Built by Defenders,
For Defenders.
Graphion was founded by a team who spent decades on the other side — responding to breaches, chasing alerts, and watching attackers move faster than defenders could think. We built the platform we always needed but never had.
We exist to give defenders
the same advantage
attackers already have.
Attackers think in graphs. They think about relationships, choke points, lateral movement, and the fastest path to the crown jewels. They don\'t care about your org chart or your tool stack. They care about what\'s exposed, what\'s connected, and what can be abused.
Most security platforms answer questions about events. Graphion answers questions about paths. The moment you can see every viable attack route into and through your environment — continuously, in real time — you stop chasing alerts and start eliminating risk at the root.
Amsterdam HQ — Our platform processes over 3.2 billion threat signals daily across 140+ enterprise environments.
The Road to Graphion
The Breach That Started It All
Co-founders Marcus Velde and Dr. Anya Strauss were leading incident response for a major European financial institution. Despite having every top-tier security tool deployed, attackers had been living in their network for 214 days. The investigation revealed the same painful truth: tools don't fail. Context does. Graphion was incorporated three months later.

First €10M ARR & Series A
After two years building with a tight cohort of design partners — enterprise banks, telcos, and critical infrastructure operators — Graphion closed a €22M Series A led by Sequoia Capital Europe. The product had already mapped over 400 million attack paths across customer environments.

Active Response Intelligence
Graphion became the first attack path intelligence platform to close the loop from detection to automated containment — without requiring agent deployment. Active Response Intelligence launched with zero-touch containment, automated deception layers, and board-ready reporting in a single platform.

What CISOs Ask Us
Before They Buy
We\'ve had this conversation with hundreds of security leaders. Here\'s what matters.
No Agents. No Exposure.
Graphion operates agentlessly using read-only API connectors. We never execute code in your environment, never require elevated credentials, and never ship data outside your sovereign boundary. Your risk posture doesn't increase to reduce your risk posture.
EU Sovereign Cloud
All data is processed and stored within EU-based data centres. Fully compliant with GDPR, NIS2, and DORA. For regulated industries with strict data residency requirements, we offer private cloud deployment with zero-copy processing in your own AWS or Azure tenant.
30-Day Proof of Value
No six-month POC. No endless professional services engagement. Graphion delivers an authorised attacker's view of your environment — with mapped attack paths, prioritised findings, and a board-ready risk report — within 30 days. If you don't see value, you pay nothing.
Board-Ready Reporting
CISOs don't need another alert feed. They need a coherent narrative about business risk. Graphion's Compliance & Board Reporting module generates executive briefings mapped to NIST CSF, ISO 27001, CIS Controls, and your own KPIs — at the click of a button.
Integrates in Days, Not Months
Over 140 native integrations with SIEM, EDR, cloud platforms, identity providers, and CMDB systems. Average time from contract signing to first findings briefing is 9 days. No rip-and-replace. Graphion amplifies the tools you already paid for.
Dedicated SecOps Partner
Every enterprise customer receives a named Security Intelligence Advisor — a practitioner who has held a CISO or senior security engineering role. They join your weekly threat reviews, help interpret findings, and escalate zero-days directly to your team 24/7/365.
Certifications & Compliance
Heard from CISOs
"Graphion showed us our entire blast radius in 72 hours. We'd had a Tier-1 SIEM deployed for four years and never seen what they showed us on day one."
Group CISO
Top-5 European Bank
"The board report alone saved me four hours of prep per quarter. But it's the attack path model that changed how my team operates every single day."
VP Cybersecurity
FTSE 100 Energy Group
"We went from 14,000 open vulnerabilities in our queue to 23 validated, exploitable attack paths that actually mattered. That clarity is priceless."
