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.

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.

Pros

"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."
"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."
"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."
"Clover is the best product globally."
"The best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"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 by far the most effective solution that I have come across."
"This solution is easy to understand and easy to configure."
"The initial setup was easy."
"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 basic features are okay and I'm satisfied with the Defender."
"One of our clients didn't have the budget to invest in a SOC team, but we deployed the solution for them, and they now run a SOC with only one analyst."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"The technical support is good and quick to resolve issues."
"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."
"Does a thorough job of examining email and URLs for malicious content."
"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."
"From a price-performance ratio, it is one of the best; it does not cost a lot and does its job just fine, and if you fine tune it, it is just ideal."
"If it blocks one piece of malware from getting into my system, it has probably paid for itself several times over."
"I like the notifications SpamTitan sends. Other products require the user to log into the system to see if something was blocked. SpamTitan sends users an email showing them any potential spam that was blocked and they can click on it to release it. It's much easier for the end-user."
"I like the ability to go online and view mail that's been quarantined. SpamTitan lets you look at the mail and decide whether you want to release it or not."
"I would recommend at least checking out SpamTitan because it has been really good for me."
"If it can stop all the garbage from getting through, then it is definitely a time saver. It is more protecting our employees than anything. We just want to make sure that we can do everything that we can do to try and prevent people from clicking on bad stuff or having to deal with bad stuff. It is easier to prevent it from coming into the network."
"The user interface for regular users is quite intuitive. The email report that they receive is pretty self-explanatory. The online interface for administrators is simple yet really quite effective. It's really a set-it-and-forget-it, and everything is available when needed."
 

Cons

"Cloudflare DDoS has poor technical support."
"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."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The response time for support must be reduced."
"Operating and tuning the product is difficult."
"For the topic of improvement, providing some training material is one of my suggestions."
"The initial onboarding was causing us some confusion."
"The initial onboarding was causing us some confusion."
"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."
"The custom alerts have to improve a lot."
"There needs to be an improvement in having the product work across multiple operating systems and have better support for non-Microsoft file types."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"The custom alerts have to improve a lot."
"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."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"The SpamTitan user interface is not amazing, but I don't mind it. I know they are releasing a new one soon. I have seen it and it looks a lot better. That has been an area that needs improvement."
"False positives may be an area for improvement. Perhaps that's something in the user interface that isn't hugely clear."
"As a Danish company, it would be great to see a Danish translation for the UI."
"When an email is quarantined, there are a couple of different search filters to help find what you're looking for. Having more choices would be helpful because as it is now, we can search for inbound or outbound, the score, the subject, and the email address."
"From a small business point of view—we're 30 people—there should be a price break before you have 500 people. Small businesses don't have a lot of money."
"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 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"
"The only improvement that comes to mind is updates."
 

Pricing and Cost Advice

"The solution's pricing lacks transparency."
"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 prices are slightly expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"Cloudflare Zero Trust Platform's pricing is good."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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."
"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 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."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"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."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"Everything has really been great with the pricing and licensing. In fact, we just implemented ArcTitan because everything was going so well with SpamTitan."
"Compared to the market, its price is fair."
"The price is good by today's standards. You actually get what you pay for."
"The pricing for this solution is fair, and comparable with other products."
"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."
"It's not extremely expensive. Other solutions get really pricey, really fast."
"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."
"The pricing was much more competitive than other solutions, so I was like, "Okay, let's give it a try.""
