Do you know ...

Port Explorer is an advanced state-of-the-art lightweight socket analysis and exploration utility designed for both novice and advanced users alike. Although still a relatively new program, DiamondCS Port Explorer is quickly becoming accepted as the leading program of its class (port-to-process mapping). Providing unprecedented viewing and control over the sockets on your Microsoft« WindowsÖ system, the data traffic going through it, and the computers that are connected to it, Port Explorer is a completely unique and powerful program that goes where few others can. In this day and age where system security means everything on the Internet, Port Explorer is a program you can't afford to be without.

While some socket analysis programs simply aim to give you a slightly better view of your sockets than the netstat console program, Port Explorer is like no other and takes socket analysis and control to the highest level, giving you many advanced features not available in any other programs. Some of these features include:

• Port-to-process mapping allowing you to easily see which programs are using which ports/sockets.
  
• IP-to-country resolving allowing you to easily see which country an IP address belongs to.
• Hidden server detection allowing you to easily see invisible programs that use sockets - a method that generically detects virtually all known remote access trojans.
  
• Packet-sniffing allowing you to spy on, record and analyse the transmissions sent/received by sockets and processes.
  
• Process termination with advanced Windows SeDebugPrivilege allowing you to terminate any Win32 process.
  
• Socket termination allowing you to close individual sockets without affecting the parent process or other sockets.
  
• Socket send/receive blocking allows you to prevent individual sockets from sending and/or receiving data.
  
• Real-time activity watching
• Traffic volume reporting allows you to see how many bytes and packets have been sent and received by individual sockets.
  
• Socket creation reporting allows you to see when individual sockets were created.
  
• Network utilities built-in allow you to Ping, Resolve, Traceroute, Whois, and view Statistics.
  
• Whois search client with powerful fully-automatic and manual search options rivals standalone Whois clients in performance and results.
  
• Advanced sorting with moveable and sortable columns and tabs allows you to analyse and filter on-screen data quickly and easily.
  
• Internal databases allow you to cross-search ports and services, countries and domain codes.
  
• World map allows you to see the geographic locations of resolved countries.
  
• Multi-language support allows you to switch languages on the fly.
  
• Configurable interface allowing you to give the program the exact look and feel you want.
  
• Comprehensive documentation that is easy to understand allows you to quickly find the answer to virtually every question you'll ever have about Port Explorer.
