Cisco Secure Access vs Zscaler Private Access (ZPA) comparison

Cisco Secure Access is a comprehensive Security Service Edge (SSE) solution (a key component of a SASE solution) that addresses the complexities of securing a hybrid enterprise. Cloud-delivered and grounded in zero trust, it delivers a unique blend of user simplicity and IT efficiency for frictionless, secure access to all applications—SaaS (with gen AI), private apps, and the internet—regardless of user location or device. Secure Access protects users, data, and devices against relentless, sophisticated, and constantly evolving threats including AI-driven attacks and identity breaches.

Provides all core SSE components (ZTNA, SWG, CASB, and FWaaS) plus extended capabilities.

• Includes VPN-as-a-Service (VPNaaS), data loss prevention (DLP), AI Assistant, visibility/control/guardrails for generative AI use, digital experience monitoring (DEM), reserved IP, remote browser isolation (RBI), DNS-layer security, flexible security enforcement (in cloud or on-premises), policy verification, and more.

• Protects users as they seamlessly access resources and apps with no extra steps needed, regardless of protocol, port, or level of customization

• Simplifies IT operations through a single client, single dashboard, single license, and unified policies.

• Lowers risk with least privilege, granular controls backed with unmatched threat intelligence of Cisco Talos.

• Eases interoperability with other products from Cisco and third-party vendors with common administrative controls, data structures, and policy management.

Robust integrations

• Integrates with Cisco Identity Intelligence to protect against the startling increase in identity-based attacks.

• Integrates with many SAML Identity Providers (IDPs) such as AD, Azure AD, Okta, Ping, etc.

• Integrates with Cisco offerings including SD-WAN, Splunk, XDR, Thousand Eyes, third party technologies such as Menlo RBI, Chrome Enterprise Browser, and AppOmni for SSPM.

Zscaler Private Access enhances security by enabling access to specific applications without exposing entire networks. It is designed for scalability and flexibility, making it particularly suitable for cloud transitions and remote work environments.

Zscaler Private Access offers a comprehensive solution for modern security needs by ensuring secure remote application access. This is achieved through its advanced features such as micro-segmentation and AI capabilities. Organizations can integrate ZPA with existing security infrastructure, providing seamless operation during cloud transitions. Users benefit from policy-based access management and dashboards that enhance visibility and control. However, ZPA faces some challenges, including bugs, configuration difficulties with identity providers, and a limited rule customization capacity. Delayed support responses and annual price increases are also concerns that need addressing.

• Micro-segmentation: Restricts application access to improve security.
• AI Capabilities: Enhances operational efficiency through intelligent actions.
• Group Access: Allows secure access management for different user groups.
• Policy-based Access: Ensures control and oversight with customized policies.
• Integration Support: Seamlessly incorporates existing security tools.

• Scalability: Supports growing demands without compromising service.
• Ease of Use: Simplifies operations for remote access and cloud integration.
• Visibility and Control: Comprehensive oversight through dashboards and policy management.
• Operational Flexibility: Allows adjustments to meet user requirements effectively.

Zscaler Private Access is widely adopted across industries transitioning from traditional VPNs to more secure remote access solutions. Companies leverage it for secure network communication, accessing cloud resources like AWS and Azure, and integrating with internal systems. Local, customer, and cloud networks extensively use ZPA for secure internet access and as a modern replacement for older proxy technologies.
