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 protection has stopped phishing and secured cloud collaboration across all devices

Deployment is very easy since it is API based and does not require any harsh configuration. The DMARC management and DMARC forensic is the best feature. Their security engine provides everything such as DLP and encryption. Check Point Harmony Email & Collaboration provides almost 100% security for phishing emails. Their DMARC management is very standard compared with any other brand or any other email security provider. The best thing is that on a single tenant I can manage multiple services such as Harmony Endpoint, Check Point Harmony Email & Collaboration, Harmony Browser, mobile security, EDR, XDR, which is endpoint security, and SaaS. All of these services have a single dashboard. When giving security to email, in Check Point Harmony Email & Collaboration, I do not need to change any MX record or any DNS entry changes. I simply add one text record for DMARC and no changes are needed in the MX record of that particular domain. This is very easy because Check Point Harmony Email & Collaboration is in the tenant of Microsoft Office 365 and Google Workspace only. Check Point works on zero trust network technology. They are not only giving a feature of artificial intelligence but also machine learning summary. Machine learning summary is also given when they catch any kind of incidents such as phishing attacks, malware attacks, and ransomware attacks. They always provide real-time alerts for that. Real-time URL analysis is provided for phishing links and all these things. It gives 100% output for that and shows the source from where the malicious URL comes from. Additionally, they always provide threat emulation. This means the simulation of what danger happens when I click that particular URL is also provided in their report. It gives 100% protection to all BYOD devices. For example, one single Microsoft 365 account can be configured on different five devices. Many companies give email access to their employees on their mobile as well. In that case, if any malicious file is on the mobile and the employee would like to save it on OneDrive, due to this security, the user and administrator will get a real-time alert that this file is malicious and cannot be uploaded to OneDrive. This not only saves money but also saves time and prevents the organization from such cyber attacks.

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

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

"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."

"Cloudflare DDoS mitigates DDoS attacks."

"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."

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

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

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

"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."

More Cloudflare One pros

"One of the best features is the analysis and emulation carried out with each file attached to the emails, which makes each of the deliveries we make via email more secure."

"Data loss and data leakage prevention are well deployed which helps businesses to scale and expand effortlessly without any trouble."

"The main benefit is that hackers can't steal information."

"We are able to protect sensitive business data and maintain regulatory compliance with advanced data leak prevention (DLP)."

"The stuff that it's picking up and blocking and stopping from coming into our environment has been fantastic."

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

"The advanced phishing protection is proactive in catching threats before users even see them; it does not just block obvious spam, it can spot subtle impersonation attempts and suspicious links that appear legitimate at first glance."

"I recommend Check Point Harmony Email and Collaboration to all types of companies, from small businesses to enterprises."

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

"Overall, I would rate Microsoft Defender for Office 365 at a ten."

"The ability to respond to threats if very important."

"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."

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

"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."

"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."

"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."

"One of our clients didn't have the budget to invest in a SOC team, but we deployed the solution for them, and they now run a SOC with only one analyst."

More Microsoft Defender for Office 365 pros

Cons

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

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

"The initial onboarding was causing us some confusion."

"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 software has automated alerts, but the automated alerts are not available in the mobile app."

"For the topic of improvement, providing some training material is one of my suggestions."

"Operating and tuning the product is difficult."

"The initial onboarding was causing us some confusion."

More Cloudflare One cons

"The sanitization on the file needs improvement."

"Check Point Infinity Portal sometimes feels a bit slow, and there are performance issues that should be easy to fix."

"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."

"The integration with Gsuite could be improved, especially when reporting the amount of emails it manages to filter."

"At this time, the two-factor authentication does not work for Active Directory."

"They should consider a module that allows the customizing of reports so we can generate executive information for the client (to explain in simple language the general security situation in the SaaS environment)."

"if a phishing email were to get through and bypass the product — which very few do — it would be nice if, when a user clicked on that phishing email, they got a second-chance opportunity, a chance to double-check that they really wanted to proceed to that website."

"Its guides are not great."

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

"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."

"The changes to customer service, specifically the new model for support agreements, are not favorable."

"The certification training for Defender for 365 needs to be deeper and incorporate Sentinel. I took all the security courses except one, and Sentinel isn't included."

"The custom alerts have to improve a lot."

"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?"

"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."

"The visibility for the weaknesses in the system and unauthorized access can be improved."

More Microsoft Defender for Office 365 cons

Pricing and Cost Advice

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"The solution is not that expensive."

"Check Point is more expensive. That's the honest truth. So far, it's a good value for the money."

"Reasonable cost, quick and easy implementation, and transparent."

"The price is very good, based on what they deliver."

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

"This is a very good product if you are on the cloud, but the price is a little more expensive."

"Being able to keep the phishing campaigns out of my company has been ROI for me."

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

"The pricing is normal. Considering its popularity, it's not overpriced."
