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 feature I have found most valuable is credential monitoring. This feature is easy and quick."
"I have found Cyber threat intelligence (CTI) very useful and concise. The solution is easy to use."
"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."
"We now have a very robust collection of threat intelligence based on the capabilities that Anomali provides."
"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."
"Microsoft so far has been good; we haven't faced any kind of disruption or anything else, it's a good product and good platform, I must say, and overall it's a good product and good service and we haven't dealt with bugs or glitches."
"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 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."
"There are several features that I consider valuable."
"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 features are safe attachments and safe links."
"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

"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."
"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."
"Anomali Enterprise could improve by combining all the other tools' features into one solution."
"Less code in integration would be nice when building blocks."
"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."
"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"There is a different console for different things; I just want one consolidated console."
"There's room for improvement regarding the time frame for retrieving emails."
"If you look at other products, such as Wiz or Palo Alto's cloud, because they also have similar components in terms of how they protect cloud infrastructure or enable cloud security, Microsoft Defender for Office 365 is not up to that extent."
"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
"From a development point of view, if I wanted to do development on my actual machine where Defender is, the organization can set certain policies or Defender makes that prohibitive."
"We need to be able to whitelist data at the backend."
 

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."
"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."
"The product is very expensive."
"The pricing is normal. Considering its popularity, it's not overpriced."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"The product is expensive."
"The pricing has become expensive."
