Built for the attorney who should have had this ten years ago.
Your clients are discussing their cases in free ChatGPT right now. Those sessions are discoverable. Marcella is the only platform that closes that door.
Marcella is an orchestration layer that runs on top of your Microsoft 365 tenant. Your client data never leaves your Microsoft account. The AI never trains on your queries. Attorney-client privilege is protected architecturally, not by policy
"Wow."
In United States v. Heppner (S.D.N.Y., Feb. 2026), a criminal defendant used the free public version of ChatGPT to analyze his own legal defense. The FBI seized the devices. Judge Rakoff ruled the AI sessions fully discoverable. The public platform had no confidentiality protection. Privilege never attached.
The attorney did not use ChatGPT. The client did. On their own. Without telling anyone. That is the exposure that cannot be controlled by policy, email, or instruction alone. Until now.
The only way to close this door is to give the client a privileged channel, get a signed acknowledgment that they will use it, and document that the firm warned them. Marcella does all three — inside your Microsoft tenant, before the first session begins.
How Marcella closes the door →Government contracts now require CMMC certification. Companies lose bids and face contract termination over incomplete evidence packages. Marcella maps every policy and procedure to its required control at ingest. The package assembles itself. The assessment becomes a formality.
Benchmark audits, cost reduction, and managed services. Organizations we work with routinely see 20–50% OPEX reduction across their technology stack
"You should have access to every legal research tool a partner at a large firm has."
Not because you can afford a $1,500/month Westlaw subscription. Because the law should not be a luxury good.
Now you do.
Marcella is live for law firms, compliance teams, and government contractors. Provision takes minutes. Your data stays in your Microsoft tenant from day one.
