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.

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."
"Our customers now have the confidence that they can work without being impeded, losing access or getting compromised."
"I believe it is probably the best around."
"I did a detailed search for two years, and ThreatLocker Zero Trust is the only one that does what it says it can do."
"The customer service is really good."
"Being able to inform customers about enhanced security from a zero-trust standpoint has significantly improved our sales."
"Customer service and support are exceptional."
"Our clients feel a bit more secure when using their equipment now, and they can feel confident that we have their backs kind of when they're when they either get compromised."
"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."
 

Cons

"Areas that have room for improvement include user interface and integration."
"There are still gaps in the EDR when benchmarked against SentinelOne, but it's improving quickly."
"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."
"As far as an improvement regarding ThreatLocker Cyber Hero MDR, there are still some things that, out of the box, it would be nice to have a more fine-grained ability to create certain exclusions."
"Pricing is a bit high, with a minimum of 50 devices. Lowering that for small companies would be great."
"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."
"It would be great if they handled patch management, and I am aware that they are currently working on it."
"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."
 

Pricing and Cost Advice

Information not available
"It has been excellent."
"The pricing is not so bad. My clients do not like it, but they are following our pricing."
"It is pretty good. We would have been one of the biggest partners in Ireland, so we got pretty good pricing at the start, and it is still competitive. Pricing depends on what we are up against."
"ThreatLocker is worth every penny and a couple more."
