    Good integration, simple to maintain, and very stable
    Scalability shouldn't be a problem, at least for the size of network team that I work with. Right now we have between 400 and 500 users. This is deployed in a network that is actually about 500 users. We don't plan to increase usage. We're already using it as fully as we can and we don't have any more room. We might look at all the Microsoft programs that relate to office 365, like the ATP, because there is a difference between the ATA and the ATP. We are going to look and see whether there's any gaps that we can close. I think if you compare ATA with the actual ATP it's basically the same functionality. One is more on-premises versus the cloud. Since we are progressively in moving to the cloud, we might look at the ATP, which integrates better with the Microsoft cloud.

    Good value, easy to use, and easy to deploy
    In terms of what can be improved, that is a question I think the end users can tell you better. I'm not the end-user for this system. However, I can say that it needs to be more scalable. I think they already have a good value proposition in terms of being a hybrid model, and the reporting is okay, as well. It could have better integration with other SIEMs, but this integration has to come from the SIEM side, not ObserveIT.

    Quotes from Members

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

    Pros

    "One of the most valuable features is the ability to report on questionable activity."
    "The solution works well when used with other Microsoft solutions."
    "The stability of the solution is very good."
    "It has also measurably decreased our mean time to detect threats by about 50 percent, and helped increase staff productivity, saving about an hour per day."
    "I like the fact that it looks for some of those very, very obscure techniques and attacks like golden tickets; those are very difficult attacks to spot and with Microsoft ATA I was able to have visibility over those kinds of techniques and attacks."
    "Record videos that have a very small file size Management interface is very convenient and intuitive"
    "Overall, it gives a consistent and really good return on investment."
    "ObserveIT is small, easy to use, easy to deploy, and is not complicated, so it's more generally suited for only SMBs. It's a good value with a cheaper price."
    "Meta data search Alert generation."
    "It resolved security issues of the organization by providing audit reports and records to our customers."
    "Customer Service: The ObserveIT professional services team has been excellent, extremely engaged and genuinely concerned with our success."
    "All my clients are very pleased with this product as it helps them to keep track of what partners and employees are doing on the servers."
     

    Cons

    "The software is not as advanced as many competitors."
    "There are occasions where it generates some false positives and you have to embark into figuring it out. You need to find out if it was a true alert or a false positive. It's a little bit cumbersome in that area."
    "It would be ideal if the interface allowed for more granular configurations. For example, if I were to set a rule that is a deviation from the pre-defined rules in the Microsoft product, there's conflict."
    "Some of the newer features are not completely there yet... For example, there's a tool that allows you to grade your overall internal security and I don't feel that it's completely accurate."
    "ObserveIT is not scalable and it's not for the medium to large corporations. It's for the smaller environments. For the larger corporations, we have other scalable solutions."
    "I had some problems with an instance of ObserveIT in a Proof of Concept, when I installed ObserveIT with an SQL Express instance and the DB used all provisioned space."
    "OCR capability, support for Mainframe, Ticketing and Incident workflow."
    "Ticketing and issue management. Based on the new system, one needs to go through the sales people."
    "The tool is still not providing records of tunnels established - we would like to see it in future versions."
     

    Pricing and Cost Advice

    "I believe we are looking into new licenses. They may be called the E5. Honestly, I don't have it on top of my mind, but I think it's around seven to $10 a user per month."
