Head-to-Head Comparison: Who Makes Project Management a Real No-Brainer

Security and Data Privacy

With data privacy in mind, Leantime.io falls over backward, facilitating entrepreneurial-minded teams and enterprises with a high-security grade. Leverage SSL data encryption, self-hosted and secure installation, Lightweight Directory Access Protocol (LDAP) and Single Sign-On (SSO) capabilities, user-based permission access, and data back-ups.

Moving beyond, the open-source project management system helps US-based healthtech-enabled startups and medical providers stay loose on complying with federal regulatory standards like Health Insurance Portability and Accountability Act. The platform is fully HIPAA-compliant, helping healthcare product teams seamlessly process their project-related operations and making electronic patient information management a cinch.

OpenProject keeps up with the security and privacy trends delivering  LDAP sync, single sign-on, 2-factor authentication, GDPR and German Federal Data Protection Act (BDSG) compliance, and AES-256 encryption as premium features.

On the contrary, Taiga is way less packed with data privacy and encryption protocols out-of-the-box, providing LDAP account database integration by default.

Leantime is built with non-project-manager business folks in mind streamlining the installation process as well. Once you decide to proceed with on-your-own hosting, all you need is to download the latest release package, set up an empty MySQL database, upload the directory to your server, fill in your DB credentials, and finally follow the easy instructions to getting the first user account up and running.

  • PHP 8.0 and up
  • Apache with mod_rewrite, Nginx, IIS (possible with adjustments)
