Hyperproof

Hyperproof is a compliance operations platform designed to take the manual grind out of staying compliant. You can manage all your frameworks—like SOC 2, ISO 27001, and HIPAA—in one central location rather than juggling endless spreadsheets. It automates the tedious process of evidence collection by syncing directly with your existing tech stack, ensuring your controls are always up to date and audit-ready.

You can also identify security gaps in real-time and collaborate with your team on remediation tasks through integrated workflows. Whether you are preparing for your first audit or managing a complex global compliance program, the platform provides the visibility you need to reduce risk and prove your security posture to customers and partners.

MailStore

MailStore helps you take full control of your company's email data by creating 1:1 copies of all emails in a central archive. You can secure large volumes of data permanently while meeting complex legal retention requirements and GDPR obligations. By offloading emails from your active server to the archive, you significantly reduce the workload on your IT infrastructure and eliminate the need for unreliable PST files.

You can empower your team with lightning-fast full-text searches for emails and attachments, accessible directly through Outlook or a web browser. Whether you use Microsoft 365, Google Workspace, or an on-premise Exchange server, the software integrates into your existing environment. It is specifically designed for small and medium-sized businesses looking for a reliable way to prevent data loss and simplify backup processes.
