The speed of onboarding was a delightful surprise. In times where integrating new systems can take weeks, UnderDefense had us up and running in no time. Their 24/7 detection and response service is fast and comprehensive, providing us with a granular, real-time view of our environment. What’s even more reassuring is that now, when alerts pop up, there's no panic. With their guidance, we know precisely what steps to take next. Review collected by and hosted on G2.com.

"Impressed by the 30-day Impact Report"
5/5
What do you like best about UnderDefense MAXI?

Building our cybersecurity from scratch felt like a daunting challenge. Enter UnderDefense MAXI and its 30-day impact report.

The real-time threat updates from UnderDefense MAXI are solid. But what really caught my attention was their rapid response time.

And the transition to integrate with our cloud setup was extremely smooth, without any business interruption at all. Review collected by and hosted on G2.com.

What do you dislike about UnderDefense MAXI?

Some of the features and terms threw me for a loop. But after rolling up my sleeves and getting some guidance from their support, it all clicked. Review collected by and hosted on G2.com.

"UnderDefense has changed our approach to security"
5/5
What do you like best about UnderDefense MAXI?

They have an exceptionally talented team who is very engaged and provides extra care. If I had to pick a single word - I would call them proactive. They keep us informed, suggesting relevant and cost-effective security improvements and new use cases that enhance our defenses. And we love the monthly report - we gain valuable insights into security posture and incidents, and share them with the board of directors. Plus, their expert management of our SIEM has added to the value of our security investments and tools. Review collected by and hosted on G2.com.

What do you dislike about UnderDefense MAXI?

Maybe just the fact that we're working on syncing schedules between their Team Leads and ours. But they're really accommodating about resolving it. I'm sure we'll figure it out. Review collected by and hosted on G2.com.

"Easy and trustworthy vendor"
5/5
What do you like best about UnderDefense MAXI?

What we love most about UnderDefense is their proactive approach. Their experienced SOC engineers work closely with our team, providing continuous monitoring and threat detection. They're always on the lookout for potential vulnerabilities and take swift action to address them. Our systems are protected around the clock, giving us ultimate peace of mind.

The seamless integration and optimization of the EDR platform, CrowdStrike, has been impressive. Despite the complexity involved, they delivered the deployment to 1200 endpoints in just 23 business days. They worked closely with us to ensure minimal disruption to our critical operations. Their communication throughout the process has been excellent. Review collected by and hosted on G2.com.

What do you dislike about UnderDefense MAXI?

Every superhero has room to grow, and UnderDefense is no exception. We'd love to see a more streamlined customization process that reduces implementation time and unlocks even greater value for us. They're already incredible, but a little fine-tuning never hurts. Review collected by and hosted on G2.com.
