Overview

A conglomerate-scale cybersecurity challenge

Doğuş Teknoloji is the technology arm of the Doğuş Group — a conglomerate operating across automotive, construction, media, hospitality, real estate, energy, and technology sectors. With hundreds of companies and tens of thousands of employees, the cybersecurity challenge was uniquely complex.

The security team established three clear primary objectives:

1 – Reduce the attack surface Identify and eliminate vulnerabilities across the vast digital estate through regular assessments and strong access controls.

2 – Elevate security control efficacy Implement and continuously validate best-practice security controls, from intrusion detection to dark, deep, and surface web monitoring.

3 – Focus on critical risk remediation Prioritize vulnerabilities that pose the greatest risk to operations, addressing them promptly to minimize business impact and ensure continuity.

Challenges

Why traditional security wasn’t enough

Sprawling attack surface: Securing hundreds of entities across seven industries meant a constantly expanding and shifting digital perimeter.

Alert overload & slow response: Manual threat processing led to days-long response times, leaving critical windows of exposure open.

High false positive noise: Security teams were spending valuable time chasing false alarms instead of addressing genuine threats.

Prioritization gaps :Without clear risk prioritization, critical vulnerabilities risked being buried beneath lower-priority alerts.

The Complexity

Scope of the challenge

Securing a conglomerate like Doğuş Group is not a standard enterprise security challenge. It is an ecosystem challenge — where hundreds of companies, each with their own digital footprint, must be protected under a unified, scalable strategy.
