QuantaStor’s storage grid technology is a built-in federated management system which enables QuantaStor servers to be combined together to simplify management and automation via CLI and REST APIs. The layered architecture of QuantaStor provides solution engineers with unprecedented flexibility and application design options that maximizes workload performance and fault-tolerance for a wide range of storage workloads. QuantaStor includes end-to-end security coverage enabling multi-layer data protection “on the wire” and “at rest” for enterprise and cloud storage deployments.

Tresorit is a zero‑knowledge, end‑to‑end encrypted cloud collaboration platform built for organizations that handle sensitive data. It enables secure file storage, syncing, and sharing while ensuring that only data owners and authorized recipients can access content—Tresorit itself cannot. Files are encrypted on the user’s device before upload and remain protected throughout storage and sharing. The platform supports secure internal collaboration and external data exchange through encrypted file sharing, secure email links, digital signatures, and encrypted data rooms for client and partner collaboration. Tresorit provides granular access controls, auditability, and configurable data residency to help meet strict security and compliance requirements. Designed as a privacy‑first alternative to traditional cloud tools, Tresorit allows teams to collaborate productively without compromising control, confidentiality, or regulatory obligations.

Folder Lock by NewSoftwares is a security-focused application designed to protect sensitive files and data using advanced encryption technology on both Windows and Mac systems. It uses military-grade AES 256-bit encryption to secure folders, documents, and personal information from unauthorized access. The software allows users to create encrypted lockers for local storage as well as cloud platforms like Dropbox, Google Drive, and OneDrive. It also includes a secure notes feature where users can safely store passwords and confidential data. Folder Lock supports cross-platform synchronization, enabling access to encrypted files across multiple devices, including Windows and macOS. The application is built with a user-friendly interface that integrates seamlessly with both operating systems. Users can securely share encrypted files with others without exposing passwords.

Secure, store and tightly control access to tokens, passwords, certificates, encryption keys for protecting secrets and other sensitive data using a UI, CLI, or HTTP API. Secure applications and systems with machine identity and automate credential issuance, rotation, and more. Enable attestation of application and workload identity, using Vault as the trusted authority. Many organizations have credentials hard coded in source code, littered throughout configuration files and configuration management tools, and stored in plaintext in version control, wikis, and shared volumes. Safeguarding and ensuring that a credentials isn’t leaked, or in the likelihood it is, that the organization can quickly revoke access and remediate, is a complex problem to solve.

Akeyless delivers identity security for an era shaped by automation and AI. The cloud-native platform secures machines, AI agents, and human access across hybrid, multi-cloud, and on-prem environments. It provides a practical path to secretless, identity-based access through secrets management, certificate lifecycle management and PKI, PAM, and unified governance. Akeyless is built on a cryptography foundation that combines encryption, key management, and Distributed Fragments Cryptography to keep sensitive material under customer control and protected from post-quantum threats. With integrations for cloud IAM, Kubernetes, CI/CD, and MCP-based AI agent workflows, teams can adopt and scale AI agents securely without expanding risk. Akeyless Jarvis™ delivers identity intelligence to surface risky access and strengthen oversight.
