The most appropriate scenarios to implement email security is in companies that want to protect the use of electronic mail since it is one of the security breaches that are currently used to perform any type of attack. Very effective integration with Office 365 and it is highly recommended to add the functionality of advanced malware protection
If you don't have a huge budget and want something that works with minor quirks here and there then Zoho Mail is definitely something you should look into. For half the price of Google G Suite or Office account you get 5GB of storage per user and can send up to 25MB emails without restrictions. Great for small businesses in my opinion. I have had some issues with their spam filter, but we use SpamTitan and just shut off the one that comes with Zoho Mail. Zoho's spam filter isn't horrible but you should definitely use something in addition or instead of what comes with Zoho.
I really like that there is a free version in which a single user can be created. It is really useful because it allows you to evaluate each characteristic of the service without having to buy it.
I also really like the visual aspect of the inbox, which is partially customizable. Because you can make small changes such as changing the color, the language, and among other things.
It is very easy to use and does all you need. It sends newsletters to their own folder. A notification folder for more important things. The Spam folder collect the right amount of spam emails
Cisco TAC support is very good since they have engineers available 24 hours a day, 365 days a year. Important to mention that you must have the support of the solution enabled to be able to receive a response from TAC and that we can be taken care of. The only drawback may be that they will not be able to see settings of the email provider you use.
I have spoken with Zoho several times and their support is always friendly and helpful. I have always been asked for security pins and codes when seeking assistance which helps me to feel my accounts are secure and I have never had to wait on hold to speak with someone for more than 5 minutes. They always seem to have someone available to help. If you call asking for instructions on how to do something they gladly walk you through the process and if you just need something done and don't have time to do it yourself they will happily customize whatever you need without you having to spend all day with it.
Cisco was at least better than or equal to the others but within our budget. It provided all of the services of anti-spam, content filtering, anti-virus, DLP, encrypted email service, scalability, and more than the others. Cisco name and reputation were also key in our decision.
Zoho is free. Also, there is no need for a separate IT guy for creating mail, or if any issues come you don't have to find anyone anyone can check and fix all issues from their super admin panel. Zoho overview is much better than outlook and its appearance of getting mail popup and functionality is better than outlook. My friend suggested for this and also after using I have referred my friend
