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

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 Access is a stable solution."
"Cloudflare Access is part of the Zero Trust philosophy."
"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."
"It is a stable solution."
"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 simple to use."
"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 Zero Trust Platform removes the risk of exposing the applications to the public."
"The technical support is good and quick to resolve issues."
"Microsoft Defender for Office 365 has improved my organization's security. It makes it easier to manage the infrastructure without the help of third-party applications."
"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."
"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 ability to respond to threats if very important."
"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."
"The deployment capability is a great feature, and we're able to activate this feature throughout France with a click."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"We have had no cases of malware slipping through since we have had SpamTitan."
"We really like the fact that we get a quarantine report because we can identify for ourselves which emails we want to keep and which we want to get rid of. It also gives us the option of directly allowing emails, which we really like. That way, the next time we get such emails, they're not blocked."
"They have never let us down and we have never looked back."
"We haven't had any virus infections since implementing SpamTitan."
"The way we can customize filters is excellent. Other solutions tend to be restrictive with their specific profiles, but with SpamTitan, we can create them from scratch."
"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."
"If all you have is a solution that looks at every piece of email and applies the same types of rules, you don't get a very smart solution. Whereas, if you can do it per mailbox or per domain, like you can with SpamTitan, that means you are effectively able to configure it almost per-user, which is great."
"SpamTitan has absolutely helped to improve our spam catch rate, as well as our false positive rate."
 

Cons

"The response time for support must be reduced."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"They don't have a person to provide support for customers using the solution under their free plan."
"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."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"The initial onboarding was causing us some confusion."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"I'd like some additional features any product can give me to protect our environment in a better way."
"This is quite an expensive solution and understanding the pricing model and features is quite complicated and it can, in fact, be a nightmare when dealing with Microsoft."
"Its price should be improved. Its cost is a major concern for us."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"Microsoft Defender for Office 365 is not up to the mark in comparison with Wiz or Palo Alto."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"The custom alerts have to improve a lot."
"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 overall GUI is utilitarian. It has a spreadsheet feel versus a nice software that is guided. I am sure they're going to improve it over time. It could look a little prettier. It needs some lipstick. They should get rid of unfamiliar words like ham and spam, helping the user to better understand what they are clicking through."
"The setup was a little difficult, but they did have people who helped me so I eventually got there. They had a change and my IT people had to do some stuff. There was something about pointers. I don't remember the details where we had a little trouble, but they were changing some things around."
"Some of the menus on the dashboard could be easier to navigate. It takes a little while to find things."
"I wish there would be less false positives."
"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."
"Sometimes, things can get caught back in spam that you had previously released. Without going in, releasing the whole domain, and opening it up, since you don't want to do that often because the company can get infected as well, I have a couple of things that I previously released show back up again. I don't understand why this is happening, but I would like to know why it happened, e.g., did an algorithm change? It is important to know if I released an email last week why it was caught in spam the following week."
"It took some adjustment and some getting used to when it came to where to add the users and the general layout. It wasn't very logical or intuitive. That functionality was under the Anti-Spam Engine instead of Domain or User Policies."
 

Pricing and Cost Advice

"The prices are slightly expensive."
"The solution's pricing lacks transparency."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution is not that 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."
"Cloudflare Zero Trust Platform's pricing is good."
"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 normal. Considering its popularity, it's not overpriced."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"The product is expensive."
"It's a user-base subscription."
"The pricing has become expensive."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"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."
"It's not extremely expensive. Other solutions get really pricey, really fast."
"The price of SpamTitan is reasonable. It makes sense. There is no cost for me because I'm the managed service provider. The end customer pays the cost because we sell professional services to set up the whole solution, including SpamTitan and other products. Usually, it's part of a much bigger project."
"The price was great compared to other solutions that we looked at the time."
"Everything has really been great with the pricing and licensing. In fact, we just implemented ArcTitan because everything was going so well with SpamTitan."
"But the most critical factor was cost-effectiveness. SpamTitan was much cheaper than Barracuda and offered the same value."
"We're happy with their licensing model. It was a major factor in why we chose them."
"The pricing was a little bit below the average of what we were looking at."
