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.

Quotes from Members

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

Pros

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"The solution has different options that can be used to differentiate DDoS attacks."
"Cloudflare Access is a stable solution."
"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."
"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 best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"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."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"Scalability-wise, I do not think there are any issues so far."
"The stability of Microsoft Defender for Office 365 is fantastic."
"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"The deployment capability is a great feature, and we're able to activate this feature throughout France with a click."
"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."
"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."
"Microsoft Defender for Office 365 has decreased my time to detection and time to respond by one hundred percent."
"Microsoft Defender for Office 365 is a cloud-based email filtering service that helps protect our organization against unknown malware and viruses by providing robust zero-day protection and includes features to safeguard our organization from harmful links in real-time."
"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 used for spam protection, nothing else; that's what it does, and it does it well."
"They have never let us down and we have never looked back."
"The solution works really well. For a small nonprofit like us who don't have a large server footprint and rely heavily on cloud services, this is great for all our emails and the mobile workforce that we have. This is a great way to manage the traffic, hopefully keep our people from getting the phishing emails and stuff like that, helping to mitigate the risks."
"SpamTitan provided all the features that we needed, and it was cost-effective."
"We've seen a 95 percent reduction in inbound spam and an equivalent reduction in inbound, malicious, phishing emails, and virus emails."
"I like that advanced features such as DKIM signing are integrated into SpamTitan. It works well, and setting up DKIM can be cumbersome for many email servers, particularly with Microsoft Exchange. DKIM signing verifies the sender's authenticity by applying a signature to outgoing emails, and it was straightforward to set up within the solution."
"They have something called Pattern Filtering, which has been a godsend... For example, if I don't want any email to ever come through that has the term "hot dog" in it, whether it be in the subject, the title, or anywhere else, I can immediately block such emails, company-wide. That has saved me so much time."
 

Cons

"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"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 initial onboarding was causing us some confusion."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The response time for support must be reduced."
"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."
"The onboarding process can be improved a little bit."
"Cloudflare DDoS has poor technical support."
"We need to be able to whitelist data at the backend."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"I think that Microsoft Defender for Office 365 could be improved if it could use VirusTotal to compare the programs or anything that I download."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"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."
"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."
"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."
"We would like to improve the number of quarantine reports received per day. At the moment, only one is received within 24 hours. So, there are a number of complaints that we get from customers who want to improve the reporting of the quarantined emails since they only get one copy per day. This means they may not receive other emails that have been received after they get the report. So, we would like SpamTitan to improve on the frequency of the quarantine report."
"SpamTitan is not particularly configurable. I basically have to accept their parameters for a lot of things."
"Emails from companies we work with often get flagged, and I have to go in and release them. For example, I made a hotel reservation today from Marriott that got blocked. I'm sure hotels spam people, but I wish there was a way to know that the email was to confirm my reservation and for it to allow that through."
"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."
"If they had a little more documentation explaining how to use regex, or if they could include that inside of the cloud interface so that it generates regex code based on the parameters you input, that would be a lot more useful for people who aren't familiar with coding languages and HTML."
"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 documentation provided is very rudimentary."
"I'm not 100% sure how well they scan certain attachments."
 

Pricing and Cost Advice

"The solution's pricing lacks transparency."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution is not that expensive."
"The prices are slightly expensive."
"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."
"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The pricing has become expensive."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The pricing is normal. Considering its popularity, it's not overpriced."
"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."
"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."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"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."
"I pay $650 per year for 50 licenses."
"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."
"The cluster was an additional cost. We had to get some more licenses to get to that level. It's well worth it because it means peace of mind for everyone."
"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."
"I don't deal with pricing. In terms of licensing, the last I heard was that the licensing for users in SpamTitan isn't fully functioning because of some integration issues with Microsoft. I know we have more than 20% on our licensing at the moment, but the way the licensing is supposed to run makes a lot of sense for us. We are looking forward to that part getting implemented correctly."
"The approximate cost is around $7000 USD."
"The pricing and licensing have been very fair. I can't complain."
"But the most critical factor was cost-effectiveness. SpamTitan was much cheaper than Barracuda and offered the same value."
