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

"It's relatively simple to use."

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

"The user interface is good."

"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."

"KerioConnect has integration with 365. We can use Outlook, which has its client and can be used with Apple devices. It integrates with the App Store and Microsoft Office. It has a smart router. The spam filtering and antivirus are good."

"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."

"We use the solution as a mail server. It connects with Outlook and is used for calendaring and similar tasks."

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

More KerioConnect pros

"I recommend Mimecast based on customer requirements and budget."

"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."

"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."

"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."

"The positive impact of Mimecast Advanced Email Security on our organization is evident in how it has drastically reduced spam emails and improved our data security."

"It offers an easy initial setup."

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

"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."

Cons

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

"Most of our clients use Outlook and Kerio Connect. Occasionally, Kerio can be a bit slow. They could make it faster to get onto the web interface without so much load time. It's just slow with Outlook, however, for some reason."

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

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

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

"We are considering switching to Microsoft Exchange. One reason is that it doesn't improve our workflow and doesn't integrate well with Microsoft 365 applications."

"It could be simpler to use and install, but I still wouldn't use it because there isn't a compelling use case."

"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

"The filtering needs more flexibility."

"Mimecast Email Security is somewhat expensive compared to the competition in the Indian market, and the local presence is lacking as they do not have a local representative currently."

"The installation is not so straightforward."

"Mimecast needs to reduce the number of false positive emails; a big pain point for us."

"External security features need improvement."

"The solution is expensive in comparison to similar solutions."

"The price could be better, it should be reduced."

"The solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."

Pricing and Cost Advice

"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."

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

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

"The solution is expensive."

"The product has good pricing in terms of return on investment."

"I'm always going to say the price needs to be lower, but it's reasonable."

"The price of Mimecast Mailbox Continuity is expensive."

"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."

"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."

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

"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."
