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

"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 is by far the most effective solution that I have come across."

"I'm very satisfied with the environment and the dashboard."

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."

"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."

"Cloudflare is simple to use."

"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."

"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."

More Cloudflare One pros

"Since we have started using the solution, there have been fewer compromises."

"The ability to respond to threats if very important."

"We have seen a return on investment because if we would have received a phishing email, Microsoft Defender for Office 365 would help out to detect the threat instead of crashing down the whole company."

"Scalability-wise, I do not think there are any issues so far."

"The most valuable feature is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."

"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."

"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."

"Defender has reduced the time our security team spends on tasks by 10 to 15 percent, allowing us to focus on other areas."

More Microsoft Defender for Office 365 pros

"Endpoint and server protection are very effective."

"Our client recently received many emails, and their employees didn't realize these emails were phishing attempts. Consequently, they clicked on them and fell victim to the attack. Therefore, it is important to secure their system with Sophos Email Security."

"It filtered most of the spam and junk emails and quarantined them."

"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 tool's most valuable feature is the anti-spam detection filter. Its threat email intelligence features help to identify email data."

"The solution is very good at covering all of my organization's needs."

"It is really good for anti-spam, anti-malware, and especially for ransomware."

"Sophos Email provides both inbound and outbound filtering."

More Sophos Email pros

Cons

"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."

"For the topic of improvement, providing some training material is one of my suggestions."

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

"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."

"The initial onboarding was causing us some confusion."

"The onboarding process can be improved a little bit."

"They don't have a person to provide support for customers using the solution under their free plan."

"Feedback could be enhanced."

More Cloudflare One cons

"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."

"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."

"The XDR dashboard has room for improvement."

"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."

"Several simulation options are available within 365, and the phishing simulation could be better."

"The UI needs to be more user-friendly."

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

"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."

More Microsoft Defender for Office 365 cons

"The pricing could improve by having additional discounts."

"The tool's integration becomes an issue when the internet connection is weak."

"The product could include all the essential features and capabilities, similar to the on-premise, server-based version."

"Sophos Email could improve DLP features."

"A lot of legit emails get quarantined."

"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."

"Sophos Email can improve security. We would like more security for our customers."

"Sophos Email has few improvements to implement, including the handling of incoming emails in the systems. It needs to add additional feature that helps in enhancing the scanning processes of these emails. While adding these features, it should work towards improving the current features also."

More Sophos Email cons

Pricing and Cost Advice

"The solution is not that expensive."

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

"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 pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."

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

"The product is 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."

"The pricing has become expensive."

More Microsoft Defender for Office 365 pricing and cost advice

"The pricing is affordable, so I’d rate it around a four out of ten on the pricing scale. We pay about fifty pounds a month, including hardware so that costs may differ without it."

"Sophos Email is neither cheap nor expensive."

"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."
