CV
Network Architect at IP Dimension
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.

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.

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 capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"The blocking feature 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 Access is a stable solution."
"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."
"Cloudflare is simple to use."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"We like IRONSCALES because it's easy to use and saves us some time."
"For me, the mobile app is most valuable. All other features are also very useful, but the mobile app makes it really easy for me to manage on the go. I don't have to be at my desk. I could be at the shops, or it could be in the evening when I am out, and I can get a notification on my phone that there is an incident that has been raised. I can sort it out very quickly without having to be at my work PC."
"It is just good to know that it is watching when we don't have to watch; I can go to sleep, and it is still working."
"For what was being offered with IRONSCALES, I feel like we got an incredible deal."
"The most valuable features of the solution are that it is easy to set it up, install, and manage the product."
"The biggest benefit is that we get fewer phishing and spam emails, so using IRONSCALES has made our environment much safer."
"IRONSCALES offers a sense of security and confidence from being well protected."
"The fact that it is set-and-forget is valuable. Once you turn it on, you very rarely have to micromanage it, whereas, with a lot of spam filters, you have to go in very often."
"The feature I like the most about Microsoft Defender for Office 365 is that it typically runs in the background—you do not know it is there until you need to access it."
"The benefit that stands out to me is the ability for multiple individuals to collaborate simultaneously within the same document. Additionally, there is the option to save the document directly in the integrated OneDrive or SharePoint."
"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."
"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."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"The product is not resource-intensive."
"The deployment capability is a great feature."
"The insights provided with Microsoft Defender for Office 365 are helpful because it comes with the E5 license, and by default, we can use a lot of capabilities."
 

Cons

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"For the topic of improvement, providing some training material is one of my suggestions."
"Our customers no longer use Cloudflare because its service is subpar."
"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."
"The initial onboarding was causing us some confusion."
"They don't have a person to provide support for customers using the solution under their free plan."
"Operating and tuning the product is difficult."
"Feedback could be enhanced."
"The integration with Google Suite needs to be better, it's something they can work on."
"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."
"As far as training awareness, I would give it 6.5 to 7 out of 10."
"There is a feature called Account Takeover, which isn't what I want it to be able to do. I know that they're working on that, but when they first started the Account Takeover feature in incident management, it didn't have much information. It didn't have any usability to it. I already had tools in place that were better."
"IRONSCALES should bundle more features together instead of separating them and charging additional licensing fees."
"There's room for improvement in the campaign management."
"I would love to see the indication of compromise and how the solution utilizes open source resources. It would be good to see that included in the paid versions."
"I would really prefer to drill down more on correspondence history. It provides detailed background information to actually understand what's going on."
"There is room for improvement in terms of reporting."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"We still see many false positives from time to time with Microsoft Defender for Office 365, so it would be good if we can reduce those false positives and provide better workflows for our end users, as sometimes they may not know what to do when they encounter a false positive."
"The GUI is sometimes slow to fetch the device report and could be improved."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"In one of the reports, I can get the exact place where a vulnerable file resides, but for that, I need to explicitly go into the device and check."
"The pre-sales cost calculations could be more transparent."
"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?"
 

Pricing and Cost Advice

"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 solution's pricing lacks transparency."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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."
"Cloudflare Zero Trust Platform's pricing is good."
"The prices are slightly expensive."
"The solution is not that expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The product is available as a middle-priced tool. I think it is not the cheapest solution."
"IRONSCALES is an expensive solution."
"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."
"As compared to everything else we looked at, it was good. It was the best value for the dollars."
"The tool is not very cheap, but it is affordable."
"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."
"We pay $3000 plus a little more a year for the number of employees we have, and we're not even that big. The solution is at the higher end in terms of cost. It's not the most expensive product, but I would say it's worth the price if you have a high volume of email traffic. In our case, the solution has inspected over 162,000 emails between three and four months. It saved us a lot of time and money. It's a worthwhile investment because a bad actor only has to succeed once; we must defend against everything in our business. IRONSCALES offers a sense of security and confidence from being well protected."
"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."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"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."
"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"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 pricing is normal. Considering its popularity, it's not overpriced."
"The pricing has become expensive."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
