HarshBhardiya - PeerSpot reviewer
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.

Quotes from Members

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

Pros

"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."
"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."
"The solution is free to use."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"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."
"AlienVault OSSIM's GUI is very user-friendly."
"The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."
"Asset discovery is good."
More AlienVault OSSIM pros
"The playbooks feature in Siemplify is crucial for automation. We've utilized both standard and custom integrations with other security operation solutions, enhancing our flexibility. The user interface is generally straightforward, although recent changes may require some adjustment and Siemplify's integrations and capabilities offer potential support for various compliance requirements."
"Without hyperbole, I have never, in my entire career, encountered a vendor or a vendor community as awesome as Siemplify. Siemplify and the Siemplify Community quite literally made it possible for our SOC to increase almost five-fold in our number of clients and number of analysts and to go from a Monday to Friday 9-5 shop to a 24/7 shop all in the span of under a year and a half and all while continually adding capabilities and improving the services we offer to our clients."
"Overall, Google SecOps is a very useful service for security operations."
"Google SecOps is extremely useful for threat detection and hunting."
"The most valuable feature of Siemplify is the playbooks that can be created."
 

Cons

"The user interface could be improved."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"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."
"The solution needs more integration with cyber intelligence systems."
"The documentation could be improved."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"I don't like to work on OSSIM because it is unpredictable."
"We need more dashboards and we need more customization for dashboards."
More AlienVault OSSIM cons
"The main improvement could be in the accuracy and detail provided in threat descriptions."
"The main improvement could be in the accuracy and detail provided in threat descriptions."
"Building the playbooks could be easier and the integration could improve. It is a difficult process, such as what API connections need to be made."
"I'm inclined to say that I'd love to see some Machine Learning capabilities integrated into the platform, however, I just attended a demo this morning where Siemplify gave a sneak peek into some Machine Learning capabilities that they are currently developing and have roadmapped for release soon."
"We often encounter minor issues that could be improved, but we maintain communication with the developers and submit feature requests. Recently, I requested enhancements such as improved search functionality within playbooks and expanded options for exporting case data."
 

Pricing and Cost Advice

"AlienVault OSSIM is an open-source solution."
"AlienVault OSSIM is expensive compared to its competitors."
"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 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."
"We are using the community version, which can be used for 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 tool's licensing costs are yearly."
