Zevenbergen, January 14, 2026 — Attic Security and M365Permissions are partnering up to give organisations full visibility into access permissions within Microsoft 365 and Azure environments. Through this partnership, Attic Security can easily offer the M365Permissions tool to its clients, helping organisations get a clearer picture of who has access to what data, with support for interpreting and acting on the findings.
Many organisations do not know exactly who has access to sensitive data in their Microsoft cloud environment — whether it concerns users, systems, or external parties. This lack of visibility often stems from the complexity of cloud environments and insecure default settings, and poses a clear risk to data security and regulatory compliance.
M365Permissions provides a cloud solution for managing and auditing access within Microsoft 365 and Azure. Unlike traditional solutions that primarily focus on roles or policies, this tool shows exactly who has access to which files and systems — including permissions granted by users or systems. This gives a concrete answer to a key question from standards like ISO 27001: ‘Who is allowed to do what?’
The M365Permissions solution is deployed within the client’s own Microsoft cloud environment. This means organisations retain full control over their data and access permissions, with no shared platform involved. This makes the solution not only easy to deploy, but also secure and transparent.
"Organisations often think their Microsoft 365 environment is under control, while they don't have a complete picture of who has access to what data," says Rik van Duijn, hacker and co-founder of Attic Security. "With M365Permissions we can provide this insight in a practical and demonstrable way, and help clients actually take action on it."
Jos Lieben, Owner of M365Permissions: “Attic Security is not just a strong partner, but a truly like-minded organisation. Together, we are making access permission visibility more accessible for Dutch SMBs, while organisations retain full control over their own environment.”
