Continuous monitoring has strengthened payment security and now reduces incident impact quickly
There are specific details that can be improved in Deepwatch. After implementing it, we tracked both response time and threat detection accuracy using the SIEM dashboard. We measured response time using MTTD and MTTR. There are areas that can be improved, such as every alert having a timestamp for detection time and acknowledgment. We observed the MTTR dropping from a few hours to under one hour after using Deepwatch, so baseline metrics can be enhanced. Deepwatch can reduce alert fatigue since sometimes it generates a high volume of alerts that overwhelm our team. This can create too many alerts in a short amount of time, making it hard for our team to understand what to do. Additionally, the dashboard can be improved for better user-friendliness for end-users, requiring better visualization of MTTR, threat trends, and risk scoring. Improvements can also be made in more automated playbooks for automated response to common threats, and there is room for deeper integration capabilities, as integration with some internal tools may require additional effort.

Improved threat detection has reduced incidents and has automated investigations with AI
There are multiple features of ReliaQuest GreyMatter which I love personally. The agentic AI, which helps in autonomous investigation and containment, is multiplying the speed of the task to be done. Features such as managed service integration and MDR with human expertise when needed are some major features which I love about ReliaQuest GreyMatter.

Quotes from Members

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

Pros

"Deepwatch positively impacts our organization by reducing incident response time because previously, there was no mechanism to follow up on incidents, such as any security breach in the payment gateway, and it has reduced response time by 40 to 60 percent while significantly improving threat detection accuracy with 24/7 monitoring even after business hours."
"ReliaQuest GreyMatter has helped us to reduce security incidents by 89%, which is a significant amount of incidents we have seen."
"ReliaQuest GreyMatter saves around 60% of time or resources."
 

Cons

"Deepwatch can reduce alert fatigue since sometimes it generates a high volume of alerts that overwhelm our team."
"Areas that have room for improvement include user interface and integration."
