Cloud monitoring has reduced threats and has improved response times and team productivity
Alert Logic MDR's best features are the cloud-managed service, the cost benefit, and 24/7 monitoring. The alert system improved from potentially 24 hours to one hour response time. The benefit of not having to write custom queries has been significant.The features are very lightweight, with small installations that leave almost no footprint on systems. System resource utilization is minimal. Alert Logic MDR has positively impacted my organization through its decentralized pricing approach, which has protected against several viruses. Any virus stopped represents money saved. There is low impact on users, so they do not experience slowness on their computers when scanning. Alert Logic MDR has improved security in my organization from 50 to 65%.

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.

Quotes from Members

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

Pros

"The solution was consistently available, and I cannot recall any instances where it was down."
"Alert Logic MDR's best features are the cloud-managed service, the cost benefit, and 24/7 monitoring."
"The value of Alert Logic is that everything is in one dashboard; I'm notified when there's an incident, kept up to date and advised on what steps to take."
"My advice would be to go ahead with the product because it really is a very good tool that adds a lot of value."
"It has the ability to install agents, it is pretty straightforward, and you can automate the process pretty easily."
"I would definitely recommend Alert Logic because it is a good product that constantly adds new features and changes interfaces."
"We receive infrastructure security warnings from it. So, we know what is going on and what needs to be addressed."
"The most valuable aspect of Alert Logic is its technology platform. They have SOCs in the US and Europe, giving them global visibility of the threat landscape. They detect and respond to threats in minutes. Their biggest value is human expertise. You're being attacked by a human, and you cannot respond to it unless you have a human on the other side. They have the human and technological resources to respond."
"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

"This product needs to mature more. While it is a good product, there are some areas where it needs work."
"Alert Logic MDR stops programs from making changes to user systems, though this can be hit or miss."
"One major missing feature was the ability to see if vulnerabilities were exploitable, which required extra effort for us."
"I think Alert Logic MDR could be improved."
"I would like more data on the alert payload. It would be good to have the ability to customize the alert payload to add whatever data that we want on there. Right now, it is a bit limited."
"I would like to see it do initial scans and start capturing data, which it will truly analyze, not just be a reporting system saying, "Here is an email. Here is an email. Here is an email.""
"Our ROI would probably be zero. We don't even use it."
"We'd like to have triggered alerts sent to us so we see errors quicker."
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"Its pricing is very reasonable considering what you get for what you pay. There is quite a good value there. Its licensing is also very logical. They've got the licensing price points at a reasonable level. It is on a monthly license but a yearly contract. There are no additional costs to the standard licensing fees."
"Our ROI would probably be zero. We don't even use it. It sits in there. We get emails and just delete them. Around the world, we don't even use it."
"Almost any product that is on the AWS Marketplace is super easy to subscribe to."
"Price of the solution was very reasonable considering the size of our organization at the time, and so it worked out perfectly."
"Alert Logic has better competitive pricing than some of its competitors."
