Viruses and spam scanning of emails

Frabre

I use a USG60W and USG110. I want scan emails for viruses and spam. The emails must be transmitted with an SSL connection (port 995 / port 465) (GDPR). How is this problem solved?

Hi @Frabre,

Antispam works on SMTP and POP3, it cannot scan SSL/TLS connection.

Regarding to AntiVirus, it can scan smtps and pop3s. However, it need to install certificate on client and enable SSL inspection on USG since the SSL/TLS encrypts the content that is transmitted. 

With the SSL inspection,  Inspection transparently unencrypts and re-encrypts traffic to allow AV inspect the content of SSL-encrypted connections.

So is antispam a waste of money if i want stick the GDPR?

@Frabre
indeed with you - but Zyxel has no "UTM Ligth" packaes without AV/Spam scan in programm.
And the option from the ZyXEL sales to say "buy each one you need" is not realy a solution and is more expensive ;(

Unfortunately we are also purchasing the bundle licence each year although not using the spam and AV detection for e-mails.

But SSL inspection is not a solution for us since this would interrupt the end-to-end SSL encryption chain.

Our e-mail traffic will be checked once with our ISP and twice at the local user machine where the e-mail client program is running. This should be sufficient.

I'm with Christian, bundles without spam and AV should be offered by Zyxel as well.
