Security, Sovereignty & Geopolitics
Updated October 5, 2026
Cybersecurity, data sovereignty, and geopolitics reshaping satellite infrastructure.
The bottom line
Satellite networks are treated as critical national infrastructure, so who owns the spacecraft has become a procurement question rather than a technical one.
What is happening
The 2022 Viasat hack showed satellite systems are real military targets, and cybersecurity moved from afterthought to design requirement — encryption, zero-trust architecture and anti-jamming are now table stakes. Data sovereignty, meaning who controls traffic crossing foreign-owned satellites, increasingly decides procurement.
A second clock is running: 'harvest now, decrypt later'. State actors are documented intercepting and storing encrypted satellite traffic today, intending to decrypt it once quantum computers mature, which is driving post-quantum cryptography into both ground and space segments.

Open challenges
- Legacy satellites cannot be retrofitted with modern encryption
- Ground segment remains the most vulnerable attack surface
- Fragmented regulatory landscape increases compliance costs for global operators
- Spectrum allocation increasingly influenced by geopolitical alliances
- Data sovereignty requirements conflict with global satellite coverage models
- Risk of market balkanization reducing economies of scale
- Jamming and spoofing threats require hardware-level countermeasures
- Quantum computing threatens retroactive decryption of intercepted satellite data ("Harvest Now, Decrypt Later")
