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Outdated user-interface and offers basic functionality, they have great marketing but only deliver the basics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

"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."
"Cloudflare is simple to use."
"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 Zero Trust Platform removes the risk of exposing the applications to the public."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"I'm very satisfied with the environment and the dashboard."
"The solution has different options that can be used to differentiate DDoS attacks."
"Cloudflare is by far the most effective solution that I have come across."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"With Defender for Office 365, we have been able to increase the security posture across our organization."
"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 Defender for Office 365's most valuable feature is its performance."
"The most valuable feature is the integration; it's a single console, so we don't have to switch around between multiple products, and another valuable feature is the ease of operations and maintenance."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"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."
"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."
"We have absolutely seen ROI, as the regained productivity hours that we were able to claim since we automated the email protection have been really good, and our team of three people has seen an increase in our productivity by around 30% since implementing SpamTitan."
"The encryption feature seems to be the most useful. We didn't have a convenient option for it previously, and having the capability to encrypt from within the message nearly seamlessly is a benefit to us."
"The price of this solution is low."
"We have absolutely seen ROI. The regained productivity hours that we were able to claim since we automated the email protection have been really good. Our team of three people has seen an increase in our productivity, by around 30%, since implementing SpamTitan."
"So far, SpamTitan is the easiest and most efficient solution I've used."
"Within the first two weeks of the trial, I said, "Let's buy it," because it was that great and worked that well for us."
"It's overwhelmingly beneficial just as a general-purpose mail filter."
"In some ways, it was nice SonicWall did fail because we have a better solution now."
 

Cons

"Cloudflare DDoS has poor technical support."
"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."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"They don't have a person to provide support for customers using the solution under their free plan."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Feedback could be enhanced."
"Operating and tuning the product is difficult."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"The visibility for the weaknesses in the system and unauthorized access can be improved."
"There's room for improvement regarding the time frame for retrieving emails."
"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."
"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."
"In the areas of improvement for Microsoft Defender for Office 365, the console is the biggest challenge for me."
"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"Specifying your own filtering rules can be somewhat tricky. You can leave it alone or add your own filter rules using regular expressions. It would be nice to get a little more help configuring the regular expressions. That is quite complicated, and it's something I struggled with."
"The product's GUI, dashboard, and speed could be better."
"Some of the menus on the dashboard could be easier to navigate. It takes a little while to find things."
"We would like to improve the number of quarantine reports received per day. At the moment, only one is received within 24 hours. So, there are a number of complaints that we get from customers who want to improve the reporting of the quarantined emails since they only get one copy per day. This means they may not receive other emails that have been received after they get the report. So, we would like SpamTitan to improve on the frequency of the quarantine report."
"The user interface of SpamTitan is fair, at best. They're coming out with a new one. The current one is a bit hard to navigate, and that was the biggest part of what made it a steep learning curve. It took three to six months to learn how to find stuff in there."
"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."
"The documentation for how to configure it could be better. Sometimes, it was confusing. When we were onboarding with them, the documentation was a little bit vague on how to configure the DNS server and our email server."
"The interface needs to be improved; some elements aren't where I expect them to be, so it could be more intuitive."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"The prices are slightly expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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 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 solution's pricing lacks transparency."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"The pricing has become expensive."
"The license is expensive because the cost is based on the number of users."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"I know that the product is incredibly expensive."
"But the most critical factor was cost-effectiveness. SpamTitan was much cheaper than Barracuda and offered the same value."
"Pricing is on par with other products, and it's reasonable."
"The pricing is just right."
"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."
"The product's cost is average."
"Partner profitability is good with Titan HQ's partner program. This means that I recommend it to clients who trust me. My time and effort to educate them is compensated by TitanHQ, who provides the solution to me at a lower price than what the public gets it at, then I can make some money."
"The pricing is very reasonable. I know the cloud version costs more because of active 24/7 monitoring, but we take care of that as our setup is on-prem. SpamTitan is in line with what we were paying for GFI MailEssentials but works much better."
"I don't deal with pricing. In terms of licensing, the last I heard was that the licensing for users in SpamTitan isn't fully functioning because of some integration issues with Microsoft. I know we have more than 20% on our licensing at the moment, but the way the licensing is supposed to run makes a lot of sense for us. We are looking forward to that part getting implemented correctly."
