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.

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

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"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."
"The dashboard is the solution's most valuable aspect; it brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on," and the solution works well and allows me to have visibility into anomalous events."
"You can customize the dashboards as well as the reporting."
"With AlienVault you get everything in one box."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"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."
"The solution is free to use."
"This solution helps us because we can find all of the logs in one place."
"What customers found most valuable in Elastic Security feature-wise is the search capability, in particular, the way of writing the search query and the speed of searching for results."
"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 helps improve the security posture of Pakistan through centralized visibility and real-time processing."
"Elastic SIEM is pretty stable."
"The best part about this solution is that it is open-source and free to use."
"Elastic has a lot of beats, such as Winlogbeat and Filebeat. Beats are the agents that have to be installed on the terminals to send the data. When we install beats or Elastic agents on every terminal, they don't overload the terminals. In other SIEM solutions such as Splunk or QRadar, when beats or agents are installed on endpoints, they are very heavy for the terminals. They consume a lot of power of the terminals, whereas Elastic agents hardly consume any power and don't overload the terminals."
"It's simple and easy to use."
 

Cons

"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."
"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."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"The biggest thing I always complain about is that the user intake is a very old version."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"I would advise others to not implement it for any enterprise-level organization."
"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."
"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."
"The solution needs to be more reactive to investigations. We need to be able to detect and prevent any attacks before it can damage our infrastructure. Currently, this solution doesn't offer that."
"If you compare this with CrowdStrike or Carbon Black, they can improve."
"The solution is stable if you don't touch it too much. Meaning, it's technically stable, but if there is a period of downtime, you will face quite a big hiccup in getting it running again and stabilized."
"Technical support could respond faster."
"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."
"With Elastic, you have to build the use cases for the specific requirement. Other products have a simple integration and more use cases to integrate out-of-the-box solutions for SIEM."
 

Pricing and Cost Advice

"OSSIM is free."
"The solution is open source, so it's free to use."
"AlienVault OSSIM is free."
"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."
"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."
"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."
"The licensing cost of Elastic Security is based on the daily ingestion rate. I can't recall the exact figure, but for 10GB of log action daily, it would cost around $20,000."
"Affordable but with additional costs"
"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."
"There is no charge for using the open-source version."
"Compared to other products such as Dynatrace, this is one of the cheaper options."
"We use the open-source version, so there is no charge for this solution."
"Elastic Stack is an open-source tool. You don't have to pay anything for the components."
"We are using the free, open-source version of this solution."
