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.

Helps to detect and generate reports on phishing emails and saves from email compromises
We use the solution for marketing and brand protection.  I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature.  The product's…

Email defenses have reduced phishing risk and support strong compliance and user awareness
The improvement needed is not necessarily in the product itself, but rather around how other organizations have evolved. The DLP discussion is no longer limited to email; it has gone to border level with companies like Zscaler, Netskope, and Palo Alto giving the complete full-stack SASE setup. When somebody has a SASE setup, then Mimecast Advanced Email Security DLP might not even be needed at a point in time. Mimecast Advanced Email Security needs to improve in this area because they are only focusing on a particular set of problems which is on email and human risk, whereas companies that need a slightly bigger picture will look elsewhere. The second thing is when you buy an XDR provider, they give you a complete holistic story around it, showing what has happened, which email somebody has clicked on, whether there have been any changes, and whether there is any network activity. You get a holistic picture. When pushing Mimecast Advanced Email Security to end customers, people are more often saying that they would rather buy XDR from another provider because the story when an analyst sees is complete in terms of what they see, whereas they only get an email story from Mimecast Advanced Email Security. Mimecast Advanced Email Security has to improve there. Companies like Abnormal AI cover more on UEBA and user behavior, and there are many things for Mimecast Advanced Email Security to improve in this area as well. It is less of a technology issue; they are doing very well on email. The conversation for them to have is on how to get into a broader level or how to get a tie-up to become a broader supplier. At least from a service provider landscape, I can say that.

Quotes from Members

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

Pros

"It is a stable solution."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Cloudflare, in my opinion, was easy to implement."
"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's a perfect solution from my perspective; it's easy to understand and easy to configure."
"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."
"Enables me to work from two locations."
"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"Agari gives us visibility of our domain security, helps us manage our SPF, DKIM and DMARC records, prevents spoofing of our domains for phishing and ensures that our marketing and other emails are received correctly and not rejected as spam."
"It comes with a lot of helpful tips for complicated areas."
"It is really important for large companies to have the brand protection that is provided by Agari."
"I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature."
"They are very flexible as far as feature requests go."
"Agari offers very good brand protection and they are the core founder of the DMARC standard."
"If spam or some kind of malicious email gets past Mimecast and gets into our email environment, we can go into Agari and we can search for it."
"The most valuable feature of Mimecast Mailbox Continuity is real-time alerts."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"The solution is stable and reliable. There are no bugs or glitches, and it doesn't crash or freeze."
"If you want the ease of use, then Mimecast, or at least a cloud solution, is the way to go."
"Mimecast Advanced Email Security is a good product and is very stable."
"I recommend Mimecast based on customer requirements and budget."
"Mimecast certainly helped my customers reduce phishing emails."
"The solution offers good technical support."
 

Cons

"I would like them to include a VPN feature to provide a secure connection to the data center."
"The response time for support must be reduced."
"Our subscription plan for the solution has a limitation of bot signatures."
"Feedback could be enhanced."
"The initial onboarding was causing us some confusion."
"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."
"Operating and tuning the product is difficult."
"They don't have a person to provide support for customers using the solution under their free plan."
"Some customers in the financial sector do not like the cloud solution because they don't want data to be transferred to a US-based cloud."
"The product's user interface is clunky. We have difficulty in finding what we need. I would also like to see automation in the onboarding processes."
"The protocol is quite complicated, which may not be something that could be improved, but it would be better if it was simplified."
"As a user, the user interface of the management console could be upgraded, for example."
"The feature that should be included is to remove the block on the encrypted files."
"Mimecast Advanced Email Security needs to improve in this area because they are only focusing on a particular set of problems which is on email and human risk, whereas companies that need a slightly bigger picture will look elsewhere."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"The lock in is very, very tight. It is impossible to move out of Mimecast to a different product, like Proofpoint or 365 ATP, and keep the chain of custody for every email that I've archived."
"The attachment scanning feature doesn't work properly."
"This solution can be frustrating. It blocks many things that should be going through."
"The product's interface could be improved to be more user-friendly."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution is not that expensive."
"The prices are slightly expensive."
"The solution's pricing lacks transparency."
"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 price of the licensing is based on the volume of email."
"The tool is not expensive and I would rate its pricing a four out of ten."
"The pricing depends on the number of users; per how many mailboxes you have, but they're pretty negotiable with that, too."
"It's an expensive solution."
"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."
"The product has good pricing in terms of return on investment."
"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."
"I'm always going to say the price needs to be lower, but it's reasonable."
"The price of Mimecast Mailbox Continuity is expensive."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
"The solution is expensive."
