Imunify360 is a comprehensive security suite designed for Linux web servers. It's an all-in-one solution that integrates various security layers to protect servers from a wide range of threats. Here's a breakdown of what Imunify360 is and its key aspects:

Core Features and Functionality:

Imunify360 demploys a multi-layered approach to security, combining several powerful features that work together:

• Real-time Malware Scanning and Cleanup: Scans files in real-time as they are created or modified, as well as performing scheduled and on-demand scans. It can automatically clean up infected files, including removing malicious code from databases.
• Web Application Firewall (WAF): Analyzes and filters incoming web traffic, blocking malicious requests and attacks like SQL injection, XSS, and RFI. It uses cloud heuristics and AI to detect new threats.
• Intrusion Detection and Prevention System (IDPS): Monitors server traffic and identifies suspicious activity, blocking potential cyberattacks.
• Proactive Defense: This unique technology analyzes PHP scripts' behavior in real-time to identify and block malicious execution flows, even for zero-day exploits. It can operate in "Log Only" mode or "Kill Mode" to automatically stop malicious scripts.
• Firewall: An advanced firewall that uses machine learning and a global IP reputation database to block incoming traffic from known malicious sources and monitor for suspicious activity. It includes features like a Grey List (for temporary blocking and CAPTCHA challenges), and blacklisting/whitelisting of IPs and countries.
• Patch Management (KernelCare): Keeps the server kernel secure with automatic, rebootless updates, ensuring protection against known vulnerabilities. (Note: KernelCare is often included or integrated with Imunify360).
• Domain Reputation: Monitors the reputation of your domains and actively blocks connections from known malicious IP addresses, preventing blacklisting by search engines and antivirus services.
• PHP Security Layer: Provides additional security for PHP-based applications.
• Anti-Bot Protection: Effectively blocks bad bots, including those involved in brute-force attacks, vulnerability scanning, and spamming.
• Centralized Management: Offers a user-friendly dashboard within popular control panels (like cPanel, Plesk, DirectAdmin) for easy management and monitoring of security events. It also provides a command-line interface (CLI) for automation.
• Incident Reporting and Notifications: Provides detailed reports on security incidents and offers customizable email notifications.
• Integration with Other Tools: Can integrate with other security tools like CSF/LFD and backup solutions.

Benefits of Using Imunify360:

• Comprehensive Protection: Offers a wide range of security features in a single, integrated solution.
• Automation: Automates many security tasks, reducing the need for manual intervention.
• Real-time Defense: Protects against threats as they emerge, minimizing the window of vulnerability.
• Reduced Server Load: By blocking malicious traffic, it can help reduce server resource usage.
• Lower False Positive Rate: Designed to accurately identify threats and minimize disruptions to legitimate traffic.
• Easy Management: The intuitive interface within hosting control panels simplifies security management.
• Proactive Threat Detection: The Proactive Defense feature can identify and block new, unknown threats.
• Improved Server Stability and Reputation: By preventing attacks and malware infections, it helps maintain server stability and avoid blacklisting.

Integration:

Imunify360 seamlessly integrates with popular Linux-based web hosting control panels, including:

• cPanel & WHM
• Plesk
• DirectAdmin
• ISPmanager
• Webuzo
• It also offers a standalone installation option.

Licensing and Pricing:

Imunify360 licensing is typically based on the number of hosting accounts (users/subscriptions) on a server. They offer various pricing tiers, including options for:

• Single User: For servers with one hosting account.
• Up to 30 Users: For servers with up to 30 hosting accounts.
• Up to 250 Users: For servers with up to 250 hosting accounts.
• Unlimited Users: For servers with an unlimited number of hosting accounts.
• Bulk Pricing: Available for service providers with 5 or more servers.

There's also ImunifyAV+, a premium version of their free ImunifyAV, which includes malware cleanup and reputation management features at a lower price point than the full Imunify360 suite.

You can typically purchase licenses directly through the CloudLinux Network (CLN) website or through your hosting provider. Free trials are often available.

In summary, Imunify360 is a robust and comprehensive security solution for Linux web servers, offering a wide array of features to protect against various cyber threats and simplify server security management.
