats

Open ports and public IP addresses are the unavoidable consequence of a perimeter-based, network-centric architecture. Every one of them represents a vulnerability attackers can probe, exploit, or try to brute-force credentials against. Once attackers gain access, they can move laterally across flat networks and escalate privileges.
