The Government Communications Security Bureau (GCSB) is New Zealand’s national authority for communications security (COMSEC). COMSEC is the technology and processes used to protect our most sensitive data through advanced, high-grade encryption. COMSEC is the primary means of maintaining the integrity of highly classified New Zealand communications.
High-grade encryption
Encryption is the process of scrambling or coding data so it can be read only by someone with the means to return it to its original state. Our Cryptographic Solutions & Development team provides high-grade encryption products and support to government agencies and selected commercial entities above the RESTRICTED classification level.
