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 has blocked sophisticated phishing and now protects inboxes with AI detection

The only challenge with Check Point Email Security (formerly Harmony Email & Collaboration) is that it is an API-based solution. In an API-based solution, the major challenge is that it can read email content and Google Drive content. This presents a data privacy challenge, and we had to mitigate it by signing a Data Processing Agreement and other agreements. Because it is not a traditional in-line solution, Check Point Email Security (formerly Harmony Email & Collaboration) connects with Google Workspace using API permission and can access email, attachments, sender, recipient information, links, and all metadata is with Check Point. Data storage and everything else is with Check Point, which is the challenge. This solution has a drawback because of API deployment, while other solutions are traditional secure email gateways that are in-line solutions. In those solutions, we need to change the MX record, but with this solution we do not need to change the MX record, which is a pro of API-based deployment. However, there is also a con in that with API solutions, the email is scanned but after delivery in the mailbox.

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.

Pros

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

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

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

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

More Cloudflare One pros

"The setup is very easy. I haven't faced any complexity with the setup of the solution."

"The ease of management and intuitive administration are excellent."

"The most valuable feature of the solution is the phishing protection it offers."

"As with most of the other Check Point products, the CloudGuard SaaS has the advanced visibility of the events and alerts."

"I like the fact that having granular information about the potential threats is received in email."

"The first most remarkable thing is the integration with the Office 365 solution, which is easy, fast, and totally transparent for the user."

"The solution helps to block spam emails."

More Check Point Email Security (formerly Harmony Email & Collaboration) pros

More Microsoft Defender for Office 365 pros

Cons

"Cloudflare DDoS has poor technical support."

"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."

"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."

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

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

"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."

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

"The initial onboarding was causing us some confusion."

More Cloudflare One cons

"The implementation could definitely be better. We had great support from Check Point, but there were some "got-you" moments where we got surprises as we were setting it up."

"The portal site is a bit slow at times. Plus, all new functions seem to be 'add-ons' instead of just being part of the platform."

"The worst thing that I have faced with Check Point has been their support."

"I would love it if they would do some work on the Postgres definition on the back-end."

"They must provide security to more email service providers."

"A phishing simulator would be helpful as a user training module."

"There is too much functionality, which makes it difficult to use. More guidance for users would be helpful."

"We are unable to export the reports from the dashboard, and if it is possible to do then it is not intuitive."

More Check Point Email Security (formerly Harmony Email & Collaboration) cons

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

"I was looking for some advanced features, like if I would receive an email that contains a legitimate file type, but the content is malicious, how I can protect against that?"

"The custom alerts have to improve a lot."

"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."

"Sometimes I have to recategorize things when it takes the wrong step and I do not want it to classify something as suspicious."

"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."

"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."

"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."

More Microsoft Defender for Office 365 cons

Pricing and Cost Advice

"The prices are slightly expensive."

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

"The solution's pricing lacks transparency."

"The solution is not that 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 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."

"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 is in the middle. Check Point's pricing is not the highest in the competitive market."

"I'm in this business as a system integrator, so I need to suggest Check Point to some customers who are comparing products. I sell Check Point, Fortinet, and Palo Alto solutions. In terms of licensing, this solution is quite competitive but very costly. For someone looking at security as a primary concern, they should only invest in Check Point. For a customer who is looking at security combined with pricing, Check Point might not be the core solution for them. In today's market, customers are looking for effective security with efficient pricing, and Check Point is not suitable for these types of customers."

"The product is expensive."

"Do a full feature evaluation (interactive) with a support person. That is what I did."

"The cost is similar to other competitors. It's not much higher."

"You can get CloudGuard as part of Infinity. When you do the solution through Infinity, it's a per user type of license cost."

"Having information stolen by a hacker would be more expensive than purchasing a license."

"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."

More Check Point Email Security (formerly Harmony Email & Collaboration) pricing and cost advice

"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."

"It's a user-base subscription."

"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."

"It is much more expensive than using another solution because we have had to include some options and upgrade our license."

"I know that the product is incredibly expensive."

"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."

"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."

"The license is expensive because the cost is based on the number of users."
