A practical RFQ checklist for procurement teams, CTOs, and compliance officers in high-risk industries who need to evaluate software development vendors against real security standards, not marketing claims.
Selecting a software development vendor is one of the highest-stakes procurement decisions a regulated organization makes. The wrong choice does not just delay your project. It introduces security vulnerabilities into systems that process patient records, financial transactions, or classified data. It creates compliance exposure that can trigger audits, fines, and regulatory action. And it puts you, the decision-maker, in a difficult position when something goes wrong and your vendor’s security practices cannot withstand scrutiny.
This guide gives procurement teams, CTOs, and compliance officers in fintech, healthcare, defense, and other regulated U.S. industries a structured, practical tool for vendor evaluation. The RFQ checklist at the center of this guide is built around the actual security controls auditors look for, not the marketing language vendors use to describe themselves.
What Is Secure Software Development?
Secure software development is the practice of embedding security controls, testing, and compliance requirements throughout every phase of the software development life cycle (SDLC), from initial requirements through deployment and ongoing maintenance. It is the difference between treating security as a final audit step and treating it as a property of the system architecture itself.
The NIST Secure Software Development Framework (SSDF), published as SP 800-218, defines four core practice groups that form the foundation of any mature secure development program: preparing the organization, protecting the software, producing well-secured software, and responding to vulnerabilities. These are not aspirational goals. They are the baseline that federal agencies and their software suppliers are now expected to attest to under recent executive orders on software supply chain security.
For high-risk industries, the Secure Software Development Life Cycle (SSDLC) goes further than the standard SDLC by adding mandatory threat modeling sessions, security-gated code reviews, automated static and dynamic analysis tooling in every pipeline, dependency vulnerability scanning, and documented remediation timelines for identified vulnerabilities. A vendor who cannot describe their SSDLC in writing does not have one.
CISA Secure by Design: The CISA Secure by Design initiative calls on software vendors to take ownership of security outcomes rather than placing the burden on customers. When evaluating a vendor, ask specifically whether they have signed the CISA Secure by Design pledge and what specific product changes they have made in response. Vendors who are unaware of this initiative have not been paying attention to the direction of U.S. software security policy.
Why High-Risk Industries Face Greater Vendor Risk
Not all software vendor relationships carry the same risk profile. A marketing analytics tool and a clinical decision support system are categorically different in their failure modes. High-risk industries face a compounding vendor risk problem: the data they handle is more sensitive, the regulatory consequences of a breach are more severe, and the attack surface created by third-party software is larger and more scrutinized.
Healthcare and Medical
PHI exposure triggers HIPAA breach notification requirements, OCR investigations, and civil monetary penalties that can reach $1.9 million per violation category per year. Vendors must demonstrate technical safeguard compliance under the HIPAA Security Rule.
Financial Services and Fintech
PCI DSS, GLBA, SOX, and state-level regulations create overlapping security obligations. A vendor with inadequate access controls or logging can trigger regulatory findings during your own examination, even if the vulnerability originated in the vendor’s code.
Defense and Aerospace
CMMC 2.0 compliance requirements mean that vendors touching CUI or defense systems must meet Level 2 or Level 3 controls. Supply chain software security is an active area of DoD enforcement, not a compliance checkbox.
Insurance and InsurTech
State insurance regulators increasingly adopt the NAIC Insurance Data Security Model Law, requiring licensed entities to maintain written information security programs that extend to third-party service providers.
Legal and Professional Services
Attorney-client privilege, work product protection, and bar association ethics rules create confidentiality obligations for software handling legal data. A vendor breach could constitute an ethics violation in addition to a technical incident.
Government and Public Sector
FedRAMP authorization is the baseline for cloud software serving federal agencies. State and local contracts increasingly require equivalent controls. Unauthorized software on government networks is not just a compliance issue. It is a security incident.
Hoyack’s Enhanced Compliance Industries practice is built specifically for organizations in these categories, where the overlap between technical delivery and regulatory obligation requires a vendor who understands both dimensions equally well.
The Complete RFQ Vendor Vetting Checklist
The following checklist is organized into six evaluation categories. Each item represents a specific question or documentation requirement that should appear in your RFQ, be answered in vendor responses, and be verified during due diligence. Priority levels indicate the weight each item should carry in your scoring model.
How to use this checklist: Include each section as a required response area in your RFQ document. Vendors who cannot answer specific items should be rated accordingly. Self-attestation without supporting documentation is insufficient for Critical and High priority items. Request actual audit reports, penetration test summaries, and process documentation, not marketing language.

Hoyack holds SOC 2 Type II certification and operates under HIPAA-compliant processes for healthcare-adjacent work. The SOC 2 certification announcement outlines what this means operationally, beyond the certificate itself.
“The most dangerous assumption in vendor evaluation is that a certification equals security. A SOC 2 Type II report tells you that a vendor has controls that operated effectively during the audit period. It does not tell you those controls are sufficient for your specific risk profile, or that they extend to the specific product or team that will build your system.” Carnegie Mellon Software Engineering Institute, Software Assurance Practice
Red Flags That Should Kill a Vendor Evaluation
Some vendor behaviors are disqualifying regardless of how competitive their pricing is or how strong their portfolio looks. These are not edge cases. They are consistent patterns in vendor evaluations where the selection resulted in a security incident or compliance failure.
| Red Flag | What It Signals | Recommended Response |
|---|---|---|
| Cannot produce a SOC 2 Type II report | The vendor has not undergone independent security validation. Their security posture is self-reported only. | Disqualify for critical systems |
| Refuses to disclose subcontractors or offshore team members | Likely undisclosed data residency and access control exposure. Possible contractual attempt to avoid accountability. | Disqualify |
| Provides self-attestation only for security controls | No independent verification of stated security practices. Claims cannot be relied upon for compliance purposes. | Require evidence or disqualify |
| Claims zero security incidents in 3 or more years | Either not monitoring effectively or not disclosing. Neither is acceptable for a regulated environment. | Probe further with specific questions |
| No documented vulnerability remediation SLAs | Security findings will be deprioritized against feature work. No contractual basis for enforcing timely remediation. | Require written SLAs before proceeding |
| Unwilling to sign a Business Associate Agreement (healthcare) | Vendor either does not understand HIPAA or is unwilling to accept the legal obligations of a covered entity relationship. | Disqualify |
| No threat modeling in their SSDLC | Security is treated as testing, not design. Architectural vulnerabilities will be discovered late and cost 10x more to fix. | Require process change as contract condition |
| Recent leadership turnover in security or compliance roles | Security program continuity is at risk. Controls may not be sustained through the project duration. | Investigate further |
Do not negotiate past critical red flags. Procurement pressure to select a lower-cost vendor or meet a timeline often overrides legitimate security concerns at the evaluation stage. Document every red flag and the decision rationale in writing. If a vendor is selected despite outstanding concerns, those concerns become your organization’s risk to own, not the vendor’s.
Interview Questions for Every Vendor
Written RFQ responses tell you what a vendor wants you to know. Interview questions reveal what they actually know and how they actually operate. The following questions are designed to surface the difference between genuine security capability and practiced marketing responses.
“Walk us through the last security vulnerability you discovered in your own code. How was it found, who was notified, and what changed in your process afterward?”
This reveals detection capability, escalation culture, and whether they learn from incidents. A vendor who cannot cite a specific example has either not found vulnerabilities or is not being transparent.
“If we gave you access to our production environment tomorrow, what would you do in the first 30 days to understand our security posture?”
Tests whether the vendor has a structured onboarding security assessment process or whether they would just start building without evaluating the existing risk landscape.
“Describe the last time a client asked you to do something you considered a security risk. What happened?”
Reveals whether the vendor has a security-first culture or a client-first culture. The correct answer involves respectful pushback, documented risk acceptance, and a clear process for handling disagreement.
“Which OWASP Top 10 vulnerabilities have you encountered most frequently in your work, and how do you test for them?”
Tests applied knowledge, not just certification awareness. Engineers who build secure software know which vulnerabilities appear most often in their specific domain and test for them deliberately.
“How do you handle a situation where a new CVE is published in a dependency that is already in production for a client?”
Reveals post-deployment security responsibility. The expected answer includes automated CVE monitoring, client notification within a defined window, and a prioritized patching process with evidence of completion.
“Tell us about the last penetration test you commissioned for a project similar to ours. What were the significant findings and what was remediated?”
Confirms direct experience with independent security testing, willingness to disclose real findings, and ability to act on them. Refusal to share any details is a significant red flag.
If you are evaluating vendors for a regulated environment and want to benchmark your RFQ process against a team that has operated in high-compliance environments, Hoyack’s AI Vibe Code Audit and Enterprise Solutions practice can provide an independent technical assessment of any vendor’s codebase or security posture before you sign a contract.
U.S. High-Risk Industry Software Clusters
The geography of secure software development in the United States follows the geography of regulated industries. Understanding where the concentration of regulated-industry software development expertise exists is relevant to both vendor sourcing and to understanding the local compliance culture that shapes how vendors operate.
One of the largest concentrations of defense and cybersecurity contractors in the country, driven by JBSA and NSA Texas. Strong onshore secure development talent. Hoyack is headquartered here.
Dominant in energy sector software with significant healthcare IT presence driven by the Texas Medical Center. Vendors here are accustomed to operating under strict safety and compliance requirements. Hoyack serves Houston clients directly.
The densest concentration of FedRAMP-authorized vendors and cleared developers in the country. Essential for federal civilian agency and intelligence community software procurement.
Life sciences and medtech software hub with deep HIPAA and FDA software validation expertise, anchored by the concentration of research hospitals and biotech firms.
The financial services software capital of the U.S. Vendors operating here are subject to the NY DFS Part 500 cybersecurity regulation, which sets a high compliance bar.
Rapidly growing healthcare IT cluster driven by the concentration of hospital management companies, payer organizations, and health data companies headquartered in the region.
Defense and aerospace software hub anchored by Redstone Arsenal and NASA Marshall Space Flight Center. Vendors here operate under CMMC and ITAR requirements as baseline.
Financial services technology hub with deep expertise in trading systems, risk management software, and insurance technology operating under strict CFTC and state regulatory oversight.
Data residency requirements in regulated industries often make onshore U.S. development a legal necessity rather than a preference. The Carnegie Mellon Software Engineering Institute research on software assurance notes that geographic and jurisdictional factors are increasingly material to software supply chain risk assessments for regulated organizations. Hoyack’s Strategic Onshore Partnership model is built around this requirement.
Scoring and Selecting the Right Vendor
A vendor who scores well on price and feature capability but poorly on security and compliance is not a viable option for a high-risk industry engagement. Build your scoring model to reflect this reality before you receive vendor responses, not after.
| Evaluation Category | Recommended Weight | Scoring Method | Minimum Threshold |
|---|---|---|---|
| Security Certifications and Compliance | 30% | Pass/fail on Critical items; scored on High items | All Critical items must pass. Failure = disqualification. |
| Secure Development Process | 25% | Documented evidence required for each item | Written SSDLC, SAST, and vulnerability SLAs are non-negotiable. |
| Data Handling and Access Controls | 20% | Evidence-based scoring with third-party verification | Encryption standards and RBAC must meet or exceed your industry baseline. |
| Incident Response and Business Continuity | 15% | Written plan review plus interview scoring | Breach notification SLA must meet your regulatory requirement. |
| Team and Personnel Security | 10% | Policy review and reference validation | U.S.-based delivery required for projects involving restricted data. |
Before finalizing any vendor selection, conduct a reference check with at least two clients from the same industry segment as your project. Ask references specifically about security incidents that occurred during the engagement, how the vendor responded, and whether they would select the same vendor for a more security-sensitive project.

Frequently Asked Questions
What is secure software development?
Secure software development is the practice of integrating security controls, testing, and compliance requirements throughout every phase of the software development life cycle, from requirements gathering through deployment and maintenance. It goes beyond standard coding practices to include threat modeling, static and dynamic analysis, dependency scanning, and audit trail requirements. Application development security best practices require that security is treated as a design property, not a QA step.
What certifications should a secure software development vendor hold?
At minimum, a vendor serving high-risk industries should hold SOC 2 Type II certification. Depending on your industry, you may also require ISO 27001, CMMC Level 2 or 3 for defense contracts, HIPAA technical safeguard compliance documentation, or PCI DSS assessment reports. Ask for the actual audit reports, not just self-attestation. Software security standards like NIST SP 800-218 provide the baseline framework for federal and regulated-industry vendor requirements.
What is the NIST Secure Software Development Framework?
The NIST Secure Software Development Framework (SSDF), published as NIST SP 800-218, is a set of fundamental practices for secure software development organized into four groups: Prepare the Organization (PO), Protect the Software (PS), Produce Well-Secured Software (PW), and Respond to Vulnerabilities (RV). Federal agencies and their contractors are required to attest to SSDF conformance under OMB Memorandum M-22-18. The SSDF is also increasingly referenced in commercial and regulated-industry vendor due diligence requirements.
How do I evaluate a vendor’s secure development process?
Request a written description of their Secure Software Development Life Cycle (SSDLC). Key indicators include: formal threat modeling during design, mandatory code review policies, automated SAST and DAST tooling in every CI/CD pipeline, a documented vulnerability disclosure and remediation process, dependency management practices, and third-party penetration test records for comparable projects. Vendors who cannot provide written documentation for each of these practices do not have a mature secure development program regardless of what their marketing materials claim.
Should I require U.S.-based developers for a regulated project?
For most regulated industries, yes. Data residency requirements under HIPAA, ITAR, CUI handling requirements under CMMC, and FedRAMP boundary controls often make offshore access to project systems a legal compliance issue, not just a preference. Beyond legal requirements, U.S.-based development eliminates time-zone coordination overhead, aligns team members with the same regulatory culture, and simplifies incident response escalation. Hoyack’s Finance Industry and Healthcare Industry practices operate exclusively with onshore U.S. engineers.
How often should we re-evaluate our software development vendor’s security posture?
At minimum annually. Best practice for high-risk industries is to request updated SOC 2 reports annually, conduct an annual review of the vendor’s security documentation, and perform a brief security assessment whenever there is a significant change in the engagement scope, the vendor’s team composition, or the vendor’s technology stack. For long-running engagements, consider requiring the vendor to notify you of material changes to their security posture, certifications, or key security personnel as a contract obligation.
