What is Zscaler? A quick overview
- Zscaler is a cloud security platform built around two primary products:
- Zscaler Internet Access ZIA: A secure internet gateway that routes user traffic through the Zscaler cloud for inspection, threat prevention, and policy enforcement.
- Zscaler Private Access ZPA: A zero-trust, software-defined access solution that connects users to internal applications without exposing the network.
- How it works: Instead of routing all traffic to a corporate VPN concentrator, traffic is redirected to the cloud proxy via lightweight agents or firewall policies. Zscaler inspects traffic for threats, enforces access policies, and then forwards clean traffic to its destination.
- Target users: Enterprises and organizations needing scalable, cloud-first security and zero-trust access for remote workers and distributed teams.
Key differences: Zscaler vs traditional VPNs
- Traffic flow
- VPN: Routes traffic from the user to a VPN gateway, often back to the corporate network. All traffic may pass through a single point, which can become a bottleneck.
- Zscaler: Uses cloud-based proxies that inspect traffic at the edge. Traffic is routed to the closest Zscaler data center for inspection, then sent to the destination.
- Security model
- VPN: Secures connectivity but often lacks granular, identity-based access controls and inline threat inspection by default.
- Zscaler: Strong emphasis on zero-trust access, identity-based policies, inline threat inspection, data security, and cloud-delivered protection across apps and web traffic.
- Deployment and scalability
- VPN: Requires on-premises hardware or dedicated cloud appliances and can be complex to scale for many users.
- Zscaler: Cloud-native, designed to scale with your organization without backhauling all traffic to a central site.
- Visibility and policy enforcement
- VPN: Focused on connectivity; policy enforcement can be limited to the VPN endpoint.
- Zscaler: Centralizes policy enforcement for application access, internet use, and data protection, with granular controls.
- Performance considerations
- VPN: Potential latency due to backhauling traffic and VPN overhead.
- Zscaler: Latency depends on geo-proximity to Zscaler data centers and policy configuration; many customers report good performance due to regional data centers and optimized routing, but it varies by environment.
Core components explained
- ZIA Zscaler Internet Access
- Purpose: Secure all internet-bound traffic web, SaaS apps, destinations outside the corporate network.
- Features: Secure web gateway, malware protection, advanced threat protection, TLS inspection, data loss prevention DLP, and cloud sandboxing.
