Tehtris, a Paris-based startup that offers an XDR service that monitors IP addresses in 60 countries to stop cyber attacks, raises €20M Series A
Tehtris, a Paris, France-based provider of cybersecurity solutions, raised €20M in Series A funding.
Context & Ripple Effects
Tehtris' €20M Series A lands in a Paris cybersecurity cluster that was already drawing institutional money: a year earlier, EfficientIP raised an $11M Series B from Jolt Capital to fight DDoS attacks, and TrapX had shown US investors would fund real-time attack-thwarting tools at Series C scale.
The round also predates the wave that followed it — Sekoia's $35M Series A in 2023 for real-time detection, Filigran's $58M Series C in 2025 for open-source threat intelligence used by the EU and FBI, and Riot's $30M Series B for security training — making Tehtris an early data point in Paris becoming a repeat source of funded cyber-defense startups.
First-order effects
- Tehtris gets capital to scale its XDR service, which monitors IP addresses across 60 countries, giving it runway to expand coverage and sales while rivals like EfficientIP remain focused on DDoS-specific defense.
Second-order effects
- Later entrants such as Sekoia and Filigran raise larger rounds ($35M-$58M) in adjacent detection and threat-intelligence niches, forcing buyers to choose between consolidated XDR platforms like Tehtris and specialized point solutions.
Third-order effects
- If the pattern holds, Paris consolidates into a self-sustaining cyber-defense ecosystem where each funded startup — detection, intelligence, training, network defense — deepens the local talent and investor base that funds the next one.
The trend: Cyber-defense venture funding is clustering in Paris, with successive rounds from EfficientIP through Tehtris, Sekoia, Filigran, and Riot building a full-stack security ecosystem.
