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Outdated user-interface and offers basic functionality, they have great marketing but only deliver the basics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

"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 DDoS mitigates DDoS attacks."
"This solution is easy to understand and easy to configure."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare is simple to use."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"The blocking feature is very good."
"The feature of Microsoft Defender for Office 365 that I like the most is probably the email features specifically, because those are the ones that a typical end user will accidentally click on a link not knowing what it is, and it'll catch it, and then it'll feed it over to Defender and stop the attack from happening before it actually can."
"The features I appreciate most about Microsoft Defender for Office 365 are admin notifications for potential threats along with protecting our Microsoft apps such as Outlook from potential phishing attacks."
"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."
"Technical support is very good. They are knowledgeable and respond quickly."
"The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"The most valuable feature is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."
"The ability to respond to threats if very important."
"SpamTitan has helped improve our spam catch rate and reduce our false positive rate by at least 70%; if we are tracking viral intrusions, it is even more than that, as it has virtually eliminated viral intrusions."
"The fact that it does exactly what it says on the box is what I find most valuable about SpamTitan. They've reduced our spam by about 99 percent."
"The granularity of the setup is most valuable; it has all the features we need from global settings to per-user settings, which makes it possible to really fine tune the spam filter and we are pretty happy with it."
"Overall, the intuitiveness of this product is pretty good."
"If it blocks one piece of malware from getting into my system, it has probably paid for itself several times over."
"SpamTitan is used for spam protection, nothing else; that's what it does, and it does it well."
"It works as it should. It allows users to manage emails that they receive, meaning they can set up whitelists and blacklists."
"I'd advise any new users to just sign up. Just don't even bother considering it, just sign up and go with it. You won't regret it. Its ease of use, ease of setup, and ease of admin all make it worthwhile. Everything is just so easy."
 

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 initial onboarding was causing us some confusion."
"The initial onboarding was causing us some confusion."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Cloudflare DDoS has poor technical support."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Our subscription plan for the solution has a limitation of bot signatures."
"Feedback could be enhanced."
"There is a different console for different things; I just want one consolidated console."
"Several simulation options are available within 365, and the phishing simulation could be better."
"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
"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."
"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."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"Sometimes I have to recategorize things when it takes the wrong step and I do not want it to classify something as suspicious."
"Microsoft Defender for Office 365 is not up to the mark in comparison with Wiz or Palo Alto."
"The analysis of ransomware attachments could be improved. Other solutions seem to detect ransomware faster than SpamTitan does."
"The way it rates what is spam and what is not spam can be improved, although that is true with every system."
"I'm not 100% sure how well they scan certain attachments."
"The stability of SpamTitan is equivalent to other email security solutions that I have previously used. Some of them have more bells and whistles that you can add."
"Thousands of our customers really don't like the reports; they can't fine-tune or adjust when they get delivered."
"SpamTitan doesn't quarantine when it blocks things based on the remote block list or greylisting. It just deletes the email. When I try to look at these blocked items, it tells me they're gone. RBL or greylisted items aren't saved, so you can check them. There may be a setting somewhere that I haven't seen."
"Its GUI can definitely be improved. As the administrator of the product, the GUI isn't very logically built. If you need something, you don't have one menu where you can say, "Well, this relates to our customers," and manage everything for your customers in that interface. The naming and placement of some of the menus need improvement. For example, if I'm looking for a log to take a look at what has passed through the filter of a specific customer, I get these ZIP-packed files that I can't use for anything. I have to look under history instead. The naming of some of the features is off by a lot."
"I'd like to see something like "My First SpamTitan," by which I mean, "Guide me through the things I need to set, and tell me about the things that you're setting already.""
 

Pricing and Cost Advice

"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 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 prices are slightly expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution is not that expensive."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"The product is expensive."
"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"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."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"It's a user-base subscription."
"Compared to the market, its price is fair."
"Its pricing is good. We've been happy with the pricing. I know that they did some extensive research, and the pricing was quite favorable with everything else that they looked at. My budget hasn't changed a whole lot over the last three to five years. It's nice to see that it has remained pretty steady. So, I am happy with the pricing. It provides good value for money."
"I pay $650 per year for 50 licenses."
"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 product's cost is average."
"The pricing was a little bit below the average of what we were looking at."
"The cluster was an additional cost. We had to get some more licenses to get to that level. It's well worth it because it means peace of mind for everyone."
"When it comes to the scalability of it, it really doesn't matter much because of the way that it is priced. You can put it on somebody who is small or big."
