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.

Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

Quotes from Members

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

Pros

"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."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"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 would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
