Has supported data retention and export tasks while leaving room for greater automation and feature expansion
If we can have more APIs open for Google Vault, that would be great, and instead of doing it manually, it would be better to do it programmatically. I think there is an API available with Google Vault, though I'm not certain about it. I have never used Vault programmatically, but if APIs exist, then it's beneficial, and if there aren't any, we should have the capability for programmers to create some sort of scripting so they can fetch the data. I assess the export feature in Google Vault in terms of ease and efficiency as quite efficient because most of the data we want to see is available in MBOX and PST formats. If possible, I would want to see Google Vault support additional formats such as iCal, iCad, or CardDAV, which are for iPhone users.

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

"In my opinion, the search functionality is the best feature."
"In my opinion, the search functionality is the best feature. With Google Vault, we can quickly search for any email within Gmail accounts. And then we can get further information, such as if you want the full header or want to know any extra details about the emails."
"It is a very stable solution...It is a very scalable solution."
"One of the noteworthy aspects is that nothing ever gets deleted, which is convenient."
"My impression is that the initial setup process is not that difficult."
"The audit part of the tool is the most useful for me."
"The most valuable feature of Google Vault is its reliability."
"Search feature is valuable for our customers."
"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."
"The initial setup is easy."
"The Large File Send feature comes in handy when you have to send fairly large attachments."
"If I had to mention one or two things that bring the biggest benefit, I would say the security of the emails and dealing with everything."
"The reviewer gave Mimecast Email Security a rating of 10 out of 10."
"The most valuable feature is the DMARC Analyzer."
"URL inspection works pretty well."
"The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
 

Cons

"eDiscovery could be improved with additional information and an easier way to retain it."
"Customer service has been a bit lacking."
"The price of the solution could improve and the search could be easier."
"For us, customer service has been a bit lacking, probably with a rating of a five out of ten."
"My personal opinion is that Google Vault could improve if they could have a similar version to Microsoft 365 where you can have an eDiscovery manager account. With this, you can separate a regular person from an organization and just transfer the specific files."
"The knowledge base is not as in-depth as it should be."
"So, when doing a search, perhaps in some instances when you use terms, the information is not very precise in the sense that I'm not getting what I'm looking for. And in some instances, the information, not all the time, but in some instances, it might not be accurate. For example, when doing a search, if you use too many terms, it might not return any results."
"It would be nice if Google would let us download the data in different formats."
"The installation is not so straightforward."
"Lately, Mimecast's outbound mail servers have been regularly blocklisted by spam filters. That didn't happen a few years back, but it seems to be a more frequent problem these days. When a server is blocklisted, it means all of my outgoing mail ends up in the recipient's junk mail. That affects my reputation and business confidence."
"The solution is very expensive."
"Mimecast Advanced Email Security needs to improve in this area because they are only focusing on a particular set of problems which is on email and human risk, whereas companies that need a slightly bigger picture will look elsewhere."
"I don't think it's ideally suited for maybe a smaller business environment, like, for example, for companies with less than 100 seats."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"The price could be better, it should be reduced."
"External security features need improvement."
 

Pricing and Cost Advice

"The pricing is fairly cheap."
"If you have Google Enterprise, then Google Vault is free to use."
"Google Vault is a cheaply priced product. Monthly payments are to be made towards the licensing costs attached to the solution. There are no extra costs apart from the licensing costs attached to the solution."
"The solution is expensive."
"Google Vault comes as part of a package deal for us."
"Last year, the price was randomly increased and our customers were really facing a challenge around this. Google launched new pricing under different plans, where formerly there were only three plans, and now there are four, each with their own separate usage allowances. I think it's good, though. The basic plan is now the Business Starter plan, and many customers find this plan very convenient and minimal in price. Overall, the pricing for all the plans is good."
"The customers can select the license packages as per their requirements."
"It is a bit expensive."
"I'm always going to say the price needs to be lower, but it's reasonable."
"The solution is expensive."
"The product price is moderate. I rate the pricing a five out of ten."
"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."
"The product has good pricing in terms of return on investment."
