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 is simple to use."

"Cloudflare Access is part of the Zero Trust philosophy."

"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 is a stable solution."

"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."

"Clover is the best product globally."

"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."

"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."

More Cloudflare One pros

"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."

"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."

"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."

"With Defender for Office 365, we have been able to increase the security posture across our organization."

"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."

"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."

"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."

"Microsoft so far has been good; we haven't faced any kind of disruption or anything else, it's a good product and good platform, I must say, and overall it's a good product and good service and we haven't dealt with bugs or glitches."

More Microsoft Defender for Office 365 pros

"When you say email security, it's about everything, incoming email, outgoing email, spam, phishing emails, unwanted marketing emails. You can set rules, but the main feature of Sophos Email is to make sure you don't get hacked. 95% of people who are hacked do not get hacked by typing the router password. They are hacked from the inside out, which means they send you a document that is a zero-day attack, you open it, nothing happens, but technically the attack is running in the background of your computer. This is how they gain access to your PC."

"The best thing about it is the logs."

"Sophos Email is a stable solution."

"The installation is straightforward."

"The feature of Sophos Email that we find most effective for detecting suspicious emails is primarily based on their signatures."

"I find the comprehensive features of Sophos Email most valuable."

"The filtering capabilities are precious and far superior to others I've used. It's intuitive in what it pushes to quarantine, and users can quickly review, free, or delete items without needing an administrator, making it ideal for a multi-user environment."

"The anti-spam functionality of Sophos Email is good."

More Sophos Email pros

Cons

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."

"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."

"The initial onboarding was causing us some confusion."

"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."

"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."

"Operating and tuning the product is difficult."

"The response time for support must be reduced."

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

More Cloudflare One cons

"Its price should be improved. Its cost is a major concern for us."

"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 visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."

"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."

"The pre-sales cost calculations could be more transparent."

"We still see many false positives from time to time with Microsoft Defender for Office 365, so it would be good if we can reduce those false positives and provide better workflows for our end users, as sometimes they may not know what to do when they encounter a false positive."

"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."

"I think Microsoft Defender for Office 365 can be improved by creating more educational pieces about not just looking for malware."

More Microsoft Defender for Office 365 cons

"Some existing functionality in the product needs better articulation in how data is displayed."

"It was sometimes hard to find the settings in the solution's interface."

"A lot of legit emails get quarantined."

"The solution has not found a way to block certain kinds of phishing emails."

"Servicing and support are areas with shortcomings where the solution needs to improve."

"Sophos Email does not work with split delivery. If I have a domain with 100 mailboxes and want to protect only 50, it is not recommended by Sophos or not possible to configure."

"The installation of Sophos Email could be easier. It's a bit difficult because setting up the email virtually requires some bit of technical knowledge."

"The solution should be able to support the cloud environment."

More Sophos Email cons

Pricing and Cost Advice

"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."

"Cloudflare Zero Trust Platform's pricing is good."

"The solution's pricing lacks transparency."

"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 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 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."

"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."

"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."

"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."

"The pricing has become expensive."

"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."

"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."

"We use exchange licenses, for which we get immediate support from Sophos."

"The solution is expensive."

"Sophos Email is neither cheap nor expensive."

"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."
