Cisco AnyConnect vs Zscaler: What are the differences?

Introduction

In this article, we will compare Cisco AnyConnect and Zscaler, two popular secure networking solutions. We will analyze their key differences and understand how they are distinct from each other.

1. Endpoint Connectivity: Cisco AnyConnect is a client-based VPN solution that enables secure remote access to network resources using various authentication methods. It allows users to connect to a corporate network through a VPN tunnel, providing secure and encrypted communication. On the other hand, Zscaler is a cloud-based security platform that leverages the concept of secure web gateways (SWGs). It provides secure access to the internet for remote users without requiring a traditional VPN, ensuring malware protection, data loss prevention, and compliance.

2. Deployment: Cisco AnyConnect requires the installation of a client application on the endpoint device. This application establishes a secure connection with the corporate network. In contrast, Zscaler is a cloud-native service that does not require any client installation. Users can access the internet securely through the Zscaler platform using their web browsers without the need for additional software.

3. Security Features: Cisco AnyConnect offers features like VPN encryption, multi-factor authentication, and endpoint security policies. It provides granular control over network access based on user identity and device posture. Zscaler, on the other hand, offers advanced web security features like secure web gateways, URL filtering, malware protection, and advanced threat protection. It inspects all internet traffic, enforcing security policies regardless of the user's location.

4. Traffic Routing: With Cisco AnyConnect, all internet traffic from the user's device is routed through the corporate network, ensuring that security policies and monitoring are applied. Zscaler routes internet traffic through its global network of data centers, allowing for greater scalability and reduced latency. It also offers local breakout capabilities, enabling direct internet access for specific traffic without backhauling it to the corporate network.

5. Scalability: Cisco AnyConnect requires the deployment of VPN concentrators and infrastructure on the corporate network to handle remote connections. This might limit its scalability, especially for large organizations with numerous remote users. Zscaler, being a cloud-based service, offers excellent scalability, as it can handle a high volume of remote connections by leveraging its distributed infrastructure.

6. Management and Reporting: Cisco AnyConnect provides administrators with comprehensive management and reporting capabilities to monitor and control users' VPN access and security policies. Zscaler offers a unified management console with real-time visibility into user internet activity, security events, and policy enforcement. It provides detailed reporting and analytics to help administrators gain insights into their network's security posture.

In summary, Cisco AnyConnect and Zscaler differ in terms of endpoint connectivity, deployment model, security features, traffic routing, scalability, and management capabilities. These differences enable organizations to choose a solution that best aligns with their specific requirements and security needs.
