An open-source solution that provide good detection and more visibility

The solution is not scalable. It impacts so hard. In the initial stages, AlienVault OSSIM can be suitable for small environments. There may be limitations if the customer expresses a desire to expand and add more devices. In such cases, we would need to either explore additional solutions or work within the constraints of the existing setup. We have set up alerts and configured everything in AlienVault OSSIM. It actively monitors for any security incidents. It provides us with regular updates and notifications about any ongoing activities. Only one person is using the solution. It is the perfect solution for small businesses. I rate the solution’s scalability a three out of ten.

Centralized monitoring improves security posture through rapid data processing

The processing part of Elastic Security is very interesting for us since we handle almost 7,000 to 8,000 alerts per minute. We require rapid processing speed for alerts and event data, and Elastic Security is very efficient at handling this level of data. Additionally, Elastic Security helps improve the security posture of Pakistan through centralized visibility and real-time processing.

Quotes from Members

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

Pros

"The initial setup is straightforward."

"The threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."

"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."

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

"The product is easy to use."

"The solution is free to use."

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

"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."

More AlienVault OSSIM pros

"It's a good platform and the very best in the current market. We looked at the Forester report from December 2022 where it was said to be a leader."

"It is the best open-source product for people working in SO, managing and analyzing logs."

"The most valuable feature is the machine learning capability."

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

"The most valuable feature is the search function, which allows me to go directly to the target to see the specific line a customer is searching for."

"The most valuable features of Elastic Security are it is open-source and provides a high level of security."

More Elastic Security pros

Cons

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."

"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 documentation could be improved."

"AlienVault OSSIM is costly."

"AlienVault OSSIM could improve by having better integration with some of the newer tools."

"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."

"GUI could be improved."

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."

"One thing they could add is a quick step to enable users who don't have a solid background to build a dashboard and quickly search, without difficulty."

"This type of monitoring is not very mature just yet. We need more real-time information in a way that's easier to manage."

"The Integration module could be improved. It is a pain to build integration with any product. We have to do parking and so on. It's not like other commercial solutions that use profile integration. I would also see more detection features on the SIEM side."

"We are paying dearly for the guy who is working on the ELK Stack. That knowledge is quite rare and hard to come by. For difficulty and availability of resources, I would rate it a five out of 10."

"The solution does not have a UI and this is one of the reasons we are looking for another solution."

"Upgrades currently released as stacks when it should be a plugin or an extension to save removal and reinstallation."

"An area for improvement in Elastic Security is the pricing. It could be better. Right now, when you increase the volume of logs to be collected, the price also increases a lot."

More Elastic Security cons

Pricing and Cost Advice

"The tool's licensing costs are yearly."

"AlienVault OSSIM is an open-source solution."

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

"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."

"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."

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.
