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

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

"Asset discovery is good."

"The product is easy to use."

"The solution is free to use."

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

"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."

"The threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."

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

More AlienVault OSSIM pros

"ELK Logstash is easy and fast, at least for the initial setup with the out of box uses."

"ELK is open-source, and it will give you the framework you need to build everything from scratch."

"The solution is compatible with the cloud-native environment and they can adapt to it faster."

"The most valuable features are the speed, detail, and visualization. It has the latest standards."

"I can look at events from more than one source across multiple different locations and find patterns or anomalies. The machine learning capabilities are helpful, and I can create rules for notifications to be more proactive rather than responding after something has gone wrong."

"Elastic Security actually has a very good cost-benefit ratio compared to other vendors in the market."

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

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

More Elastic Security pros

Cons

"When comparing AlienVault OSSIM to other solutions it looks a bit outdated.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

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

"It's so hard to configure and explore something new on it."

"They can add more compliance templates."

"It takes some time. It does not give me a prompt response for any such [malicious] traffic. It takes time to get that alert from the AlienVault system."

"The user interface could be improved."

"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."

"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."

More AlienVault OSSIM cons

"We'd like better premium support."

"Authentication is not a default in Kibana. We need to have another tool to have authentication and authorization. These two should be part of Kibana."

"It's a little bit of a learning curve to understand the logic of searching for things and trying to find what you're looking for in Elastic Security."

"Better integration with third-party APMs would be really good."

"The solution could also use better dashboards. They need to be more graphical, more matrix-like."

"They don't provide user authentication and authorisation features (Shield) as a part of their open-source version."

"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."

"Elastic Security has a steep learning curve, so it takes some time to tune it and set it up for your environment. There are some costs associated with logging things that don't have value. So you need to be cautious to only log things that make sense and keep them around for as long as you need. You shouldn't hold onto things just because you think you might need them."

More Elastic Security cons

Pricing and Cost Advice

"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."

"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 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."

"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."

"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."

"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."

More AlienVault OSSIM pricing and cost advice

"There is no charge for using the open-source version."

"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."

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

"The tool's pricing is flexible and comes at unit cost. You don't have to pay for everything."

"Elastic Stack is an open-source tool. You don't have to pay anything for the components."

"The pricing is in the middle. I think it is not an expensive experience if we compare it with big names, for example, QRadar, and also Oxide. I think Elastic Security is quite cheap. I would rate the pricing of this solution a five out of ten."

"I can say that the product is cheaply priced."

"The solution is free."

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.
