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.

Gives us one place to investigate and respond to threats, and automation eliminates manual work
They can work on the EDR side of things. It is already really superb, because of the kinds of features we get with the EDR solution. It's not a standard EDR and they have recently enhanced things. But the problem is with onboarding devices. I have different OS flavors, including a large number of Linux, Windows, macOS, and some on-prem machines as well. Every time we need to onboard these kinds of machines into the EDR, we need to do it with the help of Intune, to sync up the devices, and do the configuration. I'm looking for something on the EDR side that will reduce this kind of work. They can eliminate having to do manual configuration for the machines, and check the different types of configurations for each OS. In some cases, it does not support some OSs. If they could reduce this type of work, that would be really amazing.

Quotes from Members

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

Pros

"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 initial setup is straightforward."
"Network traffic analysis is highly efficient."
"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 this solution are the data correlation and vulnerability assessment."
"The initial setup was straightforward. I didn't have any problems."
"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."
"The solution is very stable. Compared to Qradar and Splunk, it's very stable."
"The initial setup is very simple and straightforward."
"Log aggregation and data connectors are the most valuable features."
"We can use Sentinel's playbook to block threats. It covers all of the environment, giving us great visibility."
"The connectivity and analytics are great."
"Microsoft Sentinel stands out among SIEM tools for its user-friendliness and powerful built-in query language."
"It is always correlating to IOCs for normal attacks, using Azure-related resources. For example, if any illegitimate IP starts unusual activity on our Azure firewall, then it automatically generates an alarm for us."
"The pricing of the product is excellent."
"It is able to connect to an ever-growing number of platforms and systems within the Microsoft ecosystem, such as Azure Active Directory and Microsoft 365 or Office 365, as well as to external services and systems that can be brought in and managed. We can manage on-premises infrastructure. We can manage not just the things that are running in Azure in the public cloud, but through Azure Arc and the hybrid capabilities, we can monitor on-premises servers and endpoints. We can monitor VMware infrastructure, for instance, running as part of a hybrid environment."
 

Cons

"AlienVault OSSIM is costly."
"The user interface needs to be friendlier across the board."
"The incidence reporting could be better."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"The correlation engine needs to be improved."
"It's so hard to configure and explore something new on it."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"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."
"Sentinel still has some anomalies. For example, sometimes when we write a query for log analysis with KQL, it doesn't give us the data in a proper way... Also, the fields or columns could be improved. Sometimes, it is not giving the desired results and there is a blank field."
"Microsoft Sentinel's search efficiency can be improved, especially for queries spanning large datasets or long timeframes like 90 days compared to competitors like Splunk."
"The on-prem log sources still require a lot of development."
"It has been a challenge with Azure Sentinel to onboard the Syslog server from FortiGate. Azure Sentinel can work better on that shift between the Syslog server and a firewall."
"There is room for improvement in terms of integrations. We have some tools, such as our off-site Meraki firewalls, that have not fully integrated with Sentinel. We lack integration for Syslogs into Sentinel."
"There are certain delays. For example, if an alert has been rated on Microsoft Defender for Endpoint, it might take up to an hour for that alert to reach Sentinel. This should ideally take no more than one or two seconds."
"Microsoft Sentinel is relatively expensive, and its cost should be improved."
"If you're looking to use canned queries, the interface could be a little more straightforward. It's not immediately intuitive regarding how you use it. You have to take a canned query and paste it into an operational box and then you hit a button... They could improve the ease of deploying these queries."
 

Pricing and Cost Advice

"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 tool's licensing costs are yearly."
"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 free."
"AlienVault OSSIM is free."
"AlienVault OSSIM is expensive compared to its competitors."
"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 the community version, which can be used for free."
"Sentinel is a bit expensive. If you can figure a way of configuring it to meet your needs, then you can find a way around the cost."
"Microsoft Sentinel requires an E5 license."
"Good monthly operational cost model for the detection and response outcomes delivered, M365 logs don't count toward the limits which is a good benefit."
"It is certainly the most expensive solution. The cost is very high. We need to do an assessment using the one-month trial so that we can study the cost side. Before implementing it, we must do a careful calculation."
"Microsoft Sentinel is expensive."
"It is priced fairly given the value that you get from the use of the product. The biggest mistake people make with Microsoft Sentinel is not understanding the pricing model and the amount of data that they are going to be running through the tool because you are paying based on the flow. You are paying based on the amount of data that is moving through the tool. People do not plan, and therefore, they get surprised by the cost associated with using the tool. They connect everything because they want to know everything, but connecting everything is very expensive."
"There are no additional costs other than the initial costs of Sentinel."
"Cost-wise, Sentinel is based on the volume of information being ingested, so it can be quite pricey. The ability to use strategies to control what data is being ingested is important."
