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."

"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."

"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."

"Cloudflare is simple to use."

"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."

"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 blocking feature is very good."

"Clover is the best product globally."

More Cloudflare One pros

"One of our clients didn't have the budget to invest in a SOC team, but we deployed the solution for them, and they now run a SOC with only one analyst."

"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."

"The coolest feature of Microsoft Defender for Office 365 is its ability to look for phishing emails."

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

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

"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."

"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."

"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."

More Microsoft Defender for Office 365 pros

"It is a stable solution...It is a scalable solution."

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

"I cannot guarantee any email by its name. It can be spam. Sophos Email helps to double-check whether an email is spam or not. It has a dashboard which gives an overview of the alerts."

"Endpoint and server protection are very effective."

"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."

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

"The speed and stability were fine."

"Sophos Email offers encryption and malware protection, provides visibility into emails, has 99% accuracy in catching spam, enhances organizational safety, integrates with various vendors like Microsoft, is deployable with any email service, prevents data loss, features authentication rules, synchronizes with Active Directory and Azure, and includes a self-service portal. The product is very flexible."

More Sophos Email pros

Cons

"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."

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

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

"Our customers no longer use Cloudflare because its service is subpar."

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

"Cloudflare DDoS has poor technical support."

"The initial onboarding was causing us some confusion."

"Feedback could be enhanced."

More Cloudflare One cons

"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."

"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."

"I assess the stability and reliability of the solution as seven out of ten."

"I'd like some additional features any product can give me to protect our environment in a better way."

"Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published."

"In one of the reports I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help."

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

"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."

More Microsoft Defender for Office 365 cons

"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's technical support is slow and unresponsive. You need to book time in order to get support."

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

"Sophos Email needs to increase the number of promos."

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

"The tool's pricing is expensive. In its future release, the tool should make reporting easier to view."

"A lot of legit emails get quarantined."

"Lacks visibility into spam emails."

More Sophos Email cons
