This product has been working great for my client. I do not have any dislikes as it is perfect so far. It has been very useful in keeping track of mail servers, domains, clients, etc., and ensuring that they are all secure. I would highly recommend this to other businesses who need to ensure their mail server is secure and safe from hackers or malware. The best part about this product is that you can configure it to suit your own needs. You can also easily monitor its performance with graphs and charts. I am using this product to keep track of emails sent from different domains. It helps me find out which domain sends spam most frequently and which ones require extra attention. The best part about Securitie gateway is that it was easy to set up for use with MS exchange as well outlook - I had been looking at other providers such as O365 but found them difficult/costly in setup etc so decided this would be good option - We also like its flexibility once deployed within network (eg can view logs from anywhere) rather than having physical access only which we disliked when using similar products beforeSecured communication by blocking malware & phishing attacks.
