Independent Contractor at a comms service provider with 5,001-10,000 employees

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.

Chief Product Officer at ClusterPower

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

"The open vault component and the checking of vulnerabilities are the most valuable features. The page management helps with this. If you know how your device is vulnerable at least you can do something about it."

"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"

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

"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."

"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."

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

"The initial setup is straightforward."

More AlienVault OSSIM pros

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

"It's very stable and reliable."

"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."

"The intelligence of the system has been very impressive. It's not quite AI, but the technical bit where it correlates information, based on the seen attacks within an organization is good."

"It is scalable."

"I use the stack every morning to check the errors and it's just so clear. I don't see any disadvantage to using Logstash."

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

"The tool's functionality is good for overall security and incident response times."

More Elastic Security pros

Cons

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

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

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

"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."

"GUI could be improved."

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."

"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."

"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."

More AlienVault OSSIM cons

"This solution cannot do predictive maintenance, so we have to build our own modules for doing it."

"If you compare this with CrowdStrike or Carbon Black, they can improve."

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

"We had issues with scalability. Logstash was not scaling and aggregation was getting delayed. We moved to Fluentd making our stack from ELK to EFK."

"The initial configuration and setup are complicated and not straightforward."

"Elastic Security consumes a lot of resources, requiring a substantial deployment setup."

"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."

"I do not have any specific recommendations for improvements in Elastic Security, but I feel that the AI module should get more mature."

More Elastic Security cons

Pricing and Cost Advice

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

"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."

"AlienVault OSSIM is an open-source solution."

"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."

"OSSIM is free."

"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."

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

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

More AlienVault OSSIM pricing and cost advice

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

"Compared to other products such as Dynatrace, this is one of the cheaper options."

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

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

"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 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."

"The solution is not expensive and costs around ten dollars a month."
