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 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 will take the blow rather than our applications should an attack occur."
"Clover is the best product globally."
"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 solution has different options that can be used to differentiate DDoS attacks."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Cloudflare is simple to use."
"Cloudflare DDoS mitigates DDoS attacks."
"My experience deploying Microsoft Defender for Office 365 was seamless."
"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
"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."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"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."
"Microsoft Defender for Office 365 saves me time; it does save a lot of time, especially with the automation."
"The email protection is excellent, especially in terms of anti-phishing policies."
"Geo-blocking is a great feature."
"The user interface is great. Everything is in the browser; it is easy to set up and there are not a lot of tabs."
"Overall, SpamTitan has blocked spam by 99 percent, resulting in happy end-users whose clean inboxes make everybody more productive, saving time and money."
"It works as it should. It allows users to manage emails that they receive, meaning they can set up whitelists and blacklists."
"It provides security for the communication between the sender and receiver. It does the encryption perfectly. We ensure that emails are sent without any security breaches. The spam catch rate at the moment is almost 100%."
"So far, SpamTitan is the easiest and most efficient solution I've used."
"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.""
"I would highly recommend this solution to others."
 

Cons

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"They don't have a person to provide support for customers using the solution under their free plan."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Cloudflare DDoS has poor technical support."
"The initial onboarding was causing us some confusion."
"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 onboarding process can be improved a little bit."
"The pre-sales cost calculations could be more transparent."
"You should be able to deploy Defender for every subscription without the need to add servers."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"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."
"Microsoft Defender for Office 365 is not up to the mark in comparison with Wiz or Palo Alto."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"I would like to implement a secondary delivery pool for mass mailings, having an alternate pool for mass mailing lists since there is only a single mail queue with SpamTitan. For example, if 10,000 emails are being sent, then the queue will be large. Unfortunately, without a secondary delivery pool, legitimate emails will wait in the queue to be delivered to my email. Therefore, I would like to have two queues: one for everyday emails and another for mass mailings. Now, I have to decide whether to buy a second SpamTitan license just for this reason because I am very satisfied with the functionality of SpamTitan overall and don't want to use another sender's appliance for this."
"It could be improved a little bit on the speed side. When I am trying to troubleshoot a mail message that somebody is looking for in SpamTitan, sometimes setting up the filters for the quarantine is a little bit pokey."
"Sometimes, things can get caught back in spam that you had previously released."
"There needs to be improvement in response time due to the requirement of going through the ticketing system, which can cause delays."
"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."
"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."
"We're so used to SpamTitan now. If anything, there should be more ease of access for the users."
"When in the control panel, the context menu that appears when you right-click on an email should present options for adding the sender to the whitelist or blocking them."
 

Pricing and Cost Advice

"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 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."
"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 solution's pricing lacks transparency."
"The prices are slightly expensive."
"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."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"It's a user-base subscription."
"I know that the product is incredibly expensive."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"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."
"The license is expensive because the cost is based on the number of users."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"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."
"We're happy with their licensing model. It was a major factor in why we chose them."
"The price of this solution is low. When you do purchase everything is included in the licensing cost."
"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 pricing for this solution is fair, and comparable with other products."
"The price was great compared to other solutions that we looked at the time."
"Compared to all of the others, including the solution we used previously, SpamTitan is cheaper."
"For the service, the pricing is reasonable."
