CV
Network Architect at IP Dimension
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.

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.
Ricky Brewster - PeerSpot reviewer

Delivers reliable email security with minimal maintenance and valuable threat intelligence
If you had asked me a few weeks ago, I would have said the user interface needed improvement, but we've just updated it. It looks really modern now, and it's a lot easier to use. At the moment, I don't have anything specific for improvement. Additionally, I would suggest different roles for users. We want the ability to lock down certain functions for certain user roles to prevent accidental changes, such as an apprentice accidentally deleting a customer.

Quotes from Members

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

Pros

"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."
"Clover is the best product globally."
"Cloudflare Access is part of the Zero Trust philosophy."
"The solution has different options that can be used to differentiate DDoS attacks."
"It will take the blow rather than our applications should an attack occur."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Cloudflare is simple to use."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
"The deployment capability is a great feature, and we're able to activate this feature throughout France with a click."
"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."
"Defender enables us to secure all 365-related activity from a single place. It gives us visibility into everything happening in Outlook, protecting us against phishing and other email-based threats. Defender helps us detect any suspicious behaviors."
"One of the best features of the tool is its capability to aggregate insights from different workloads, basically from the Office 365 and endpoints part."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"It definitely is a must for email protection and O365 app DLP, and combined with Microsoft Defender for Endpoint, Microsoft Defender for Identity, and MCAS, it provides a holistic solution for threat protection, email protection, O365 apps protection, and DLP for both internal and external risks."
"My experience deploying Microsoft Defender for Office 365 was seamless."
"In summary, this is an awesome system."
"One of the biggest benefits is added security, as email is the primary mode of infection for viruses and SpamTitan helps to protect us in that regard."
"We are satisfied with the performance and spam filtering provided by TitanHQ SpamTitan. The reporting feature and customizations as per our requirements are also good."
"Their superior service comes at a very cost-effective price. This is the biggest part that really allows us to remain competitive. Their pricing for us has just been great. They have helped us to be where we need to be. They really do partner with us in that way so we can get more business. They provide the right pricing, which lets us remain competitive."
"The price of this solution is low."
"I would highly recommend this solution to others."
"It is very simple to use. For our client, we set it up as a cluster. That is one of the benefits. You can eliminate single points of failure. We use it in a cluster in the environment where there are two gateways. Thus, if one fails, the other one keeps taking over without any disruption."
"We like to stick with SpamTitan for anti-spam, because it gives us the least problems and less false positives compared to other solutions."
 

Cons

"Operating and tuning the product is difficult."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"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."
"The initial onboarding was causing us some confusion."
"For the topic of improvement, providing some training material is one of my suggestions."
"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."
"In the areas of improvement for Microsoft Defender for Office 365, the console is the biggest challenge for me."
"We need a separate license and we don't know how to get the license that is required."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published."
"The certification training for Defender for 365 needs to be deeper and incorporate Sentinel. I took all the security courses except one, and Sentinel isn't included."
"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."
"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"I would like to see a filter for searching inside the message content when it is quarantined."
"The way it rates what is spam and what is not spam can be improved, although that is true with every system."
"It could be improved a little bit on the speed side. When I am trying to troubleshoot a mail message that somebody is looking for in SpamTitan, sometimes setting up the filters for the quarantine is a little bit pokey."
"It would be nice if the reporting feature could be updated. Also, the feel of the web interface is a little dated."
"With SpamTitan, the false positives and false negatives seem to be higher than those with the product we had previously. The other area for improvement has to do with how to deal with false positives. If something slips through, there's no easy way to mark it as spam globally. The add-in has not been working. We haven't even deployed it to our entire organization yet because it's not working for the few in the pilot project."
"There is no plugin for Outlook, which might be of an advantage so that you can just click on a link in Outlook that takes you right to your quarantine list. It doesn't have that at the moment."
"The admin user interface is very granular. It can be difficult, on a layer-by-layer basis, to wrap your head around it."
"The solution is very slow, it crashes and we have difficulties getting emails."
 

Pricing and Cost Advice

"The solution is not that expensive."
"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 prices are slightly expensive."
"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 lacks transparency."
"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."
"Cloudflare Zero Trust Platform's pricing is good."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"The pricing has become expensive."
"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."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"The license is expensive because the cost is based on the number of users."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"The product's cost is average."
"The price of SpamTitan is reasonable. It makes sense. There is no cost for me because I'm the managed service provider. The end customer pays the cost because we sell professional services to set up the whole solution, including SpamTitan and other products. Usually, it's part of a much bigger project."
"The pricing is ideal. A lot of other anti-spams are integrated in Exchange, counting technical mailboxes that are not sending any emails outside. So, they are not scanned and only for internal communication. SpamTitan only counts the emails that it scans. This is one of the best licensing models that I saw for anti-spam solutions because it is counting dynamically the number of emails that senders are sending. It counts these uniquely by week. It provides a very realistic picture. This is very useful because we are not counting the emails doing inbound or outbound notifications from our company."
"The pricing was much more competitive than other solutions, so I was like, "Okay, let's give it a try.""
"The pricing is great, but it has been increasing on a yearly basis. It is now close to that of Microsoft solutions. If it continues to increase, then clients may need to migrate to a different solution."
"It is very good. We actually ended up saving money from our previous solution."
"For the service, the pricing is reasonable."
"This pricing is absolutely fine and it's never been an issue of it being too expensive."
