What is Zscaler? How it works in practice
- Zscaler is a cloud-based security platform that provides secure access to applications and data, no matter where users are located.
- Key components:
- Zscaler Internet Access ZIA: Secure web gateway, SSL inspection, data loss prevention, and more for user traffic going to the internet.
- Zscaler Private Access ZPA: Zero Trust access to internal apps without exposing them publicly.
- Inline security checks: Traffic goes through Zscaler’s cloud security stack for policy enforcement.
- How it’s used:
- Employees connect to the internet and business apps through Zscaler’s cloud, often via lightweight clients or browser-based access.
- Security policies travel with the user, not the device, enabling consistent protection across locations and networks.
- Benefit snapshot:
- Improved visibility and control over user activity
- Reduced risk of data leakage
- Simplified remote access without traditional VPNs
- Real-world example:
- A global company deploys ZIA to secure all internet access and ZPA to give remote workers access to internal apps without creating a broad VPN footprint.
What is a traditional VPN? How it differs from Zscaler
- A VPN Virtual Private Network creates a secure, encrypted tunnel between your device and a VPN server, routing all or selected traffic through that server.
- Common goals:
- Private, encrypted path to the internet or to a corporate network
- Bypass geo-restrictions or censorship
- Remote access to internal resources as if you were on a corporate network
- Core differences vs Zscaler:
- All traffic routing vs policy-driven security: VPNs tunnel traffic to a single point; Zscaler evaluates traffic and enforces security policies in the cloud.
- Perimeter mindset vs Zero Trust: VPNs often imply a trusted internal network; Zscaler follows Zero Trust, assuming no implicit trust.
- Scope of protection: VPN focuses on confidentiality and access; Zscaler adds web filtering, threat prevention, data loss prevention, and app access controls.
- Deployment model: VPNs can be appliance- or software-based and require on-device configuration; Zscaler is cloud-native with lightweight client options and seamless global scalability.
