Cloud security has improved remote access and has reduced costs for smaller client sites

I have used Cloudflare One's Identity-Aware Proxy, and it is quite straightforward from what I have seen so far. The app registration on the Azure side integrates fully into Cloudflare, and I am very satisfied with that part because it is easy to set up. The integration of Cloudflare One's Secure Web Gateway and Zero Trust Network Access works without any issues. That part is pretty automatic, and if you complete the rest of the setup, it comes together by itself with no issues from my side. What makes it nice is that we can actually start replacing on-site firewalls at this stage for the smaller clients because it does not matter if they go to a coffee shop or work from home; they are still secured by the same connection. The hops get shorter and you get better latency. We have done testing to see if it is better. One thing that we did notice with our proof of concept with our current client is that they have people connecting from the UK. When they used their previous VPN solution, uploading CAD drawings and other files to the server took a long time. They mentioned that it is much quicker on Cloudflare One's solution. I definitely believe that is part of the improved performance, and I am satisfied with that as well. What is nice about Cloudflare One is that it makes the setup easier and also easier to train technicians to maintain it. Compared to legacy systems, we do not need to get fancy firewalls in place that are costly. That is definitely also a cost-saver with Cloudflare One.

Comprehensive email protection has secured sensitive communications and simplified threat management

Hornetsecurity 365 Total Protection is a good product right now, and the report is available in Spanish, which is beneficial for Latin Americans who speak Spanish. They can continue to improve the pricing because it is the most important aspect, as another solution is aggressive with a lower cost and includes everything. While Hornetsecurity 365 Total Protection is good right now, it would be better to improve the price. At the end, the client sees the price, and in Puerto Rico, the market is different than in the United States since here the client sees price independent of security. I have more effort to explain the difference between price versus technology, which is important because in Latin America, the price may not be the same as in the US due to the company's increase not being the same volume. When clients have many mailboxes, the price is more important than the technology. I do not know why, but this really happens.

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.

Pros

"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."

"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."

"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."

"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."

"Cloudflare is simple to use."

"It will take the blow rather than our applications should an attack occur."

"It is a stable solution."

"Cloudflare Access is part of the Zero Trust philosophy."

More Cloudflare One pros

"Hornetsecurity 365 Total Protection is an easy-to-use solution."

Cons

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

"Operating and tuning the product is difficult."

"Our customers no longer use Cloudflare because its service is subpar."

"Our subscription plan for the solution has a limitation of bot signatures."

"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 initial onboarding was causing us some confusion."

"I would like them to include a VPN feature to provide a secure connection to the data center."

"Feedback could be enhanced."

More Cloudflare One cons

"A reduction of 10% in pricing can be an improvement."

"The pricing is a little high compared to other products."

"The solution’s pricing is not reasonable."

"They can continue to improve the pricing because it is the most important aspect, as another solution is aggressive with a lower cost and includes everything."

"I guess I would say maybe quick access to training material for end-users. I know partners have access to this but I as an end-user do not have immediate access to new update information."

"I guess I would say maybe quick access to training material for end-users."

"We still see many false positives from time to time with Microsoft Defender for Office 365, so it would be good if we can reduce those false positives and provide better workflows for our end users, as sometimes they may not know what to do when they encounter a false positive."

"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."

"If I could improve anything, I would reduce the cost."

"The UI needs to be more user-friendly."

"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."

"The custom alerts have to improve a lot."

"I think that Microsoft Defender for Office 365 could be improved if it could use VirusTotal to compare the programs or anything that I download."

"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
