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.

Provides robust email security features but requires improved modernization and complexity management

Modernization is an area that could be improved for Cisco Secure Email Threat Defense, as some features have lagged behind newer competitors, potentially offering more advanced analysis capabilities. The initial setup is not straightforward and requires expertise and time to master configurations such as spoofing and DLP. More control over backend functionalities and simplifying rule management could enhance user experience. The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration. Furthermore, the pricing might deter new users who could opt for alternative, more cost-effective solutions.

Quotes from Members

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

Pros

"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 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 DDoS mitigates DDoS attacks."

"Cloudflare, in my opinion, was easy to implement."

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

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

"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."

More Cloudflare One pros

"When we got the service, it included the email archiver with unlimited storage."

"At the moment, I am working with Sophos Cloud, Sophos Intercept X; when they introduced the XDR, we used it, and then when they introduced the Optix, we used it, and then we upgraded our subscription with them to MDR, so we are now utilizing Sophos Cloud Central MDR."

"The most valuable aspect includes attempts to spoof or compromise domains from external sources."

"The solution is straightforward to set up."

"Barracuda Email Protection has positively impacted my organization by increasing our email protection and security significantly, with our security increasing from forty percent to sixty-five percent, especially when dealing with all the threats that come through emails."

"We check the reports sometimes to see that frequent attacks and malicious emails are being blocked by the solution."

"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."

"The most valuable feature is the gateway."

More Barracuda Email Protection pros

"Cisco Cloud Mailbox is used for copying emails, anti-spamming, and securing the company's email, and we really enjoy the anti-spamming capabilities as well as the rejecting of bulk emails, which we can customize by adjusting the variables, and it is very user-friendly."

"Secure Email Threat Defense's scalability is good."

"This solution is easy to use."

"I highly recommend it as one of the best choices."

"Cisco Secure Email Threat Defense's best features include user management of graymail, enhancing security awareness by allowing users to manage cold calls, sales-based items, and ensuring email compliance."

"The features and functionalities are much better than Microsoft's in-built Defender plan, and this product has helped us to protect our organization from any malware attack in the past."

"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."

"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection. If there is any kind of challenge it will come across through email."

More Cisco Secure Email Threat Defense pros

Cons

"I would like them to include a VPN feature to provide a secure connection to the data center."

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

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

"Operating and tuning the product is difficult."

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

"The response time for support must be reduced."

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

More Cloudflare One cons

"I wish the interface of Barracuda Email Protection could have worked in a more responsive way, as sometimes I feel it is slow or laggy when I try to interact with it."

"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."

"Regarding the price, I find it pretty expensive. It is not even reasonable; it is pretty expensive because we are dealing with the South African market and our currency is not as powerful as the dollar."

"The platform's pricing needs improvement."

"The licensing and pricing need to be improved."

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

"The solution's graphical user interface (GUI) could be improved visually."

More Barracuda Email Protection cons

"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."

"The solution is a bit expensive. It could be cheaper."

"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."

"The search area has room for improvement."

"The search area has room for improvement. When you go to the next page, it remains at the bottom of the current page that you're on. Also, under the reports section, it allows you to see any "convictions," but if you want to search for those convictions you have to remember when they all came in and go back and edit the search accordingly. You cannot click on the list of convictions to actually see if you had a spike at a certain time."

"This solution could be improved by integration with Sandbox."

"The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration."

"The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned."

More Cisco Secure Email Threat Defense cons

Pricing and Cost Advice

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"The prices are slightly 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 solution's pricing lacks transparency."

"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 is not that expensive."

"The solution's pricing is moderate, where it is neither cheap nor expensive."

"We didn't have to pay a lot for the solution because we got it from a good vendor with a good user volume."

"The product is expensive."

"Despite a list price possibly around $40 per user, their market price allows customers to easily buy the solution."

"The price of Barracuda Essentials is better than some of the competing products."

"The price is similar to that of Microsoft 365."

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a seven out of ten."

"We pay annually. They never charged us for anything else. And they were quite a bit under that $20,000 mark. It was $19,074. And they've been pretty good about not skyrocketing the price or anything like that. It has gone up. It's gone up to $24,000 in 2020."

More Barracuda Email Protection pricing and cost advice

"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."

"It is expensive compared to other vendors."

"The feedback from vendors and customer is that it is expensive."

"The solution’s pricing is manageable."
