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

"My impression is that the initial setup process is not that difficult."
"In my opinion, the search functionality is the best feature."
"Google Vault retains all deleted data from the previous four years, acting as backup security so this vital information can be made available to anyone who needs it."
"Overall, it's a very good product, and I recommend it with some consideration for future improvements."
"Data retention is very valuable to us."
"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."
"What I appreciate about Google Vault is that one of the best features is the ability to use retention policies; it covers mail, chat groups, calendars, sites, Drive, and Google Voice, and the data will remain in Google Vault even if it gets deleted by the user accidentally or intentionally."
"Search feature is valuable for our customers."
"Mimecast has some good support services in place."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"The reviewer gave Mimecast Email Security a rating of 10 out of 10."
"The security is pretty good, and that's why we're going to upgrade to an even more advanced package. We used it when we had a power issue, and it works. It has been pretty reliable, and the support has been quite good."
"The initial setup is easy."
"The solution offers good technical support."
"The Large File Send feature comes in handy when you have to send fairly large attachments."
"I have been satisfied with Mimecast Email Security as a good solution."
 

Cons

"Customer service has been a bit lacking."
"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."
"It would be nice if Google would let us download the data in different formats."
"Searching could be improved. There's a lot of limitations when searching with Google Vault."
"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."
"Many of our customers are facing problems related to backup and data splitting, and when they ask Google technical support about the reason for the data splitting, they haven't received a proper answer."
"One thing I've noticed is that it splits the data files into multiple parts, like the PFT files. For example, when there is a large data size of any account, the backup process splits it into many files. This can be confusing and not very efficient when trying to manage the backups."
"EDiscovery could be improved. It's used for searching, holding, and exporting data for Vault and I believe it should be updated."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"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 interface and the documentation could be improved."
"It analyzes patterns but sometimes overlooks suspicious indicators."
"Technical support has been slower than it was in the past, likely due to the pandemic."
"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."
"As a user, the user interface of the management console could be upgraded, for example."
"External security features need improvement."
 

Pricing and Cost Advice

"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 solution is expensive."
"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."
"Google Vault comes as part of a package deal for us."
"If you have Google Enterprise, then Google Vault is free to use."
"The pricing is fairly cheap."
"The licensing costs are per-user for the product that you get with them."
"The product has good pricing in terms of return on investment."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"I'm always going to say the price needs to be lower, but it's reasonable."
"The price of Mimecast Mailbox Continuity is expensive."
"The product price is moderate. I rate the pricing a five out of ten."
"It is a bit expensive."
"The solution is expensive."
