Review summaries and opinions

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

ROI

Sentiment score
4.4
Microsoft Defender's financial benefits are unclear, best within E5 suite, and difficult to assess against AWS for mixed solution users.
Sentiment score
5.0
Proofpoint Email Protection offers high ROI with reduced breaches and enhanced efficiency, significantly improving threat blocking and user satisfaction.
Organizations typically do not rely solely on Microsoft products to avoid putting all eggs in one basket, which presents a challenge for maximizing ROI.

As a Microsoft partner, we receive significant discounts, making the solution affordable for us.

They are familiar with Microsoft products but are not direct Microsoft staff, which is an area needing improvement.

It is very resource-intensive, consuming a lot of memory and CPU.
Security Specialist at Prudential Systems Japan
If Microsoft experiences downtime, this solution goes down as it is a SaaS-based solution where we have no control.
Cloud Security Engineer at a computer software company with 51-200 employees

Room For Improvement

Microsoft Defender Vulnerability Management needs simplified configuration, better integration, faster updates, and advanced features for improved security and efficiency.
Proofpoint Email Protection needs a more intuitive interface, better detection, simplified integration, cost efficiency, and improved support.
This scoring should be for specific industries as well. If I belong to the healthcare industry using Microsoft Defender Vulnerability Management, it should provide me with a risk score and show how I fare against the risk score of my industry.
DGM. Technical Security at a tech services company with 10,001+ employees
A vulnerability I patch within 15 minutes takes 24 additional hours for an update.
information Security and IT Manager at Discover Dollar Technologies Pvt Ltd.
The product is not stable; it often uses excessive memory and CPU, which makes it slow.
Security Specialist at Prudential Systems Japan
The older legacy user interface just took a little to work with, and the new unified interface, as it was able to do more and more of the functionality of the old one, the product just got easier and easier to use.
Sr Security Engineer at a comms service provider with 201-500 employees
In addition to the UI improvements, I would appreciate an increase in the speed of the tasks being processed on the pod.
Security Specialist at a leisure / travel company with 10,001+ employees
There are pros and cons to that, but I would suggest maintaining a good balance between security protection and operational impact.
Senior Security Engineer at Cloudflare
 

Setup Cost

Microsoft Defender Vulnerability Management offers competitive pricing in industry, though costs can be complex, especially for non-partners.
Proofpoint Email Protection is costlier than competitors, but its superior security features justify the premium pricing for users.
Overall, every organization wishes for cheaper options, but we look at the security side as well, so we are good for now.
Senior Cloud Security Consultant at MetLife
For non-partners, however, the cost could be seen as higher, between seven to ten.
COO at Floating-Dot Technology LTD
The pricing is reasonable, and it's included in the whole Microsoft E5 bundle, so it's all-inclusive.
Corporate Planner at MISC Berhad
Customers pay around $90,000 yearly for a 1,000-user organization, with the subscription license being the main expense, apart from implementation fees.
Products and solutions director at ITVikings
Given my other experience with other vendors, I think they are a bit on the high end and a bit on the pricey end for the email security functionality that we were using.
Sr Security Engineer at a comms service provider with 201-500 employees
Although it is a bit costly compared to Mimecast, Defender, and Cofense Vision, it is efficient and strong in security, so I do not mind the cost because I will not reduce my security risk.
Senior Solution Delivery Lead Cybersecurity at International Olympic Committee – IOC

The feature for customizing to region-specific and domain-specific requirements in healthcare is particularly beneficial.

Featured Reviews

Cloud Security Engineer at a computer software company with 51-200 employees
Has helped with regional threat monitoring but needs better documentation and real-time capabilities
The documentation from Microsoft needs significant improvement. The documents are disorganized, with one document linking to another, making the steps unclear and difficult to follow. Regarding updates, it is not truly real-time as it takes between eight to twelve hours for updates to occur. It would be beneficial if updates could happen more quickly, perhaps within 10 minutes to half an hour. Support for integration and documentation needs to be more straightforward. The pricing is expensive, even though it is part of the E5 package.
Siva_Prasad - PeerSpot reviewer
Principal Consultant at Infosys
Email defenses have reduced phishing incidents and protect sensitive data across our enterprise
As things are evolving and threats develop in unpredictable ways, Proofpoint must adopt AI solutions and agentic solutions more aggressively and provide them to customers as part of service offerings. Inbuilt AI solutions would add more value and make Proofpoint a more premium choice for customers. With the help of AI solutions, agentic AI, and generative AI capabilities, the product would be more efficient than it currently is. Filtering false positives is highly challenging because it is impossible for humans to identify which emails are genuine and which are spam. Proofpoint should focus more on this area with back-end agents or other tools. Proofpoint should decide which emails are genuine and which are spam so it is not a challenge for end users. When receiving an email, end users should not have to determine whether to respond or not. Proofpoint should not release such spam emails and should strictly block such spam and spoof emails based on connection IPs. Currently, false positives occur in the product, and while this occurs in every product, it is an area where Proofpoint can focus on improving and reducing false positives. One email is enough for an end user to be deceived and lose money, so addressing this area is critical.
