Zscaler Internet Access is a cloud-based security service edge from Zscaler, offering DNS filtering, content filtering, and advanced threat protection for enterprise networks. The platform replaces traditional on-premises firewalls and proxies with a cloud-native architecture built on zero trust principles, inspecting 100% of encrypted TLS/SSL traffic and applying dynamic policies based on user identity and device context. It is positioned as enterprise infrastructure serving organisations with 200 or more employees.
The solution covers DNS-layer blocking with threat intelligence feeds, content category filtering for policy enforcement, threat protection against ransomware and advanced malware, data loss prevention with cloud DLP and cloud access security broker capabilities, and roaming protection for off-network devices through cloud agents deployed on endpoints. Multi-tenant management enables administration across distributed sites and subsidiaries, with per-site policy configuration and comprehensive audit reporting for compliance and incident investigation.
Zscaler Internet Access uses custom quote-only pricing with no published per-user, per-endpoint, or per-site rates available. The company does not publish a free trial, though enterprise customers can arrange evaluation through the sales team. Annual billing and volume discounts are typical for large enterprise customers. Integration occurs through APIs and connectors with SIEM, SOAR, and XDR platforms for security operations centre workflows. Zscaler operates an MSP partner program for managed service providers handling enterprise accounts, though direct integration with RMM systems such as NinjaOne or Datto RMM is not currently documented.
The company was founded in 2007 and is headquartered in San Jose, California. Before committing, enterprises and MSPs managing large customers should verify that security compliance requirements support cloud-only deployment, confirm integration with existing SIEM and ticketing systems, evaluate the cloud agent deployment model for remote endpoints, and confirm cost positioning versus other enterprise security service edge platforms from vendors such as Cloudflare or Palo Alto Networks.
Zscaler Internet Access positions itself as an enterprise security service edge rather than as an MSP-focused DNS filter, so suitability depends on customer size and cloud commitment. It excels at replacing legacy firewall infrastructure for large enterprises with multi-site networks, offering integrated threat protection, data loss prevention, and compliance reporting. Compare against other enterprise SSE platforms like Cloudflare Gateway or Palo Alto Networks, rather than against traditional MSP DNS filters. Verify that the customer's compliance requirements support cloud-only deployment, confirm integration with existing SIEM and ticketing systems, and discuss the cloud agent deployment model for endpoints outside the customer's network.

Zscaler Internet Access is designed as an enterprise-focused security service edge for organisations with 200 or more employees. MSPs serving smaller customers should evaluate traditional MSP DNS filters. However, Zscaler Internet Access does operate an MSP partner program for managed service providers managing large enterprise customers, with dedicated partner resources and integration support.
Zscaler Internet Access is a cloud-based security service edge that combines DNS filtering with threat protection, data loss prevention, and identity-based access control. Unlike traditional DNS-only filters deployed on-premises or via routers, Zscaler Internet Access inspects 100% of encrypted traffic in the cloud and enforces zero trust policies based on user identity and device context, eliminating the need for legacy firewall infrastructure.
Zscaler Internet Access uses custom quote-based pricing with no published per-user, per-endpoint, or per-site rates available. Enterprise customers report significant cost savings from consolidating firewall, proxy, and DLP functionality into a single cloud platform. Contact Zscaler sales directly for specific pricing based on your environment, geography, and feature requirements.
Zscaler Internet Access is a cloud-only platform with no on-premises or hybrid deployment options. Users and devices connect to Zscaler's cloud infrastructure for traffic inspection and policy enforcement. The platform supports roaming clients through cloud agents for off-network devices and multi-tenant dashboards for centralized management across distributed locations and subsidiaries.
Zscaler Internet Access primarily integrates with security operations centre tools including SIEM, SOAR, and XDR platforms for incident response and threat analysis workflows. Direct integration with RMM systems is not currently documented. Zscaler Internet Access does operate an MSP partner program, and custom integrations or API-based connections may be available through professional services engagement.
