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 Analyst at a computer software company with 51-200 employees

Has improved threat analysis by providing clear email correspondence history and reporting tools

The best features IRONSCALES offers are the investigation tabs, headers, and correspondence history, which stand out the most for me. The investigation tabs are valuable for my work because reporting goes a long way in terms of playbooks and having a full investigation. The investigation tab knows exactly how to put the information in a way that makes it very easy for reports to get done fast. Security awareness training is a big part of IRONSCALES. The platform offers a broad spectrum in terms of what campaigns can be run for security awareness for users as well as reporting back on how users interact with their mails and understanding where the vulnerabilities lie. IRONSCALES has positively impacted my organization by making email security simple in terms of controlling mails, understanding where the threats are, and protecting the organization itself.

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.

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 DDoS is better than its competitors for its security, deployment, and scalability."

"The solution has different options that can be used to differentiate DDoS attacks."

"Cloudflare Access is a stable solution."

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

"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."

"Cloudflare is simple to use."

More Cloudflare One pros

"We like IRONSCALES because it's easy to use and saves us some time."

"I would say the most valuable feature is what they call Themis. It's like a virtual analyst that uses the decisions that system admins make to generate a score for whether an email is legitimate, spam, or phishing. It gets better based on the decisions that we make over time. The automation piece is great as well. The integrated approach of email security combined with employee awareness training is excellent."

"The solution captures a bit more of the unknown, quantifies it, and applies intelligence to it to pick out and stop a lot of phishing emails that come through."

"The report function through Gmail is probably the most valuable feature. The next most valuable features are simulation and training."

"It is an important part of our security infrastructure and gives us confidence that we are protected from email threats."

"The best features of IRONSCALES are that most alerts are validated through AI, which reduces the fatigue of alerts that need to be worked on by the team handling the alerts investigation part."

"I couldn't believe that it could filter out 35% of the email."

"IRONSCALES has positively impacted my organization by making email security simple in terms of controlling mails, understanding where the threats are, and protecting the organization itself."

More IRONSCALES pros

"The most valuable features are the anti-phishing and anti-spam capabilities."

"The most valuable feature is the straightforward setup."

"The primary use case of this solution is to filter emails and only allow the legitimate ones through."

"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 of the solution stems from the fact that it is a highly reliable and dependable solution."

"The most valuable features are the anti-phishing and anti-spam capabilities."

Cons

"The onboarding process can be improved a little bit."

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

"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."

"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."

"Lacks a VPN feature to provide a secure connection to the data center."

"They don't have a person to provide support for customers using the solution under their free plan."

"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."

More Cloudflare One cons

"I would like it if IRONSCALES had some sort of reminder mechanism, meaning IRONSCALES knows if a user completed the training or not. As long as it hasn't been completed, it keeps reminding every so often, alerts the manager, etc. Right now, it is all in the hands of the employee, and not all of them continue the process, which is a shame."

"There's room for improvement in the campaign management. IRONSCALES has many built-in templates that I use, but you can also build templates from scratch. However, the interface for creating custom templates needs to be updated."

"The tool supports 15 to 16 languages, but the content it uses in the training in Spanish has certain limitations."

"The simulation and training piece could be improved by having more granularity in terms of scheduling how campaigns are run and allowing people to directly take the training rather than having to go through an official campaign."

"Even though they have been continuously improving it, it is not 100% there. We have had a few incidents where legitimate emails were getting blocked, and we had to manually remove those emails from quarantine. It is 90% effective or accurate because, on rare occasions, some emails from customers were not getting delivered. In one or two instances, their emails got blocked by IRONSCALES, and we had to manually remove the emails from quarantine. I would like them to improve their algorithm to avoid flagging genuine emails as malicious. I would also like to be able to whitelist certain email addresses. I'd love to be able to whitelist a particular customer."

"In addition to integrated training, they should also have personalized training that you don't have to do as part of a phishing campaign or a simulation."

"I would really prefer to drill down more on correspondence history. It provides detailed background information to actually understand what's going on."

"There's room for improvement in the campaign management."

More IRONSCALES cons

"The solution is not 100 percent stable and that can use improvement."

"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."

"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."

"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."

"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."

"I rated the overall solution a five out of ten. If a user is looking for a low-budget solution with mid-level security without AI features, Kaspersky Security for Mail Server is suitable."

Pricing and Cost Advice

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

"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."

"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 solution is not that expensive."

"The solution's pricing lacks transparency."

"Cloudflare Zero Trust Platform's pricing is good."

"The prices are slightly expensive."

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

"They are pretty much the same as all the other competitors in the market."

"I don't know about its pricing because I don't run the budget or pay the bills, but if it was extortionate, we probably would be looking to scrap it, and because we are not, I assume its price is okay."

"Considering the value it provides, it is definitely worth the cost. We don't have to do manual analysis and remediation of phishing emails, which saves us a lot of hours. Its licensing is based on the number of users being supported and the number of email addresses being protected. I'm not aware of any additional costs."

"The product is available as a middle-priced tool. I think it is not the cheapest solution."

"The tool is not very cheap, but it is affordable."

"As compared to everything else we looked at, it was good. It was the best value for the dollars."

"IRONSCALES is an expensive solution."

"There is an installation cost. Since we have this as a managed service, we pay for licensing and the managed service itself. Other than that, there are no additional costs."

More IRONSCALES pricing and cost advice

"My company makes annual payments towards the licensing costs solution."

"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."

"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."

"The solution is not expensive."
