Cut the months between ready and approved.
An Authority to Operate (ATO) needs evidence that controls run on every service. Most teams gather that evidence by hand.
From first install to a signed ATO.
Dana Ortiz leads security for a defense agency's personnel records system. Her mission team cannot use it until it has an ATO. Here is what happens, step by step.
Controls running from day one.
Dana's team installs Greymatter once, on the cluster it already runs. No app is rewritten. Encryption, identity, and a request record run on every service. In the security plan, Dana cites FIPS 140-3 validated encryption (CMVP #5191) instead of building and testing her own. Post-quantum encryption is on by default.
Fix gaps before they become findings.
Dana prints the control report before the assessor arrives. It maps her controls to NIST SP 800-53 and lists one service without an access rule. Her team adds the rule that day. When the assessor asks who opened the system last Tuesday, Dana searches one record.
Ship fixes without reopening the ATO.
After approval, her team changes an access rule. Greymatter writes the change to a tamper-evident log with the name of the person who made it. Her team pins the release, so the running build still matches the approved one.
New sites, same approved build.
The agency adds an air-gapped site. It pulls the same pinned release from a registry the agency controls. The security setup matches the approved one, and Greymatter records evidence the same way.
AI agents the assessor can approve.
The team adds a records summarizer, an AI agent. Greymatter gives it a verified identity and access to case files only. When it reaches for payroll data, Greymatter denies the request and records it.
Less manual work, role by role.
An ATO pulls in program managers, security officers, engineers, and assessors. Today they all lose time to the same manual work. Here is what they get back.
