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.

Providing comprehensive insight into alerts while working towards AI enhancement

I definitely recommend Rapid7 InsightIDR. It is becoming better, with improvements being continuously made to the product. Right now, I do not have any advice about Rapid7 for other users because every organization or user has different criteria or multiple use cases, so I refrain from commenting on that. I rate the overall solution seven out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The most valuable features of this solution are the data correlation and vulnerability assessment."

"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."

"Asset discovery is good."

"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."

"The paid version of the solution has reporting and better scalability options."

"I recommend it due to the experience of the people running it."

"With AlienVault you get everything in one box."

"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."

More AlienVault OSSIM pros

"The solution is very stable and works very well for what I need it to do."

"If you were on other solutions, you would notice that they use agents from third-party, from open-source, from a native OS, or from other tools. Here, however, it is an agent from Rapid7 itself. This adds to the solution's overall capabilities."

"The web interface is great — very useful and user-friendly."

"The solution is easy to use, and the interface is intuitive."

"Another very important part of insightIDR is the ability to collect data from endpoint devices via agent software. With a large remote workforce, this allows visibility into the endpoints that are connected to the internet, but not to the corporate network."

"The biggest reason why we chose Rapid7 was to gain value in a really quick time. Its deployment doesn't take months. It just takes a few days."

"InsightIDR helps us investigate an environment to discover information about incidents."

"The log aggregation and storage provided by InsightIDR has shown no issues with scalability; aggregating over one hundred millions events daily."

More Rapid7 InsightIDR pros

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."

"When comparing AlienVault OSSIM to other solutions it looks a bit outdated.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

"The correlation engine needs to be improved."

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

"Lacking in depth of reporting."

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

"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."

More AlienVault OSSIM cons

"Inability to get access to compliance reports within the solution."

"The integration capabilities of the solution have certain shortcomings where improvements are required."

"The interface for doing investigation needs to be enhanced with minor improvements that would make it more useful."

"Sometimes, it is hard to get the right queries to use. Currently, the tool lacks a pre-made set of queries."

"It takes time for the product's support team to resolve issues, making it an area of concern where improvements are required."

"The solution's XDR agents cannot compete with the XDR solutions out there yet."

"Rapid7 doesn't integrate well with all our security tools from various vendors, so we plan to switch. Many of our solutions work with Rapid7, but some do not. We are already searching for a replacement already."

"One thing that springs to mind is easier API integration with ITSMs. We are evaluating a new ITSM and I would like to have InsightIDR create a ticket when an attack is identified, and the ticket would be closed in InsightIDR when the ITSM resolution is completed. This would take out the "single point of failure" we currently have, if the email recipient is somehow absent, in recording the risk appetite for the incident and the actions taken to mitigate or not."

Pricing and Cost Advice

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

"AlienVault OSSIM is an open-source solution."

"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."

"AlienVault OSSIM is expensive compared to its competitors."

"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."

More AlienVault OSSIM pricing and cost advice

"Rapid7 InsightIDR is priced very well and is cost-effective."

"The pricing and licensing are competitive."

"Rapid7 InsightIDR charges us based on the endpoints we connect to."

"I rate Rapid7 InsightIDR's price a four on a scale of one to ten, where one is cheap, and ten is expensive."

"The solution has a mid-range price point in the market"

"Rapid7 InsightIDR is a cheaply priced product. On a scale of one to ten, where one is very expensive, and ten is very cheap, I rate the product's price at seven or eight."

"It is a reasonably priced solution."

"Licensing is straightforward. If, for some reason, you don’t meet the minimum licensing requirements, there is a third-party managed service that can help."

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

Parsing hundreds of trivial alerts. Managing a mountain of data. Manually forwarding info from your endpoints. Forget that. InsightIDR instantly arms you with the insight you need to make better decisions across the incident detection and response lifecycle, faster.
