Identity Security
Overview
Identity-based attacks have become one of the most common ways attackers gain access to an organization. Defender for Identity helps you detect suspicious authentication activity, compromised accounts, lateral movement, and privilege escalation before they turn into a larger security incident. By monitoring your identity infrastructure and correlating signals with the rest of Microsoft Defender, it gives your security team the context they need to respond quickly.
When we implement Defender for Identity, we start by understanding your identity architecture and administrative model. We work with your team to deploy the required sensors, validate health, and ensure identity signals are flowing correctly into Microsoft Defender XDR. From there, we tune detections, review Secure Score recommendations, and help establish processes for investigating and responding to identity-related alerts.
The end result is better visibility into your identity environment, faster detection of suspicious behavior, and greater confidence that compromised credentials or privileged accounts won’t go unnoticed.
Methodology
At Nubrix Security, we take a structured and collaborative approach to every engagement. Whether we’re improving identity, securing endpoints, protecting data, or optimizing licensing, our goal is to deliver clarity, reduce complexity, and help you take measurable steps forward.
We follow a Crawl → Walk → Run model that adapts to your organization’s maturity, ensuring changes are adopted safely and without disruption.
