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 product is easy to use."

"AlienVault OSSIM's GUI is very user-friendly."

"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 product is majorly used for threat detection of the agents on servers and endpoints."

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

"The initial setup is straightforward."

"The solution is very stable. Compared to Qradar and Splunk, it's very stable."

"With AlienVault you get everything in one box."

More AlienVault OSSIM pros

"We've found the initial setup to be quite straightforward."

"Its flexibility is most valuable. We can have a number of scenarios, and we can get logs from anything. If we know how to use Logstash, we can tweak it in many ways. This makes the logging search on Elastic very easy."

"The most valuable thing is that this solution is widely used for work management and research. It's easy to jump into the security use case with the same technology."

"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 solution has a good community surrounding it for lots of helpful documentation for troubleshooting purposes."

"We like Elastic Security because it's a REST API-based solution. That's the primary reason we use it."

"ELK documentation is very good, so never needed to contact technical support."

"One of the most valuable features of this solution is that it is more flexible than AlienVault."

More Elastic Security pros

Cons

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

"They can add more compliance templates."

"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."

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

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

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

"The user interface needs to be friendlier across the board."

"It's under heavy traffic. If you have heavy traffic, the system is slow."

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."

"The biggest challenge has been related to the implementation."

"I think because we are a cybersecurity company, the thing that can be improved is the prebuilt tools, especially quality. Compared to its competitor, they still have fewer prebuilt security rules. Elastic Security, in terms of generating alerts, cannot group the same products into one another. Even though the alerts are the same, they still generate them one by one. So, it is very noisy in our dashboard. I would like the Elastic Security admin to group all the same alarms into one alarm so that our dashboard is not noisy."

"Email notification should be done the same way as Logentries does it."

"It could use maybe a little more on the Linux side."

"Their visuals and graphs need to be better."

"We'd like to see some more artificial intelligence capabilities."

"In terms of what could be improved with Elastic, in some use cases, especially on the advanced level, they are not ready made, so you'll have to write some scripts."

More Elastic Security cons

Pricing and Cost Advice

"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."

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

"OSSIM is free."

"The tool's licensing costs are yearly."

"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 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."

More AlienVault OSSIM pricing and cost advice

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

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

"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."

"We are using the free, open-source version of this solution."

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

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

"It is easy to deploy, easy to use, and you get everything you need to become operational with it, and have nothing further to pay unless you want the OLED plugin."

"Elastic Security is free to use."

Overview

AlienVault OSSIM, Open Source Security Information and Event Management (SIEM), provides you with a feature-rich open source SIEM complete with event collection, normalization and correlation. 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.

AT&T
