“Software-defined warfare is not a future construct—it’s the reality we find ourselves operating in today.”
— DoD Memorandum, March 2025
In a major policy shift with wide-reaching implications, the Department of Defense has issued a stark directive: outdated acquisition models are putting national security at risk. The memo, titled “Directing Modern Software Acquisition to Maximize Lethality”, lays out an urgent roadmap to modernize how defense software is built, delivered, and secured.
A Blueprint for Defense Agility
As detailed in the DoD’s official statement from March 10, 2025, this is an attempt to move beyond bureaucratic housekeeping, a drive to implement reforms designed to restore U.S. digital dominance. The government warns: “Without a modern approach to software acquisition, the Defense Department risks falling behind adversaries.”
Here’s what’s changing, and why it matters:
- The Software Acquisition Pathway (SWP) is now the mandatory standard for all software elements across DoD programs.
- Commercial Solutions Openings (CSOs) and Other Transaction Authority contracts (OTAs) are required to accelerate contracting and open access to nontraditional innovators.
- The DoD is moving away from hardware-centric, waterfall-style timelines, instead targeting minimum viable products in under a year.
This strategy isn’t theoretical. Programs like the Replicator software project, have proven it works. The expedited 110-day cycle was facilitated by the Defense Innovation Unit (DIU) through the utilization of Commercial Solutions Openings (CSOs) and Other Transaction (OT) authorities. These mechanisms are designed to streamline the procurement process, particularly engaging non-traditional defense contractors, thereby fostering innovation and reducing bureaucratic delays.
Why This Will Transform Defense Capability
The stakes couldn’t be higher. Cybersecurity, autonomous systems, real-time threat response, modern warfare depends on software. And every delay in its deployment is a vulnerability. This initiative:
- Reduces time-to-field for mission-critical digital tools
- Encourages rapid prototyping and scalable innovation
- Fosters partnerships with agile vendors who can outpace threats
- Bakes cybersecurity into the acquisition pipeline, ensuring secure-by-design systems from day one
It’s not just about speed; it’s about shifting from reactive defense to proactive dominance. Now, software companies, especially small businesses, can compete based on the strength of their technology, not their ability to navigate a rigid, outdated procurement system.
This shift directly aligns modern software development practices with government needs, emphasizing rapid prototyping, iterative delivery, and a direct pipeline from innovative companies to defense programs of record. Instead of spending years writing exhaustive requirements, the Pentagon can now test, validate, and deploy commercial-grade solutions quickly, putting emerging tech into the hands of warfighters faster than adversaries can adapt. For software companies, this means faster awards, lower barriers to entry, and a real chance to bring cutting-edge solutions into national security missions without being buried under layers of contracting bureaucracy.
“Software companies make software. We’re going to buy software from software companies.”

Why GrammaTech Is Weighing In
At GrammaTech, we’ve been delivering advanced software and cybersecurity solutions to defense agencies for decades. We know firsthand the challenges and constraints of the old system:
- Writing proposals for years-long procurements that are obsolete by the time they’re awarded.
- Waiting on approval cycles that grind to a halt, even when innovation is urgently needed.
- Watching smaller, more innovative teams get sidelined by legacy processes favoring volume over velocity.
We’re not a massive defense contractor, we’re a small, agile, innovative software company, and we’ve been building what the DoD is now asking for:
- Autonomous cybersecurity tools like Proteus that deliver vulnerability discovery and remediation without human intervention
- Software that evolves with threats, not six months after
- Rapid deployment and continuous enhancement models built for secure, high-stakes environments
This policy shift is a clear signal: the DoD wants what companies like GrammaTech have always delivered, faster innovation, smarter tools, and real-time adaptability.
A Model for Agile, Autonomous Cyber Defense
Take Proteus, our advanced vulnerability discovery and remediation platform:
- Requires no source code access
- Uses symbolic execution, fuzzing, exploitability analysis, binary rewriting, and more
- Automatically detects and patches vulnerabilities, reducing time, effort, and error
- Proven in the DARPA Cyber Grand Challenge, Magma benchmarks, and real-world DoD deployments
- Built for classified environments with on-prem and SaaS models
- Supported by a planned open-source release to foster broader adoption
Proteus isn’t a prototype; it’s an operational tool that delivers security at the speed of conflict. And it’s exactly the kind of capability the new acquisition model is designed to deploy, scale, and evolve rapidly.
A Call to Support Small, Agile Software Companies
The new acquisition strategy doesn’t just clear a path for faster development, it creates space for companies like GrammaTech to bring their best work forward without being stifled by legacy acquisition cycles. We hope the department isn’t just making this a short-term shift. We hope that it’s laying the foundation for lasting reform. For software innovators ready to deliver security, agility, and performance, this memo could mark the start of an unprecedented era of opportunity.
In a contested, constantly evolving cyberspace, it’s the nimble, threat-aware, forward-leaning teams that will provide the decisive edge.
A New Era in Defense Software Is Starting
Defense capabilities in the 21st century depend on software that is agile, autonomous, and always advancing. The systems that protect lives and ensure national security must evolve at machine speed, not government speed.
GrammaTech is ready.
We’ve always been ready.
And now, the system is finally catching up.
