What's new in PC Tools Firewall Plus 3.0
Better protection against network intruders
New smart Application Rules
PC Tools Firewall Plus now incorporates a set of new smart application rules, designed to make it simpler and easier for you to continue working with minimal interference from your Firewall.
Technically, using the Application Rules within PC Tools Firewall Plus, you can create a heuristic set of rules that control how applications are allowed to connect to the Internet/network and their permissions on your PC. If an application attempts to connect to the Internet/network and there are no corresponding rules, Firewall Plus will allow you to choose how the application should behave.
Stealth Mode protection
Firewall Plus provides you with extra protection via its Stealth Mode feature which enables your system to appear invisible to other computers in the network. When in Stealth Mode, your computer is able to make connections to other computers in the network, but Firewall Plus will prevent other computers from connecting with yours.
Data validation using SPI – stateful packet inspection
Firewall Plus offers extra protection by validating all attempts to access your computer when connected to the internet. No data is permitted to transfer unless if has first been validated by Firewall Plus.
Firewall Plus validates data using SPI – stateful packet inspection – in which it performs a protocol handshake and if successful allows data transfer, otherwise all traffic is blocked - ensuring no unauthorised data is transferred onto your computer.
Application protection
Firewall Plus offers additional application protection by guarding all the applications on your PC from unauthorized access. Enabling this option will shield applications on your system from other applications attempting to take control of them and potentially use them for malicious purposes.
Easier to use with new normal and expert modes
Firewall Plus now caters for two levels of users:
- Normal User Mode offers a simplified interface for basic users to protect their computers when connected to the Internet or any other network. All you need to do is to choose which applications are allowed access to the Internet/network.
- Expert User Mode provides a highly configurable interface for advanced expert users to allow greater control over how your computer and applications connect and interact with the Internet/network. Expert user mode gives you additional options to create custom rules for applications and to control traffic at port-level. Firewall Plus alerts in expert mode are also more detailed to facilitate a greater understanding of the connections made by the applications.
