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.

SohailHyder

Head of Cyber Security at Super Secure

Has supported compliance needs for mid-sized organizations but lacks customization and advanced integration

If we pitch Rapid7 InsightIDR against solutions such as SIEMs from Splunk or LogRhythm, it is not as customizable as a SIEM solution is. This is where it can improve if we keep in front the feature sets of a complete SIEM solution. Most common in the market is QRadar, but it is depleting now. It has been taken over by some other products such as Splunk and LogRhythm. If we compare these things with Rapid7 InsightIDR, then there are definitely some gaps that need to be filled. Data retention is also one concern because Rapid7 InsightIDR is cloud-based and operates on a subscription model. Whatever data you want to retain, it has to be paid for separately or it has a cost. Other solutions that are on-premises can have their own infrastructure or they provide some data retention for a month or in some capacity-wise, they provide that solution to them which makes them more attractive.

Quotes from Members

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

Pros

"With AlienVault you get everything in one box."

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

"AlienVault OSSIM's GUI is very user-friendly."

"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 threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."

"The most valuable feature is the logging capability."

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

"Network traffic analysis is highly efficient."

More AlienVault OSSIM pros

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

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

"We were able to identify criminals attempting to login from China and put a stop on their IP locations."

"Dashboards, including the main screen, provide much-needed information at a glance, without hours of coding and sifting through logs to find it. In case of an actual security incident, I have faith that insightIDR has retained all logs in a secure manner that prevents log tampering as well."

"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."

"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."

More Rapid7 InsightIDR pros

Cons

"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."

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

"The correlation engine needs to be improved."

"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."

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."

"AlienVault OSSIM’s configuration and integration could be a little easier."

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

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

More AlienVault OSSIM cons

"The searching feature in Rapid7 InsightIDR needs to evolve"

"The product allows us to make only 30 custom rules."

"InsightIDR's integration with other solutions could be improved. Also, I'd like more control from the portal over what's happening on the endpoint side. For example, when I see an attack on an endpoint, I want to be able to stop it from the portal."

"The APIs can be further improved in Rapid7."

"There is a future in AI with Rapid7, however, it is not fully operated. There are certain limitations with Rapid7 that I am working on."

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

"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."

"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."

More Rapid7 InsightIDR cons

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."

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

"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."

"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."

"AlienVault 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."

"AlienVault OSSIM is an open-source solution."

"OSSIM is free."

More AlienVault OSSIM pricing and cost advice

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

"It is more reasonably priced than other vendors."

"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."

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

"The team is very willing to work with companies. My suggestion is to call the Rapid7 sales department and see how they can help."

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

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.
