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Outdated user-interface and offers basic functionality, they have great marketing but only deliver the basics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

Pros

"Cloudflare is simple to use."
"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."
"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."
"This solution is easy to understand and easy to configure."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"It is a stable solution."
"Cloudflare is simple to use."
"Cloudflare Access is a stable solution."
"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."
"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."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"The feature I like the most about Microsoft Defender for Office 365 is that it typically runs in the background—you do not know it is there until you need to access it."
"Microsoft Defender for Office 365 has decreased my time to detection and time to respond by one hundred percent."
"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."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"I have found the feature that creates seamless categorization of emails valuable. This is most likely done by having a large database to compare and to identify what are the domains that are currently spammers."
"We like to stick with SpamTitan for anti-spam, because it gives us the least problems and less false positives compared to other solutions."
"SpamTitan has helped us big time with improving our spam catch rate and reduced our false positive rate."
"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."
"The user interface for regular users is quite intuitive. The email report that they receive is pretty self-explanatory. The online interface for administrators is simple yet really quite effective. It's really a set-it-and-forget-it, and everything is available when needed."
"SpamTitan is an excellent product; the only issue is with the UI, which is somewhat dated."
"Since we started using SpamTitan we've received some 22 million email messages and it has filtered out about 28 percent of all emails before they even got to a user."
"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

"Our customers no longer use Cloudflare because its service is subpar."
"They don't have a person to provide support for customers using the solution under their free plan."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"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."
"Operating and tuning the product is difficult."
"The initial onboarding was causing us some confusion."
"The response time for support must be reduced."
"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."
"From a development point of view, if I wanted to do development on my actual machine where Defender is, the organization can set certain policies or Defender makes that prohibitive."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"I think Microsoft Defender for Office 365 can be improved by creating more educational pieces about not just looking for malware."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published."
"This is quite an expensive solution and understanding the pricing model and features is quite complicated and it can, in fact, be a nightmare when dealing with Microsoft."
"The GUI is sometimes slow to fetch the device report and could be improved."
"It's been the same interface for ten years and some things are hard to find, even after using it for years."
"We had problems initially when first implementing eFaxing. We had problems trying to get eFaxes to be recorded correctly and come through correctly."
"There is room for improvement in automation; better wizards for deployment, for example."
"False positives may be an area for improvement. It's very rare that we see false negatives, but false positives might be an area where I, myself, could put some more effort into looking at the settings... Perhaps that's something in the user interface that isn't hugely clear."
"The phishing rate of SpamTitan is not great, even Exchange Online Protection catches phishing better than SpamTitan."
"They need to keep up with the latest technology and add new features as they arise, e.g., artificial intelligence, new and improved updated lists, or new ways of tracking spam."
"What would be helpful to me is an alert if there were an increase in the number of threats that have been picked up."
"SpamTitan's logging features could be improved. The logs are hard to deal with because you need to download the log as a text file. Then you need to search through this text file to find what you need."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"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 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 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."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"The pricing is normal. Considering its popularity, it's not overpriced."
"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."
"The product is expensive."
"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."
"It's a user-base subscription."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"SpamTitan has competitive pricing and flexible licensing. They allow up to 10% more that you use and then add it to the next tier of licenses."
"The price point is still of a reasonable nature. It is reasonable for the services that they offer. They are very reasonable, and that is one of the factors why we decided on SpamTitan a long time ago."
"The pricing and licensing are acceptable. The licensing is somewhat different; TitanHQ gives us a peak cap of simultaneous users, which they calculate as the number of email addresses viewed through so many days or weeks. That's considered our number of users, but it isn't always a one-to-one relationship, making it harder to resell. We can't say precisely that the solution costs X per month per user, but that's how we present the price to potential customers, and we just ensure we receive more than we pay to TitanHQ. The licensing hasn't caused us any problems, but it would be better if the pricing were per-user. I know that's not easy to achieve on a technical level."
"We pay for licenses and the price structure is very clean. You don't have to pay for on-premises equipment and perhaps a monthly service fee for hardware."
"Compared to all of the others, including the solution we used previously, SpamTitan is cheaper."
"The price of this solution is low. When you do purchase everything is included in the licensing cost."
"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 price is good by today's standards. You actually get what you pay for."
