Availability and resilience

• Guaranteed availability: Zscaler guarantees industry-leading service availability through its cloud-native, multi-tenant architecture with more than 160 globally distributed nodes. The platform offers a 99.999% service level agreement (SLA) for availability, ensuring that users experience virtually uninterrupted access to security services and business-critical applications—even under heavy global demand.; ; If Zscaler fails to meet its SLA for availability, the customer is typically entitled to compensation as outlined in their contract. This usually takes the form of service credits or refunds, calculated based on the degree and duration of the outage compared to the agreed SLA. The process for obtaining compensation requires the customer to submit a request in accordance with contract terms, and service credits are then applied to future invoices or fees. However, the specific terms—including eligibility, calculation formula, and limits—are determined by each customer’s individual agreement with Zscaler.; ; Overall, Zscaler’s robust architecture and high SLA minimize downtime risk, and their contractual remedies provide reassurance that customers are protected financially if service levels are not met.
• Approach to resilience: Zscaler is engineered for resilience through its cloud-native, multi-tenant architecture and extensive global footprint—comprising over 160 distributed nodes.

The platform’s redundancy and failover capabilities safeguard security services against outages and disruptions, supported by a 99.999% availability SLA that guarantees extremely reliable access to business-critical applications and data.; ; Each security service is delivered directly from the cloud rather than relying on potentially vulnerable on-premise hardware, minimizing single points of failure. Zscaler’s distributed infrastructure eliminates bottlenecks, providing automatic load balancing and disaster recovery to keep users protected and connected. High availability DNS integration and elastic resource allocation further enhance continuity, ensuring that core functions remain operational even during maintenance or unexpected events.; ; In summary, Zscaler’s resilient architecture protects users from service degradation caused by external factors or other tenants on the platform, maintains security and productivity, and delivers industry-leading uptime through proactive cloud engineering and robust contractual safeguards.
