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.

Email security effectively detects a wide range of threats and improves productivity
Since we have been using Check Point Harmony Email & Collaboration for a year, we haven't encountered significant challenges. However, it would be beneficial if it could support other email security services beyond Microsoft and Google. Integration with other platforms would enhance its appeal since the features are commendable. While the analytics are commendable, they don't provide deep dive insights. They show the overall counts of malware, phishing, and business compromise emails, but there isn't a robust ability to dive deeper into those categories to see specifics. Analytics should allow us to explore which users received malware emails the most or trends among departments. Currently, we have to sift through manually, which is not ideal. A more profound analytical capability would elevate the tool to become the complete email security solution for any user.

Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

Quotes from Members

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

Pros

"Cloudflare is by far the most effective solution that I have come across."
"The solution has different options that can be used to differentiate DDoS attacks."
"This solution is easy to understand and easy to configure."
"Enables me to work from two locations."
"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."
"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."
"The most valuable features would be its ability to intercept phishing emails and emails laden with malware, viruses, false links, etc."
"I recommend Check Point Harmony Email and Collaboration to all types of companies, from small businesses to enterprises."
"It has just been phenomenal."
"Check Point Harmony gives us great visibility of the threats we are being exposed to, where they are coming from and what were they targeting, giving visibility of the weak gateways that could lead to an infection or a leakage."
"The product is reliable and sturdy."
"The anti-phishing feature is the solution's best feature."
"The solution has a very effective anti-phishing algorithm that detects a significantly higher number of phishing emails compared to the default Microsoft solution."
"In my opinion, it's one of the best products. It does protect other things like Slack and Salesforce, which are more about communication."
"If I had to mention one or two things that bring the biggest benefit, I would say the security of the emails and dealing with everything."
"Mimecast is pretty good, even if you're on Office 365."
"I have always found Mimecast to be very responsive; for example, if we see something come through, they address it and it helps to sort out the issues."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
"The solution is pretty straightforward to use and easy to set up."
"Mimecast certainly helped my customers reduce phishing emails."
"We used Mimecast Mailbox Continuity when we had a power issue, and it works, has been pretty reliable, and the support has been quite good."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
 

Cons

"They don't have a person to provide support for customers using the solution under their free plan."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Our customers no longer use Cloudflare because its service is subpar."
"Operating and tuning the product is difficult."
"The onboarding process can be improved a little bit."
"For the topic of improvement, providing some training material is one of my suggestions."
"Cloudflare DDoS has poor technical support."
"Lacks a VPN feature to provide a secure connection to the data center."
"At this time, the two-factor authentication does not work for Active Directory."
"The documentation is a little unintuitive, and I make an additional effort for the first deployment."
"The integration with Gsuite could be improved, especially when reporting the amount of emails it manages to filter."
"We understand that false positives are always there, but sometimes the notifications are more than expected."
"Improved support is needed as current support is slow."
"The NAVEX metrics that I have been using on the CloudGuard dashboard cannot be exported. If they were to add report exporting capabilities on each of metric objects on the dashboard, that would be awesome."
"There is a need for improvement in handling business email compromise."
"They could continue to offer more stringent security policy measures for threat point management."
"External security features need improvement."
"Certainly, the primary area needing improvement is Mimecast's customer support. Our experience as Mimecast customers has been less than satisfactory. Even when raising a priority ticket, the response time is unacceptably long, often taking around five to six hours. This level of service is disappointing. Additionally, there have been recurring service disruptions in the UK region, leading to extended email delays due to various service issues. This year alone, we've encountered such problems on approximately four occasions."
"The solution is very expensive."
"As a user, the user interface of the management console could be upgraded, for example."
"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."
"The installation is not so straightforward."
"The differentiation between bulk spam mail and campaign-related mail could be improved."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
 

Pricing and Cost Advice

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution's pricing lacks transparency."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution is not that 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 prices are slightly expensive."
"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 product is expensive compared to some competitors, especially for the SME segment."
"Do a full feature evaluation (interactive) with a support person. That is what I did."
"You can get CloudGuard as part of Infinity. When you do the solution through Infinity, it's a per user type of license cost."
"As we are a non-profit organization, we got the tool with a good offer. On a yearly basis, we pay 10,000 Euro for 500 users, which also includes the technical support part."
"Cost is the main concern that every customer takes into consideration, and Check Point always negotiates a price that is affordable."
"I rate the platform’s pricing a seven and a half."
"The product’s price is very high."
"The pricing is in the middle. Check Point's pricing is not the highest in the competitive market."
"The customers can select the license packages as per their requirements."
"The product has good pricing in terms of return on investment."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"The solution is expensive."
"For what it is, the product is overpriced."
"The licensing costs are per-user for the product that you get with them."
"It's an expensive solution."
"The product price is moderate. I rate the pricing a five out of ten."
