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

"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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."
"I'm very satisfied with the environment and the dashboard."
"Enables me to work from two locations."
"Cloudflare is simple to use."
"The solution has different options that can be used to differentiate DDoS attacks."
"Cloudflare Access is part of the Zero Trust philosophy."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"Technical support is very good. They are knowledgeable and respond quickly."
"The feature of Microsoft Defender for Office 365 that I like the most is probably the email features specifically, because those are the ones that a typical end user will accidentally click on a link not knowing what it is, and it'll catch it, and then it'll feed it over to Defender and stop the attack from happening before it actually can."
"The product is not resource-intensive."
"The stability of Microsoft Defender for Office 365 is fantastic."
"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"The technical support is good and quick to resolve issues."
"The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not."
"When we bought this solution, we were looking for 100% security, and it provides that."
"Overall, the intuitiveness of this product is pretty good."
"I would recommend to everybody that they use this solution; if they have a need that is similar to my need, then I would tell them, "Hey, this is the company to use, period.""
"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."
"We're very pleased with SpamTitan and the functionality that it has given us."
"SpamTitan is also easy to use; you just set it up and everything works the way it should."
"We haven't had any virus infections since implementing SpamTitan."
"When I started with my current company two years ago, it didn't have any type of spam filter, it was getting flooded and there were breached email accounts on a regular basis, but since I put in SpamTitan, I've had three breached accounts in Outlook over the past two years among our 160 employees and I've seen a drastic improvement in security."
 

Cons

"Our subscription plan for the solution has a limitation of bot signatures."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"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 response time for support must be reduced."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"For the topic of improvement, providing some training material is one of my suggestions."
"Operating and tuning the product is difficult."
"I was looking for some advanced features, like if I would receive an email that contains a legitimate file type, but the content is malicious, how I can protect against that?"
"The UI needs to be more user-friendly."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"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."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"The custom alerts have to improve a lot."
"There's room for improvement regarding the time frame for retrieving emails."
"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."
"The big issue that I've had is that the length of time that an email is kept in quarantine is only seven days and, in some cases, it is not even seven days... if I had a 20-day or 30-day repository, if someone came to me and said, "Hey, I can't get this back," I could end up getting it to them from the archive."
"We would like to improve the number of quarantine reports received per day. At the moment, only one is received within 24 hours."
"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."
"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."
"The admin user interface is very granular. It can be difficult, on a layer-by-layer basis, to wrap your head around it."
"The interface looks a little dated and could be modernized."
"The user interface of SpamTitan is fair, at best. The current one is a bit hard to navigate, and that was the biggest part of what made it a steep learning curve."
"They can increase some of the reporting around user logins. In order for us to make that determination, we have to pull down reports. They could make it a bit easier."
 

Pricing and Cost Advice

"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."
"The prices are slightly 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 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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution is not that expensive."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"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."
"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."
"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."
"The product is expensive."
"It's a user-base subscription."
"The pricing and licensing are acceptable. The licensing is somewhat different; TitanHQ gives us a peak cap of simultaneous users, which they calculate as the number of email addresses viewed through so many days or weeks. That's considered our number of users, but it isn't always a one-to-one relationship, making it harder to resell. We can't say precisely that the solution costs X per month per user, but that's how we present the price to potential customers, and we just ensure we receive more than we pay to TitanHQ. The licensing hasn't caused us any problems, but it would be better if the pricing were per-user. I know that's not easy to achieve on a technical level."
"The pricing was much more competitive than other solutions, so I was like, "Okay, let's give it a try.""
"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."
"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."
"Price-wise, this product is very compatible with our budget."
"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."
"But the most critical factor was cost-effectiveness. SpamTitan was much cheaper than Barracuda and offered the same value."
"They give you an update without charging you more for it, which is awesome. I like that a lot. It makes you feel appreciated as a customer."
