Unified security monitoring has reduced alert fatigue and improves proactive threat hunting
I use real-time monitoring in ReliaQuest GreyMatter, which significantly improves my security posture. The unified interface helps reduce alert fatigue. I would estimate it saves around 20% in alert fatigue reduction. The automated threat hunting capabilities in ReliaQuest GreyMatter help me stay ahead of threats. The machine learning algorithm benefits my threat intelligence by providing deeper insights and predictions. I use various metrics to rate the success of the predictive threat intelligence in ReliaQuest GreyMatter.

Provides innovative security features and accurate real-time threat management
From my reseller and partner perspective, the best features in the products are easy deployment, really small size installation, and an update process. It is a Gartner leader, so there is a lot of innovation in it. Regarding real-time monitoring features, it is absolutely accurate and automatically handled in most cases if configured correctly. I am actually able to synthesize machine learning with human experience to manage complex threats in IRs. This is included as part of the back-office strategy that they run through an AI process. I assess the importance of having 24/7 security coverage provided by SentinelOne Vigilance to be highly needed. As a customer, I have seen benefits from using it, and I can assure that it is 100% protected against many threats, and it is always in the actual state. I have observed improvements in Incident Response speeds since integrating SentinelOne Vigilance, as there are far more incidents automatically detected and cleared than before.

Cons

"Areas that have room for improvement include user interface and integration."
"When upgrades are required on the server, you need to almost remove SentinelOne Vigilance completely off the system."
"SentinelOne Vigilance could improve if it provided us with more control over the dashboard."
"I suspect that the areas for improvement may not necessarily lie within the tool itself but rather in our organization's lack of knowledge and understanding of cybersecurity. Cybersecurity is a complex area, and our organization has a skill set deficit. Therefore, we rely on our cybersecurity support company to help us manage the tool and handle incidents. Our limited expertise sometimes prevents us from fully utilizing them or identifying potential gaps."
"The solution should add endpoint clients for mobile and Linux devices because it currently doesn't support them."
"The toughest challenge that customers find is with the deployment and tuning of the product; getting it tuned properly takes some time, so that's a challenge."
"My customers who use the tool mostly want a summary of the monitoring activities of the product in a report form...t can be useful for our customers to identify the threats and incidents encountered by the product."
"My only complaint is that the knowledge base is not accessible to the customer."
"The support response time is not the issue, however, sometimes, the answers provided are not fully satisfactory due to the nature of the technology and issue complexity."

"I rate the product's pricing an eight out of ten since it is really expensive, but it is well worth what my company gets."
