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

"This solution is easy to understand and easy to configure."
"It will take the blow rather than our applications should an attack occur."
"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare is simple to use."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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."
"It offers great security against malware and other threats."
"It has a really nice web-based administration console."
"We use the solution in all our environments. We use it for remedy tickets and give them updates. It was our main communication point."
"What I like most about Microsoft Exchange Online Protection is its integration with Windows, so we have one central view for all alerts and incidents."
"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."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
"The initial setup of Microsoft Exchange Online Protection was easy."
"Microsoft EOP's most valuable feature is a shared mailbox."
 

Cons

"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"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."
"Feedback could be enhanced."
"Our subscription plan for the solution has a limitation of bot signatures."
"Cloudflare DDoS has poor technical support."
"For the topic of improvement, providing some training material is one of my suggestions."
"The security features could be better."
"They should specify the difference between Defender for Office 365 and Exchange Online Protection."
"If a company wants to put in line back-to-back anti-spam solutions, they need to work on that part because Microsoft recommends either you use EOP as a front line or you don't use it."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"The product could be more stable. Microsoft products could be more stable because sometimes, even though they are updating some things, we cannot find those updates."
"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."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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 is not that expensive."
"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."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The prices are slightly expensive."
"It's a high price."
"The product is bundled with Microsoft 365."
"The pricing of the solution is reasonable."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"The tool's pricing is excellent."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
"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."
"The solution should reduce the cost."
