NetFlow Advantage Use Case

NetFlow-Enabled Supply Chain Threat Surface Mapping

See active malicious connections within supplier and partner networks in real time.

Who: CISOs, TPRM leaders, CTI teams, and threat hunters responsible for third-party risk.
What: Active malicious connections inside supplier and partner networks, observed at the flow level.
Why: Third-party compromise sits outside traditional visibility, and you can only defend what you can see.

Why it matters

Why Supply Chain Threat Visibility Is Mission Critical

Supply chain security threats sit outside traditional visibility, highlighting an urgent problem: you can’t defend what you can’t see. With 90% of organizations citing third-party compromise as their top risk, external attack surface monitoring is mission critical.

Leveraging the most comprehensive collection of global NetFlow sources, Team Cymru delivers behavioral evidence of compromise across external networks, giving you maximum visibility before attackers can infiltrate your infrastructure.

We own the only real-time and global view into external supply chain compromise.

How it works

Map Malicious Activity Across Your Entire Supply Chain

With the world’s most extensive collection of raw NetFlow data sources, Team Cymru exposes the supply chain cyber security threats that go unseen by traditional cybersecurity tools.

Real-Time Supplier Monitoring

See which suppliers are talking to known threat actor infrastructure within minutes.

Flow-Level Compromise Detection

Spot scanning, staging, and C2 callback activity across global networks in real time.

Cross-Supplier Threat Mapping

Trace lateral infections and links between compromised vendors and attacker systems.

What it reveals

What NetFlow Reveals About Supplier & Partner Compromise

Behavioral Threat Indicators

Who uses it

How Teams Use Supply Chain Threat Flow Data Today

CISOs & TPRM Leaders

Prioritize third-party risk in real time. Identify compromised suppliers before they become attack vectors. Validate vendor security posture with live behavioral evidence rather than static questionnaires.

CTI Teams

Confirm supply chain security threats and map attacker infrastructure across vendor networks. Correlate real-time raw flows with historical behavior to uncover hidden attacker activity.

Threat Hunters

Build preemptive defenses to block malicious vendor communications. Detect reconnaissance, staging, and lateral movement using raw source insights instead of filtered threat assessments with inherited vendor bias.
