What Oesia Group does

Oesia Group (formerly DOI INGENIEROS, rebranded in 2016) is a Spanish multinational technology group founded in 1976, headquartered in Rivas-Vaciamadrid (Madrid), and operating across 42 countries on four continents. The group is structured around five specialized business lines: Oesía Networks (IT services, cybersecurity, and digital transformation), Tecnobit (defense electronics and optronics), Cipherbit (secure communications), UAV Navigation (autonomous flight control systems for unmanned aircraft), and Inster (communications and defense electronic systems). It is classified by NATO as a strategic supplier and holds CCN, ENS High-Level, and PECAL/AQAP 2110/2210 manufacturing certifications, supplying components into platforms such as the Eurofighter (sole supplier of optronics since 2005), A400M, F-18, and Leopard 2E.

The group's revenue model combines long-cycle defense platform integration contracts, multi-year cybersecurity service agreements, and bespoke systems integration projects for government ministries and security forces. Its technology stack spans hardware (thermal cameras, IRST systems, RF communications, autonomous flight controllers) and software (predictive maintenance, digital twin platforms, generative AI applications, secure communications), with proprietary intellectual property concentrated in autonomous UAV guidance and electro-optical systems. Customers are predominantly defense primes (Airbus, Lockheed Martin, Boeing, BAE, Leonardo, Saab, Rheinmetall), NATO, and Spanish and allied government ministries.

Oesia employs 501 to 1,000 staff and has been listed on the Forbes España Top 100 ranking. In 2026 the group took in Nazca Capital as a minority partner (25.79%, with the right to increase to 39%) to finance its 2026-2030 Strategic Plan and concurrently converted its legal structure to a Sociedad Anónima. Following four acquisitions executed between 2021 and 2024, the group has expanded from a domestic engineering services firm into an integrated defense electronics, secure communications, and unmanned systems supplier operating at mid-cap industrial scale, consistent with Spanish defense primes in the mid-hundreds of millions of euros in annual turnover.

Scale indicators10 records

Recent moves7 records

Expansion highlights6 records

Direct peers

• Indra: Spain's largest defense and IT systems integrator, providing radar, command-and-control, simulation, and digital transformation services. Indra is the closest Spanish peer given overlapping defense electronics, IT services, and a joint Epicom cryptographic acquisition with Oesía, serving largely the same Ministry of Defence and Tier-1 prime customer base.
• Teledyne FLIR: US-headquartered thermal imaging and infrared sensing specialist, now part of Teledyne. Directly comparable to Oesía's optronics and IRST franchises (cooled/uncooled infrared cameras, search-and-track systems) for land, naval, and aerial platforms.
• Sener Aeroespacial: Spanish engineering group with an aerospace and defense division supplying electromechanical systems, guidance, and space mechanisms. Closely comparable to Oesía as a fellow Spanish mid-tier defense engineering house competing for the same national sovereignty contracts and EU-funded programs.
• Ultra Electronics: UK-based specialist in defense electronics, mission-critical communications, and sonar — now operating under Cobham ownership. Comparable mid-tier position to Oesía in tactical data links, SATCOM, and naval sensors, with a similar business model of supplying subsystems into larger defense prime platforms.
• Hensoldt: German pure-play sensor house specializing in radar, electronic warfare, optronics, and avionics — directly comparable to Oesía's Tecnobit (optronics, IRST) and UAV Navigation (GNC) franchises. Hensoldt's listing on the Frankfurt Stock Exchange provides a useful valuation reference for Oesía's defense-electronics portfolio.

Emerging players

• Capgemini Engineering: Global IT services and engineering firm with a significant digital transformation, cybersecurity, and embedded systems practice. Comparable to Oesía Networks' civil-side digital transformation and managed services business for banking, public sector, and telecom clients, although Capgemini lacks Oesía's defense products.

Broad incumbents

• Saab: Swedish defense and security group with overlap across optronics (a customer of Oesía's optronics integration), tactical communications, UAVs (Skeldar), and naval systems. Operates as a broad incumbent in the same European defense sovereignty space where Oesía positions itself.
• Thales: Global French defense prime with a strategic technology alliance with Oesía. Overlaps with Oesía in SATCOM, tactical communications, optronics, and avionics, but operates at far greater scale across aerospace, space, and digital identity — making Thales both a partner and a potential in-housing threat to Oesía's subsystems positions.
• Leonardo: Italian defense prime covering helicopters, electronics, cyber, and space. Overlaps with Oesía across avionics, mission computers, secure communications, and simulation, and is a customer-supplier partner (Leonardo in Oesía's defense integration list). Comparable breadth of defense electronics portfolio but at substantially larger scale.

Regional players

• ITP Aero: Spanish aero-engine and components manufacturer (now part of Rolls-Royce). Adjacent Spanish aerospace peer serving overlapping Tier-1 prime customers (Airbus, Boeing, Eurofighter) and a likely collaboration partner on European engine and propulsion sovereignty initiatives.
