Colasoft Announces Release of Capsa Network Analyzer v9.2

January 19, 2017 – Colasoft, a leading provider of innovative and affordable network analysis solutions, today announced the availability of Colasoft Capsa Network Analyzer v9.2, a real-time portable network analyzer for wired and wireless network monitoring, bandwidth analysis, and protocol decoding.

Application analysis counts a lot in securing enterprise network. Capsa v9.2 brings an application analysis function. More than 1,800 built-in applications are provided, including the popular applications as Amazon, Email, Facebook, Google, Web, Youtube, etc. Besides the built-in applications, users can customize applications for private network services. Custom applications can be defined based on IP address, port number, protocol, packet pattern, and combinations thereof. With application analysis function, network administrators will have a better understanding and control of network traffic, which makes network monitoring and troubleshooting easier.

HTTPS is a protocol for secure communication over network, which is widely used on the Internet. With this safer protocol, it becomes more complicated to analyze the traffic today. And considering this circumstance, Capsa v9.2 adds HTTPS decryption capability to enable users to decrypt the HTTPS message with the right configuration of key file.

Moreover, Capsa v9.2 adds more than 200 new protocols, which enhance protocol recognition capability. And users could select a certain medium type to capture or replay the packets. Also, a Dup ACK mark and a Retransmission mark are added to the packet decoding window to facilitate protocol decoding.

"Colasoft R&D department involves optimizing Capsa to satisfy users’ needs of network analysis.” said Eddie Gao, CTO at Colasoft, “Also, we add new features to Capsa v9.2 to meet with the increasingly complex network environment, in order to provide a functional tool for our users.”
