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.
Emeka Ndulu - PeerSpot reviewer

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

"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."
"Cloudflare is simple to use."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Cloudflare Access is a stable solution."
"Enables me to work from two locations."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"It is a stable solution."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"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."
"IRONSCALES has enabled us to spend more time on other activities because it is just install and forget."
"The report function through Gmail is probably the most valuable feature. The next most valuable features are simulation and training."
"There is buzz around phishing awareness training. When I make a campaign, all of a sudden people in our organization are talking, thinking, and wondering about it. Therefore, it keeps people on their toes. That is perfect because it does exactly what we want it to do."
"Their anti-phishing platform is absolutely fantastic. The automated AI piece is amazing, and their technical support is fantastic."
"It is an important part of our security infrastructure and gives us confidence that we are protected from email threats."
"If a company is looking for something that is extremely robust, that has the ability to catch zero-day incidents, and they're not looking to spend an arm and a leg, there's no other choice."
"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"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."
"The deployment capability is a great feature."
"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."
"Technical support is very good. They are knowledgeable and respond quickly."
"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
"The coolest feature of Microsoft Defender for Office 365 is its ability to look for phishing emails."
"Scalability-wise, I do not think there are any issues so far."
 

Cons

"The response time for support must be reduced."
"They don't have a person to provide support for customers using the solution under their free plan."
"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."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Our subscription plan for the solution has a limitation of bot signatures."
"Our customers no longer use Cloudflare because its service is subpar."
"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 onboarding process can be improved a little bit."
"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."
"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."
"The integration with Google Suite needs to be better. it's something they can work on."
"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."
"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."
"The tool supports 15 to 16 languages, but the content it uses in the training in Spanish has certain limitations."
"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. It would be a small addition but add a lot of value for clients."
"The integration with Google Suite needs to be better, it's something they can work on."
"This is quite an expensive solution and understanding the pricing model and features is quite complicated and it can, in fact, be a nightmare when dealing with Microsoft."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"The UI needs to be more user-friendly."
"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."
"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."
"I think that Microsoft Defender for Office 365 could be improved if it could use VirusTotal to compare the programs or anything that I download."
"I think Microsoft Defender for Office 365 can be improved by creating more educational pieces about not just looking for malware."
"Several simulation options are available within 365, and the phishing simulation could be better."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"The solution's pricing lacks transparency."
"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."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution is not that expensive."
"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."
"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."
"They are pretty much the same as all the other competitors in the market."
"The product is available as a middle-priced tool. I think it is not the cheapest solution."
"IRONSCALES is an expensive solution."
"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."
"As compared to everything else we looked at, it was good. It was the best value for the dollars."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"It's a user-base subscription."
"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 has become expensive."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"The product is expensive."
