A seamless setup ensures smooth communication with comprehensive support

We remain a partner with Sophos and use XG S Firewalls without AWS implementation. We only use Sophos endpoint and Sophos Central. We host some clients on-premise while others we host remotely. The VPN connection is easy and proprietary, so it's not open to any other VPN clients. Communication with other mail servers is seamless. It can communicate with Gmail and Outlook without issues, provided the DNS settings are correct. We monitor our servers and security logs, implementing GeoIP blocking. We frequently block China and India IPs due to brute force attacks on our servers. We have extensive experience with KerioConnect. Backing up and maintaining it is straightforward compared to Microsoft Exchange, making it administrator-friendly. On a scale of 1-10, this solution rates an 8.

Advanced email filtering has blocked massive spam volumes and prevents unauthorized data leaks

Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts. Streamlining this could improve overall usability and security management for users. Reporting is another area needing improvement in Mimecast Advanced Email Security, as the reports provided are not very easy to decipher. With artificial intelligence being integrated into various tools including Mimecast Advanced Email Security, I believe there is potential to enhance functionality, enabling users to ask specific questions and retrieve concise answers instead of overwhelming data. I choose a nine for Mimecast Advanced Email Security because improvements such as better user interface and artificial intelligence integration features would greatly enhance its usability. While no tool is perfect, these adjustments could greatly elevate Mimecast Advanced Email Security's capabilities.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Kerio Connect is secure, flexible, and easy to control from the user interface. It has many security features able to be controlled from one place, such as anti-spam. I have found it very convenient. Additionally, you can analyze log files and share folders which is helpful."

"Backing up and maintaining it is straightforward compared to Microsoft Exchange, making it administrator-friendly."

"As long as the operating is stable, the Kerio connect will be very stable as well, so we don't have any problem with it."

"What I like most about Kerio Connect is that it supports ActiveSync, and that is its most critical feature. The solution is also a nice, simple, robust, and stable mail server."

"It's relatively simple to use."

"Kerio Connect is secure, flexible, and easy to control from the user interface."

"This solution is our SMB alternative to Exchange, installed for more than forty SMB customers in a Linux environment with all of the collaboration features."

"We have contacted technical support a handful of times and received some assistance."

More KerioConnect pros

"The interface of this solution is very easy to navigate and user-friendly. There is no delivery in email and other communications, making it reliable. The configuration is relatively easy."

"We're now certain business-critical mail is perfectly protected in multiple ways."

"Mimecast has been in the market for a long time; it's a good tool if you want to simplify your operations and a good tool for removing on-prem appliances that otherwise you would need to do with the protection that Mimecast provides."

"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."

"URL inspection works pretty well."

More Mimecast Advanced Email Security pros

Cons

"The search and archiving documentation capabilities need to be stronger."

"Having a native Outlook map integration would make Kerio Connect better."

"KerioConnect continues to improve with regular updates throughout the year. They must be added to the roadmap, which requires approval."

"I would like to see better support from their support team."

"We cannot compete with them because they're fully integrated with their applications."

"Most of our clients use Outlook and Kerio Connect. Occasionally, Kerio can be a bit slow."

"This is just a cost, it's not something that's driving our business forward; it's just foundational."

"The solution could improve the redundancy because we only have one copy of the Kerio Connect server on our hardware. The next step for us is to move to the cloud and if Kerio does not have a cloud version available they should release one"

More KerioConnect cons

"Technical support has been slower than it was in the past, likely due to the pandemic."

"The installation is not so straightforward."

"The solution should include more AI features instead of Mimecast's more general static configuration tooling."

"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."

"Its pricing can be improved. It is a bit expensive."

"The detection rates are an area for improvement."

"The interface and the documentation could be improved. They can also include some more training resources and content like video. While setting things up, I had to search for the information quite a bit. It took me time to find the correct way to do something. The information is there, but it is sort of all over the place. They can create a better help knowledge base or help portal. It retains your email for 45 days. They can maybe increase this duration."

"The product's interface could be improved to be more user-friendly."

Pricing and Cost Advice

"The price of Kerio Connect is better when comparing it to others solutions."

"KerioConnect has a first-time cost and yearly subscription. It is not expensive."

"The pricing is about $3 per mailbox per month."

"The solution's pricing depends on how long you plan to keep it because you pay on a per-year basis. You might have a one-time setup cost for something like Microsoft Exchange or a Linux mail server. I'd say this solution is expensive on a per-year basis, almost 2000-3000 dollars annually. It doesn't seem to pay off yet, so we're considering switching to another product."

"The customers can select the license packages as per their requirements."

"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."

"The licensing costs are per-user for the product that you get with them."

"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."

"The product price is moderate. I rate the pricing a five out of ten."

"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."

"For what it is, the product is overpriced."

"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
