An easy-to-scale open-source solution used for monitoring events on devices

The area for improvement is a lot. When I started using it on our enterprise side, the issue we faced was, for example, if we were running at that time on AlienVault OSSIM v5.7.4. So, for some orders, we had to install some packages, and when we tried installing that package, some dependencies got upgraded to a new version. Now once that dependency got upgraded, the SQL, since you might be aware that OSSIM uses SQL database, now SQL and all the dependency in everything was not on the same version, and that caused the database to crash. The aforementioned area should be eased out by upgrading the patches and upgrading dependencies. This kind of thing is a disadvantage of OSSIM, and I would like them to work on this. But I have also raised service requests many times and gave it a push on the community section too. However, since it is a local source, they don't reply much over there. That is why I don't like to work on OSSIM because it is unpredictable. Once the storage goes above 50 percent, it starts behaving unpredictably. If you get stuck with a situation, then you need to drill a lockdown into that. Sometimes you get no luck. Then you have to just reimage the server with the new fresh OS of AlienVault. As for additional features, not much because if you move to the newer version, it is kind of getting more stable. But, to make my life easier, then I would say try to give more features. I know it's open source, so they also cannot provide me with more features. But still, if they can provide me with more features because right now it's becoming old. Right now, we are even moving from SIEM to Security Data Lake. So when we move to it, this will be literally outdated. No one can even expect anything out of it. The way security is moving, it will be outdated very soon. They have to also provide something new to keep this going for the future also.

Provides effective real-time threat detection with potential for cost optimization

Some features such as device control, firewall management, and file analysis are standalone products that we need to purchase separately. If these features came out of the box within the product, it would be much more beneficial for us. Other providers such as SentinelOne include these features in their base product. We attended a CrowdStrike Falcon event where they discussed some shallow AI features, but we cannot see these in our panel yet. We work with different solutions such as Darktrace and SocRadar, where AI features are automatically displayed in our dashboards after release. However, for CrowdStrike Falcon, we cannot see these features.

Quotes from Members

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

Pros

"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."

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

"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."

"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 product is easy to use."

"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."

"Better than other SIEM solutions because almost everything can be integrated."

"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."

More AlienVault OSSIM pros

"The real-time analytics aspect of CrowdStrike performs well because we get all logs in real-time, with no delay, allowing us to take action immediately."

"CrowdStrike Falcon's most valuable feature is the fact that it's not getting in the way of our workforce and their workflow."

"The most valuable features of Crowdstrike Falcon XDR are Spotlight and Discovery, they are helpful. Additionally, the console is user-friendly, with fewer false positives than other solutions."

"It is an easy product to deploy."

"The solution has improved my organization by automating the detection and reporting of unwanted applications so we're aware of them and can respond appropriately."

"The most valuable feature is the activity dashboard because it gives you a holistic view of your environment from a security standpoint."

"I like the detection rates of mobile threats."

"We have a small IT Team, and this allows us to get sleep at night, knowing that someone else is taking care of any incidents that occur."

More CrowdStrike Falcon pros

Cons

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

"The correlation engine needs to be improved."

"The price of this solution is very high and it could be cheaper."

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."

"The incidence reporting could be better."

"It's so hard to configure and explore something new on it."

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

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

More AlienVault OSSIM cons

"The management of log aggregation is in need of improvement."

"For CrowdStrike to work, all the machines need to have an internet connection. This makes it challenging to assist customers without an internet connection. We would like to have a mechanism or relay to make this possible."

"Some of Falcon's features are a bit pricey."

"CrowdStrike Falcon could be enhanced by extending its security capabilities to include NDR and XDR."

"The skillsets needed to run CrowdStrike Falcon are extensive if you want to get the most value out of the tool."

"I would rate it an eight out of ten. It does what it needs to do but there's always room for improvement."

"I think there's an opportunity to enhance the AI or at least the traps to say, if something changes from this baseline, let us know and flag it."

"As for stability, I would rate it around eight because last year they faced some downtime with around eight thousand computers, but it will improve."

More CrowdStrike Falcon cons

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."

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

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

"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."

"The tool's licensing costs are yearly."

"AlienVault 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."

More AlienVault OSSIM pricing and cost advice

"The price of CrowdStrike Falcon could be better. It is very expensive, we pay approximately $900 per month for the licenses. There are not any additional fees."

"The other administrator and I can log in to check the exact details of what happened, what was running, and what caused the detection. We know exactly what was happening on the end users PC and we can tell if it's something that we actually need or something that's malicious."

"Years ago, when we bought CrowdStrike, you got everything it had. I was a little concerned when they broke this out into a la carte modules where you can buy EDR, Spotlight, etc., picking and choosing off the menu. I was a little worried that the solution would get watered down. However, I realized in my previous organization when we had the full suite that there were a bunch of features in it that we didn't have time to operationalize. So, I warmed up to it. I get the whole, "Look, you can pick and choose. Okay, everybody buys a steak, but do you want mashed potatoes, or do you want lobster mac and cheese?" So, you can pick the sides that you want, so you can buy the solution that you want and operationalize versus paying a lot of money and getting a bunch of things, but not using 60 percent of the tools in the box."

"The pricing and licensing are reasonable. I don't think we are getting charged more than what it is worth. It is fair, but I do not like how it is a la carte. I realize they do that so other organizations can buy and get the agent, getting it cheaper than you could otherwise. However, if you want the main core package, which has all the main features with the exception of maybe the multi-cloud protections, that can get pricier for an organization. So, you have to pick and choose what you want. I do not care for a la carte pricing."

"The cost of CrowdStrike Falcon in Latin America seems high relative to the economic conditions in the region."

"I'm not directly involved in sales, so I can't comment on the exact price, but I know the price decreases the higher the quantity we purchase."

"There are approximately a hundred different modules you have to purchase, depending on what you want to do. I have most of the modules. How it works is you buy the portfolio, you have to decide all the components you want in it, and then they price out a bundle for you. I have almost all of the package features in my bundle. You only need to pay for the modules you want."

"When comparing to Microsoft, CrowdStrike Falcon is more expensive."
