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.

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.

Quotes from Members

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

Pros

"I recommend it due to the experience of the people running it."

"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."

"Network traffic analysis is highly efficient."

"The most valuable features of this solution are the data correlation and vulnerability assessment."

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."

"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."

"The dashboard is the solution's most valuable aspect; it brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on," and the solution works well and allows me to have visibility into anomalous events."

"The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."

More AlienVault OSSIM pros

"I have seen a return on investment with Anomali, as it improves analyst investigation time, enhances threat visibility, and supports fast incident responses."

"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 positively impacts our organization, notably improving our vulnerability management program under reducing attack surface management."

"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."

"The most valuable aspect of Anomali is the threat modeling capability."

"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."

"Anomali is a very versatile platform, quite effective, and very fast when it comes to downloading and maintaining the information of the indicators of compromise."

More Anomali pros

Cons

"AlienVault OSSIM should improve the deployment and make it unified like the USM."

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."

"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."

"Sometimes it takes very long for your issue to get resolved."

"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."

"The price of this solution is very high and it could be cheaper."

"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."

"There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."

More AlienVault OSSIM cons

"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."

"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."

"One more improvement I would mention is regarding compromised credential monitoring. Anomali should increase their capability to fetch details from various dark web solutions where threat actors post compromised credentials."

"While reasonable, this is not the best available, and other products possibly have more AI maturity, such as Recorded Future and CrowdStrike Falcon."

"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."

"I believe Anomali could be improved by making the user interface more user-friendly."

"Pricing and licensing are good, but the costs for purchasing threat feeds are somewhat complicated and a bit on the higher side."

"I can mention one point regarding improvements for Anomali, which is more enhanced reporting flexibility."

Pricing and Cost Advice

"I used the paid version of the tool and found it to be expensive. It has been a while since I changed to Securonix. I will have to check whether AlienVault charges per device, user, or log."

"AlienVault OSSIM is free."

"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 solution is open source, so it's free to use."

"AlienVault OSSIM is an open-source solution."

"We are using a free version of the solution. If you purchase a license there are more features available but the price is a little high. The solution should be cheaper to allow more customers to be able to afford it."

"AlienVault OSSIM is expensive compared to its competitors."

"We are using the community version, which can be used for free."

More AlienVault OSSIM 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."
