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Outdated user-interface and offers basic functionality, they have great marketing but only deliver the basics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 will take the blow rather than our applications should an attack occur."
"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."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"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."
"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 Access is part of the Zero Trust philosophy."
"Cloudflare is by far the most effective solution that I have come across."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"Defender for Office 365 has helped eliminate having to look at multiple dashboards and that is the aspect I like most about it. It is simpler, effective, and convenient. The users like the process efficiency."
"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"Microsoft Defender for Office 365 is a stable solution."
"The good part is that you don't have to configure it, which is very convenient."
"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 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."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"It is a very easy product to use. There is one interface that services all our clients' health. Once learning the interface, we don't have to learn another one for each client. It is the same interface, which is valuable. Therefore, we find the single interface the most valuable since I have a very small team. I don't have one or two people dedicated to just SpamTitan. We all need to learn the interface and be fluent in it. So, having a unified single interface is a big deal for us. I don't have to teach my people five different interfaces in order to be managing a product. They use one interface for all our clients. It is a single pane of glass, which is huge for us."
"It filters some of the spam."
"SpamTitan is an excellent product; the only issue is with the UI, which is somewhat dated."
"This sounds hyperbolic, but it's easily the best purchase that I've made since I started this business, 15 or 16 years ago."
"Every client that uses it experiences a productivity boost. If somebody has to filter through 150 or 200 emails a day to find the 30 good ones, that's inefficient. If they're using SpamTitan it's making them more efficient because they don't have to go through all the junk."
"It lowers the amount of junk email you have to go through and delete."
"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."
"The most valuable features of TitanHQ SpamTitan are how effective it is and how little maintenance it requires."
 

Cons

"Feedback could be enhanced."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"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."
"For the topic of improvement, providing some training material is one of my suggestions."
"The response time for support must be reduced."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published."
"The custom alerts have to improve a lot."
"The pre-sales cost calculations could be more transparent."
"I'd like some additional features any product can give me to protect our environment in a better way."
"There needs to be an improvement in having the product work across multiple operating systems and have better support for non-Microsoft file types."
"One area for improvement is integration. For example, when it comes to external SaaS platforms, we were not able to get a lot of information on integrations with such apps for security and authentication."
"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."
"There should probably be a little more explanation on why one day, the email from one company goes into quarantine, and the next day, it doesn't. To me, it is a little bit random at times."
"The user interface is good, but it could use some improvement. There's a little bit of an issue where a certain feature is not in an intuitive spot and coexisting with another feature that has similar functionality... The UI is a little dated-looking as well."
"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 documentation for how to configure it could be better. Sometimes, it was confusing."
"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."
"Sometimes, things can get caught back in spam that you had previously released."
"We're so used to it now. If anything, there should be more ease of access for the users. If you're on our mail server, there should be easier access for you to better manage your own mailbox."
 

Pricing and Cost Advice

"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 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's pricing lacks transparency."
"Cloudflare Zero Trust Platform's pricing is good."
"The prices are slightly expensive."
"The solution is not that expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The product is very expensive."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"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 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."
"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."
"The pricing is normal. Considering its popularity, it's not overpriced."
"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."
"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."
"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."
"Everything has really been great with the pricing and licensing. In fact, we just implemented ArcTitan because everything was going so well with SpamTitan."
"The pricing is very reasonable and very comparable in the industry... Their licensing structure does leave a little bit to be desired. I would like it to be easier to understand how I can add licenses and update things."
"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."
"It's not extremely expensive. Other solutions get really pricey, really fast."
"Cloud-based solutions charge per mailbox, which isn't ideal sometimes. A company could have 300 total mailboxes and only 50 in regular use, but they would have to pay the same for all of them. I want a cloud-based solution that gives a price based on the volume of email traffic."
