Criterion 1
Authenticated scanning coverage
Confirm the provider runs authenticated scans across operating systems, databases, web applications and container images on the cadence your authorization requires.
Vulnerability management for federal programs
The providers below run vulnerability management and support FedRAMP authorization work. A federal cloud program inherits a scanning cadence, remediation deadlines tied to finding severity, and a monthly continuous monitoring package that has to arrive complete, so what a buyer is really purchasing here is operational discipline rather than scanner coverage.
Authorization sets deadlines by severity and those deadlines do not pause for a quiet quarter. Anything that slips needs a deviation request carrying justification an authorizing official will accept. Vendors who treat the engagement as a scanning contract miss where the effort actually sits: triage, evidence collection, deviation paperwork, and a package assembled on time every single month without anybody chasing it.
Each profile lists the provider's vulnerability management scope alongside the compliance programs it supports. Ask which parts of the monthly continuous monitoring package the provider assembles and which parts stay with your own team.

Criterion 1
Confirm the provider runs authenticated scans across operating systems, databases, web applications and container images on the cadence your authorization requires.
Criterion 2
Ask how remediation deadlines are tracked per finding, who is alerted as one approaches, and what the reporting looks like a week before a deadline lands.
Criterion 3
Establish whether the provider drafts operational requirement and false positive deviation requests, and who owns the technical justification an official will read.
Criterion 4
Determine which continuous monitoring artifacts the provider produces, and whether the package arrives assembled or as raw inputs your team still has to compile.
Criterion 5
Clarify in writing which controls you inherit from the underlying platform, which the provider operates inside your boundary, and which remain entirely yours.
Healthcare, Financial Services, Retail & E-Commerce, Manufacturing, Hospitality
Deadlines attach to finding severity, with the highest severity carrying the shortest window and lower severities progressively longer ones. The exact windows live in program documentation and change over time, so confirm them against the authorization your program actually holds.
No. Authorization attaches to a service offering and its own defined boundary. A provider can support your package, operate controls inside your boundary, and let you inherit from an authorized platform, but the authorization itself stays with the offering.
Usually scan results across every required layer, an updated plan of action and milestones, any open deviation requests, and an inventory reconciliation. Confirm the exact contents against what your authorizing official expects to receive.
It narrows it rather than removing it. Controls inherited from an authorized platform still need documenting, and everything you deploy above that platform remains yours to scan, triage and evidence on the same schedule.
