Prepare for a CMMC Level 1 self-assessment by defining scope, checking your identity and endpoint baseline, reviewing vendor access and backups, and collecting simple evidence before anyone starts answering questions.
How to Prepare for a CMMC Level 1 Self-Assessment
A self-assessment gets easier when the team does the operational homework first. Most bad answers come from rushed assumptions, not from a lack of expensive tools.
If you want a faster path, compare your internal plan to CMMC Level 1 Readiness Review before you finalize anything.
This article is for practical readiness guidance only. It is not legal advice, and Sun Life Tech does not guarantee certification, affirmation, or contract outcomes.
We can quickly review your setup and show you what’s working and what needs improvement.
Use the IT Cost Savings Calculator to estimate annual waste from recurring support drag, outages, emergency work, and security cleanup before you decide what to prioritize.
Step 1: Define the actual scope
Identify which users, devices, shared folders, cloud services, and vendors touch FCI. If the answer is fuzzy, stop there and tighten scope first.
Step 2: Review the baseline controls
- MFA and password requirements
- Endpoint protection and patch compliance
- Firewall ownership and admin access
- Backups and restore testing
- Offboarding and access approval process
Step 3: Collect evidence before questions start
Gather the proof while the control owners are available: screenshots, reports, tickets, and policy documents. If the process feels weak, read the risk behind a weak CMMC Level 1 affirmation and then move into CMMC Level 1 Readiness Review.
