Ekinops taps former TrustBuilder, Corero exec Lionel Chmilewsky as its new CEO

He will work to position the company in data center interconnection (DCI) for optical transport and Secure Access Service Edge (SASE) opportunities.

Ekinops has named Lionel Chmilewsky, a veteran of cloud and broadband, as its new CEO, to return the company to profitable growth.

He takes over as CEO from interim CEO Philippe Moulin, who is Ekinops’ COO.

Moulin became interim CEO after long-term CEO Didier Brédy stepped down following the company's third-quarter revenue decline. In the third quarter of 2025, Ekinops reported revenue of $26 million, down 27% compared to the third quarter of 2024.

Chmilewsky joins Ekinops from TrustBuilder, a European SaaS cybersecurity company specializing in multi-factor authentication and identity and access management.

His ability to drive revenue growth will be a key skill for Ekinops’ CEO role.

Before TrustBuilder, Chmilewsky served as CEO of Corero Network Security, an anti-DDoS cybersecurity provider. During his tenure at Corero, Chmilewsky doubled revenue and Annual Recurring Revenue (ARR), delivered sustained profitability and accelerated growth in the US market. Earlier, Chmilewsky also served as CEO of Cambridge Broadband Networks and Comverse IP Communications. He also serves as Chairman of Hive Streaming.

"I look forward to putting my expertise to work alongside Ekinops' teams and contributing to the Group's future success in high-growth markets,” said Chmilewsky.
