We had recently migrated our funds from CA to CSS account. It was due to an email notification from Comodo.
Could you please advise how we can now order new HackerGuardian licences?
There is no such option available on https://accounts.comodo.com. The only way we can choose such product is on https://secure.comodo.com, but all our funds have been moved to https://accounts.comodo.com
HackerGuardian should be purchased through https://secure.comodo.com. Funds can be transferred back to CA, I will PM you more information on how to request this.
