Looking for information on Protocol TCP 8443? This page will attempt to provide you with as much port information as possible on TCP Port 8443.
TCP Port 8443 may use a defined protocol to communicate depending on the application. A protocol is a set of formalized rules that explains how data is communicated over a network. Think of it as the language spoken between computers to help them communicate more efficiently.
Protocol HTTP for example defines the format for communication between internet browsers and web sites. Another example is the IMAP protocol that defines the communication between IMAP email servers and clients or finally, the SSL protocol which states the format to use for encrypted communications.

Side note: TCP port 8443 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered on port 8443 in the same order in which they were sent. Guaranteed communication over port 8443 is the key difference between TCP and UDP. UDP port 8443 would not have guaranteed communication in the same way as TCP.
Because protocol TCP port 8443 was flagged as a virus (colored red) does not mean that a virus is using port 8443, but that a Trojan or Virus has used this port in the past to communicate.

WatchGuard SSL devices use 8443.
The port is maily for secure transfer (https) I guess..
It also allows access to a spanish-written (I think) web site that I couldn’t even read. Access was originally blocked by firefox 4 beta 11 and I inadvertently allowed access by clicking the “allow access” button! I do have a question: How can I RE=- BLOCK it!
also used by MNF, Firewall simple Mandrake based
Also used by front end of PLESK
Also used by VMware Guided Consolidation.
Used by InstallShield for registering licenses
Also used by Symantec Endpoint Protection Manager (java interface)
