Rahul Gill - PeerSpot reviewer
GWS/M365 Consultant at a tech services company with 10,001+ employees
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.

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 most valuable features are automatic document and email retention."
"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."
"Overall, I would rate Google Vault a ten out of ten."
"The most valuable features are automatic document and email retention."
"Google Vault acts as a great method for retrieving files from Google Drive and Gmail."
"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."
"Overall, it's a very good product, and I recommend it with some consideration for future improvements."
"The audit part of the tool is the most useful for me."
"The solution is pretty straightforward to use and easy to set up."
"My advice to those considering this product would be to go for it."
"The setup was easy."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"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 interface of this solution is very easy to navigate and user-friendly. There is no delivery in email and other communications, making it reliable. The configuration is relatively easy."
"The product is good; to date, we have not faced any challenges."
"It offers an easy initial setup."
 

Cons

"Google Vault needs to improve its data export timing because sometimes, it takes a very long time to export the data."
"The knowledge base is not as in-depth as it should be."
"eDiscovery could be improved with additional information and an easier way to retain it."
"Although it does a good job of searching through data and exporting it, I feel that Google Vault should have more export options available to the user."
"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."
"Searching could be improved. There's a lot of limitations when searching with Google Vault."
"Customer service has been a bit lacking."
"Searching could be improved. There's a lot of limitations when searching with Google Vault."
"While it's quick and easy, the initial setup could be more user-friendly."
"The lock in is very, very tight. It is impossible to move out of Mimecast to a different product, like Proofpoint or 365 ATP, and keep the chain of custody for every email that I've archived."
"While it's quick and easy, the initial setup could be more user-friendly."
"The solution is very expensive."
"The solution is very expensive."
"The solution is complex and not easy to use."
"Technical support has been slower than it was in the past, likely due to the pandemic."
"Its pricing can be improved. It is a bit expensive."
 

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."
"The pricing is fairly cheap."
"If you have Google Enterprise, then Google Vault is free to use."
"Google Vault comes as part of a package deal for us."
"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."
"The product price is moderate. I rate the pricing a five out of ten."
"The customers can select the license packages as per their requirements."
"It's an expensive solution."
"I'm always going to say the price needs to be lower, but it's reasonable."
"It is a bit expensive."
"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."
