Setup Cost

Anomali pricing is medium to high, with reasonable costs; threat feeds complicate budgeting, typically involving senior staff management.
Microsoft Defender for Office 365 is cost-effective with E5, costly standalone, requiring careful planning for subscription-based licensing.
Pricing and licensing are good, but the costs for purchasing threat feeds are somewhat complicated and a bit on the higher side.
Associate Consultant at a tech vendor with 1,001-5,000 employees
My experience with pricing, setup cost, and licensing is that there are not many follow-ups, but once we interacted with the product team or the leadership of Anomali, they managed a lot with us, and it all paid off to reach a conclusion that we would continue with this product.

Lead Cyber Threat Intelligence Incident Response Engineer & Security Engineer at a retailer with 10,001+ employees
Correlating IOCs with the telemetry data we are ingesting from our data sources allows us to pull monthly reports identifying how many assets and users interacted with malicious content, giving insight into whether communications failed or users accessed restricted content, providing complete visibility of the IOCs traveling throughout our environment.

Global Leadership Council at a tech company with 10,001+ employees
Strategic threat intelligence has improved detection speed and consistently reduces analyst workload
Anomali can be improved in various aspects. Its AI-driven automation can further advance, and AI-powered investigation summaries can improve. User experience could be enhanced through simplification of workflows. Better board-level cyber risk dashboards could provide easier visualization. Additionally, Anomali could work on simplifying the pricing structure. Although it excels in threat intelligence aggregation and operationalization, stronger GenAI capability, improved executive reporting, and a more intuitive workflow for analysts would further increase SOC efficiency and add more business value. Regarding Anomali's AI capabilities, governance and security are quite good. Anomali has incorporated AI and machine learning primarily to improve correlation and prioritization. These capabilities are valuable but could be more mature. The platform could achieve better threat correlation, prioritization, more anomaly detection, and allow AI to accelerate intelligence analysis while further improving quality and relevance. The accuracy and reliability of Anomali's AI output are fairly reasonable and good. The AI engine works well, but this capability could be improved. Better threat correlation with threat actors, certain indicators of compromise, malware, and campaigns is possible. Threat prioritization could increase, and alert noise could be reduced through further de-duplication. While reasonable, this is not the best available, and other products possibly have more AI maturity, such as Recorded Future and CrowdStrike Falcon.

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.
