Often utilized for private or internet-based private networks where preventing unauthorized access is challenging, Privatefirewall is an integrated desktop firewall and multi-layered intrusion prevention program. It provides signature-less protection for one hour against spyware, viruses, hacking techniques, and other intrusions on Windows-based desktops and servers.

Privatefirewall is a rule-based firewall program that monitors not only incoming and outgoing communications to and from the network and user's computers but also processes and logging. Established in 1999, Privatefirewall is a security company.

In the realm of cybersecurity threats such as keyloggers, intruders, trojans, and other invasive threats that can attack the system, Privatefirewall stands as the solution. It is an effective private firewall and host intrusion prevention program, establishing a barrier between the personal computer and the threats present in the online world.

Privatefirewall comprises several distinct layers of protection, including desktop firewall, port manager, URL filtering, process monitoring, application behavior modeling, system behavior modeling, and anomaly detection components. Privatefirewall evaluates WinAPI calls, analyzes a comprehensive list of system variables and sensitive registry keys for security, and provides alerts to administrators about potential malware, attacks, or policy violations.

1. Advanced Packet Filtering: Proprietary packet inspection technology monitors all communications between the computer and the internet. It detects and blocks unauthorized traffic, allowing users to adjust security levels—high, low, or custom—for different internet and local network access.

2. Ultimate Application Control:  A highly configurable application control module enables users to precisely define which applications can access the internet and how they do so.

3. Process Discovery: Prevents viruses, Trojans, worms, and other malware by tracking all trusted processes. It provides alerts when any potentially harmful process attempts to run.

4. System Error Detection: Detects system errors by monitoring core engine variables, such as CPU usage and link index count. It observes normal usage patterns of running applications and generates alerts upon detecting unusual activity.

5. Smart Alerts: Built-in, user-friendly alerts provide detailed information on security events. They offer convenient web search and predefined smart responses for timely and intelligent actions.

6. Stealth Mode: Makes the personal computer invisible when connected to the internet, protecting against potential intruders.

7. Port Tracking and Reporting: Monitors all ports to prevent unauthorized scanning and system probing. Detailed reports on port scanning operations and other intrusion attempts are generated, along with immediate on-screen alerts.

8. Email Error Detection: Mitigates the impact of attacks targeting email clients by tracking the volume and frequency of outgoing emails. Privatefirewall alerts users and prevents unacceptable deviations from regular email activity.

9. Application Control and Firewall Policy Management: Monitors all traffic to and from the user's computer, preventing trusted applications from being hijacked for local file theft or network-accessible file theft.

10. Process Monitor Layer: Adds a crucial defense layer to traditional firewall protection by defining behavior properties at the process level for intrusion techniques and malicious program activities.

11. Internet Access Control: Controls applications' internet access, allowing users to permit or block each application with every use or establish permanent permissions. It can block specific IP addresses or designated websites or allow access to them.

12. Customizable Package Filtering Rules: Specifies application-specific or global package filtering rules applicable to incoming, outgoing, or bidirectional traffic.

13. Advanced Firewall Reports: Displays or generates advanced firewall reports categorized by web, email, or attempts to access the system, spanning hours, days, weeks, or custom time frames.

14. Unparalleled Ease of Use: Privatefirewall provides unmatched ease of use, offering pre-configured security settings that deliver superior protection upon installation. Configuration and setup are fully automatic once the device is unpacked and turned on.

15. One-Click Configuration: Configures with a single click for pre-defined security settings for home, office, and remote profiles, eliminating the complexity of application settings.

16. Seamless Network Communication Detection: Detects network communications seamlessly and automatically assigns rules allowing access within that network.

17. Advanced Configuration Interfaces for Power Users: Advanced users can easily access a variety of customizable configuration interfaces.

18. Full Integration with Windows Security Center: Fully integrated with Windows Security Center for comprehensive security management.

19. Multi-language Support and Identity Protection: Supports multiple languages and provides identity protection, in addition to internet security, bandwidth usage monitoring, multi-server monitoring, and virus detection.

20. Backup, Hard Drive, Advanced Firewall, Two-Way Firewall, Remote Server Monitoring, Webcam, and Microphone Detection: Offers backup capabilities, advanced firewall protection, two-way firewall, remote server monitoring, and detection of webcam and microphone usage.

There are numerous cyber threats such as keyloggers, intruders, Trojans, and other invasive threats that can attack the system. PrivateFirewall is an effective solution, serving as a dedicated firewall and intrusion prevention program to create a barrier between the personal computer and threats present in the online world.
