Featured Reviews

Carlos Alam Hernandez Baruch - PeerSpot reviewer
The solution enables seamless security management and fosters a learning environment
Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions. For the solution stopping us for e-learning, I appreciate the concept yet need more resources or courses in Mexico, preferably in Spanish. Certifications are easy, however, I require more real-world environments and instructors.
Amber Worth - PeerSpot reviewer
Retrieves data from quarantines and easy to read logs with robust security features
Some of the searchability when looking for specifics in Exchange logs is tedious. Although eventually the information is located, it can be difficult if detailed information is lacking. Improving the search process by allowing searches with different types of parameters and facilitating searches within emails would be advantageous. Simplifying interfaces would also be appreciated.

Quotes from Members

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

Pros

"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Enables me to work from two locations."
"I'm very satisfied with the environment and the dashboard."
"Cloudflare DDoS mitigates DDoS attacks."
"The best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"This solution is easy to understand and easy to configure."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
"We like the holding facility that is available for potentially suspicious URL's. This allows a real-time review to be performed before the email reaches a users inbox."
"The solution uses artificial intelligence and machine learning, so you don't need train it to detect something. The detection and response times are short. It's an excellent product."
"We can migrate seamlessly without any disruptions to our operations."
"Microsoft Exchange Online Protection (EOP) is used essentially for email filtering, acting as an anti-spam and security product for email."
"Microsoft EOP's most valuable feature is a shared mailbox."
"We use the solution to receive emails. We do not use the calendar function as our clients are slow adaptors to the latest features."
"The security features provided by Microsoft are robust."
 

Cons

"Operating and tuning the product is difficult."
"For the topic of improvement, providing some training material is one of my suggestions."
"They don't have a person to provide support for customers using the solution under their free plan."
"The response time for support must be reduced."
"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"Feedback could be enhanced."
"Our customers no longer use Cloudflare because its service is subpar."
"The onboarding process can be improved a little bit."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"The licensing can be on the expensive side, especially in the cloud space."
"Microsoft has some training portals, but more could be developed."
"The solution can be complex at times. It would be nice to have the on-server version. It needs to improve the stability as well."
"Not all settings can be configured automatically and most still require manual configuration. However, there is an automation tool available that can be used to input all the configurations either as a script or a tool it would be helpful."
"Online Protection has an issue in that it doesn't provide an option to stop impersonation."
"When you're using a Microsoft product solution, you can scale it, but if you're not, there are limitations."
 

Pricing and Cost Advice

"The solution is not that expensive."
"The prices are slightly expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution's pricing lacks transparency."
"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."
"Cloudflare Zero Trust Platform's pricing is good."
"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."
"The solution's pricing is subscription-based rather than a yearly licensing cost. Pricing is based on the size of the environment and company and can be expensive."
"It is a low-price solution."
"On a scale of one to ten, where one is cheap, and ten is very expensive, I rate the pricing a six. For licensing, we can make monthly or yearly payments. Right now, we pay 5 USD per month to secure a person's license."
"Regarding the price, it's comparable to other service providers. We've also looked at Check Point's offerings, and the pricing doesn't seem to be an issue."
"It's a high price."
"The solution is priced high and could be less expensive compared to other solutions."
"The price could be lower."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
