Your Questions. Answered.
Do you have a question we haven’t covered below? Please get in touch. We also offer Free 1:1 Cyber Consultations with our Security Experts.
What’s the difference between MDR and MXDR?
Managed Detection & Response (MDR) is typically an endpoint-centred managed detection and response.
Managed eXtended Detection & Response (MXDR) extends that across endpoints, identities, email, SaaS and cloud workloads using an XDR platform that correlates signals and coordinates response.
Microsoft defines XDR as a unified incident platform using AI and automation, which MXDR providers like CyberOne then operate for you.
What are the key benefits of Microsoft Sentinel in MXDR?
Cloud-Native SIEM + SOAR With Fast Time-to-value: Sentinel is a cloud-native security information and event management platform with built-in automation, recognised as a Leader in Gartner’s 2024 Magic Quadrant for SIEM.
Proven ROI. Forrester’s Total Economic Impact (TEI) study reports a 234% ROI for a composite organisation adopting Microsoft Sentinel.
Cost Control at Scale: Commitment tiers can reduce analytics-tier ingestion costs by up to 52% versus PAYG and the Sentinel data lake is designed for cost-effective ingest and retention of large volumes.
Unified Operations With Defender XDR: Native integration allows SecOps to manage Defender XDR and Sentinel incidents together in one experience, minimising tool-switching while maintaining SIEM-grade analytics.
What are the key benefits of Microsoft Defender XDR?
Unified View & Response: One portal to see, investigate and act across devices, identities, email, Microsoft 365 and SaaS. It integrates natively with Microsoft Sentinel for an end-to-end XDR+SIEM model.
Built-In Automation: Automated investigation plus automatic attack disruption to contain active threats and cut dwell time and analyst effort.
Independently Recognised: Microsoft is a Leader in The Forrester Wave: XDR Platforms (Q2 2024) and a Leader in the 2024 Gartner Magic Quadrant for Endpoint Protection Platforms.
Proven ROI: Forrester’s TEI study reports a 242% ROI for a composite organisation using Microsoft Defender.
Does Microsoft have enough “signals” to power high-quality detections?
Yes. Microsoft reports 78 trillion security signals per day, informing its detections and insights, drawn from the cloud, endpoints and the partner ecosystem.
Do we need Microsoft 365 E5 to use this?
No. We design around your licences and deliver the best value. Sentinel is available in the Microsoft Defender portal even without Defender XDR or an E5 licence and we help you map capabilities to what you own.
How do you help control Microsoft Sentinel ingestion costs?
By right-sizing ingestion and retention (Analytics vs Basic tiers), applying commitment tiers for predictable savings and reviewing usage with Azure cost analysis.
We also tune noisy rules and split low-value logs appropriately. Depending on data retention, Sentinel Data Lake can optimise costs further.
How quickly can we get to steady state?
Most programmes reach steady state in 2–6 weeks, depending on data sources, approvals and any required hardening. We agree on key milestones, playbooks and KPIs up front.
