Software Development RFP Example for On-Prem Defense Tech Projects

I see this problem often. A defense contractor asked me for help. They needed an AI system for classified data. They wrote an RFP. They got 50 proposals. Only 2 were for on-prem. The rest were cloud-only. They wasted 200 hours reading bad proposals. That's a lot of time and money. The problem? Their RFP didn't say 'on-prem only' clearly. Vendors thought 'secure' meant cloud with extra locks. But defense tech needs air-gapped systems. No internet connection. No data leaving the building. Your RFP must say this from the start. Otherwise, you get the wrong vendors. And you risk a breach. One proposal used a public AI API. That isn't allowed for classified data. Another vendor said they could do on-prem but their plan used cloud for backup. That isn't secure. We had to reject all of them. Then we rewrote the RFP. We added a line: 'All data must stay on our servers. No cloud services allowed.' After that, we got better proposals. But we still had to check every detail. This is why your RFP must be very specific. Don't assume vendors understand 'secure.' Write exactly what you need. For example: 'The system must run in a VPC that has no internet access. All encryption must use FIPS 140-2. All access must use multi-factor authentication.' This saves you time and keeps your project safe.

Here's what I learned from many projects. The biggest mistake CISOs make isn't being clear about security. They write 'secure' but don't say what that means. For example, they don't ask for PostgreSQL hardening. PostgreSQL is a database. Hardening means making it safe from attacks. You need to say: 'Use CIS Level 2 benchmarks for PostgreSQL. Encrypt data at rest with AES-256. Use FIPS 140-2 modules. Set up role-based access control. Log all access and send logs to our SIEM.' If you don't say this, vendors will use default settings. Default settings aren't safe. I saw a project where the vendor used default PostgreSQL settings. The database was open to the internet. That's a huge risk. Another mistake isn't asking about Next.js deployment. Next.js is a web framework. You need to say: 'Deploy in a hardened Kubernetes cluster. Use a Web Application Firewall. Use mutual TLS for all APIs. Run containers as non-root users.' Without these details, vendors will use easy cloud setups. This costs you money. I estimate that vague RFPs cost companies over $200,000 in wasted time and fixes. For example, one client spent $50,000 to redo a database setup because the RFP didn't ask for encryption. They had to move all data and change the architecture. That's money you can save by writing a clear RFP.

Generic RFPs attract vendors who sell cloud hype. They say 'AI-powered' but mean 'cloud-only.' I've seen this many times. A vendor promises an AI assistant. But their plan uses a public LLM like ChatGPT. That means your data goes to their servers. That isn't allowed for defense tech. You need on-prem AI. That means the AI runs on your own computers. No data leaves your building. To get this, your RFP must ask for specific things. For example: 'Show us your plan for on-prem model training. Show us how you'll keep data inside our network. Show us that you've experience with air-gapped systems.' If a vendor can't answer these, they're not right for you. I worked with a team that got 30 proposals for an AI project. Only 3 vendors had real on-prem experience. The rest were cloud vendors. The team wasted 3 weeks reading bad proposals. Then they rewrote the RFP. They added a question: 'Describe your last on-prem AI project. What were the security rules?' This filtered out most vendors. The final 3 vendors gave good answers. The project was a success. So don't be afraid to ask hard questions. Your RFP is your first filter. Use it to remove vendors who don't understand defense tech security.

Many CISOs assume vendors know what 'secure' means. But in defense tech, 'secure' has a special meaning. It means data sovereignty: your data stays in your country. It means supply chain vetting: you check every part of the software. It means post-deployment hardening: you keep updating security after the system is live. Your RFP must ask about all these. For example, ask: 'Where will you store our data? Which laws apply? Can you show us your software bill of materials? Do you check your developers for security? How will you patch the system after we go live?' I saw a project where the vendor used a third-party library with a known security hole. The RFP didn't ask for a software bill of materials. So the team didn't know about the hole until after the system was running. They had to stop everything and fix it. That cost $100,000 and 2 months of delay. To avoid this, your RFP must be very detailed. For example, for PostgreSQL hardening, say: 'Use CIS Level 2. Encrypt data at rest. Log all queries. Use role-based access control.' For Next.js, say: 'Deploy in a VPC with no internet. Use a WAF. Use mutual TLS. Run as non-root.' Don't leave anything to chance. Write every requirement clearly. This is the only way to get a truly secure system.

Here's what works. I helped a defense contractor write a new RFP. We added very specific security requirements. For PostgreSQL, we wrote: 'Use CIS Level 2 benchmarks. Encrypt data at rest with AES-256 using FIPS 140-2. Use role-based access control. Log all queries and send logs to our SIEM.' For Next.js, we wrote: 'Deploy in a VPC with no internet access. Use a Web Application Firewall. Use mutual TLS for all APIs. Run containers as non-root users.' For AI, we wrote: 'All AI models must run on our servers. No data can leave our network. Show us your plan for on-prem training and inference.' We also asked for proof of experience: 'Show us three projects where you did on-prem deployment for government or defense. Show us your security clearances. Show us your CMMC 2.0 certification.' The result? The number of proposals dropped from 50 to 12. But all 12 were from vendors who could really do the work. The team saved 3 weeks of evaluation time. They also saved about $30,000 in engineering time. More importantly, they got a secure system that passed all audits. The key is to be very clear. Don't use words like 'secure' without details. Write exactly what you need. This attracts the right experts and keeps your project safe.

Every bad RFP cycle costs you more than time. It risks your contracts. I've seen a team lose a $50 million contract because their system had a security hole. The hole came from a cloud service they didn't know about. The vendor had used a public API for AI. The data leaked. The government found out. The contract was terminated. The company also got a fine of $10 million. They couldn't bid on new contracts for 5 years. That's a disaster. This can happen to you if your RFP isn't clear. In 2026, cyber threats are worse. Hackers target defense tech. You must protect your data from the start. The cost of inaction is huge. It's not just money. It's your reputation. It's your career. I always tell teams: 'Your RFP is your first line of defense. Make it strong.' Don't wait until after a breach. Fix your RFP now. It's the best investment you can make.

How do you know if your RFP process is broken? Look for these signs. First, you get many proposals that are cloud-only. Even though you asked for on-prem. Second, your team spends weeks checking security claims. Third, you find serious problems after you sign the contract. For example, hardcoded passwords in the code. Or data that isn't encrypted. Or a vendor who uses a public cloud for backup. If any of these happen, your RFP isn't working. I worked with a team that had all three problems. They were losing money and time. They were also at risk of a breach. We rewrote their RFP. We added very specific security rules. After that, the bad proposals stopped. The team saved time and money. They also felt safer. So look at your own process. Are you getting the right vendors? Or are you wasting time? If it's the second, you need to change your RFP.

Here's how I fixed this for a major defense contractor. Their AI project was stuck. Every vendor offered cloud solutions. I helped them rewrite their RFP. We added specific requirements for PostgreSQL hardening and Next.js deployment. We also asked for proof of CMMC 2.0 compliance. The result? The number of proposals dropped from 50 to 12. But all 12 were from vendors who could do on-prem. The team saved 3 weeks of evaluation time. They also saved $30,000 in engineering time. The project went live on time and passed all security audits. The team was happy. The client was happy. This shows that a clear RFP works. It doesn't just prevent problems. It gets you the right solution faster. If you want the same result, start by writing a very specific RFP. List every security rule. Ask for proof of experience. Don't accept vague answers. This is the only way to build secure defense tech systems.
