How to Configure CyBlock Proxy for Complete Enterprise Security

Step-by-Step Guide to Deploying CyBlock Proxy in Your Network

Deploying a dedicated web proxy is a critical step in securing corporate networks and managing internet bandwidth. CyBlock Proxy provides robust web filtering, traffic monitoring, and policy enforcement. This guide delivers a direct, technical walkthrough to successfully integrate CyBlock Proxy into your existing network infrastructure. Prerequisites and Planning

Before beginning the installation, ensure your environment meets the necessary system and architectural requirements.

Dedicated Server: Prepare a physical or virtual machine running a supported Linux distribution (CentOS/RHEL or Ubuntu Server) or Windows Server.

Network Interface Cards (NICs): A minimum of one NIC is required for simple proxy setups. Two NICs are recommended for inline or bridge deployments.

Static IP Address: Assign a permanent, static IP address to the CyBlock gateway.

Firewall Rules: Configure your network perimeter firewall to allow outbound traffic from the CyBlock IP on ports 80 (HTTP) and 443 (HTTPS). Step 1: Download and Installation

Obtain the official installer package from the Wavecrest computing portal.

Download the Installer: Log into your account and download the CyBlock Proxy installation package matching your target Operating System. Execute the Package:

For Linux: Open a terminal, make the installer executable (chmod +x cyblock_installer.run), and run it with root privileges (sudo ./cyblock_installer.run).

For Windows: Right-click the .exe file and select Run as Administrator.

Follow the Wizard: Accept the license agreement, choose the installation directory, and wait for the core services to extract. Step 2: Initial Configuration and License Activation

Once the installation finishes, you must initialize the software via its web-based management console.

Access the Console: Open a web browser on a device within the same network. Navigate to http://:8080 (or the custom port specified during installation).

Set Credentials: Create a secure administrative username and password during your first login.

Activate License: Navigate to the Administration tab, select Licensing, and input your product license key to activate full filtering capabilities. Step 3: Network Integration

Choose the deployment method that best fits your network topology. The two most common methods are Explicit Proxy and Transparent Proxy. Option A: Explicit Proxy Mode

In this mode, client browsers are explicitly told to send traffic to the proxy.

Configuration: Inside the CyBlock console, go to Network Settings and define the listening proxy port (default is usually 8080 or 3128).

Client Deployment: Distribute the proxy IP and port to end-user devices using a Group Policy Object (GPO) or a Proxy Auto-Config (PAC) file. Option B: Transparent Proxy Mode

This mode intercepts traffic automatically without requiring client-side configurations.

Configuration: Enable transparent interception in the CyBlock settings.

Routing: Configure your core network switch or router to use Policy-Based Routing (PBR) or WCCP, forwarding all outbound port ⁄₄₄₃ traffic directly to the CyBlock IP address.

Step 4: Configuring SSL Inspection (Optional but Recommended)

Modern web traffic is almost entirely encrypted via HTTPS. To inspect this traffic for threats and categorize pages accurately, you must enable SSL Decryption.

Generate Certificate: Navigate to HTTPS Inspection in the console and generate a unique Root Certificate Authority (CA) certificate.

Export the Certificate: Download the Root CA certificate from the CyBlock interface.

Deploy to Clients: Use Active Directory GPO to install this certificate into the “Trusted Root Certification Authorities” store on all network endpoints. This prevents users from seeing security warnings. Step 5: Establishing Security Policies and Filtering

With traffic flowing through the proxy, define your organization’s acceptable use policies.

Category Filtering: Go to Policy Management -> Web Filtering. Block or allow specific web categories such as gambling, social media, or known malware domains.

User Authentication: Link CyBlock to your Active Directory or LDAP server via the Directory Services menu. This allows you to apply different filtering rules based on user roles or departments.

Testing: Attempt to visit a restricted website from a client machine to confirm that the CyBlock blocking page appears correctly. Monitoring and Maintenance

After deployment, review the dashboard logs daily to monitor bandwidth consumption, top web destinations, and blocked threat vectors. Schedule regular backups of your configuration files and keep the deployment updated with the latest URL category databases provided by Wavecrest.
