What is Zscaler exactly?
Zscaler is a cloud-native security platform delivered as a service. It routes your traffic through its global cloud proxies to enforce security policies, inspect traffic for threats, and protect data. Rather than building a tunnel from your device to a company network as a traditional VPN does, Zscaler focuses on identity-based access, continuous threat prevention, and zero-trust principles. In many setups, it replaces or augments VPNs by removing the need for backhauls to a central data center and instead applying protection at the edge of the cloud.
How Zscaler works in practice
- Identity and access control: You sign in, and access policies are applied based on user identity, device posture, and context location, risk signals, etc..
- Traffic inspection: Web traffic and non-web traffic pass through Zscaler’s cloud, where it’s scanned for malware, data loss prevention DLP violations, and unsafe content.
- Secure access cannot be easily bypassed: Rather than opening a tunnel to the corporate network, Zscaler enforces policies on a per-application or per-resource basis.
- Cloud-first architecture: Because it’s built for the cloud, you don’t rely on a single VPN concentrator or a fixed campus boundary. This helps with remote work and multi-cloud environments.
- Zero Trust Network Access ZTNA integration: Zscaler often acts as the enforcement point for zero-trust access, granting least-privilege access to apps and services.
Zscaler vs. traditional VPN: the core differences
- Access model
- Traditional VPN: Creates a tunnel from user device to the corporate network, giving broad access to internal resources often all-or-nothing.
- Zscaler: Grants access to specific apps or services with identity-based policies, reducing exposure and lateral movement.
- Security posture
- VPNs: Focus on encrypting traffic between device and network; security is often centered around the VPN gateway.
- Zscaler: Adds continuous inspection, threat prevention, DLP, malware scanning, and policy enforcement at the edge of the cloud.
- Deployment and scalability
- VPN: Requires on-prem hardware or virtual appliances; scaling large remote access can become complex and costly.
- Zscaler: Cloud-native, scales with demand, and is easier to update with new security policies without touching endpoints.
- Visibility and control
- VPN: Limited visibility into app-level usage; traffic is often treated as a single stream.
- Zscaler: Per-application visibility, granular policy controls, and detailed telemetry for security analytics.
- Performance implications
- VPN: Performance depends on gateway capacity and backhaul; sometimes users experience latency if traffic is forced through distant data centers.
- Zscaler: Often provides lower latency by routing to the nearest cloud data center and optimizing paths, but actual performance varies by location and policy complexity.
- Data handling and DLP
- VPN: Data protection features rely on endpoint security and network security stacks.
- Zscaler: Strong focus on DLP and data protection at the edge, useful for regulated data and compliance requirements.
When to use Zscaler instead of a VPN
- You’re embracing zero-trust: If your organization wants least-privilege access and continuous verification, Zscaler fits nicely.
- You need app-level access: If employees need to reach specific SaaS apps or internal apps without exposing the entire network, Zscaler’s model is ideal.
- You’re moving to the cloud: For multi-cloud or cloud-first setups, a cloud-native security stack reduces on-prem dependencies.
- You want enhanced threat protection: Built-in malware scanning, URL filtering, and DLP are strong additions beyond a basic VPN.
- You’re aiming for better visibility: If you need granular telemetry on who is accessing what and from where, Zscaler provides richer analytics.
When to keep a traditional VPN
- You require full network access: If your workflows depend on line-of-business applications that require broad access to internal networks, a VPN might be simpler.
- Legacy application compatibility: Some old apps don’t play well with zero-trust access or cloud-based proxies.
- Simple remote access needs: Small teams with straightforward needs might prefer a straightforward VPN setup for ease of use.
- Strict regulatory or audit requirements: Some environments still mandate VPN-style audit trails; verify your compliance needs.
Performance and reliability considerations
- Global coverage: Zscaler has a broad global network of data centers, which helps reduce latency by routing traffic to nearby points of presence.
- Policy complexity: The more granular your policies per-app, per-user, per-device, the more processing may occur at the edge. This can impact latency if not properly tuned.
- Offline or offline-like scenarios: If users have limited connectivity, VPNs can sometimes provide more predictable connectivity, whereas cloud-based proxies rely on stable internet access.
- Bandwidth and inspection: Deep packet inspection and DLP can add overhead; a careful balance between security and performance is key.
- Redundancy and failover: Cloud-native platforms typically offer robust redundancy, but you should verify your SLA and regional coverage.
Security and policy features you should know
- Zero trust principles: Verify every request, never trust by default, and enforce least privilege.
- Multi-factor authentication MFA: Essential for identity verification before granting access.
- Device posture checks: Ensure devices meet security requirements antivirus, up-to-date patches, encryption before granting access.
- Data loss prevention DLP: Prevent sensitive data from leaving the organization.
- Threat prevention: Malware scanning, URL filtering, and botnet protection to reduce exposure.
- SSL inspection: Some deployments decrypt and inspect encrypted traffic; be mindful of privacy and performance implications.
- Access control to apps: Granular, identity-based access to SaaS apps and internal apps.
Deployment models: how organizations roll it out
- Forward proxy model: Traffic is redirected through Zscaler proxies for inspection, with policy enforcement at the edge.
- ZTNA-based access: Users access specific apps with policy enforcement, rather than broad network access.
- Browser isolation and VPN replacement: For web traffic, Zscaler can function as a secure gateway, reducing direct exposure to the internet.
- Endpoint adapters: Optional agents on endpoints that can provide posture checks and enforce device compliance before granting access.
- Cloud-first philosophy: Ideal for organizations already embracing cloud services and SaaS apps.
