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.

Chief Product Officer at ClusterPower

Has improved threat detection with deep log analysis and streamlined investigation workflows

The most useful features I find in Elastic Security are the forensic ones that allow us to carry deeper analysis into the logs for in-depth investigations, and the dashboards, with the reporting dashboard being quite user-friendly. Elastic Security is quite good at identifying threats, as it is part of the deep investigation tool that I mentioned before. Unless we need to look further into a certain log, we can carry out a deeper analysis and forensics on those particular logs. I can assess the impact of Elastic Security's real-time data analysis on our threat response efficiency as working pretty good. We are looking for real-time analysis because we have a continuous inflow of logs from different sources: from our cloud, from Active Directory, from our network. So it works pretty well.

Quotes from Members

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

Pros

"Its user-friendliness is the most valuable. It is very easy to use and explore. The dashboard is very well packaged and integrated. You don't have to spend a lot of time in configuring it and checking out the RPM etc. It is also free and very powerful."

"Better than other SIEM solutions because almost everything can be integrated."

"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."

"The open vault component and the checking of vulnerabilities are the most valuable features. The page management helps with this. If you know how your device is vulnerable at least you can do something about it."

"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."

"Asset discovery is good."

"The initial setup is straightforward."

"The product is easy to use."

More AlienVault OSSIM pros

"The scalability is good. It can be scaled easily in the production environment."

"Elastic Security is cost-effective compared to Defender and CrowdStrike."

"Elastic Security is very easy to adapt."

"The most valuable feature is the ability to collect authentication information from service providers."

"It can handle millions of loads at a time, and you can always use the filters to find exactly what you are looking for and detect errors in every log message you are searching for, basically."

"Elastic Security helps improve the security posture of Pakistan through centralized visibility and real-time processing."

"The solution is quite stable. The performance has been good."

"I like the indexing of the logs."

More Elastic Security pros

Cons

"AlienVault OSSIM is costly."

"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 user interface could be improved."

"We need more dashboards and we need more customization for dashboards."

"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."

"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."

"Sometimes technical issues take very long to get resolved."

"I don't like to work on OSSIM because it is unpredictable."

More AlienVault OSSIM cons

"The price of this product could be improved, especially the additional costs. I would also like to see better-quality graphics."

"Installation is a little bit overwhelming, so improvements on the installation site could make it easier."

"Sometimes, the solution isn't the easiest to use."

"Anything that supports high availability or ease of deployment in a highly available environment would help to improve this solution."

"The problem with ELK is it's difficult to administer. When you have a problem, it can be very, very difficult to rebuild indexes."

"Elastic has one problem. In the past, Elastic Security was free. Now, they currently only offer the basic license or a certain period of time."

"Elastic Security's maintenance is hard and its scalability is a challenge. There are complications in scaling and upgrading. The solution needs to also provide periodic upgrade checks."

"It would be better if Elastic Security had less storage for data. My customers do not like this. Other vendors have local support in different countries, but Elastic Security doesn't. I would like to have Operational Technology (OT) security in the next release."

More Elastic Security cons

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."

"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."

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

"The tool's licensing costs are yearly."

"AlienVault OSSIM is an open-source solution."

"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."

"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."

More AlienVault OSSIM pricing and cost advice

"The base product is open-source but if you need advanced security features then you need to pay for the subscription. Elastic Security's price is reasonable in some cases and in other cases it's not."

"The solution is free."

"This is an open-source product, so there are no costs."

"It's a monthly cost with Elastic SIEM, but I am not sure of the exact cost."

"Compared to other products such as Dynatrace, this is one of the cheaper options."

"Compared to other tools, Elastic Security is a cheaper solution."

"Elastic Security is free to use."

"Its price is fine. Its licensing works on a yearly basis. We have to renew the license every year. I also have a good experience with Darktrace. When we buy Darktrace, we get training free of cost, which is not there in Elastic. We have to pay extra for training. There is certainly room for improvement."

Launched by security engineers because of the lack of available open source products, AlienVault OSSIM was created specifically to address the reality many security professionals face: A SIEM, whether it is open source or commercial, is virtually useless without the basic security controls necessary for security visibility.
