Senetas CypherNET CN4000 Series 1Gpbs Encryptors: Compact, versatile and high-performance encryptors for network data security without compromise.

Because both large and small organisations’ networks are vulnerable to damaging security breaches, Senetas developed the CN4000 series of certified high-assurance encryptors.

Despite their low cost and small form-factor, CN4000 Series encryptors have the same robust security credentials as the rack-mounted models.

About the CN4000 Series

The CN4000 series is the ideal low-cost, high-performance encryptor range for Small to Medium Enterprises (SME). They also provide a cost-effective “encrypt everywhere” solution for Large Enterprises.

Setting a new price/performance benchmark, the CN4000 Series is designed to meet more modest network requirements, but still delivers the same high-assurance encryption security that make Senetas encryptors stand out.

CN4000 encryptors deliver cutting edge protection of data, voice and video communications – without compromising network performance.

Key Senetas CN encryptor benefits such as zero network impact, near-zero latency, ease of implementation, 100% interoperability, and 1Gbps encryption are all a part of the CN4000 Series.

Integration with CipherTrust

Senetas CypherNET CN Series encryptors include integrated support for Thales CipherTrust, the industry’s leading centralised key management platform.

CipherTrust provides simple and secure encryption key management across the entire lifecycle; including key generation, storage, distribution and deletion.
