Microsoft Defender XDR and Zero Trust Security Implementation: 4-8 Weeks Engagement
Celebal Technologies Private Limited
Microsoft Defender XDR (formerly Microsoft 365 Defender) addresses this challenge through a unified Extended Detection and Response (XDR) platform that coordinates detection, prevention, investigation, and response across the entire digital estate. Celebal Technologies implements Microsoft Defender XDR as a centralized AI augmented defense engine aligned with Zero Trust principles. By integrating endpoint protection, hybrid identity security, email and collaboration defense, and cloud app governance into a single operational framework, enterprises gain continuous security visibility, automated threat containment, and machine speed response while simplifying security operations.
What It Offers
- Zero Trust Security Assessment across Microsoft 365 workloads and cloud environments
- Cross-Platform Endpoint Protection Deployment for Windows, macOS, Linux, Android, and iOS
- Advanced Email & Collaboration Security protecting against Business Email Compromise (BEC), QR-code phishing, and malicious Microsoft Teams links
- Hybrid Identity Security Implementation using Microsoft Defender for Identity across on-premises Active Directory and cloud identities
- Shadow IT Discovery & Data Governance through Microsoft Defender for Cloud Apps with session-level access controls
Assessment Scope
Celebal Technologies evaluates the current enterprise security environment to establish an optimized Microsoft Defender XDR architecture.
Assessment Includes
- Gap analysis to map existing tools against Microsoft 365 and eliminate redundancies
- Audit signal readiness validation across Active Directory, email, and SaaS connectors
- Security vendor consolidation strategy aligned with Microsoft security ecosystem
- SOC workflow evaluation to reduce Mean Time to Respond (MTTR) using automation
Core Security Capabilities
- Auto-Containment: Immediate isolation of compromised users and devices to stop ransomware spread.
- Identity Defense: Protection against credential theft and unauthorized privilege escalation.
- SOC Automation: Automatic remediation of up to 90% of alerts, reducing analyst workload.
- Proactive Threat Hunting: Investigation across 30 days of raw telemetry using KQL queries.
AI-Powered Security Operations
- Natural-language investigation using NLP-based security queries
- Automated analysis of scripts and command-line activity
- Guided incident recovery playbooks for analysts
- Automated weekly reporting on threat landscape and security posture
Implementation Approach
Phase 1: Architecture & Security Design
Define RBAC, optimize alert tuning, and establish data retention policies aligned with 2026 compliance standards.
Phase 2: Core Defender Onboarding
Systematic deployment of Endpoint sensors, MDI sensors, and MDO threat protection policies.
Phase 3: Advanced Security Hardening
Configuration of Attack Surface Reduction (ASR) policies, Endpoint Detection and Response (EDR) in Block Mode, and Tamper Protection.
Phase 4: Operational Excellence Enablement
Implementation of SOAR playbooks, custom detections, automation workflows, and Microsoft Security Copilot integration.
Phase 5: Maturity Handover
Delivery of SOC runbooks, Tier 1–3 analyst training, and a 12-month enterprise security evolution roadmap.
Enterprise Outcomes
- 80% reduction in incident response effort
- Up to 60% lower total cost of ownership
- Operational Zero Trust enforcement
- Reduced dwell time
Engagement & Pricing
The final cost depends on deployment variables such as the number of protected seats (identities/mailboxes), total endpoints, and the level of automation and customization required.
