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

"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."
"Clover is the best product globally."
"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"Cloudflare Access is a stable solution."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"It will take the blow rather than our applications should an attack occur."
"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."
"The solution has different options that can be used to differentiate DDoS attacks."
"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."
"Scalability-wise, I do not think there are any issues so far."
"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have."
"The features I appreciate most about Microsoft Defender for Office 365 are admin notifications for potential threats along with protecting our Microsoft apps such as Outlook from potential phishing attacks."
"The initial setup was easy."
"Defender helps us prioritize threats across our organization."
"It has significantly decreased my time to detection and response."
"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."
"SpamTitan has improved our organization because it does a better job at filtering spam from getting in, along with the many phishing attempts."
"We're now using SpamTitan Plus. It has an extra feature so that if you receive an email with a link, it goes to the TitanHQ server and that link is also checked. That is probably the best feature."
"We get reports on blocked emails. I review them weekly to see who the heavy hitters are inside the office. We need our email addresses out there to do business, so we have sales and customer service email addresses that need to be out there. Those are the biggest targets for spam. SpamTitan cuts down the amount of spam that we receive, but it's about the same as Barracuda."
"If it blocks one piece of malware from getting into my system, it has probably paid for itself several times over."
"There was a noticeable improvement in spam in the first week."
"I've worked with different spam filters and I actually like SpamTitan the best."
"It filters some of the spam."
 

Cons

"For the topic of improvement, providing some training material is one of my suggestions."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The initial onboarding was causing us some confusion."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."
"Operating and tuning the product is difficult."
"Cloudflare DDoS has poor technical support."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"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."
"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 product must provide better malware detection."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"I think Microsoft Defender for Office 365 can be improved by creating more educational pieces about not just looking for malware."
"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."
"Configuration at the mid-level could be improved for the support team."
"The cost of Security Copilot is up there right now, and I think it needs to come down for more people to adopt."
"It should have reporting capability. It has logs, which are very extensive. It catches all the SMTP connections to the servers, but when you have hundreds of domains, you need to wait for about an hour for the logs to open, and there are millions of lines. If you want to find something specific, such as an email coming or an IP connection, and you want to troubleshoot that, it's very hard. So, I would recommend building a reporting system or log viewer with some filters. Currently, it is everything or nothing."
"The quarantine email message that users get on a scheduled basis is something users generally don't pay attention to, like every other communication they get from IT. The formatting of the quarantined email report that goes to the users on a regular basis is a little confusing for them. That could be improved."
"They need to keep up with the latest technology and add new features as they arise, e.g., artificial intelligence, new and improved updated lists, or new ways of tracking spam. They need to just keep up so the product is effective. Because, if all of a sudden viruses or spam starts getting through, then we might have to look at something else. However, so far, it has kept up and done a great job. So, we are happy."
"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."
"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."
"They could improve on the color of the interface."
"I believe the product is configured for the US or European market, not the Latin American market, and the scoring system is a little too strict for our market."
"Specifying your own filtering rules can be somewhat tricky. You can leave it alone or add your own filter rules using regular expressions. It would be nice to get a little more help configuring the regular expressions. That is quite complicated, and it's something I struggled with."
 

Pricing and Cost Advice

"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."
"Cloudflare Zero Trust Platform's pricing is good."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution's pricing lacks transparency."
"The prices are slightly expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven 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 pricing is normal. Considering its popularity, it's not overpriced."
"The license is expensive because the cost is based on the number of users."
"The product is very expensive."
"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."
"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 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."
"The product is expensive."
"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."
"The pricing for this solution is fair, and comparable with other products."
"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."
"I pay $650 per year for 50 licenses."
"The approximate cost is around $7000 USD."
"The price and the licensing are fair, allowing us to make a margin on the product. We paid a one-time fee for the sandboxing feature; apart from that, it's just the standard licensing."
"One user is the same price as 50 users and there isn't a discount until you get to about 500 users. 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."
