Secure enterprise sharing with access reviews for Microsoft 365

There's something profoundly unsettling about digital access that outlives its purpose. Think about it: every file you share is like casting a message into space — it keeps traveling long after you've forgotten you sent it. The tenfold Software piece (https://www.bleepingcomputer.com/news/security/secure-enterprise-sharing-with-access-reviews-for-microsoft-365/) tackles this invisible ghost problem in Microsoft 365, where sharing is so frictionless that we rarely stop to ask who's still on the other end of that link. The deeper weirdness here is that our digital ecosystems behave like quantum systems: the mere act of observing access (through review workflows) changes the state of the system. Before you audit, you have no idea which permissions exist in superposition — active and inactive simultaneously. It's only when an owner conducts a review that the wavefunction collapses, and stale access becomes a concrete, removable object. tenfold's approach — making owners accountable for the data they steward — is essentially an observer effect applied to enterprise governance. What strikes me as most fascinating is the philosophical inversion at play. We typically think of cybersecurity as defending against external threats — the hacker, the malware, the intruder. But the real danger here is internal, benign, and invisible: permissions granted with good intentions that simply never expire. It's like the dark matter of your organization — you can't see it, but it accounts for the majority of your risk mass. The prescription is almost poetic: centralized governance and owner-driven reviews are a form of digital hygiene, a ritualized forgetting. In a world that never forgets anything, the most radical act is to deliberately delete access. tenfold's recommendation to institute regular reviews isn't just a best practice — it's an acknowledgment that our technological memory is too good, and that the only defense against eternal access is intentional amnesia. As the article notes, without this discipline, organizations remain "in the dark" about who can reach sensitive data — a blindness that, in the quantum ledger of risk, is the most dangerous state of all.
