Enabling Secure Access

The Zscaler Client Connector enables secure remote access by being an integral part of the Zero Trust Exchange. Specifically, it connects to the Zscaler cloud to facilitate user-to-application access based on fine-grained policies.

Without the Client Connector, remote users would need to connect via VPNs and backhaul traffic to centralized gateways for security checks. This introduces latency, connectivity issues, and chokes gateways.

Instead, the Client Connector sets up a persistent SSL connection with the Zscaler cloud. Here is how it works:

  1. The Connector validates device posture and user identity before activating a secure tunnel.
  2. With the tunnel active, access policies stored in the cloud then allow/deny access to specific private applications.
  3. The Zscaler cloud brokers authorized connections between users and applications without traffic needing to go on-premises.

So the Client Connector enables device-to-cloud and cloud-to-application security with integrated access controls. This removes the need for hairpinning traffic and delivers better user experience.

Some key capabilities facilitated by the Client Connector for access include:

  • Direct-to-cloud access: Connector sets up secure tunnel to Zscaler cloud, not the VPN gateway
  • App-specific access: Granular policies allow/deny access per application
  • Real-time analytics: Continuous monitoring of user, device, and app activity

By removing traditional network security constraints, the Client Connector simplifies secure application access for a distributed workforce.

Key Features

The Zscaler Client Connector comes packed with advanced features to enable secure application access while providing admins granular control and real-time visibility.

Access Control Policies

The Client Connector uses identity and context to evaluate access policies for applications managed through Zscaler Internet Access (ZIA) and Zscaler Private Access (ZPA).

Based on rules defined in ZIA or ZPA, it controls which users can access which applications and resources. These access policies offer:

  • User-based rules: Allow/deny resource access based on user identity.
  • Group-based rules: Apply blanket policies across groups like contractors, partners etc.
  • Context-based rules: Check device posture, location, IP reputation before allowing access.

By distributing access policies globally in the cloud, authorization decisions happen instantly at access time.

Real-time Logging and Monitoring

The Zscaler Client Connector provides continuous monitoring and logging of user activity for security and audit purposes.

Its logs offer rich details covering:

  • Users, groups, devices, and locations accessing applications
  • Data transfers and network connections between entities
  • Policy changes, errors etc.

These logs feed into monitoring dashboards and security analytics systems like SIEMs. So admins get full visibility in one place.

Inbuilt Security Controls

As software-defined secure access, the Client Connector has cloud-delivered security controls built-in, including:

  • SSL inspection: Decrypts traffic to detect threats
  • Advanced threat protection: Blocks zero-day malware using AI/ML
  • DNS filtering: Restricts access to malicious domains
  • Data loss prevention: Stops sensitive data exfiltration

These overlay security services maximize protection without backhauling traffic.

Integration with ZIA and ZPA

The Client Connector seamlessly integrates with Zscaler Internet Access (ZIA) and Zscaler Private Access (ZPA) to enable secure connectivity.

While ZIA protects external internet traffic, ZPA secures private application access. The Connector activates policies from both to allow authorized access.

This unified approach simplifies management while closing security gaps across different access channels.


By transforming secure access, the Zscaler Client Connector provides these key benefits:

Improved Security Posture

The Client Connector strengthens the security posture for organizations with remote employees in these ways:

  • Enforces identity-based application access
  • Checks device health before granting access
  • Encrypts traffic end-to-end
  • Blocks threats in real-time
  • Gives admins full visibility and control

Together, these capabilities minimize vulnerabilities while protecting apps and data.

Reduced Risk from Attacks

Software-defined connectivity via the Connector reduces the risk surface by removing traditional VPN infrastructure.

Without complex gateways in the DMZ, there is no local attack vector that can be exploited to target resources on the private network. This shrinks risk.

Higher User Productivity

The Client Connector delivers fast, seamless, and reliable application access which translates into:

  • Fewer connectivity disruptions that hamper productivity
  • No complex VPN setup slowing users down
  • Consistent experience regardless of user location

By reducing friction, it enables employees to be more engaged and productive.

Simplified IT Management

With the Connector, IT teams no longer waste cycles troubleshooting VPN infrastructure or scaling gateways for demand spikes.

Instead, centralized access policies delivered from the cloud simplify management while enhancing agility. One consolidated dashboard provides full visibility too.

Lower Networking Costs

Software-defined connectivity powered by the Client Connector reduces network bandwidth costs associated with backhauling traffic to centralized gateways.

Direct-to-cloud proxying is 65% more efficient compared to VPN concentrators. This adds up to significant WAN savings.
