Free Firewall What is Free Firewall?
Gratis firewall is een professionele firewall met volledige functionaliteit die beschermt tegen de bedreigingen van internet. Beheer elk programma op uw computer met een vergunning of weiger toegang tot internet. Gratis firewall waarschuwt u wanneer applicaties zonder uw medeweten op de achtergrond toegang willen tot internet. In monitoring mode, no software can access the Internet or network without your prior authorization. You have full control over the flow of data out of your system and into.
Protection against threats
External threats
Prevent attackers from gaining access to your computer by exploiting security vulnerabilities. Protect yourself from a remote access and control of your system and access to your personal information.
Internal threats
Protect yourself, your privacy and your personal data, by preventing the intruded malware from access to the Internet. Prevent that viruses and worms spread on the network.
Free firewall with many features
Protection on the Internet
Individually regulate the access to the network and Internet per application. Allow access to the Internet only those programs, you unconditionally trust.
Privacy
Protect your privacy and personal information with FreeFirewall. Prevent web tracking while surfing and collecting telemetry.
Monitoring mode
Trust no one! In monitoring mode, no software can access the Internet or network without your prior authorization. Only applications you trust get Internet access.
Functions overview
Access notification
If a non-regulated program wants to access the Internet, you will receive immediately a notification with which you can permit or block the Internet access.
Regulate internet traffic
Individually regulate the access to the network and Internet per application. Allow access to the Internet only those programs, you unconditionally trust.
Protection against web tracking
Prevent that tracking services on web sites analyze your surfing habits. De firewall voorkomt oproepen naar statistieken en analyseservices op internetpagina's, die het gebruikersgedrag op de achtergrond registreren.
Prevent telemetry
Prevent the transmission of telemetry data from software vendors to their servers. The firewall blocks all background transmissions of telemetry data of the Windows operating system to the server on the Internet.
Detect viruses
Anti-virus software only protects against known threats. New viruses are only taken after weeks into the anti-virus database. In the meantime, a virus can wreak havoc. With Free Firewall you determine which program transfer data in the background and prevent them. So your personal information doesn't fall into foreign hands.
Block botnets
Botnets consist of a lot of computers that are running a malware in the background and can be remotely exploited for attacks. Free Firewall notifies you of transmissions in the background, which you can quickly block.
Cooperative mode
Unlike many other Firewalls, Free Firewall can be operated with any other firewall in parallel. Also with Windows Firewall. So enjoy a higher level of protection and combine different functions to their added value and without extra cost.
Rule concept
Rules are assignments of permissions to a program. This allows you to specify which websites a program may and may not access.
Structure of rules
Rules consist of an address or domain, a port and a permission.
Rules with domains
Rules can also contain domain names instead of addresses.
Example : www.example.com
Address ranges
Rules can consist of address ranges or be defined with prefixes.
Example : 127.180.0.1/16
Zone concept
Zones are groups and can be assigned to programs to grant common authorization for multiple programs.
Zone rules
Zones can contain a lot of rules. All programs assigned to this zone inherit the permissions of the zone.
Export and import
Export program permissions, zones, rules, and settings from your program. Later you can import them again on the same or different computer.
Filter and sorting
The programs, services and zones can be filtered and sorted by relevance or name.
Web accelerator
Faster surfing on websites, faster loading and saving bandwidth.
Prevent web tracking
Web tracking tracks the surfing behavior of Internet users. FreeFirewall protects against tracking and monitoring of Internet users through cookies and other similar identification techniques.
Event notification
Event notifications appear when processes want to access the Internet. You can then decide if internet access is allowed.
List of all events
The events window lists all Internet access events in a list.
Multilingual
The user interface has been translated into your language, so you can get the full protection. And that for free! Is your language still not under the translated, so help and translate with us!

Hello, I have just installed your "Free Firewall" and really have to say : Good work! Exactly so I imagine a firewall program: not annoying, is not overloaded with features, is clear and has no noticeable impact on performance. - Jan K.
I am very happy with the Firewall. Finally, a simple and self-explanatory handling. - Christian
Big compliment for your Firewall. For the 1.0 Version of a really good throw. There is currently no ordinary standalone firewalls. Free anyway. Thus, it would be great if you just makes further. Thank you and kindly greeting of respect - Harbo
