How Major Telecom Provider NOS Reduces Cyber Risk and Investigates Threats with Censys

Telecom and technology providers like NOS are prime targets for cyberattacks. Managing approximately 2 million IP addresses and critical infrastructure, NOS needed a way to enhance their security posture and protect their brand.

The Challenge: A Complex and Expansive Attack Surface

NOS’s environment includes cloud services, IoT systems, and emerging 5G infrastructure, making it vital to identify unknown exposures and prioritize high-risk vulnerabilities. Existing security tools created overwhelming alerts and false positives, leaving critical risks unaddressed. NOS needed a centralized solution to cut through the noise and guide real-time remediation efforts.

The Solution: Censys Attack Surface Management and Censys Search

Censys provided NOS with superior visibility into their attack surface and threat landscape. By aggregating data from internal, cloud, and customer-facing environments, Censys enabled NOS to:

  • Uncover unknown exposures and close security gaps.
  • Respond to vulnerabilities like the OpenSSH CVE in real-time.
  • Secure their ecosystem, including third-party partners, from ransomware and other attacks.
