If you’re struggling to choose between Bluecoat Proxy SSL and Proxy SSL, here is a comprehensive guide that will help you weigh out the features of both. This way, you can take an informed decision using the proxy server that best meets your requirements. 

What is a Bluecoat Proxy Server? 

Bluecoat ProxySG, now known as Symantec ProxySG after being acquired by Symantec (which was later acquired by Broadcom), is a type of proxy server that is primarily used for web security and optimization. It is a hardware appliance or software solution that acts as an intermediary between client devices (such as computers, smartphones, or tablets) and web servers. Bluecoat ProxySG is commonly used in enterprise environments to enhance network security, improve performance, and enable better control over internet traffic.

Key features include content filtering, caching, optimizing WAN, SSL encryption, mitigating security threats, logging and reporting, proxy services, access control, identifying users, and more. 

How Does a Bluecoat Proxy Server Work? 

A Bluecoat Proxy server, also known as ProxySG, is a sophisticated intermediary that plays a pivotal role in enhancing network security, performance, and control. This hardware appliance or software solution operates by intercepting and managing internet traffic between client devices and web servers. Here’s how it works:

Interception of Web Requests

When a client device, such as a computer, attempts to access a website, the request is first routed to the Bluecoat Proxy server rather than directly to the web server. This enables the ProxySG to inspect and control the traffic.

Content Filtering and Policies

One of the core functions of a Bluecoat Proxy server is content filtering. It assesses web requests against predefined policies. Depending on the configured rules, the proxy can either permit or block access to specific websites or categories of websites. This helps organizations enforce security and acceptable use policies.

Caching for Improved Performance

ProxySG can cache frequently requested web content. When a client requests a previously accessed resource, the proxy can serve the cached content instead of fetching it from the internet, reducing bandwidth consumption and speeding up access times.

SSL/TLS Decryption

If you’re wondering- can Bluecoat Proxy see SSL traffic, here’s the deal- to detect and mitigate security threats hidden in encrypted traffic, the Bluecoat Proxy server can decrypt SSL/TLS-encrypted data streams. It inspects the content for malware or policy violations before re-encrypting and forwarding the data to the client. So, Bluecoat proxy SSL certificate is highly decrypted and authenticated. 

User Authentication and Identification

ProxySG can integrate with authentication systems, enabling the identification of users accessing the internet. This facilitates user-specific policies and monitoring, allowing administrators to tailor internet access based on user profiles.

Bandwidth Management

The proxy offers traffic control and shaping capabilities. Administrators can allocate and prioritize bandwidth for various types of traffic, ensuring critical applications and services receive the necessary resources.

Logging and Reporting

 The Proxy server logs web traffic activities, creating an audit trail. It generates detailed reports on internet usage, bandwidth consumption, and security incidents, aiding in compliance and monitoring efforts.

Features and Benefits of Bluecoat Proxy Server

Here’s a quick sneak peek on the features and benefits of using the Bluecoat proxy server: 

Enhanced Security

ProxySG helps organizations protect against web-based threats, including malware, phishing, and data breaches, by enforcing content filtering policies and inspecting encrypted traffic.

Improved Performance

Caching and WAN optimization features reduce latency and speed up access to web content, leading to a better user experience and optimized network performance.

Network Control

Administrators have granular control over internet usage, user access, and bandwidth allocation, allowing for the implementation of tailored policies and compliance enforcement.

User Identification and Accountability

The ability to identify users and monitor their internet activity ensures accountability and helps enforce user-specific policies.

Bandwidth Management

Organizations can allocate and prioritize bandwidth to critical applications and services, ensuring efficient resource utilization.

Bluecoat Proxy server vs SSL proxy

Bluecoat Proxy server and SSL proxy serve different purposes in the realm of network security and web traffic management, but they can also work in conjunction to enhance security and control. Let’s compare the two:

Bluecoat Proxy Server

A Bluecoat Proxy server, specifically ProxySG, is a multifaceted proxy server that serves as an intermediary between client devices and web servers. Its primary function is to intercept and manage internet traffic, providing features like content filtering, caching, SSL/TLS inspection, user authentication, bandwidth control, and more.

ProxySG is commonly used in enterprise environments to enhance network security, improve performance, and enforce web access policies. It helps protect against web-based threats, optimize bandwidth, and control internet usage within an organization.

ProxySG can inspect both encrypted and unencrypted traffic, making it a versatile solution for identifying and mitigating security threats.

SSL Proxy

An SSL proxy, also known as an SSL/TLS proxy or SSL intercept proxy, specifically focuses on the inspection and management of encrypted SSL/TLS traffic. It is designed to decrypt, inspect, and re-encrypt SSL/TLS-encrypted data flows.

SSL proxies are typically used when there’s a need to inspect the contents of encrypted traffic to detect and prevent threats. They are often deployed to ensure that malware or malicious content is not concealed within encrypted communication.

SSL proxies specifically target encrypted traffic, allowing for the inspection of SSL/TLS-encrypted data streams. This is crucial for identifying and mitigating threats hidden within encrypted communication.


Bluecoat Proxy servers, such as ProxySG, have a broader scope and serve as comprehensive solutions for web security, optimization, and traffic control. They handle a wide range of web traffic management functions.

SSL proxies have a more specific role and specialize in SSL/TLS traffic inspection. They are crucial for ensuring the security of encrypted communications.

In practice, organizations may use both types of proxies in tandem. An SSL proxy can work in conjunction with a Bluecoat Proxy server to provide comprehensive security. The Bluecoat Proxy may handle content filtering, caching, and other functions, while the SSL proxy focuses on encrypted traffic inspection.

The choice between a Bluecoat Proxy server and an SSL proxy depends on an organization’s specific needs. In many cases, they complement each other to provide a well-rounded approach to network security and control.

Bottom Line

Bluecoat Proxy SSL servers offer a comprehensive set of features that provide enhanced security, performance optimization, and control over internet traffic. These benefits are crucial for maintaining a secure and efficient network environment in enterprise settings.
