Enables cost-effective security management for small businesses
Scaling for USM is always challenging for any product unless it is purpose-built or overbuilt at the front end. They will use Palo Alto and its competitors, and LevelBlue will manage that implementation. The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale. By pushing it to a cloud-based system, they've largely alleviated scale issues. It's native in Amazon but will also run in Azure. They have worked with cloud service providers to offer enough throughput at a cost reasonable for a corporation. Scaling was their biggest problem, and they've largely conquered those issues.

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.

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 feature is the logging capability."
"Asset discovery is good."
"This solution is very stable; it runs on a Linux box, you only interface with it through the GUI, it works behind the scenes, and it has never crashed in the time that I have used it."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"Network traffic analysis is highly efficient."
"The paid version of the solution has reporting and better scalability options."
"OSSIM is the only solution that includes the large number of modules that we need: a vulnerability scanner, a network IDS system, a host IDS system."
"AlienVault OSSIM's GUI is very user-friendly."
"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 think it's one of the awesome tools I've worked with to date."
"Anomali has positively impacted my organization because earlier we were not using any TIP format and were just dependent on open source, which gave us tons of irrelevant alerts, but with Anomali, we now get very specific and targeted alerts, allowing us to navigate through a handful of alerts that are applicable to us and saving a ton of working hours."
"Anomali positively impacts our organization, notably improving our vulnerability management program under reducing attack surface management."
"With Anomali, we benefit by obtaining threat information prior to incidents, making our threat hunts proactive and having incident response plans ready, which saves almost 40% of the time from the traditional model."
"Anomali has positively impacted my organization and my clients by helping them improve threat visibility, accelerate incident response, and make better use of their resources."
 

Cons

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"There needs to be more focus on the NOC and IIS in terms of developing applications for behavior detection."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"From a management console perspective and the maturity of the dashboards, I would probably put it slightly behind some of the other players that have been in the market for ages."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"I would like the solution to be able to integrate with my firewall, my IDS and my Honeypot solutions so that it can provide real-time reporting as things occur and then have alert sent to me on my phone when suspicious activity is happening."
"It's so hard to configure and explore something new on it. It is not easy to find the steps we need to follow in order to use the solution effectively."
"While reasonable, this is not the best available, and other products possibly have more AI maturity, such as Recorded Future and CrowdStrike Falcon."
"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."
"I can mention one point regarding improvements for Anomali, which is more enhanced reporting flexibility."
"Anomali can be improved by expanding its capability to capture a broader range of threats because it currently has limitations and may not catch everything occurring in the world, especially from the dark web."
"My experience with Anomali's customer support has not gone so well for us."
"I believe Anomali could be improved by making the user interface more user-friendly."
"Less code in integration would be nice when building blocks."
"Anomali Enterprise could improve by combining all the other tools' features into one solution."
 

Pricing and Cost Advice

"When comparing AlienVault OSSIM to Microsoft Sentinel, AlienVault OSSIM incurs additional costs due to its licensing price structure. If you are using AlienVault for security purposes at a certain level it can have a higher price point than the current pricing of Microsoft Sentinel."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"The price of AlienVault OSSIM is too high sometimes for us to present to our customers. The price should be lower. We are on a three-year license to use the solution. We had to pay extra for the support."
"AlienVault OSSIM is expensive compared to its competitors."
"We are using the community version, which can be used for free."
"OSSIM is open source, and USM is the paid license. So, if you want, you can switch to USM. There you will have to buy a license, and they have a support team that helps you out on issues you face."
"AlienVault OSSIM is an open-source solution."
"AlienVault pricing is the best. Whatever cost you are paying, you are getting a return on every penny... It's not like your IBM, your QRadar, or Splunk, where the cost is too high."
"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."
