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

"The groupware module is the most valuable feature."

"The solution has a very good log-in to the UI when compared to other solutions."

"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."

"An effective, functional, very good tool for controlling resources."

"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 is easy to manage and includes features such as smart documents and the archiving of user data."

"The solution's voice services work well for our company."

"The TeamChat feature has been really good for our email management. It lets us collaborate, share files, and invite guests like Google Spaces or Microsoft Teams. I like the two-factor authentication for security. However, they need to improve their document collaboration tools, as their Word, Excel, and PowerPoint features are basic compared to Microsoft and Google."

More IceWarp pros

"URL inspection works pretty well."

"The solution is pretty straightforward to use and easy to set up."

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

"We like the content filtering and secure messaging features."

"Mimecast has some good support services in place."

"I would rate Mimecast Email Security a nine out of ten."

"Due to our specialized use case, that HIPAA dictionary really comes in handy."

"Mimecast certainly helped my customers reduce phishing emails."

Cons

"Support should be improved. Most of the time, the queries are not resolved within the SLA."

"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."

"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."

"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."

"The solution should improve the mailing list feature. Google has a similar feature where you can automate sending files to different people in a sequence, but that feature is no longer available in the current version of IceWarp. Other features may also have been removed in the current version."

"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."

"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."

"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."

More IceWarp cons

"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you, but that is, unfortunately, kind of becoming a trend with everything. In terms of features, I haven't had any complaints. However, I don't like the fact they moved to a paid training subscription model. They used to have a lot of free webinars for training, but they have started to charge for them in the past year."

"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."

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

"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."

"As for areas for improvement within Mimecast Web Security, I believe there is quite a lot that can be improved."

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

"The solution is complex and not easy to use."

"The installation is not so straightforward."

Pricing and Cost Advice

"There are various licensing plans available based on geographic zone."

"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."

"The license is based on the number of users."

"Our licensing is on a yearly basis. There were no additional costs."

"Pricing and licensing is very competitive and in some cases, cheap."

"The solution is inexpensive which is its main benefit."

"Costs far less than other solutions."

"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."

More IceWarp pricing and cost advice

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

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

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

"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."

"It's an expensive solution."

"The price of Mimecast Mailbox Continuity is expensive."

"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."
