Advantage

Why Microsoft Integrated Security?

The advantage of a single integrated ecosystem instead of 5-10 independent security products.

Single Panel Visibility

The Microsoft Defender XDR portal consolidates alerts from all security products into a single panel. Endpoint, email, identity and cloud application events are connected with automatic correlation.

Automatic Investigation & Response

When a phishing email is detected, the system automatically quarantines the email, scans the devices of users who click, checks for credential leakage, and locks affected accounts — within minutes.

Total Cost of Ownership (TCO)

Instead of separate EDR + email gateway + CASB + IAM + SIEM licenses, all security layers are in a single subscription with Microsoft 365 E5. 243% ROI in 3 years according to Forrester TEI research.

65 Trillion Signals

Microsoft analyzes 65 trillion+ security signals daily — including Windows, Azure, Microsoft 365, LinkedIn, Xbox, and Bing. This depth of threat intelligence is at a scale that no 3rd party manufacturer can reach on its own.

Answers

Frequently Asked
Questions

How is Microsoft Defender for Endpoint different from traditional antivirus software?
Traditional antiviruses work signature-based and block only known threats. Defender for Endpoint also detects zero-day threats with behavioral analysis, machine learning and cloud-based threat intelligence. It also offers post-attack investigation, automatic remediation and threat hunting capabilities with EDR (Endpoint Detection & Response).
Should we choose Microsoft 365 E3 or E5 in terms of security?
E3 meets basic security requirements: Intune, Entra ID P1, conditional access, and Defender for Endpoint P1. But if advanced threat protection (EDR, identity attack detection, CASB), advanced compliance (Insider Risk, eDiscovery Premium) and SIEM integration are required, E5 is a must. Alternatively E3 + separate security add-ons can be purchased, but generally the overall cost of E5 is more advantageous.
Can we switch from our current 3rd party security products to Microsoft?
Yes. We migrate from products such as CrowdStrike, Symantec, McAfee, Proofpoint, Okta to the Microsoft security ecosystem. Process: current security posture assessment → Microsoft Defender configuration → parallel execution process → phased migration → deactivation of legacy product. There is no security gap during the transition process.
What is Microsoft Sentinel and why do we need it?
Microsoft Sentinel is a cloud-native SIEM (Security Information & Event Management) and SOAR (Security Orchestration, Automation & Response) solution. It collects logs from all security sources (Defender products, Azure, 3rd party), detects threats by correlating with AI, and runs automatic response playbooks. Even if there is no SOC team, it carries out security operations with automatic research and correction. It is ready for immediate use with 350+ ready-made data connectors.
What is Security Copilot and how does it work?
Microsoft Security Copilot is a GPT-4 based AI assistant that dramatically reduces the workload of security analysts. It can perform incident analysis by asking questions in natural language ("How many login attempts have there been from this IP in the last 24 hours?"), create KQL queries, prepare vulnerability summaries and speed up incident response processes. It works integrated with all Microsoft Defender products and Sentinel.
How does Microsoft 365 help with KVKK / GDPR compliance?
Microsoft Purview offers comprehensive tools for KVKK and GDPR compliance: personal data classification with sensitivity labels, data leakage prevention with DLP policies, legal retention requirements with retention policies, legal research support with eDiscovery, compliance score and action recommendations with Compliance Manager. Microsoft offers the option to keep your data in data centers in the European region (EU Data Boundary).
