Cobe Van Coller

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.

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.

Emeka Ndulu

Cloud Solutions Architect at a tech services company with 201-500 employees

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 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 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."

"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."

"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 a perfect solution from my perspective; it's easy to understand and easy to configure."

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

More Cloudflare One pros

"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."

"By having an integrated approach of combining email security and employee awareness training, they've hit the nail on the head."

"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."

"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."

More IRONSCALES pros

"The technical support is good and quick to resolve issues."

"The product's scalability is good."

"The deployment capability is a great feature."

"Microsoft Defender for Office 365 is a stable solution."

"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."

More Microsoft Defender for Office 365 pros

Cons

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

"Operating and tuning the product is difficult."

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

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."

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

"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."

More Cloudflare One cons

"The user interface could be more attractive to users. The UI is not brightened or appealing."

"Its UI could be improved. My pet peeve with a lot of these cloud-based systems is that a lot of times, the interface for the management is a little clunky. If you live and breathe IRONSCALES all day long, you'll obviously know where everything is just from muscle memory, but the system is not designed for people to be in it all day long. You're only supposed to occasionally look at it. When things get moved around, it is not necessarily that intuitive. I'm an IT guy, and I can pretty much take the worst UI and figure it out, but the menus and the options in the interface could be a little cleaner graphically. If you have a quick problem that you want to resolve, it takes a little bit of digging in the admin console, whereas it should take a few clicks up front."

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

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

"I think the tool can continue to hone the product to ensure the detections are accurate."

"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 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. That's not available yet."

"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."

More IRONSCALES cons

"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."

"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."

"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."

"Configuration at the mid-level could be improved for the support team."

"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."

"The XDR dashboard has room for improvement."

"I'd like some additional features any product can give me to protect our environment in a better way."

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

Pricing and Cost Advice

"The solution's pricing lacks transparency."

"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."

"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 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."

"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."

"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."

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

"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."

"IRONSCALES is an expensive solution."

"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."

More IRONSCALES pricing and cost advice

"The product is very expensive."

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

"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."

"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."

"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."

"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."

"From the pricing point of view, like any other product in the market, there is scope for negotiation."

"I know that the product is incredibly expensive."
