We design, build, and secure cloud software for federal agencies and contractors to FedRAMP and NIST 800-53: the controls, the documentation, and the evidence your authorizing official expects. For agencies, system integrators, and SaaS vendors selling into government.
An authority to operate (ATO) is won on evidence, not intentions. The gaps that slip a federal launch are predictable:
NIST 800-53 controls missing or undocumented, so the system cannot show how it actually meets the baseline.
No SSP, no control narratives, no evidence package. The assessment cannot even begin without it.
An ill-defined boundary turns the assessment into chaos and pulls far more of the system into scope than necessary.
FedRAMP requires ongoing ConMon. Without scanning, logging, and reporting in place, authorization lapses.
Findings with no plan of action and milestones, so risk cannot be managed or accepted by the AO.
The system cannot produce the evidence an assessor asks for, and the ATO slips by months or quarters.
Start with a fixed-fee readiness assessment. You get a straight answer on where the system stands against the NIST 800-53 / FedRAMP baseline, what it takes to close the gaps, and a fixed quote, before you commit to a larger build.
We are a US-based small business that builds software where security and compliance are non-negotiable, with the set-aside credentials contracting officers look for.
A free 30-minute call to understand your system, your agency, and your authorization timeline.
We assess the system against the NIST 800-53 / FedRAMP baseline and hand you a prioritized gap report and a fixed quote.
We implement controls, produce the SSP and POA&M, and support you through assessment and authorization.
Sthenos Technologies is an EDWOSB/WOSB-certified custom software development firm headquartered in Tysons, VA, with an office in Bethesda, MD (NAICS 541511). We build FedRAMP- and NIST 800-53-aligned software for federal agencies, system integrators, and SaaS vendors, implementing the controls, documentation, and continuous monitoring needed to support an authority to operate (ATO).
FedRAMP authorization is granted to a cloud service offering, not to a development firm. We build and document systems to the FedRAMP and NIST 800-53 baseline and support your path to an ATO, so the authorization is issued for your offering, with the evidence ready.
Yes. We implement the NIST 800-53 controls, produce the System Security Plan (SSP) and POA&M, and work with your 3PAO and authorizing official through assessment and authorization.
Yes. We stand systems up on FedRAMP-authorized cloud environments such as AWS GovCloud and Azure Government, configured to the baseline.
Usually, yes. We start with the readiness assessment, then remediate: control implementation, boundary definition, documentation, and continuous monitoring.
