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.

We need to improve Trellix ESM by making sure that most of the logging devices available in the global market should be covered, and if there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that. We can add some new features regarding AI in the future for Trellix ESM, but the maturity will take a longer time. There are many false positives that happen in an environment during the first couple of months, or around six months, so the system analyst is not able to identify whether the event which has occurred is a true positive or a false positive.

Quotes from Members

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

Pros

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"The initial setup was straightforward. I didn't have any problems."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"The open vault component and the checking of vulnerabilities are the most valuable features, and the page management helps with this, because if you know how your device is vulnerable at least you can do something about it."
"You can customize the dashboards as well as the reporting."
"AlienVault OSSIM's GUI is very user-friendly."
"With AlienVault you get everything in one box."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"The support I have received from the vendor has been great."
"Trellix ESM utilizes fewer human resources and improves security and visibility."
"I would tell potential customers that ESM has a feature called all in one box."
"It is easy to use and deploy. It comes with user-friendly manuals."
"VirusScan Enterprise provides protection against real-time malware attacks."
"The most valuable feature is that if the scanning does find something, it quarantines it. Then you can decide what you are going to do with it."
"McAfee is the right choice for a low-budget solution."
"McAfee as a whole is a good solution."
 

Cons

"The correlation engine needs to be improved."
"Lacking in depth of reporting."
"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."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"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."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"We need more dashboards and we need more customization for dashboards."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"Just like any other software/hardware platform, once in awhile we have issues with software bugs, but McAfee's support is good in helping to fix these issues in a timely manner."
"The support from McAfee ESM could improve. They could improve the speed."
"It is not a very advanced solution, and it is for very generic use cases. It cannot cope with the advanced requirements that we're going to have. For example, for multiple authentication failures, it is still based on Windows events for detecting multiple login failures, whereas other companies are going beyond and working on implementing two-factor authentication. It is time to correlate the two-factor authentication results with authentification failures, which is not happening with McAfee ESM. The performance of the tool should be improved because it is very slow. The data display on the console is very slow in McAfee ESM. Its data storage is still old-fashioned, and it should be improved and upgraded to the latest versions. They have to come up with some new ideas to match what other leaders in the same domain are doing. For example, in Splunk, when you search for information for the last 60 days or five months, it quickly shows the information, but that is not the case with McAfee. The results should be quicker and faster on the console. They should integrate some additional features such as User Behavior Analytics (UBA) and automation. The threat intelligence part should also be improved on McAfee."
"Yes, sometimes it seems that versions with major upgrades come with some bugs and regressions that affected stability."
"We need to improve Trellix ESM by making sure that most of the logging devices available in the global market should be covered, and if there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that."
"Product currently requires Flash."
"There's no software support from McAfee."
"McAfee has many issues with integration. I am looking for an end-to-end integration such as EDR, and Next-Generation SOC 2.0."
 

Pricing and Cost Advice

"AlienVault OSSIM is 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."
"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."
"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."
"The solution is open source, so it's free to use."
"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."
"OSSIM is free."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"We pay for our licensing fees on a yearly basis, and there are no costs in addition to the standard licensing fees."
"The price of McAfee ESM is higher than some of the other solutions. There are additional features that can be added at an additional fee."
"We renew our license annually."
"Regarding pricing, Trellix ESM is not that expensive. It's less than half the cost of IBM QRadar."
"The product is slightly expensive."
"You should buy the distributed option instead of the all-in-one for environments with more than 1000 end points."
"McAfee is the right choice for a low-budget solution."
"It is an inexpensive product. We purchase its yearly license."
