I also like ReliaQuest’s track record—it feels like a solid company with a deep focus on cybersecurity. Overall, everything is automated, accurate, and straightforward, and honestly it saves my team hours every month. Review collected by and hosted on G2.com.

They’ve been consistently updating their services, and I’ve really liked the dark web monitoring and the 24/7 vulnerability scanning. I haven’t run into any issues or problems so far, and I honestly don’t have anything negative to say—I love everything about it. Review collected by and hosted on G2.com.

"Responsive Control Panel with Clear Reporting and Expert Alert Optimization"
5/5
What do you like best about ReliaQuest GreyMatter?

I love the control panel—it provides clear reports on any activity, and its responsiveness has been excellent. The team helps optimize alerts and is highly qualified. I also really appreciate how many technicians they have, since it has reduced false positives. Overall, there have been very few system interruptions. Review collected by and hosted on G2.com.

What do you dislike about ReliaQuest GreyMatter?

When I’m handling large volumes of data, searches can feel slow, and fine-tuning can take a lot of time in more complex environments. I’ve also found customization to be complicated at times, and I’d like the option to add more services more easily. Review collected by and hosted on G2.com.

"Clean, Easy-to-Use Interface with Proactive Monitoring and a Great Visual Map"
5/5
What do you like best about ReliaQuest GreyMatter?

I really like the visual map—it’s great for understanding how things are distributed. It also gave us confidence that, in a real incident, we’d have staff actively monitoring and taking action, rather than just a dashboard full of alerts that we’d have to prioritize ourselves. On top of that, the interface feels cleaner and easier to use than Microsoft’s security portal. Review collected by and hosted on G2.com.

What do you dislike about ReliaQuest GreyMatter?

Setting it up was easy, and the integration with our team has been excellent—they’re always available when we need them. It gives us real peace of mind knowing our systems are in good hands, even when we’re offline. Review collected by and hosted on G2.com.

"Seamless Setup, Excellent UI, and Powerful Threat Detection"
5/5
What do you like best about ReliaQuest GreyMatter?

Setup was straightforward, and the user interface is excellent. It also includes several features I really love. I especially appreciate how seamlessly it connects with my existing security tools to provide comprehensive protection. For threat detection, I’ve found it to be excellent, and its AI agents and broad visibility helped reduce incidents by 89%. Review collected by and hosted on G2.com.

What do you dislike about ReliaQuest GreyMatter?

It is compatible with different environments, which allows for a more customized implementation. Its ability to adapt to the specific needs of each sector, as well as to regulatory requirements, makes it a versatile option for use across a wide range of settings.

"Streamlines Incident Management with Ease"
4.5/5
What do you like best about ReliaQuest GreyMatter?

I appreciate ReliaQuest GreyMatter for providing a single pane of glass across every appliance we monitor. The AI summary attached to each raised incident is what I lean on most, as it arrives in plain language with the relevant data already assembled, which helps my analysts avoid piecing context together while time is of the essence. The onboarding went more smoothly than I anticipated, mainly due to a knowledgeable team. Integration with Microsoft Defender, Sentinel, Palo Alto firewalls, and AbnormalAI went smoothly without any friction. I also value the custom rules deployed on our behalf that flag activity missed by other platforms. Review collected by and hosted on G2.com.

What do you dislike about ReliaQuest GreyMatter?

The Android application feels less polished than the rest of the product, particularly at sign-in. I appreciate that iOS carries the larger share of users, though those of us on Android would welcome some attention here. Biometric sign-in that holds the session for a reasonable window would help most, since re-authenticating from scratch every time an alert lands is the part that slows me down when I am responding away from my desk.

What do you dislike about ReliaQuest GreyMatter?

Sometimes there are so many alerts that it becomes overwhelming and creates a lot of noise. This alert overload can be an issue, and at times it’s also confusing to figure out where certain items are located. Review collected by and hosted on G2.com.
