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

"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 free to use."

"The most valuable feature is the logging capability."

"It has helped us remediate threats in the past by providing significant events that assisted in identifying suspicious activities, such as logins from multiple countries."

"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."

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

"Asset discovery is good."

More AlienVault OSSIM pros

"It improves because several sensors are deployed within the on-premise environment. It can be very efficient if the customer implements and operates it effectively."

"The solution's initial setup is easy."

"Features for user behavior analytics and the rules for attack review are good."

"The ability to ingest Office 365 log files, then process them into events and display them on a map."

"The platform offers unlimited storage and agent-based solutions."

"InsightIDR has allowed us to find potential security issues that we did not know existed, and get remediation quickly."

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

"Scalability-wise, I rate the solution a ten out of ten. As a cloud tool, the product is highly scalable."

More Rapid7 InsightIDR pros

Cons

"When comparing AlienVault OSSIM to other solutions it looks a bit outdated.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

"The documentation could be improved."

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

"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 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."

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

"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."

"AlienVault OSSIM is costly."

More AlienVault OSSIM cons

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

"I would like to see more development in InsightIDR towards building their SIEM solution and converting it to XDR."

"The APIs can be further improved in Rapid7."

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

"The ability to tune the collector for custom logs would greatly help."

"The searching feature in Rapid7 InsightIDR needs to evolve"

"I would like the ability to adjust the threshold of certain existing alerts. Currently the only option is to change the notifications or create my own alert."

"The solution needs improvement in threat intelligence. Increasing the depth of intelligence to help users understand more about threats is a possibility. My suggestion is to expand access to other websites or resources."

Pricing and Cost Advice

"AlienVault OSSIM is free."

"OSSIM is free."

"AlienVault OSSIM is an open-source solution."

"I used the paid version of the tool and found it to be expensive. It has been a while since I changed to Securonix. I will have to check whether AlienVault charges per device, user, or log."

"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."

"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."

"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."

More AlienVault OSSIM pricing and cost advice

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

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

"Licensing is by endpoint and amount of retention time (at least ours is). Default retention was one year, but we are able to push the retention further if needed. There's also a provide-your-own-S3 option for longer retention if you don't want to pay for the additional retention years in your Rapid7 agreement."

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

"I am sure that there are cheaper products out there, but none that meet so many of our needs whilst maintaining stability and usability."

"Rapid7 InsightIDR's pricing is reasonable."

"The pricing is good, and it is not very expensive."

"Rapid7 InsightIDR's pricing is reasonable but we have challenges with the Minimum Order Quantity. It is not reasonable for customers who have less than one hundred devices. If they can reduce Minimum Order Quantity, it is good. You have to pay around 5000-6000 dollars per year for the product. The pricing includes maintenance and support costs."

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.
