Microsoft 365 Solution
Endpoint Security
Overview
Endpoint security in Microsoft 365 really comes down to getting the most out of Defender for Endpoint. It gives you AV, EDR, attack surface reduction, web control, and visibility into what is actually happening on your devices, instead of relying on a mix of tools and one-off policies.
When we work with customers on endpoint security, we start with the basics: what tools you use today, how devices are managed, and what level of control your team is comfortable with. From there, we design a Defender for Endpoint setup that fits your environment, including onboarding, baselines, attack surface reduction rules, and clear processes for handling alerts.
The goal is simple: harden your devices, reduce noise for your team, and give you a single place to see and respond to endpoint threats, without making life harder for your users.
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.
