What are the primary components of Zscaler’s security stack?

The primary components of Zscaler’s security stack include Zscaler Internet Access (ZIA), Zscaler Private Access (ZPA), and security policies. ZIA provides secure internet access to users regardless of their location, ensuring that all web traffic is inspected and filtered for threats and compliance. On the other hand, ZPA delivers secure access to internal applications without exposing them to the public internet. This separation of secure internet access and private application access is fundamental to Zscaler's approach to modern security.

Additionally, security policies are crucial as they define how traffic is managed and what controls are applied. They ensure that the organization’s specific security requirements are met, allowing for a tailored security posture that aligns with business needs. Together, these components form a comprehensive security architecture that effectively protects users and applications in today’s cloud-first environments.

The other options either lack essential components of Zscaler's offerings or include elements that do not belong to the Zscaler security stack, such as traditional VPNs or on-premises hardware, which do not align with Zscaler's cloud-centric architecture.
