Secure Your Network

A Firewall is one of the most effective security tools available for protecting internal network users from external threats. A firewall resides between two or more networks and controls the traffic between them as well as helps prevent unauthorized access. Firewall products use various techniques for determining what is permitted or denied access to a network.
Packet Filtering - Prevents or allows access based on IP or MAC addresses.
Application / Web Site Filtering - Prevents or allows access based on the application. Websites can be blocked by specifying a website URL address or keywords.
Stateful Packet Inspection (SPI) - Incoming packets must be legitimate responses to requests from internal hosts. Unsolicited packets are blocked unless permitted specifically. SPI can also include the capability to recognize and filter out specific types of attacks such as DoS.
