Tolu Omolaja - PeerSpot reviewer
Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

Provides comprehensive threat protection with suggestions for modernizing controls
I use the email gateway as the core of the email exchange between the Internet and our domain. The email gateway serves as the email exchanger The product offers protection, email security, anti-spam, and antivirus. It includes threat intelligence with advanced malware protection and many…

Saved us a big deal by catching malicious links and attachments sent directly to our staff and has also been helpful for educating our staff
It has helped immensely because it has gotten rid of malicious links and malicious attachments that have been targeted at our different staff members. It has definitely protected us on more than one occasion. Their integrated approach of combining email security and employee awareness training is excellent because the training is a reminder for staff to continually be on their feet and look out for the ever-changing landscape. It also lets us know who has been trained, who hasn't been trained, and what they're like. It integrates a risk ratio for all our employees. Its artificial intelligence and machine learning capabilities are very important because I don't want to have to manage 24/7. Having the AI to do a lot of the work for me is invaluable. Its automated detection and response capabilities are excellent. It does a wonderful job. They provide all the stats on what it has done. It gives you information about how much time is saved and all that kind of good information. Its automated detection and response capabilities have massively decreased the time we spend manually reviewing email events. Since May, it has taken care of 170 hours. So, it has saved 88 hours per analyst. It is very good in terms of the customization of the automated detection and response capabilities. It is granular, and you can adjust it however you want. If it is too high, you can turn it down. If it is too low, you can turn it up.

Quotes from Members

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

Pros

"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"One of the best features of the tool is its capability to aggregate insights from different workloads, basically from the Office 365 and endpoints part."
"The basic features are okay and I'm satisfied with the Defender."
"Defender helps us prioritize threats across our organization."
"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"The good part is that you don't have to configure it, which is very convenient."
"The solution is stable."
"The features and functionalities are much better than Microsoft's in-built Defender plan."
"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection. If there is any kind of challenge it will come across through email."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"Secure Email Threat Defense's scalability is good."
"The product offers protection, email security, anti-spam, and antivirus."
"The ability to see east-west traffic is its most valuable feature. Traditionally, email defense focuses on north-south, inbound-outbound, egress-ingress traffic. With Cisco Secure Email Cloud Mailbox, it's able to quickly identify, track, tag, and categorize emails that are internal. That can typically give us visibility into if there's an internal compromised account (for example). Someone can then use that internal compromised account to email additional accounts with either malicious software or links, but internal within that Office tenant. Effectively, that email message never leaves the tenant. Any of the mail gateways really do not have any method or way of seeing this traffic since it's not leaving the environment."
"On ease of use, it rates very high. It's something that I was able to get into without really looking at any documentation. I wanted to see what it felt like before I started looking at any documentation on how to use it, and it was very easy to use. It works very smoothly. The user experience is very intuitive. They did an amazing job on that."
"For what was being offered with IRONSCALES, I feel like we got an incredible deal."
"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."
"AI-driven phishing detection and incident remediation are valuable. It saves time from having to do manual analysis and investigation, and we also get alerts for phishing emails."
"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 biggest benefit is that we get fewer phishing and spam emails, so using IRONSCALES has made our environment much safer."
"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."
"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 stability is good."
 

Cons

"We need to be able to whitelist data at the backend."
"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"Configuration requires going to a lot of places rather than just accessing one tab."
"About eight months ago, we started to measure the quantity of phishing and spam that we have been receiving, and it has been increasing a lot. That means that protection for our email is not as good as we were expecting."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"There is room for improvement in terms of reporting."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"The pricing could always be better."
"The physical appliance has been discontinued, although the platform still exists."
"The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."
"We encounter issues while searching for missing emails."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"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."
"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."
"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."
"IRONSCALES should bundle more features together instead of separating them and charging additional licensing fees."
"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 only thing that I could say is that some of the reporting features could be better."
"The integration with Google Suite needs to be better. it's something they can work on."
"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."
 

Pricing and Cost Advice

"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"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 solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"It's a user-base subscription."
"The pricing has become expensive."
"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."
"The product is expensive."
"The solution’s pricing is manageable."
"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
"The feedback from vendors and customer is that it is expensive."
"It is expensive compared to other vendors."
"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."
"The tool is not very cheap, but it is affordable."
"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."
"They are pretty much the same as all the other competitors in the market."
"As compared to everything else we looked at, it was good. It was the best value for the dollars."
"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."
