The above statement is your opinion. So far, There has been no official statement by Comodo regarding whether or not Comodo Internet Security (CIS) will continue to be developed and updated. The thread you mention referred to a staff member’s post in the Xcitium forums. @EricCryptid (a moderator here) concluded that the Xcitium post was likely misinterpreted and that CIS is not discontinued (an assessment that I agree with). It is well known that Comodo’s products are not updated often, but that does not mean that they have been discontinued.
Unfortunately, we rarely get any official communication from Comodo, which leads to rampant speculation.
Perhaps @Melih can help resolve this uncertainty. Is Comodo planning to maintain and update CIS in the future?
