Sekoia.io

Sekoia.io provides a cloud-native SOC platform that combines XDR (detection and response across endpoints, network, and cloud) with an integrated cyber threat intelligence (CTI) feed, aimed at bringing SOC-grade detection to organizations and MSSPs that can’t staff a full in-house security operations center. The company has increasingly layered agentic AI into the platform to auto-triage and auto-resolve detected threats rather than routing everything to a human analyst.

The company traces back to a French security consultancy founded in 2008 that built its early reputation on CERT incident response, red team, and GRC/audit services, then pivoted toward product starting around 2015 out of frustration with the alert-correlation tools available to operational security teams at the time. Its SaaS XDR/CTI platform launched commercially in 2020. Headquartered in Paris, Sekoia.io raised €10 million in its first funding round in October 2020, followed by a €35 million Series A in May 2023 — at the time a record for a European cybersecurity Series A — and a €26 million Series B in April 2025, bringing total funding to roughly $78 million.

In its Series B announcement, the company reported that of about 4 million real threats detected across its platform in 2024, 25% were resolved fully automatically, an internal metric pointing to growing automation in its detection engine.

Sekoia.io competes in a crowded XDR/SIEM/MSSP-platform category against much larger incumbents such as CrowdStrike, Microsoft, and Palo Alto Networks, along with other European challengers. Its differentiation rests on natively integrating CTI into the detection platform from the outset and on a European/sovereign-cloud positioning that appeals to EU customers with data-residency requirements.
