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.

Provides reliable real-time email protection and offers competitive pricing features
Regarding Kaspersky Security for Mail Server, I have not compared with other solutions, but I will compare and provide feedback. It is a reliable and fast security solution, and I can say it blocks better than other competitor software. Kaspersky Security for Mail Server has support for Windows and Linux, but regarding improvement, I have to dig deep and will have to do research on that. I have not checked into much detail about what can be better in Kaspersky Security for Mail Server. I have checked in general. If given some time, I can check and compare with other solutions. Regarding Kaspersky Security for Mail Server, I have found this is quite a good solution. It has a good response and good detection capability. I have not checked other products, so I cannot give any detailed or specific feedback regarding that. From what I have checked from Kaspersky mail security, it is satisfactory.

Data governance has strengthened and automation now reduces risk and manual compliance work
Varonis Platform offers key features including data discovery, data classification, data analysis, governance, user and entity behavior analysis, also known as UEBA, which helps in ransomware detection, insider threat detection, and compliance reporting. It does a lot of automation from a remediation standpoint, as well as investigation and forensics. The number one feature that makes the biggest difference for my clients is visibility into unstructured data; that is the most difficult for organizations to achieve. They do not have a good understanding of where sensitive data resides, who has access to this data, whether this access is appropriate, and how data is being used. Varonis Platform provides visibility, governance, threat detection, and automated remediation around data. Varonis Platform is a great data discovery platform that provides visibility into sensitive data estimates and how it is being used. Clients have been able to reduce excessive permissions, strengthen their compliance posture, detect insider threats, and ransomware activity, which would otherwise be difficult and manual. Varonis Platform is deployed in my clients' organizations in a combination of all types. Many clients use Varonis Platform in a largely SaaS-based model since it is a data security platform consumed in this way, and many organizations still operate hybrid environments. As far as Varonis Platform is in a position to get the data source and identify systems, it can discover and classify more secure data. Deployment in most of our clients is cloud-based, connecting to Microsoft 365, AWS, or other SaaS applications such as Salesforce. In other environments, it is a hybrid deployment with SaaS and on-premises, including file servers, NAS devices, and AD servers.

Quotes from Members

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

Pros

"Cloudflare DDoS mitigates DDoS attacks."
"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."
"The solution has different options that can be used to differentiate DDoS attacks."
"Clover is the best product globally."
"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 Access is part of the Zero Trust philosophy."
"I'm very satisfied with the environment and the dashboard."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"With both of them working together, we have the perfect solution for mail."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"You can install the plugins on the same machine hosting your exchange solution. It's a good complement for Sophos security, which scans the traffic before it reaches your mail service. Kaspersky is on the mail server itself while Sophos handles the incoming traffic. With both of them working together, we have the perfect solution for mail."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"The most valuable feature is the straightforward setup."
"Varonis offers robust data access governance, allowing us to understand which sensitive data exists and who has access to it."
"The solution ensures that users have not accidentally shared sensitive information with the wrong people or too many people."
"Varonis Platform has positively impacted my organization by providing clarity regarding data and permissions, improving visibility, security, and compliance."
"There's also a 90-day policy where if a user is not using the warehouse, it will automatically delete that username."
"Overall, if you want to check your data from an initial point of view, Varonis Platform is the best use case you can consider."
"The analytics would have to be our most valuable feature."
"It can easily identify unusual behavior or access patterns that may pose a potential threat, while operating as a unified reporting system."
"Varonis Platform has definitely reduced the risk of data breaches at many client sites and has definitely lowered manual effort; manual effort has decreased by seventy percent due to automating data classification and permission reviews."
 

Cons

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The onboarding process can be improved a little bit."
"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."
"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."
"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."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"I have only made contact via email, and it is a little slow. I would give customer service a rating of six or seven. Improving Spanish support would greatly benefit users."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
"The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"The solution is not 100 percent stable and that can use improvement."
"For unstructured data monitoring, it's one of the top ones, if not the top one, due to its usability."
"It would be beneficial if the reporting in Varonis Platform could use PDFs instead of Excel for better graphs, as the dashboards are really good, and it would be nice to have simplified dashboards in PDF for business reporting purposes."
"There is one thing that if I add something manually, I get so many alerts. That's the biggest bad thing."
"For user-based reports, log on activity, and stuff like that, it doesn't seem to really be present like Log360."
"I would like it to have cloud integration."
"One area for improvement is the calculation engine. When applying rules in Varonis, especially for large datasets (terabytes of data), the calculations can be slow and require time to process. Speeding up this process would be beneficial."
"The potential areas of improvement I see for Varonis Platform are that it doesn't have a SIEM or SOAR console where you can see your incidents or a native style incident case management where you can see all your incidents and do the tracking of all those things."
"The licensing pricing model and module licensing can be complex for customers to understand."
 

Pricing and Cost Advice

"The solution is not that expensive."
"The solution's pricing lacks transparency."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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."
"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 prices are slightly expensive."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"The solution is not expensive."
"The solution offers one of the best prices possible to its users, making it even better than Barracuda. Kaspersky Security for Mail Server is ten times cheaper than Barracuda."
"My company makes annual payments towards the licensing costs solution."
"The pricing is good. It neither expensive nor cheap. It is average."
"Licensing is on an annual basis. Maintenance and renewal fees are separate. Varonis Datalert is quite expensive."
"The platform is expensive. I rate the pricing a nine out of ten."
"I would rate the pricing an eight out of ten, with ten being the most expensive."
"It's expensive, kind of, really expensive."
"You could do a subscription, where you pay yearly, or you could purchase it outright. The licensing cost is based on the number of users on the system that you are monitoring."
"Varonis Platform wasn't certainly the cheapest solution."
