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.

Improved email security has reduced spam, simplified encrypted mail, and strengthened user trust

The best features Barracuda Email Protection offers include good spam filtering and very good sandboxing of all links, as well as good encryption. It also has integrated logging for user management of their own spam. It has better filtering technology, so few are false positives as well, with excellent anti-spam engines and logging. It is extremely easy to install, configure, and set up, and there is excellent message tracking for folks that say they have not received an email they were expecting. Integrated logging and user management make my daily work easier because it is very easy to log in and to manage this tool, hence making it a very good tool for email protection. It also has excellent, easy-to-add designated users as site administrators, and it is competitively priced. It has a user-friendly portal, strong cloud-based features, and no additional maintenance cost, along with responsive support. Barracuda Email Protection has positively impacted my organization by handling encryption better than any other tool I have used before, which has increased our email protection significantly. Our security has also increased from forty percent to sixty-five percent, especially when dealing with all the threats that come through emails. It has been a great tool because we can handle email delays and delays on file scanning. When our partners are happy, we are very happy, and it has helped us have less time chasing bad emails. The fast implementation of encrypted mail keeps employees working with less interruption since they are happy, satisfied, and secure.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

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

"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 is a stable solution."

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

"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."

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

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

"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

"The main benefits Barracuda Email Protection provides for us are saving time and money because we don't run into any kind of attack or disruption in the mail service that we may face, including ransomware attacks."

More Barracuda Email Protection pros

"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."

"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."

"The DLP feature of Microsoft Defender for Office 365 is valuable, and we also use the DLP feature for email real-time detection."

"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."

"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."

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

"Defender helps us prioritize threats across our organization."

"Microsoft Defender for Office 365 is a cloud-based email filtering service that helps protect our organization against unknown malware and viruses by providing robust zero-day protection and includes features to safeguard our organization from harmful links in real-time."

Cons

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

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

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

"Our subscription plan for the solution has a limitation of bot signatures."

"The initial onboarding was causing us some confusion."

"Cloudflare DDoS has poor technical support."

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."

"The tool should provide on-premise versions. Currently, all versions are cloud-based."

More Cloudflare One cons

"Barracuda Email Protection needs better reporting and more robust integration with security awareness training platforms and third-party solutions."

"Barracuda Essentials can improve by continually adding more features."

"The platform's pricing needs improvement."

"The email encryption could be improved."

"Regarding the threat protection feature in Barracuda Email Protection, it does not help to manage threats or sophisticated threats."

"Considering it integrates with Azure, I would like to be able to effectively set up policies where people are by default included in certain settings."

"I would like to see some additional functionality in terms of employee monitoring, as part of a work-from-home security solution."

"The policies are set up in Barracuda by default; we don't have any control over them."

More Barracuda Email Protection cons

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

"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."

"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 wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."

"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."

"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."

"The cost of Security Copilot is up there right now, and I think it needs to come down for more people to adopt."

"The GUI is sometimes slow to fetch the device report and could be improved."
