CV
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.
Ricky Brewster - PeerSpot reviewer
Helpdesk Internal Systems Manager at Active IT Systems
Delivers reliable email security with minimal maintenance and valuable threat intelligence
If you had asked me a few weeks ago, I would have said the user interface needed improvement, but we've just updated it. It looks really modern now, and it's a lot easier to use. At the moment, I don't have anything specific for improvement. Additionally, I would suggest different roles for users. We want the ability to lock down certain functions for certain user roles to prevent accidental changes, such as an apprentice accidentally deleting a customer.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"Cloudflare is by far the most effective solution that I have come across."
"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 DDoS mitigates DDoS attacks."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"I'm very satisfied with the environment and the dashboard."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"Scalability-wise, I do not think there are any issues so far."
"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."
"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."
"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."
"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."
"Technical support is very good. They are knowledgeable and respond quickly."
"We saw the benefits the same day that we deployed it, reducing spam emails from between 300 and 600 a day to 15 on the first day and cutting employees' time spent sifting through emails from about two hours a day to just two to three minutes."
"SpamTitan is an excellent product; the only issue is with the UI, which is somewhat dated."
"SpamTitan is extremely easy to learn and use."
"This sounds hyperbolic, but it's easily the best purchase that I've made since I started this business, 15 or 16 years ago."
"The most valuable feature is the Link Lock, which prevents our users from clicking on links that haven't been verified."
"Previously, we were getting too much junk mail in the inbox, and now it gives us more time to focus on work rather than deleting emails."
"In some ways, it was nice SonicWall did fail because we have a better solution now."
"I would highly recommend this solution to others."
 

Cons

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"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."
"Feedback could be enhanced."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"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."
"For the topic of improvement, providing some training material is one of my suggestions."
"Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"We are waiting for better software to block viruses."
"You should be able to deploy Defender for every subscription without the need to add servers."
"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."
"The phishing and spam filters could use some improvement."
"The pre-sales cost calculations could be more transparent."
"We had problems initially when first implementing eFaxing. We had problems trying to get eFaxes to be recorded correctly and come through correctly."
"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. They need an API for Office 365 which is currently being developed"
"There is no plugin for Outlook, which might be of an advantage so that you can just click on a link in Outlook that takes you right to your quarantine list. It doesn't have that at the moment."
"The only downside is that there is a delay when we're waiting for a report to be generated."
"The admin user interface is very granular. Anyone who is in IT can relate to the statement: "With anything granular, there is going to be a little bit of complexity." It can be difficult, on a layer-by-layer basis, to wrap your head around it. Because the administration interface is so granular, some of the categories and some of the settings end up in really odd places. It's hard to figure out where a certain setting is sometimes."
"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."
"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."
"As a Danish company, it would be great to see a Danish translation for the UI."
 

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 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 prices are slightly expensive."
"The solution is not that expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution's pricing lacks transparency."
"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."
"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."
"It's a user-base subscription."
"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."
"The license is expensive because the cost is based on the number of users."
"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."
"Compared to all of the others, including the solution we used previously, SpamTitan is cheaper."
"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 reason that they can be so reasonable with their cost is that they don't have to spend a lot on support. It's such a stable product that you're not needing to contact them that much. If their customers don't need to call support every other day, they can give them a solution that is cost-effective."
"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."
"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."
"It is very good. We actually ended up saving money from our previous solution."
"Price-wise, this product is very compatible with our budget."
