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.

Outdated user-interface and offers basic functionality, they have great marketing but only deliver the basics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

"Cloudflare is simple to use."
"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"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."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare DDoS mitigates DDoS attacks."
"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"It is a stable solution."
"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."
"The basic features are okay and I'm satisfied with the Defender."
"The DLP feature of Microsoft Defender for Office 365 is valuable, and we also use the DLP feature for email real-time detection."
"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."
"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."
"The email protection is excellent, especially in terms of anti-phishing policies."
"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
"The initial setup was easy."
"The coolest feature of Microsoft Defender for Office 365 is its ability to look for phishing emails."
"The initial setup was relatively easy."
"When we bought this solution, we were looking for 100% security, and it provides that."
"The key differentiators of the product for an MSP are its ease of use and effectiveness. It generates reports and makes things easy for IT to manage. It's a set-it-and-forget-it type of solution."
"The overall system is straightforward to use, and the UI is excellent. It significantly streamlines the process of dealing with spam emails."
"They also let you customize it to match your organization's feel, so it looks like a product from your organization. I like when companies do that. Our city logo is on it when you log in to this system."
"The AI technology is improving email security by enhancing spam detection capabilities."
"I had server issues but I still needed to be able to look at what emails I would have received if my email server had been working correctly. SpamTitan has a reporting functionality that showed me what emails would have been sent. I could actually see the content of those emails."
"SpamTitan is a product that saves us time. The less spam that you have, the more time you have because you're not digging through the mail that hits your inbox."
 

Cons

"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"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."
"For the topic of improvement, providing some training material is one of my suggestions."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The onboarding process can be improved a little bit."
"Our subscription plan for the solution has a limitation of bot signatures."
"There needs to be an improvement in having the product work across multiple operating systems and have better support for non-Microsoft file types."
"The visibility for the weaknesses in the system and unauthorized access can be improved."
"The product must provide better malware detection."
"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."
"Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published."
"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."
"You should be able to deploy Defender for every subscription without the need to add servers."
"There's room for improvement regarding the time frame for retrieving emails."
"We had problems initially when first implementing eFaxing. We had problems trying to get eFaxes to be recorded correctly and come through correctly."
"The solution is very slow, it crashes and we have difficulties getting emails."
"A lot of the other companies that I deal with have a feature that allows you to modify emails and apply signatures automatically based on linking into Azure's servers and database. That feature isn't there in SpamTitan."
"When in the control panel, the context menu that appears when you right-click on an email should present options for adding the sender to the whitelist or blocking them."
"The documentation provided is very rudimentary."
"The only downside is that there is a delay when we're waiting for a report to be generated."
"The interface looks a little dated and could be modernized."
"The admin management portal needs a facelift. I've asked them for a way to authenticate admins of the organizations that want to admin the SpamTitan product itself. Adding additional management security would be a great feature. There are a few tiny improvements they could also make. For instance, the GUI itself is a little outdated, and it could be more user friendly. The same goes for ArcTitan. It's got a horrible GUI that's worse than SpamTitan. It also could use that authentication mechanism upgrade as well. I would also suggest combining the two products into one control panel. ."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"The prices are slightly expensive."
"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 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's pricing lacks transparency."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"The product is expensive."
"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."
"The product is very 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."
"The license is expensive because the cost is based on the number of users."
"This pricing is absolutely fine and it's never been an issue of it being too expensive."
"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 of SpamTitan is about right. It's not over-priced per user. It's not super cheap either, but it is a very good product..."
"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."
"The price was great compared to other solutions that we looked at the time."
"The product's cost is average."
"We're satisfied with the pricing and licensing for SpamTitan."
"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."
