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.

Customers have found quick incident response and proactive security management through effective threat detection
Secureworks Taegis Managed XDR MDR is a great product that has not posed any challenges from my perspective. I am extremely happy with the quick response from the Secureworks team. After the Sophos merger, I look forward to seeing a better and more enhanced version of the product. The team does a phenomenal job with automatic maintenance.

Quotes from Members

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

Pros

"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."
"There are some patent pending detectors within the platform that provides a lot of value."
"It provides more visibility and more control over endpoints. It reduces the noise. It clears things and only shows things that are really important. It only shows those things that need to be looked at or need to be investigated further. Other similar solutions give you a lot of alerts and other things, but Secureworks gives you a defined or less noisy view so that you can work or focus on things that are important in terms of investigation, response, and remediation."
"The solution is great for managing alerts and dealing with them as they arise."
"This solution gathers the information logs from all devices and correlates all the information. It notifies us of any critical events taking place across our networks which has been valuable."
"The pricing is flexible."
"Securworks' threat intel seems pretty decent, and they integrate with several solutions we have, such as Azure AD, so all our Microsoft 365 stuff is covered."
"We can easily isolate affected machines in the network."
"The knowledge base is up to date and easy to use."
 

Cons

"Areas that have room for improvement include user interface and integration."
"I would rate the scalability at 50%. We have been having a problem as we are shifting from a previous appliance to a virtual machine."
"The integration with the Carbon Black sensor could be better. ManagedXDR doesn't seem to know how to extract the forensic data from an endpoint that was quarantined by Carbon Black."
"Secureworks Taegis ManagedXDR's query language and stability need improvement."
"This solution could be improved with a higher degree of automation such as automated emails, triggers and defining the severity of the cases."
"Tamper-proofing or tamper protection is still pending in Secureworks."
"In terms of ROI, I'd be surprised if there is any investment return on the SIM."
"The integration would look better with other products, with other EDRs, with other firewalls, with other older versions of firewalls, and the versions of software and hardware."
"In the next release of this solution, I would like to see file integrity monitoring."
 

Pricing and Cost Advice

Information not available
"The pricing for this solution is reasonable. One agent costs approximately 270 dirhams/70 USD for one year. There is a reduction in cost per licence as the number of licences used increases."
"The Red Cloak agent is free."
"Initially, the cost was going to be something around $160 or $170. And eventually, I think they brought it down to $110 and they also threw in some endpoint protection platforms."
"The price is kind of on par. The licensing was comparable to other solutions. It's not particularly high or low."
"It is expensive but there is no better product than this."
"The pricing of Dell Secureworks is very reasonable."
"Secureworks Taegis ManagedXDR is very expensive and could be more cost-effective."
