Enables automated threat intelligence sorting and enhances proactive threat hunting capabilities
You have to have at least a threat intelligence background or a SOC analyst background to use it, as that's the information you'll dig around with in there. If you don't have that kind of knowledge, it probably can be a little hard to use, but they do provide training. They offer training not only for how to use the platform but also some basic threat intelligence training to explain what these things are and what these terms mean. My company is a customer of Anomali. I would recommend it to other people. I would advise making sure you don't pick it without testing other products and have your use cases well thought out and documented before testing, so you know it will solve the problems you're trying to address. Keep an open mind with it and realize that whatever you can dream of, you can probably do with the platform. Overall, I would rate Anomali an eight out of ten.

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 most valuable aspect of Anomali is the threat modeling capability."
"I have found Cyber threat intelligence (CTI) very useful and concise. The solution is easy to use."
"The feature I have found most valuable is credential monitoring. This feature is easy and quick."
"We now have a very robust collection of threat intelligence based on the capabilities that Anomali provides."
"I have found Cyber threat intelligence (CTI) very useful and concise. The solution is easy to use."
"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."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"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 DLP feature of Microsoft Defender for Office 365 is valuable, and we also use the DLP feature for email real-time detection."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"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 product's scalability is good."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
 

Cons

"A lot of tools can give you many features, such as CTI intelligence and a tax service reduction. However, many people are combining different tools together to have more capabilities. It is up to the consumer whether they want to have multiple tools or have one tool that serves the purpose. Anomali Enterprise could improve by combining all the other tools' features into one solution."
"An area for improvement is the intelligence sharing within the Anomali community. The tagging system can be inconsistent, as any company can use any tags for their reporting."
"Support in the past has been top-notch, but recent trends indicate that it has taken a back seat, as we often don't get answers for days."
"Less code in integration would be nice when building blocks."
"Anomali Enterprise could improve by combining all the other tools' features into one solution."
"I assess the stability and reliability of the solution as seven out of ten."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"The visibility for the weaknesses in the system and unauthorized access can be improved."
"We need a separate license and we don't know how to get the license that is required."
"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."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
 

Pricing and Cost Advice

"When comparing the price of Anomali Enterprise to other solutions it is in the medium to high range. However, I am satisfied with the price."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"The product is very expensive."
"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."
"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."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"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."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"I was working in the government and it was too expensive for us to use our Microsoft products."
