[ CUSTOM DEVELOPMENT ]
Defense software. Fixed price. Your code.
You got quoted eighteen months. Your offshore team is creating a FOCI problem. There is another way: fixed-scope defense contractor software development with NIST 800-53 compliance from the first commit and full source code ownership at delivery.
The problem with defense software development.
Small and mid-size defense contractors need custom software. The domestic development shops quote eighteen months and a price that breaks the budget. The alternative is an offshore team, and the moment a cleared customer asks "What's the FOCI situation?", the conversation gets uncomfortable.
Then there is compliance. Most shops build the application first and bring in a consultant to retrofit NIST 800-53 controls after the fact. That is where most of the cost hides. It is also where nearly all of the schedule risk lives, because controls retrofitted onto finished software break things, extend timelines, and inflate budgets.
“We can't put that in the cloud”
Defense companies are stuck between overpaying, accepting FOCI risk, or not building what the mission needs. A cleared software development company that builds compliance-native code at a fixed price should exist. Vyper is that company.
[ PROCESS ]
How it works.
Requirements Call
We scope your project on a no-charge requirements call. No obligation. We define the deliverables, the control set, and the timeline before anyone signs anything.
Fixed-Price Proposal
You receive a fixed-price proposal with defined deliverables, a compliance control mapping plan, and a delivery timeline. No hourly billing. No T&M. No scope creep.
Build
NIST 800-53 custom software development starts with control alignment written into the code from the first commit. Automated test coverage is built alongside the application, not added afterward.
Delivery
You receive the full source code, the compliance control mapping, the procedural QA plan, and the automated test suite. You own the code. We transfer it. The engagement is complete.
No-charge. No obligation. We scope it, you decide.
[ DELIVERABLES ]
What you get at delivery.
Full Source Code
The code is yours. Full ownership transfers at delivery: no license, no lock-in, no dependency on us to keep operating. This is what separates Vyper from shops that retain IP rights.
Compliance Control Mapping
A written artifact documenting which NIST 800-53 controls the code implements and how. Most shops charge separately for this. We include it. This mapping supports CUI compliant application development and FedRAMP-aligned builds alike.
Procedural QA Map
A plan from the user's perspective so you can independently verify that what you bought does what we said it does. You should not have to trust us. You should be able to test it yourself.
Automated Test Suite
The test suite ships with the code. You can validate the application against its requirements without depending on us.
Documented QA Plan
A complete quality assurance plan covering the testing methodology, coverage metrics, and validation procedures used during the build.
[ CODE OWNERSHIP GUARANTEE ]
The Vyper guarantee.
You own the code. Every custom development engagement transfers full source code ownership to the client at delivery: no license, no lock-in, no dependency on us to keep operating.
We warrant delivered code against the documented control set for 30 days after delivery. Defects we introduced, we fix.
We do not warrant an authorization outcome, because ATO depends on your authorizing official, your environment, and your continuous monitoring program. Any vendor who promises you an ATO is selling you something they don't control.
Pricing.
Projects typically start at $30,000. Fixed price, scoped on a no-charge requirements call. No hourly billing. No T&M. The requirements call defines exactly what you are buying, what it costs, and when it ships, before you commit to anything. We build IL5 application development projects, CUI-compliant applications, and classified environment tools at the same fixed-price standard.
