Useful for collaboration and storage but improvement is needed in API integration
The solution has traditional SSL integration, SAML, and Federation Services. In its latest version, it added SAML integration. However, it needs to work on API integration, especially for dashboards or integration with SAP for log and data system management. It doesn't yet have the kind of API that Google and Microsoft provide for synchronizing users with Active Directory. I think IceWarp needs to improve in a few areas. They have two types of admin consoles - a web-based one and a remote one. I'd like to see these combined into a single web-based admin console. The log reading and information system also needs improvement. The current way of showing incoming and outgoing logs isn't very clear. For new users, it's hard to understand these logs, especially compared to Office 365 and other systems with easier-to-read logs. They should also add an export option to get all logs with a single click whenever we need them.

Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

Quotes from Members

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

Pros

"IceWarp has multiple applications that are easy to use for many people."
"The most valuable feature of IceWarp is the chat rooms and file-sharing, they are useful. It is convenient that everything is in one place. You can easily share and collaborate documents, making the program's unity a significant advantage."
"The product is used very extensively in my company since we have around 1,500 users using it. Also, there is no requirement for any administrators to manage the product by the people who own the solution."
"The solution's voice services work well for our company."
"An effective, functional, very good tool for controlling resources."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
"It's scalable and stable."
"Its price is the most valuable. It is definitely one of the lowest price solutions."
"The solution is scalable."
"It offers an easy initial setup."
"The most valuable feature of Mimecast Mailbox Continuity is real-time alerts."
"What I like about the integration is that it is directly into Microsoft 365, users can use their Microsoft 365 credentials to log into the portal and access their mail."
"Email security is the most valuable feature of the solution."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"Its administration console is very easy to use. The administration console is absolutely important because you interact with the platform through it."
"The setup was easy."
 

Cons

"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"The tool's configuration capabilities are not straightforward. Apart from that, if I want to archive emails into a vault so that they can be retrieved again later, the integration doesn't work, and IceWarp crashes."
"The solution has traditional SSL integration, SAML, and Federation Services. In its latest version, it added SAML integration. However, it needs to work on API integration, especially for dashboards or integration with SAP for log and data system management. It doesn't yet have the kind of API that Google and Microsoft provide for synchronizing users with Active Directory."
"Our customers sometimes have problems receiving mail."
"The exchange compatibility mode is rather limited. Their technical support can also be better. They only provide online support, and there should be some option for escalating."
"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."
"Technical support has been slower than it was in the past, likely due to the pandemic."
"The interface isn't the best. How everything works on the back end is confusing."
"The feature that should be included is to remove the block on the encrypted files."
"The price could be better, it should be reduced."
"Certainly, the primary area needing improvement is Mimecast's customer support. Our experience as Mimecast customers has been less than satisfactory. Even when raising a priority ticket, the response time is unacceptably long, often taking around five to six hours. This level of service is disappointing. Additionally, there have been recurring service disruptions in the UK region, leading to extended email delays due to various service issues. This year alone, we've encountered such problems on approximately four occasions."
"As for areas for improvement within Mimecast Web Security, I believe there is quite a lot that can be improved."
"They should improve the cookies management feature."
 

Pricing and Cost Advice

"Pricing and licensing is very competitive and in some cases, cheap."
"Costs far less than other solutions."
"There are various licensing plans available based on geographic zone."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"I don't see any challenges for the Indian market. For example, 1 GB is available for around 399 INR, and 2 GB for 499 INR. They offer a range of plans, from basic to professional and enterprise, with multiple features. IceWarp's aggressive pricing is competitive compared to other market solutions like Zoho and Microsoft. One significant advantage is that IceWarp does not impose user capping like Google and Microsoft, which allows for substantial cost savings and flexibility in user conversion."
"It is definitely one of the lowest price solutions."
"The solution is inexpensive which is its main benefit."
"The solution is priced well."
"The product has good pricing in terms of return on investment."
"The licensing costs are per-user for the product that you get with them."
"I'm always going to say the price needs to be lower, but it's reasonable."
"For what it is, the product is overpriced."
"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."
"The product price is moderate. I rate the pricing a five out of ten."
"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."
