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.

Enables granular control through Ringfencing and works seamlessly for us as an MSP
The most valuable feature is ringfencing. It enables us to only allow what needs to be allowed into the environment and keep out anything else. It permits applications to perform without accessing anything they are not supposed to. For instance, if an application tries to utilize the command prompt unnecessarily, it blocks this action while still allowing users to operate the application. Being able to let the user or the customer continue to use that application but block the application from using the command prompt because it is not necessary is great. Being able to inform customers about enhanced security from a zero-trust standpoint has significantly improved our sales. We are able to walk up to a customer or call a new prospect and let them know that we are going to keep them secure at a level that they have not seen before. We are able to explain to them how cybersecurity works through it.

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."
"Being able to inform customers about enhanced security from a zero-trust standpoint has significantly improved our sales."
"I believe it is probably the best around."
"There is a tremendous amount that is helpful, such as their recording, watching the systems, locking down the systems, and their training."
"It's an important solution to have in order to maintain a strong security posture, especially as we're seeing things like supply chain attacks, where people are accidentally downloading malware from our vendors."
"ThreatLocker's support and Cyber Heroes have the absolute best support in the industry, in my opinion, bar none."
"It's secure, and we know it's secure."
"The most valuable feature, in terms of protection, is the allowlist, which ensures that only IT-approved applications run."
"The customer service is really good."
 

Cons

"Areas that have room for improvement include user interface and integration."
"Pricing is a bit high, with a minimum of 50 devices. Lowering that for small companies would be great."
"We have seen a couple of approval requests come through where if the user types in a reason for why they need it, they'll get approved based on the reason versus the application that are actually required."
"From an MDR perspective, the solution can have the ability to ingest logs from other sources, such as M365, firewalls, external sources, and even cloud SaaS-based platforms. This way, we can obtain a holistic picture."
"The Cyber Hero Support is not as effective as it is portrayed. There is a lot of miscommunication in notes, which are very buried and not easy to find."
"If there is any aspect to improve, perhaps affordability for small businesses could be considered."
"The ultimate, most amazing solution in the market could be less pricey and more transparent."
"Pricing is a bit high, with a minimum of 50 devices. Lowering that for small companies would be great."
"There are still gaps in the EDR when benchmarked against SentinelOne, but it's improving quickly."
