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.

Outdated user-interface and offers basic functionality, they have great marketing but only deliver the basics
I was previously a satisfied customer of OnlyMyEmail. Unfortunately, they had a significant technical failure and couldn't provide security for a week, causing them to lose their biggest client. That's when I switched to Bitdefender for email security. I used Bitdefender. But it didn't meet my needs. I used it for two years. Its technology was far inferior to OnlyMyEmail. I also looked into Censornet. However, I eventually obtained a server license for SpamTitan. Currently, I am one of the slightly happy. customer of SpamTitan. It works when it wants to, it doesn't want, it doesn't work. The main difference between SpamTitan and OnlyMyEmail was accuracy. I never saw false positives with OnlyMyEmail in the ten years I used it. It just worked as it should, and at a very low price. I'm not sure what technology they used, but it was excellent. I was paying around one dollar and something cents per email address per month.

Quotes from Members

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

Pros

"I'm very satisfied with the environment and the dashboard."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare is simple to use."
"It will take the blow rather than our applications should an attack occur."
"The solution has different options that can be used to differentiate DDoS attacks."
"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."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"Enables me to work from two locations."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"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."
"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."
"There are several features that I consider valuable."
"The insights provided with Microsoft Defender for Office 365 are helpful because it comes with the E5 license, and by default, we can use a lot of capabilities."
"Microsoft Defender for Office 365 has decreased my time to detection and time to respond by one hundred percent."
"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."
"Microsoft so far has been good; we haven't faced any kind of disruption or anything else, it's a good product and good platform, I must say, and overall it's a good product and good service and we haven't dealt with bugs or glitches."
"Within the first three years, we were able to see that this product has been perfect for our business."
"It is a very easy product to use. There is one interface that services all our clients' health. Once learning the interface, we don't have to learn another one for each client. It is the same interface, which is valuable. Therefore, we find the single interface the most valuable since I have a very small team. I don't have one or two people dedicated to just SpamTitan. We all need to learn the interface and be fluent in it. So, having a unified single interface is a big deal for us. I don't have to teach my people five different interfaces in order to be managing a product. They use one interface for all our clients. It is a single pane of glass, which is huge for us."
"There was a noticeable improvement in spam in the first week."
"So far, SpamTitan is the easiest and most efficient solution I've used."
"Another good feature, related to geo-blocking, is the ability to specify exemptions. We discovered that some of our customers, even though they are located in Canada, have an Exchange Server sitting in Japan or in the Netherlands. It seems they have branches or their head office in other countries. Having this exception feature is helpful."
"The most valuable feature is the Link Lock, which prevents our users from clicking on links that haven't been verified."
"It has reduced the risk of getting viruses from emails by almost a hundred percent. We are giving services to hundreds of companies, and it makes our work a lot easier when SpamTitan is filtering threats."
"SpamTitan is used for spam protection, nothing else; that's what it does, and it does it well."
 

Cons

"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."
"The response time for support must be reduced."
"Our subscription plan for the solution has a limitation of bot signatures."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Cloudflare DDoS has poor technical support."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"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."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."
"There's room for improvement regarding the time frame for retrieving emails."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"We are always looking for other tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"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 interface looks a little dated and could be modernized."
"The GUI is problematic."
"If I had to actually find a negative, it would be the speed. I wish that the interface were faster. We have very fast internet, but there is definitely some sluggishness between pages on the interface. Does that deter me? No. I just wish it were quicker."
"It would be nice if the reporting feature could be updated. Also, the feel of the web interface is a little dated."
"The inter mailbox email flow needs improvement. If you are in the same domain, it does not have the capability to transfer one email to the same domain through SpamTitan. They need an API for Office 365 which is currently being developed"
"The user interface is good, but it could use some improvement. There's a little bit of an issue where a certain feature is not in an intuitive spot and coexisting with another feature that has similar functionality... The UI is a little dated-looking as well."
"The support hours are tough for U.S.-based companies like ours, because they're in Europe. They did tell me that they're opening a support office in the U.S. There is, currently, some overlap in support, but it's difficult to get real-time support and, a lot of the time, I just need a quick answer."
"Sometimes, things can get caught back in spam that you had previously released. Without going in, releasing the whole domain, and opening it up, since you don't want to do that often because the company can get infected as well, I have a couple of things that I previously released show back up again. I don't understand why this is happening, but I would like to know why it happened, e.g., did an algorithm change? It is important to know if I released an email last week why it was caught in spam the following week."
 

Pricing and Cost Advice

"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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution is not that expensive."
"The prices are slightly 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 solution's pricing lacks transparency."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"Cloudflare Zero Trust Platform's pricing is good."
"The product is very expensive."
"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."
"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."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"Pricing is on par with other products, and it's reasonable."
"It is very good. We actually ended up saving money from our previous solution."
"Our pricing has pretty much stayed somewhat the same. Sure, there has been an increase or two that keeps up with inflation, but that is everybody. When we switched from AppRiver to SpamTitan, we saved about 20%. That is $1,000 to $2,000 a month. We went to SpamTitan and WebTitan. It was $1,000 savings a month for SpamTitan and another $1,500 a month savings for WebTitan."
"The pricing was a little bit below the average of what we were looking at."
"The approximate cost is around $7000 USD."
"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."
"We used to use FortiClient and Symantec Messaging Gateway. We didn't like Symantec's solution, but we switched because of the cost. SpamTitan was more cost-effective than either of the other solutions."
"The price and the licensing are fair, allowing us to make a margin on the product. We paid a one-time fee for the sandboxing feature; apart from that, it's just the standard licensing."
