This is somehting you configure at setup, there is no default for the appliance (i.e if you don't set one, it's meant to prompt you for one):

Configuring the Symantec Endpoint Protection Security Virtual Appliance installation settings file

Hi Nagaraj,

Could you please explain, what your queries is? Is it a virtual appliance or SEPM installed VM Guest? I am not aware of any virtual appliance of SEP.

I have Downloaded Symantec_Endpoint_Protection_12.1.2_Security_Virtual_Appliance_ML.ova From fileconnect I installed the ova setup in ESXI server and booted now i am getting login screen where do i find the credientials for this appliance as i didnt get the prompt for configuring any username password or IP address. Pleae help me out to configure it.

vCenter Administrator user name and password are required to install the Security Virtual Appliance. If you do not configure the password in this settings file, then the installation prompts you for the password.

It's probably worth noting that the example in the article uses "symantec" as teh password.

I'd recommend you try to rummage out the SVA_InstallSettings.xml file you used during the install.  You must have gone through this in order to correctly link it into the SEPM in the first place, so hopefully you've saved it somewhere.

If you haven't, and the SVA is completely unconfigured, then I'd recommend removing it and recreating the SVA anew (with a recorded set of installation settings and passwords )

got the default usernam and password it working

user name : sav

password  : symantec
