The engineering work that gets a system authorized and keeps it there

Security documents describe controls. Our engineers implement them: hardened hosts, locked-down pipelines, closed findings and the evidence assessors ask for.

Where Deosi works in the Risk Management Framework The seven RMF steps from prepare to monitor. Deosi does the engineering in implement, supports assessment, remediates for authorization and runs continuous monitoring. Step 1 Prepare Roles, boundary, inventory Step 2 Categorize FIPS 199 impact level Step 3 Select NIST 800-53 baseline Step 4 Implement Controls, SSP, hardening Step 5 Assess Evidence, findings Step 6 Authorize POA&M, ATO package Step 7 Monitor Scans, patching, alerts
Steps 4 to 7, shaded, are where our engineers do the hands-on work. We support your authorizing official and assessor; we do not issue the ATO.

What we deliver

ATO and compliance engineering

NIST 800-53 control implementation, SSP contributions, assessment support, POA&M remediation and compliance evidence.

Infrastructure and cloud hardening

Linux, Windows, Active Directory, cloud and network controls, containers, databases, application servers and CI/CD.

Security operations

Vulnerability scanning and remediation, patching, monitoring and alerting, incident investigation and compliance reporting.

Identity and sensitive data

Single sign-on, identification and authentication, data encryption, biometric and PII data protection.

Secure integration

Security gateways, FIPS-validated messaging and REST and SOA service security, from our DHS integration work.

DevSecOps

Security scanning and policy built into build and deployment pipelines, so findings are caught before release rather than after assessment.
