Case Study: Magna5 thwarts Cobalt Strike intrusion and strengthens client protection with Huntress

How Huntress caught an elusive threat actor’s bid to gain control where SentinelOne missed

Magna5, a managed service provider serving over 700 clients, faced a midnight intrusion attempt when Cobalt Strike was used to gain remote access through an unpatched SonicWall VPN appliance on a non-domain Windows 10 machine. While Magna5 had SentinelOne deployed, Huntress — using its Managed EDR/Managed Security Platform and 24/7 SOC — detected the attack and provided the origin and context that other EDR tools missed.

Huntress immediately isolated the affected machine, identified the vulnerability and alerted Magna5, enabling rapid remediation and preventing a full takeover; the Huntress deployment took minutes and began surfacing issues other solutions overlooked. By bundling Huntress with SentinelOne and leveraging Huntress’s continuous SOC support, Magna5 mitigated subsequent threats (including a BlackBasta execution) with no client impact, improving detection coverage and reducing time-to-remediation.
