Atsign is a cryptographic identity and secure communications platform built around the atProtocol, with keys generated at the edge and encrypted data exchanged only between authorized Atsigns. In the Encryption & Key Management scope, its main value is non-custodial, peer-to-peer key handling: private keys stay on sender and receiver devices, and the infrastructure operator cannot decrypt customer data. It is best suited for IoT, distributed systems, and agentic AI teams that want end-to-end encrypted messaging without centralized key custody or exposed inbound ports. Atsign also offers adjacent secure remote access tooling, but the core security model is protocol-level encryption.

AWS Key Management Service (AWS KMS) is AWS’s managed encryption key service for creating, storing, and controlling cryptographic keys used to protect data in AWS workloads and applications. It is positioned for organizations that want key lifecycle control without running their own HSM fleet, and it uses FIPS 140-3 Level 3 validated HSMs under the service boundary. Buyers typically use it for envelope encryption, application signing, and server-side encryption across AWS services. It is best suited to teams standardizing key governance inside AWS rather than managing separate on-premises key systems.

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

Evervault is a developer-focused encryption and data de-identification platform used to protect sensitive fields while keeping applications able to process data without exposing plaintext. In the Encryption & Key Management category, it centers on application-level encryption, tokenization, and key handling built around its Evervault Encryption Engine (E3) running in an AWS Nitro Enclave. It is best suited for teams handling payments, cardholder data, and other regulated records that need encryption patterns embedded into application workflows rather than managed as a standalone vault. Adjacent functions such as secure enclaves and payment-specific tooling exist, but the core value here is encrypting data in transit and at rest with vendor-managed cryptographic operations.

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.
