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.

Improves threat visibility and response while reducing manual tasks and training users against phishing

I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.

Quotes from Members

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

Pros

"Overall, it's a very good product, and I recommend it with some consideration for future improvements."

"I think the most valuable features are Gmail and Drive, and the solution is also very helpful with Google Chat messages because sometimes you might be missing some information and you can search for it in Google Vault, a very helpful feature for our customers."

"Google Vault is a solution we can use for the data export of end-users."

"The audit part of the tool is the most useful for me."

"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."

"You can retrieve any type of data; for example, if a user accidentally deletes data, as an admin with access to Google Vault, you can easily restore the deleted data."

"Data retention is very valuable to us."

"One of the noteworthy aspects is that nothing ever gets deleted, which is convenient."

More Google Vault pros

"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."

"It has significantly decreased my time to detection and response."

"We have seen a return on investment because if we would have received a phishing email, Microsoft Defender for Office 365 would help out to detect the threat instead of crashing down the whole company."

"The features I appreciate most about Microsoft Defender for Office 365 are admin notifications for potential threats along with protecting our Microsoft apps such as Outlook from potential phishing attacks."

"The coolest feature of Microsoft Defender for Office 365 is its ability to look for phishing emails."

"Microsoft Defender for Office 365 has decreased my time to detection and time to respond by one hundred percent."

"The most valuable feature is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."

"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."

More Microsoft Defender for Office 365 pros

Cons

"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."

"EDiscovery could be improved. It's used for searching, holding, and exporting data for Vault and I believe it should be updated."

"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."

"Google Vault lacks speed."

"Customer service has been a bit lacking."

"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."

More Google Vault cons

"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."

"I think Microsoft Defender for Office 365 can be improved by creating more educational pieces about not just looking for malware."

"Its price should be improved. Its cost is a major concern for us."

"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."

"The product must provide better malware detection."

"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."

"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."

"You should be able to deploy Defender for every subscription without the need to add servers."

Pricing and Cost Advice

"The solution is expensive."

"If you have Google Enterprise, then Google Vault is free to use."

"Google Vault comes as part of a package deal for us."

"The pricing is fairly cheap."

"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."

"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."

"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."

"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."

"It is much more expensive than using another solution because we have had to include some options and upgrade our license."

"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."

"The pricing has become expensive."

"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."

"The product is very expensive."

"From the pricing point of view, like any other product in the market, there is scope for negotiation."
