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
Helpdesk Internal Systems Manager at Active IT Systems
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 mitigates DDoS attacks."
"Enables me to work from two locations."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"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."
"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."
"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."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"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."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"The basic features are okay and I'm satisfied with the Defender."
"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."
"Scalability-wise, I do not think there are any issues so far."
"The product is not resource-intensive."
"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."
"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 email protection is excellent, especially in terms of anti-phishing policies."
"The overall system is straightforward to use, and the UI is excellent. It significantly streamlines the process of dealing with spam emails."
"The standout features include the anti-phishing feature, which is particularly advantageous as far as our clients are concerned; it was a very welcome addition for many of them."
"The product has a helpful interface."
"We have absolutely seen ROI. The regained productivity hours that we were able to claim since we automated the email protection have been really good. Our team of three people has seen an increase in our productivity, by around 30%, since implementing SpamTitan."
"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."
"The most valuable features of TitanHQ SpamTitan are how effective it is and how little maintenance it requires."
"One of the most valuable features is that it's very straightforward. It's a really simple interface. With our previous products, you could spend a week, if not more, training on those products just to figure out the interface. With SpamTitan it took an hour or two or three, tops."
"Another feature of SpamTitan that I like is the reporting. We are able to identify the users or accounts that have been attacked most. We can see information that shows us the sites that the user goes to, and that helps in launching an investigation of that user and how they use our resources."
 

Cons

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"They don't have a person to provide support for customers using the solution under their free plan."
"Cloudflare DDoS has poor technical support."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The response time for support must be reduced."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The initial onboarding was causing us some confusion."
"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."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"Microsoft Defender for Office 365 should be more proactive."
"The visibility for the weaknesses in the system and unauthorized access can be improved."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"The cost of Security Copilot is up there right now, and I think it needs to come down for more people to adopt."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"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."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"We have submitted requests for a feature which would be a total control panel… Our previous spam filter had that and it saved us from having to log in to the panel online, search for an email, pull it up, and figure out where it came from originally and why it got the spam score it did. That would be a huge improvement and time-saver because then we wouldn't have to be in the webpage for that."
"False positives may be an area for improvement. It's very rare that we see false negatives, but false positives might be an area where I, myself, could put some more effort into looking at the settings... Perhaps that's something in the user interface that isn't hugely clear."
"I'd like to see something like "My First SpamTitan," by which I mean, "Guide me through the things I need to set, and tell me about the things that you're setting already." That way I would get a good feeling for setting up the product, rather than having to figure it out by myself, which is what I did."
"The analysis of ransomware attachments could be improved. Other solutions seem to detect ransomware faster than SpamTitan does."
"It would be nice if the reporting feature could be updated. Also, the feel of the web interface is a little dated."
"The interface is a little outdated. The menus are simplistic and visually, it's pretty old."
"The product's GUI, dashboard, and speed could be better."
"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."
 

Pricing and Cost Advice

"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."
"Cloudflare Zero Trust Platform's pricing is good."
"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 prices are slightly expensive."
"The solution's pricing lacks transparency."
"The solution is not that expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"The product is very expensive."
"The product is expensive."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"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."
"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."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"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."
"SpamTitan has competitive pricing and flexible licensing. They allow up to 10% more that you use and then add it to the next tier of licenses."
"It's priced very reasonably. There are no additional licensing costs that affect me."
"We're satisfied with the pricing and licensing for SpamTitan."
"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."
"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."
"Partner profitability is good with Titan HQ's partner program. This means that I recommend it to clients who trust me. My time and effort to educate them is compensated by TitanHQ, who provides the solution to me at a lower price than what the public gets it at, then I can make some money."
"The price is quite advantageous; we were initially surprised at the pricing compared to other solutions, which made us doubt if this was the solution for us. Then, we discovered SpamTitan's features and how cost-effective it is. The sales team does an excellent job making our life easier in terms of pricing, which is another significant advantage of this product."
