Event summary
- Corero Network Security achieved 23% year-over-year ARR growth, reaching $23.9 million in full-year 2025.
- Growth was primarily driven by displacing existing DDoS and network security vendors, indicating a shift in market preference.
- The company expanded geographically across North America, EMEA, APAC, and Latin America.

The big picture
Corero's success highlights the increasing importance of automated, real-time DDoS protection as cyberattacks become more sophisticated and frequent. The company's ability to displace incumbents suggests a growing dissatisfaction with existing solutions, potentially signaling a broader shift in the network security market. The company's geographic expansion indicates a global demand for its services, but also exposes it to varying regulatory environments and economic conditions.
What we're watching
- Competitive Dynamics
- The pace at which Corero can continue to displace established vendors will be crucial for sustaining its growth trajectory, as incumbents likely respond with competitive offerings or pricing pressure.
- Partner Reliance
- Corero's reliance on strategic alliances (HPE, Juniper, Akamai, GTT) introduces a degree of dependency; changes in these partnerships could impact deployment speed and market reach.
- Subscription Adoption
- The shift towards subscription-based and DDoS PaaS models will determine the predictability of Corero’s revenue stream and its ability to attract larger enterprise clients.
