What you will put in place
- Give vendors the same scope, time window, and success criteria.
- Assess evidence and review effort alongside the number of findings.
- Separate product capability, contract terms, and your pilot observations.
Define the job you are buying the tool to do
Start with the program constraint: incomplete application coverage, a backlog nobody trusts, slow remediation, weak external asset visibility, or a lack of leadership evidence. Different products can overlap while serving different primary workflows. Make those workflows explicit before comparing feature lists.
NIST SSDF supports a common vocabulary for discussing secure development with suppliers. Use it to describe the outcomes you need, then ask vendors to show the relevant workflow in your environment. A checklist response and a working integration are different kinds of evidence.
- In-scope systems: representative languages, repositories, cloud accounts, and environments.
- Users: engineering reviewer, AppSec reviewer, platform owner, and executive stakeholder.
- Required outcomes: reviewable findings, a remediation path, verified closure, and exportable records.
- Constraints: code handling, deployment requirements, access approval, and release windows.
Run a pilot that supports a fair decision
Select a small set of representative applications and agree on access before the pilot begins. Record the exact revisions and configuration each vendor reviews. Give each provider the same documented context, scope, and review window; log any differences that affect interpretation.
Use existing internal findings whose status your team understands, normal code changes, and reviewed examples from your own authorized environment. Evaluate whether the reports explain known risk and whether the workflow handles a fix. A small pilot cannot establish detection coverage for every vulnerability class or justify a universal accuracy percentage.
Have your own reviewers assess results before looking at vendor summary statistics. Record actionable findings, unresolved reports, duplicates, and reviewer dismissals with reasons. Keep tool execution errors outside the finding-quality denominator.
Score evidence, workflow, and control
Use a simple evidence scale for each criterion: 0 means unverified, 1 means shown in documentation or a demo, and 2 means observed in your pilot. Add a separate pass/fail column for mandatory requirements. Do not let a high total score compensate for a failed data-handling or access requirement.
| Criterion | Evidence to request | Your reviewer |
|---|---|---|
| Relevant coverage | Supported artifacts plus successful runs and documented exclusions on your scope | AppSec + platform |
| Finding quality | Affected revision, supporting trace or rationale, impact, and verification limits | AppSec |
| Review effort | Reviewer time per unique report and the reasons for dismissals | AppSec + engineering |
| Remediation | A proposed fix your team can review and a recorded verification result | Engineering |
| Operational reliability | Check failures, recovery path, ownership, and release impact | Platform |
| Data handling | Data flow, retention, subprocessors, model use, deletion, and access controls | Security + privacy |
| Governance | Roles, exception history, finding ownership, and exportable records | Security lead |
| Commercial scope | Included modules, usage units, overages, services, and exit terms | Procurement |
Finish the enterprise review before expanding access
Map where source code, findings, logs, and credentials travel. Ask which parties can access each category and which contractual terms govern it. Request documentation for retention and deletion, model providers and model-training use, hosting regions, subprocessors, identity controls, and incident notification.
Test the access model with the roles your team will actually use. Review repository permissions, workspace separation, SSO requirements, export permissions, and the audit events available to your operators. Confirm any deployment or residency requirement against the proposed edition and contract.
Public trust pages and certifications can inform the review, but your approval needs the actual scope, dates, and documents relevant to the service you will buy. Record open questions and the owner who must resolve them before onboarding additional systems.
Compare total operating cost with transparent assumptions
Subscription cost is one input. Include setup time, recurring reviewer time, engineering remediation time, training, services, and any usage charges that apply to your planned scope. Keep existing tool costs separate until you have confirmed which contracts can be retired.
Estimate time savings from your pilot observations and label the assumptions. Time returned to a team is useful capacity; it becomes a budget saving only if your organization can realize it. Avoid treating the estimated financial impact of a hypothetical breach as guaranteed ROI.
