Corero, a specialist in distributed denial of service (DDoS) protection, reported a notable increase in orders during the third quarter of 2025, achieving $7.4 million compared to $6.0 million in the same period last year. This growth was attributed to new customer acquisitions, enhancements in product offerings, and a major renewal and expansion order in October. This development indicates a robust beginning for the fourth quarter of 2025.
The Q3 2025 order intake included new contracts across the USA, UK, Europe, Brazil, and Singapore, highlighting Corero's expanding global reach. Notably, two more CORE customer wins occurred in this quarter, adding to the initial two secured in Q2 2025.
