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 So when we move to it, this will be literally outdated.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 The way security is moving, it will be outdated very soon.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.

Easy to set up with good behavior-based analysis but needs a single-click recovery option

Most organizations are currently looking for a scheduled scan to meet their compliance needs. Other players like Symantec and Trend Micro, FireEye, et cetera, are still providing the signature-based regular scheduled scans also, which is not available in CrowdStrike. That is one parameter that we feel should be there in CrowdStrike. CrowdStrike is only working on the dynamic or the files under execution. CrowdStrike is not scanning the static files. The product could be more accurate in terms of performance. We'd like to have a single-click recovery option. With some machines getting corrupted by malware, we need an easy way to start with a blank slate if things happen. That one feature should be there in the EDR.

Quotes from Members

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

Pros

"I recommend it due to the experience of the people running it."

"The most valuable feature is the logging capability."

"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."

"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."

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

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

"The initial setup is straightforward."

"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."

More AlienVault OSSIM pros

"CrowdStrike Falcon's most valuable features are the lightweight agent which has absolutely zero performance issues. There is no performance deterioration on the laptop on the network. It is a signature-less antivirus and anti-malware solution, it doesn't depend on signatures which better protects the systems."

"The features I like the most are the response time and the dashboard are both excellent."

"The DLP is the most valuable feature of CrowdStrike Falcon."

"Enables us to understand what processes are running on the system, what registry keys have been enabled."

"From what we have seen, it is very scalable. We have recently acquired a company where someone had a ransomware attack when we joined networks. Within the course of just a few days, we were able to easily get CrowdStrike rolled out to about 300 machines. That also included the removal of that company's legacy anti-malware tool."

"The most useful feature is that we do not need to install or keep signature files. Regular scanning that consumes a lot of computer resources is not needed."

"Everything is automatic. I install the sensor and renew the service. Periodically, I get a notice that they've shut something down."

"We are happy with CloudStrike's ease of use and touch notification."

More CrowdStrike Falcon pros

Cons

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

"AlienVault OSSIM gives unwanted notifications."

"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."

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

"The incidence reporting could be better."

"The solution is not scalable."

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

More AlienVault OSSIM cons

"The solution could improve the policies themselves."

"The solution should have included remote wipe capability out of the box."

"The new interface, the UI, seems a bit messy."

"The pricing structure should allow for some flexibility."

"It is cloud-based, and this does make some weary of the data being held on the cloud. Privacy requirements must be taken into account."

"This solution could be improved with greater scope for admins to make changes to the solution."

"The solution could improve the policies themselves. It would be helpful if there were cost-cutting measures."

"In the future release of CrowdStrike Falcon, they should add a sandbox feature."

Pricing and Cost Advice

"AlienVault OSSIM is an open-source solution."

"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."

"We are using the community version, which can be used for free."

"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."

"OSSIM is free."

"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."

"AlienVault OSSIM is expensive compared to its competitors."

More AlienVault OSSIM pricing and cost advice

"CrowdStrike Falcon is more expensive than other EDR solutions with similar features."

"We have a yearly subscription and find the price to be good. I'd give it a rating of four out of five for price, we got a good discount."

"This solution offers annual subscriptions. The pricing for this solution could be reduced."

"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."

"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."

"We bought a very small number of licenses, then ran it for a year. We bought a 100 licenses for a year, so we didn't actually do a proof of concept. We just bought them. Then, the next year, we bought 10,000 licenses."

"Annual licensing."

"The cost of CrowdStrike Falcon could be reduced. It is quite expensive if you compare it to other solutions, such as Blue Coat, Symantec, McAfee, or Kaspersky."
