Software security you can build, test, and prove

Three practices that cover the software, the program that produces it, and the engineering work of improving both.

How the Work Fits Together

Assess, Identify Gaps, Implement, Validate

Engagements are scoped and bought individually. They are designed to connect, so an assessment can flow straight into the work it identifies rather than stopping at a report.

Step 01

Assess

Test the product and examine the program behind it, including the evidence sitting behind each control.

Step 02

Identify Gaps

Separate what is missing from what exists but cannot be demonstrated. Both are gaps, and they need different fixes.

Step 03

Implement

Build the controls, automation, and architecture changes in your stack, with tests and handover.

Step 04

Validate

Re-test, re-examine, and confirm the control operates. A gap closes on evidence, not on assertion.

Application & AI Security

Find and reduce risk in the software itself.

Testing and review for applications, APIs, and AI-backed features, run against a threat model and closed out with a verification pass.

  • Application Security Assessments
  • AI and LLM Security Reviews
  • Penetration Testing
  • Threat Modeling
  • Security Architecture Reviews
  • Source Code Reviews
  • Software Supply-Chain Reviews
  • Adversarial Security Testing

Software Security Assurance

Build a defensible software-security program and prove that it operates.

Assessment, evidence, and validation for the program behind the software. Starts with the Software Security Evidence Readiness Assessment.

Security Engineering

Turn security recommendations into working controls.

The implementation half of the work: pipelines, automation, architecture, and remediation, built in your stack and handed over with documentation.

  • CI/CD Security
  • Security Automation
  • Secure Architecture Design
  • Remediation Engineering
  • SBOM Automation
  • Software Supply-Chain Controls

Who This Is For

Who We Work With

The work suits organizations where software is the product or sits in the critical path, and it usually starts with one of the roles below.

Organizations

  • Software companies and SaaS providers
  • AI companies and teams shipping LLM-backed features
  • Technology organizations with software in the critical path
  • Product manufacturers with software or firmware in the product
  • Companies selling software into enterprises or government
  • Organizations affected by software-security regulation

Who usually brings us in

  • CISO, CTO, and CIO
  • VP and Director of Engineering
  • Head of Product Security or Application Security
  • Security engineering and platform leadership
  • Product leadership answering customer security reviews
  • Founders and executives preparing for diligence
Questions

Frequently Asked Questions

A few of the questions we hear most often, and how we tend to answer them.

Application & AI Security answers whether a given system is secure. Software Security Assurance answers whether the organization has a program that reliably produces secure systems, and whether you can show it. Security Engineering builds the controls that close the gaps identified through either of the other two practices. Many clients start with one and move into another once they see what the first one surfaced.
No. Every service is scoped and bought individually. If you need a test because a customer asked for one, that is an Application & AI Security engagement and it can stand alone. The practices connect when it helps you, not as a bundling requirement.
No. It is an independent advisory assessment mapped to public frameworks, and it produces a scored picture, a gap analysis, and a roadmap. 717 DEV is not a certification body and does not issue certificates. Where you need a formal certification or an audit from an accredited body, we can help you prepare for it, but the certificate comes from them.
Start with the basics: prompt injection, jailbreak resistance, output handling, and how the model is exposed through your API. Beyond that, model the threats specific to your architecture, including prompt or data exfiltration, tool-use abuse, retrieval manipulation, and chained-call escalation. We review the design, test what matters, and document residual risk in language the rest of the business can act on.
We build it. Security Engineering is implementation work: pipeline gates, security automation, SBOM and signing, remediation, and application engineering where the security properties are the point, such as authentication and authorization systems, multi-tenancy, and audit logging. 717 DEV has shipped production software for years, and the engineers who write it are the ones who do the security work.
