The 2020 price list of the communigateis for 50 users is now

Communigate Pro 50 users  999 €/year (1.67 € user/month)
the Kaspesky Antivirus  50 users  389 €/year (0.65 € user/month)
the Kaspesky Antispam 50 users  389 €/year (0.65 € user/month)

If you renew everything the cost is 1770 €/year (2.96 € user/month)

I understant that the price is much high of your last year so for this year we will offer you 15% discount on the Communigate side and include the Antivirus with a total price of 1238 €/year (2.06 € user/month)
