A practical guide to understanding the Cato Client, its purpose, and how to use it for secure remote access.
Understanding the Cato Client and its role in modern connectivity
The Cato Client is a lightweight software agent designed to extend Cato’s secure networking and zero-trust access to users wherever they are. It’s used by organizations to give employees secure access to corporate resources, SaaS apps, cloud services, and the broader internet without relying solely on traditional VPNs. The client runs on devices like Windows, macOS, iOS, and Android, and it works in concert with the Cato Cloud to provide policy-based connectivity and traffic inspection.
What the Cato Client does
- Authenticates users and devices to ensure only authorized personnel access the network.
- Enforces security policies centrally so remote connections adhere to organizational rules.
- Performs traffic inspection to detect and block threats before they reach resources.
- Enables secure access to a mix of destinations: the public internet, SaaS applications, and private cloud resources.
- Supports remote work with a consistent security posture across locations and networks.
Who should consider using the Cato Client Understanding Proxies: What They Are, How They Work, and When to Use Them
- Enterprises seeking a zero-trust approach to remote access
- Teams that require secure, policy-driven access to cloud and on-prem resources
- Organizations needing a unified way to protect users across devices and networks
- Companies moving to remote work models and distributed workforce structures
Getting started with the Cato Client
- Installation steps: The Cato Client can be installed on supported operating systems. The setup process typically includes authenticating the user, enrolling the device, and applying security policies.
- Known platforms: Windows, macOS, iOS, Android. The client is designed to work with Cato Cloud and integrate with an organization’s policy framework.
- App store availability: The Cato Client is available in the Apple App Store for iOS devices and the Google Play Store for Android devices, making it accessible for mobile users. There are also enterprise download portals for desktop clients.
- Preparing to install: Before installing, ensure you have the required credentials, device management approvals, and any organization-specific configuration details (such as policy groups or gateway settings).
How the Cato Client fits into a zero-trust architecture
- Identity and device posture: Access decisions are based on who you are and the security state of your device.
- Secure connectivity across locations: The client ensures that remote traffic is routed through the Cato Cloud with policy enforcement.
- Continuous verification: Rather than granting broad trust, each session is evaluated against current policies and threat intelligence.
Comparing the Cato Client to traditional VPNs
| Feature | Cato Client (zero-trust) | Traditional VPN |
|---|---|---|
| Access model | Identity- and policy-based with continuous evaluation | Perimeter-based, often broad trust after login |
| Traffic inspection | Centralized, with threat prevention and zero-trust controls | Limited inspection, depends on VPN and endpoint security |
| Resource access | Fine-grained access to apps, SaaS, and networks | Often all-or-nothing access to network segments |
| Device posture | Checks device state before granting access | Varies; may not enforce continuous posture checks |
| Scalability | Designed for distributed users and cloud resources | Can be harder to scale with many remote users |
Security considerations and best practices
- Keep the Cato Client up to date: Regular updates help ensure you have the latest security features and patches.
- Use strong authentication: Combine usernames with strong credentials and, where supported, multi-factor authentication (MFA).
- Enforce least-privilege access: Configure policies so users only access the resources they need for their role.
- Monitor and audit: Leverage logging and telemetry to detect unusual access patterns and respond quickly.
- Ensure device health requirements: Enforce endpoint posture checks to prevent compromised devices from connecting.
