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.

Experience with offsite backup enhances data integrity and reduces on-premise reliance
One of the features of Veritas Alta SaaS Protection that customers are looking for is immutability. This is the most important feature. With the cloud, Veritas Alta SaaS Protection is actually in the cloud, which means they have unlimited space to do their backups. They can expand on a need-to-need basis. The automated recovery feature of Veritas Alta SaaS Protection makes the recovery much easier, as opposed to earlier methods where we were using scripts to do the restore. Currently, it's automated so you just do a click. You select the feature in a graphical interface, making it easy to use even for a newbie.

Quotes from Members

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

Pros

"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"The product's scalability is good."
"It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"The insights provided with Microsoft Defender for Office 365 are helpful because it comes with the E5 license, and by default, we can use a lot of capabilities."
"Some of the tool's best features include an enhanced dashboard and strong security features compared to native Veritas. Our environment is entirely automated."
"It's very comprehensive. It's one of the first brands to appear in its field."
"he most valuable feature is that it's not so intrusive with computer resources."
"We're comfortable using this kind of technology. It's user-friendly."
"The automated recovery feature of Veritas Alta SaaS Protection makes the recovery much easier, as opposed to earlier methods where we were using scripts to do the restore."
"Veritas is loaded with features because the appliance is ready to integrate with the cloud in cases where the customers have a hybrid or cloud environment."
"I think the most important feature is the ability of SaaS Backup to cover all modules proposed by Office 365, because competing solutions don't cover the total scope."
"The most valuable features are the ease of administration and the ease of configuration."
 

Cons

"In one of the reports I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help."
"Microsoft Defender for Office 365 is not up to the mark in comparison with Wiz or Palo Alto."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"The product must provide better malware detection."
"The GUI is sometimes slow to fetch the device report and could be improved."
"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"The backup reports and the dashboard need improvement."
"Technical support can be improved."
"The tool can be improved in terms of maintainability and flexibility, especially as companies grow larger. In these aspects, I feel Veeam is better for cloud and operational purposes."
"The solution does lack a lot of features, and we're considering switching."
"In the future, we would like to see support for virtualized machines."
"The technical team wasn't very helpful."
"Currently, it isn't possible to use anything other than Veritas cloud to back up to. I think today it's important to cover the three major cloud provider: GCP, Azure and AWS."
"The usability of the solution isn't the best."
 

Pricing and Cost Advice

"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"The pricing is normal. Considering its popularity, it's not overpriced."
"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."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"The product is expensive."
"It's a user-base subscription."
"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."
"I would rate this solution's pricing as five out of five."
"The tool is expensive compared to Veeam."
"The program is quite expensive."
"This solution is not cheap and not expensive but priced in the mid-range."
"SaaS Backup isn't the most expensive solution."
