The Visibility Asset

The source is the advantage

Team Cymru's advantage begins with proprietary visibility into how traffic actually moves across the internet. That global NetFlow foundation is fused with 60+ additional data types and strengthened by trusted relationships across the defender community. The result is a connected view of infrastructure, relationships, history, and behavior that scanners, commodity feeds, and traditional intelligence platforms cannot replicate.

NetFlow elevates everything around it. Our Proprietary data is the foundation that turns information into intelligence—and intelligence into action.

The Netflow+ Story
Signal Rises
L5
Investigation‑Ready Intelligence

Connected observations become answers defenders can act on: infrastructure identified, behavior understood, evidence assembled. This is the layer where an alert becomes an answer, and where an answer becomes a decision a team can defend.

L4
Connected Infrastructure & Behavior

IPs, domains, ASNs, and certificates connect into infrastructure. One indicator becomes a campaign: shared certificates, sibling domains, staging hosts, and 2,000+ behavioral tags showing how it communicates, changes, and prepares.

L3
60+ Fused Data Types

Enrichment gives the movement meaning for decision-making. Every observation arrives with history, reputation, and relationships already attached.

Global NetFlow Visibility

How traffic actually moves across the internet: 400B+ connections observed daily, beyond any single perimeter. Visibility no one can scan for, and no other single vendor can reproduce.

L1
Trusted Data Relationships

How traffic actually moves across the internet: 400B+ connections observed daily, beyond any single perimeter. Visibility no one can scan for, and no other single vendor can reproduce.

Observed movement. Connected context. Intelligence defenders can act on.

Scanner
Shows what is exposed.
Traditional threat feed
Provides indicators collected from multiple sources.
TIP or dashboard
Organizes existing intelligence, alerts, or records.

Partial views become one connected view: how infrastructure communicates, connects, and changes across the internet.

Access to the Advantage

Visibility is the advantage. Access puts it to work.

Seeing what's developing only matters if your people can act on it. Visibility this deep used to demand rare expertise and hours of manual pivoting. Command changes that, with AI woven through the work: every defender gets access to the internet's infrastructure in plain language, follows the connections, and acts while the answer still matters.

1

Ask in plain language.

Questions that once took a senior hunter a day of pivoting come back connected, sourced, and ready to brief.
2

Agents take the repetitive pivots.

Enrichment, correlation, and swivel-chair lookups run on their own, inside Command and inside your stack.
1

Analysts keep the judgment calls.

People spend their attention deciding what matters and protecting what's theirs to protect. That's the time given back.
Act Inside Command

Pure Signal Command

Pure Signal Command™ is access: one unified, AI-assisted environment where an alert becomes an answer. Search, pivot, enrich, connect, and act without losing context or momentum. Less time reconstructing what happened. More time changing what happens next.

  • Unified investigation environment
  • Connected infrastructure context
  • Search, pivot, and enrichment workflows
  • AI-assisted investigation
  • Historical and real-time intelligence
  • Operational dashboards
  • Continuity from signal to action
  • Day-one intelligence, no training period

Extend Command everywhere work happens

Access extends beyond the analyst. It reaches the agents too.

The same access that powers Command extends into everything you already run. Command's intelligence reaches the tools, assistants, and agents your team lives in, so nobody has to leave their workflow to act on what's coming.

The Operational Advantage

Visibility creates time.
Time changes outcomes.

Access creates visibility. Visibility creates time. Most security tools begin working after something has already happened; Team Cymru gives defenders access to infrastructure and behavior while threats are still developing. Follow both timelines below and watch when they end.

The critical difference is where in the threat lifecycle awareness begins.

What Your Team Gets Back

That time compounds into outcomes people can feel: customers protected, critical systems kept available, fraud prevented, financial loss avoided, revenue and reputation preserved, and public services running. Human lives stay protected, and defenders get to spend their attention on the work that requires judgment.

Less manual investigation

Enrichment and correlation arrive done, not assigned.

Less swivel-chair analysis

One thread of context instead of six disconnected tools.

Faster pivots

Indicator to infrastructure in moments, not afternoons.

Earlier answers

Questions resolved while decisions can still change.

Less uncertainty

Provenance-rich context behind every call you make.

More confident prioritization

Know what matters most before it proves it the hard way.

Earlier disruption

Block and dismantle while it is still their problem, not yours.

More time for proactive defense

Attention returned to work that requires human judgment.

Most people will never know what was prevented...but you will.
That is the point.

Built for the Defender's Table

Built for the teams responsible for what happens next.

Every team feels the threat from a different seat. Pick yours to see the problem we solve, what the visibility reveals, how you access it, and the outcome it changes.

For AI, Automation, and Engineering Teams

Give your tools and agents intelligence worth acting on.

The problem

AI systems and automated workflows are only as useful as the data and context they can access.

What Team Cymru reveals

Deliver structured, trusted, provenance-rich internet intelligence through APIs, MCP, integrations, skills, playbooks, and agentic workflows.

The outcome

Automation grounded in differentiated visibility rather than commodity data.

The Global Defender Community

Visibility is built through trust. Trust is returned through action.

For more than 25 years, network operators, CSIRTs, law enforcement, and researchers have trusted Team Cymru with what they see. That trust becomes the visibility behind Pure Signal. And through the Global Defender Exchange, it flows back out as protection: no-cost services keeping networks online, coordinated action taking criminal infrastructure apart, and stolen money finding its way home to real people. The community that makes the visibility possible is the community it protects.

Protected

Hospitals stay online.

When ransomware targets a critical care system, the exchange catches the early signal so patients keep getting treated.

Protected

Schools keep teaching.

When a phishing wave hits a district, defenders inside the exchange see it coming and shut the doors before students lose a day.

Protected

Families keep their savings.

When a fraud operation spins up, the exchange traces infrastructure across continents so law enforcement can stop it before the next family is targeted.

Read the Story

Access is the advantage.
Time is the outcome.

Somewhere right now, an attacker is building the infrastructure for someone's worst day: a hospital's systems, a family's savings, a city's lights. For more than 25 years, Team Cymru has stood with the people whose job is to make sure that day never comes, giving defenders access to what's forming, the context to understand it, and the time to change how the story ends. Most people will never know what was prevented. Your team will.
