Best Data Encryption Tools

Identity-Centric Security Protecting People, Devices, and Data in the AI Era

Together, we provide innovative platforms designed to reduce the complexity and risks of managing and protecting more applications, data, and identities than any other company can.

Netskope provides Netskope One Data Loss Prevention (DLP), a cloud-delivered solution integrated into its Security Service Edge (SSE) platform for zero trust data protection. It secures sensitive data across SaaS, IaaS, private apps, web, email, endpoints, and AI environments using unified classification, policy enforcement, and incident management. The patented lightweight endpoint agent enables context-aware inspection of local peripherals like USB drives with cloud-based ML classifiers, OCR, file fingerprinting, and exact data matching (EDM). Best for enterprises needing consistent DLP coverage in hybrid and cloud-native setups with high detection accuracy.

Protegrity provides encryption and key management for protecting sensitive data across databases, cloud services, and SaaS environments. In this category, its key-management controls focus on centralized lifecycle administration for master keys, repository keys, data store keys, signing keys, and data element keys, with support for external key custody through AWS KMS and Azure Key Vault. It is best suited for enterprises that need data-centric encryption controls tied to compliance and operational governance rather than a standalone hardware security module. The broader platform also includes adjacent data protection functions, but those are outside this profile.

Sophos defeats cyberattacks with an adaptive AI-native open platform and unmatched security expertise.

Tessian was a human-layer email security vendor that used machine learning to stop data loss, BEC, phishing, and accidental disclosure in email workflows. In an Encryption & Key Management profile, it is best understood as a control that reduces the need to send sensitive data unprotected, rather than a full cryptographic key management system. It fit enterprises already using Microsoft 365 and seeking policy-based email protection with DLP-style controls and user coaching. Tessian was later folded into Proofpoint, so this profile reflects a product-line capability set rather than an independent encryption platform.

Thales SafeNet is an enterprise MFA and access management platform combining authentication, SSO, and policy enforcement across on-premises, cloud, and virtual environments. The portfolio includes hardware tokens (eToken, smart cards, FIDO2 security keys), software authenticators, and the cloud-based SafeNet Trusted Access service. SafeNet serves large organizations requiring high-assurance authentication across distributed infrastructure, with particular strength in government and regulated sectors through FIPS 140-2 and Common Criteria certifications.

Vormetric, now part of Thales, is a data-at-rest encryption and key management product centered on the Data Security Manager (DSM) for centralized policy and key administration. It is used to protect files, databases, logs, and selected big-data workloads across physical, virtual, and cloud environments. In this category, it is best suited for enterprises that need centralized cryptographic control, auditability, and separation of duties for sensitive data protection. Adjacent capabilities historically included tokenization and access control, but the core buyer focus is encryption and key lifecycle management.
