Engagement Model

A predictable path from kickoff to authorization.

Most full-scope ATO engagements land in a twelve-week window. Shorter scopes typically run two to six weeks.
01
Week 1
Scope
Boundary definition, control selection, and system categorization so everyone agrees on what is in scope before a single control is examined.
02
Weeks 2-6
Assess
Control-by-control examination, interviews, artifact review, and technical testing against the applicable baseline.
03
Weeks 6-9
Document
SAR, POA&M, SSP updates, and the supplemental artifacts that give the AO everything needed to make a risk acceptance decision.
04
Weeks 9-12
Authorize
AO package delivery, response support, and the answers to the questions you did not know they would ask.
05
Ongoing
Sustain
Continuous monitoring, significant-change analysis, and the rhythm that keeps the authorization in good standing.
