Collective Defence

Collective Defence was formed in February 2026 through the combination of ITC Secure, a UK-based managed security services provider (MSSP) running 24/7 SOC operations since 1995, and IronNet, the network detection and ‘collective defense’ technology pioneer founded in 2014 by former NSA director Gen. Keith Alexander. The combined offering pairs ITC Secure’s managed detection and response (MDR) services with IronNet’s anonymized threat-sharing technology, which lets threat indicators observed in one customer’s environment inform defensive tuning across other participants in near-real time, plus Microsoft Security Copilot integration for AI-assisted SOC analysis.

IronNet’s own path was turbulent: it went public via SPAC in 2021, struggled financially as a standalone public company, and filed for Chapter 11 bankruptcy in October 2023 before its technology and remaining assets were carried forward. Combining that technology with ITC Secure’s established MSSP delivery organization and customer base is, in effect, a rescue-and-relaunch of the collective-defense concept under new commercial packaging, headquartered in Luxembourg with operations in the US, UK, and Singapore, led by CEO Arno Robbertse and Chairman Andre Pienaar.

The core idea — that anonymized cross-customer threat sharing can catch novel attacks faster than any single organization’s telemetry alone — remains a genuinely differentiated concept in a market dominated by single-tenant MDR and SIEM offerings, but the new entity has no independent operating track record yet, and IronNet’s prior bankruptcy is a real caution flag on execution risk that the ITC Secure combination has not yet had time to resolve.
