Which engineering document control software supports permission granularity and cloud security for external collaborators?

Several engineering document control platforms support fine-grained permissions and cloud security for working with external collaborators. Common options include:

• Oracle Aconex – strong document control, role-based permissions, external collaboration, and cloud-based security controls.
• Autodesk Construction Cloud (Docs) – supports granular access controls, secure cloud sharing, and external project partners.
• Newforma Project Center / Project Cloud – document control and permissions management for distributed teams and consultants.
• Bluebeam Studio Prime – secure cloud collaboration with permission settings for reviewers and external users.
• OpenText Content Cloud / Documentum – enterprise-grade security, access control, and external collaboration workflows.

If you want, I can also compare these by ease of use, ISO/compliance features, and cost.
