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Outdated user-interface and offers basic functionality, they have great marketing but only deliver the basics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

"Enables me to work from two locations."
"Cloudflare, in my opinion, was easy to implement."
"I'm very satisfied with the environment and the dashboard."
"This solution is easy to understand and easy to configure."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare DDoS mitigates DDoS attacks."
"The blocking feature is very good."
"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."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"Manual email investigation and remediation effort was reduced by roughly 40 to 50 percent because of automated investigations, quarantine, and post-delivery remediation."
"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 of Microsoft Defender for Office 365 is the ease of use."
"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."
"The product's scalability is good."
"Scalability-wise, I do not think there are any issues so far."
"The coolest feature of Microsoft Defender for Office 365 is its ability to look for phishing emails."
"SpamTitan is used for spam protection, nothing else; that's what it does, and it does it well."
"The most valuable features of TitanHQ SpamTitan are how effective it is and how little maintenance it requires."
"SpamTitan learned faster than I thought it was going to, based on other products that I've used. There was a lot more feedback. The other products are based on the users, but this one, with its AI, seems to produce tremendous improvements day-to-day. I told the teams it was going to take two to three weeks but, within a week, we had dropped the amount of spam that was getting through."
"It is very simple to use. For our client, we set it up as a cluster. That is one of the benefits. You can eliminate single points of failure. We use it in a cluster in the environment where there are two gateways. Thus, if one fails, the other one keeps taking over without any disruption."
"I would highly recommend this solution to others."
"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 key differentiator of TitanHQ for its partners is the Sandboxing Service. The email filtering will open up any attachments and run them through two antivirus sandboxes before they reach you. You can pretty much guarantee there's not going to be a virus in them. I've not seen anyone else do that."
"SpamTitan is perfectly suited for managed service providers. It's easy to use and sell. It's also straightforward to configure and monitor. In my opinion, software developers at TitanHQ did an excellent job with SpamTitan."
 

Cons

"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"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 onboarding process can be improved a little bit."
"Our customers no longer use Cloudflare because its service is subpar."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"Its price should be improved. Its cost is a major concern for us."
"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."
"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."
"Several simulation options are available within 365, and the phishing simulation could be better."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"There is a different console for different things; I just want one consolidated console."
"The phishing rate of SpamTitan is not great, even Exchange Online Protection catches phishing better than SpamTitan."
"I would also like to see SpamTitan improve on its antivirus software. A problem with them is that they sometimes miss Trojans and malicious sites."
"The big issue that I've had is that the length of time that an email is kept in quarantine is only seven days and, in some cases, it is not even seven days."
"The big issue that I've had is that the length of time that an email is kept in quarantine is only seven days and, in some cases, it is not even seven days... if I had a 20-day or 30-day repository, if someone came to me and said, "Hey, I can't get this back," I could end up getting it to them from the archive."
"The setup was a little difficult, but they did have people who helped me so I eventually got there."
"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."
"With SpamTitan, the false positives and false negatives seem to be higher than those with the product we had previously. The other area for improvement has to do with how to deal with false positives. If something slips through, there's no easy way to mark it as spam globally. The add-in has not been working. We haven't even deployed it to our entire organization yet because it's not working for the few in the pilot project."
"SpamTitan is not particularly configurable. I basically have to accept their parameters for a lot of things."
 

Pricing and Cost Advice

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution is not that expensive."
"The prices are slightly expensive."
"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."
"I know that the product is incredibly expensive."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"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."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"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 is much more expensive than using another solution because we have had to include some options and upgrade our license."
"It's priced very reasonably. There are no additional licensing costs that affect me."
"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 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."
"As a small business, every penny is counted here... I really thought that something like SpamTitan would be more expensive, but it cost me about $70 (or about £60) a month. I'm more than happy to pay that."
"It's a very good product and the pricing and licensing are exceptionally reasonable."
"They have different packages, services, or products that they sell. I would recommend it for small businesses to larger organizations, even enterprises, but not individuals."
"The pricing was much more competitive than other solutions, so I was like, "Okay, let's give it a try.""
"Its pricing is good. It's probably one of the most competitive anti-spam and anti-malware appliances out there for email. I was doing some looking around for pricing before I came to SpamTitan, and for the feature set, the price is very reasonable and competitive."
