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

"What I like about this product, is that it is a fully-fledged solution."
"Better than other SIEM solutions because almost everything can be integrated."
"The threat policies of the solution are always very advanced and the best in the market, and they are very persistent in terms of keeping up with security protocols."
"OSSIM is the only solution that includes the large number of modules that we need: a vulnerability scanner, a network IDS system, a host IDS system."
"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"Network traffic analysis is highly efficient."
"The initial setup is straightforward."
"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."
"Elastic Security makes data communication easier."
"The intelligence of the system has been very impressive; it's pretty accurate and gives you good details to create an intelligence report and present that to your C-level management."
"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."
"It's quite stable; we have not seen it going down at all for the last three years and it's working well consistently."
"The most valuable features are the speed, detail, and visualization. It has the latest standards."
"This solution enables us to monitor application performance from Elasticsearch and we can predict some behaviors for applications using ELK."
 

Cons

"The user interface could be improved."
"The user interface needs to be friendlier across the board."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"The incidence reporting could be better."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"GUI could be improved."
"The solution is not scalable."
"The process of designing dashboards is a little cumbersome in Kibana. Unless you are an expert, you will not be able to use it. The process should be pretty straightforward. The authentication feature is what we are looking for. We would love to have a central authentication system in the open-source edition without the need for a license or an enterprise license. If they can give at least a simple authentication system within a company. In a large organization, authentication is very essential for security because logs can contain a lot of confidential data. Therefore, an authentication feature for who accesses it should be there."
"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 tool should improve its scalability."
"Technical support could respond faster."
"Elastic Security consumes a lot of resources, requiring a substantial deployment setup."
"The Integration module could be improved. It is a pain to build integration with any product."
"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."
"We'd like to see some more artificial intelligence capabilities."
 

Pricing and Cost Advice

"AlienVault OSSIM is an open-source solution."
"We are using the community version, which can be used for free."
"The solution is open source, so it's free to use."
"The tool's licensing costs are yearly."
"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."
"OSSIM is free."
"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."
"The price is reasonable. It probably costs the same as ArcSight and LogRhythm SIEM. FortiSIEM might cost less than Elastic Security. There are no hidden or additional costs."
"I can say that the product is cheaply priced."
"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 not expensive and costs around ten dollars a month."
"When compared to other products, the price is average or on the low side."
"I find it better than Splunk in terms of cost-effectiveness. For cost-effectiveness, I would rate it a nine out of 10."
"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."
"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."
