Tom Xsilver, thank you very much for the information, I wrote in Portuguese in order to find Brazilians in the community, because my English is weak, I am using Goolge Translator I hope I can understand.
In the photo you sent it shows that the version is at 7.2 but the one that serves my box 30E is 6.2.12, from the next version to 7.2 is no longer supported that my box will be discontinued?
Another question would be how much support dates, end of the engineering support date would be if necessary they release any release data? And the end of the support date would be if I have a problem I need to have the version within its expiration date to be 'answered'?
About your comment, 'about reason to perform an old version,' I don't know either, that's what I will try to find out, I believe it is the lack of an acting plan. Because as improvement of our safety we hired a company to manage firewall, but was following some news (https://boletimsec.com.br/falha-crítica-explored-e-fornece-accessa-a-vpns-da- Fortinet/) that came to me as a warning, is the firewall security company keeping the appropriate updates of the equipment up to date? From what I observed for the available version of update, no!
Thus with your guidelines I will be able to maintain the verification of this equipment whether or not it is updated. Thank you very much.
