aPerry is a German IT security software vendor focused on cloud data protection through encryption and tokenization. Its core offering, the aPerry Gateway, is positioned as a zero-trust, “zero-knowledge” transparent encryption gateway/proxy that protects sensitive data (e.g., PII) across cloud applications, databases, and file services while preserving key application functions such as search via gateway-side logic and indexing. The company emphasizes customer-controlled cryptographic keys (including optional HSM integration) and selective encryption to support regulatory and privacy requirements such as GDPR and PCI DSS-oriented tokenization use cases.
