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.

Comprehensive detection has protected email traffic and now simplifies endpoint security work
Sophos Email security is the primary product I use. It scans all your inbound and outbound email for malware. It also has a capability for looking for phishing and spear phishing content and blocking it. Email has an extended capability that includes what's called a secure web gateway. All user traffic gets managed through that, making it a combination product. The version of the product you run determines which features are available. Reporting is competent. There is scope for more improvements, which they will do as they do every year regularly. They keep updating the product. Reporting gives you the relevant details of what is happening, so it's mature on that front. The main benefit is security for your email. The beauty of the Sophos system is that the XDR functionality runs across the system. Sophos, Trend Micro, and Microsoft are the only three that have a very strong system with this concept. XDR stands for extended detection and response, and it's a technology where the system automatically exchanges security signals between the endpoint, the email, and other similar products of the same brand. If you have Sophos Endpoint and Sophos Email, you have very good connectivity from the endpoint to the cloud at the email level and to some extent onto the browsing traffic. You have a very rounded security aspect.

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."
"The blocking feature is very good."
"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."
"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."
"It will take the blow rather than our applications should an attack occur."
"Cloudflare DDoS mitigates DDoS attacks."
"Clover is the best product globally."
"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."
"The email protection is excellent, especially in terms of anti-phishing policies."
"Defender for Office 365 has helped eliminate having to look at multiple dashboards and that is the aspect I like most about it. It is simpler, effective, and convenient. The users like the process efficiency."
"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."
"The feature I like the most about Microsoft Defender for Office 365 is that it typically runs in the background—you do not know it is there until you need to access it."
"The most valuable feature is the integration; it's a single console, so we don't have to switch around between multiple products, and another valuable feature is the ease of operations and maintenance."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
"It is a stable solution...It is a scalable solution."
"There are quite a number of features in this solution, including VIP protection, time of click protection, the Sandstorm feature, and smart banners that help us know whether the email has malicious content."
"It has enhanced our approach to tackling malware and spam. It is a reliable product with a good user interface."
"Sophos Email is in the cloud and integrated with its firewall."
"The main benefit is security for your email, and the beauty of the Sophos system is that the XDR functionality runs across the system so you have very good connectivity from the endpoint to the cloud at the email level and to some extent onto the browsing traffic, giving you a very rounded security aspect."
"I have found Sophos Email to be scalable."
"I rate Sophos Email nine point five."
"I found the user interface friendly."
 

Cons

"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The onboarding process can be improved a little bit."
"Our subscription plan for the solution has a limitation of bot signatures."
"The initial onboarding was causing us some confusion."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"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 tool should provide on-premise versions. Currently, all versions are cloud-based."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"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?"
"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."
"We need to be able to whitelist data at the backend."
"The certification training for Defender for 365 needs to be deeper and incorporate Sentinel. I took all the security courses except one, and Sentinel isn't included."
"The UI needs to be more user-friendly."
"I'd like some additional features any product can give me to protect our environment in a better way."
"Configuration requires going to a lot of places rather than just accessing one tab."
"The solution's sandboxing and spam control features could be improved."
"I would like to see improvements in the initial setup process, ensuring better compatibility with diverse customer infrastructures."
"A lot of legit emails get quarantined."
"Enhancing rule creation and customization features would provide users with greater control over their email security settings."
"Sophos Email could improve DLP features."
"Sophos Email can improve security. We would like more security for our customers."
"Price is obviously a challenging part, and I think it is the biggest problem we have suffered from over the last two or three years due to a 7 to 8% hike per year, twice a year, which is why we have some renewals on Sophos Email, Sophos XDR, EDR, and the firewall, but due to price hike, they are unable to renew it."
"Sophos lacks real-time support, which would be a help to us."
 

Pricing and Cost Advice

"The prices are slightly expensive."
"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."
"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."
"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 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."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"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."
"It's a user-base subscription."
"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."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"The license is expensive because the cost is based on the number of users."
"I know that the product is incredibly expensive."
"There is an additional fee for their central managed console."
"The pricing could improve by having additional discounts. For example, when customers buy have more than 50 or more users, there should be additional discounts."
"I would rate the pricing of Sophos Email as a six. It is considered affordable as a standalone product, and there are no additional costs besides licensing. The pricing is fixed."
"It falls somewhere in the middle—it's not excessively expensive nor very cheap."
"I rate the price of Sophos Email a four out of five."
"The solution is expensive."
"Sophos Email is neither cheap nor expensive."
"The tool's price is reasonable. On a yearly basis, there is a 20 percent increase in prices, but it is not an issue."
