Proof vs Snyk: security findings and requirement evidence
Snyk helps find and address security issues. Proof helps retain requirements and the evidence used to assess changes. A security fix often needs both a fresh scan and verification that the affected behavior still meets its obligations.
Start with the security question you need answered
Snyk's documented products scan application code, open-source dependencies, container images and infrastructure configuration for security issues.
Proof connects requirements, implementation, verification evidence and known issues. A requirement can express a security property, such as tenant isolation, or another behavioral obligation, such as data retention. Proof's checks and verification instruments still need a supported scope, suitable inputs and reviewed assumptions.
Security and correctness overlap. An authorization defect can violate both a security rule and a product requirement. Compare how the configured tools investigate that defect and preserve useful evidence, without assuming either one covers every vulnerability or every intended behavior.
Compare the work you need to do
Use the same repository change and acceptance criteria in each evaluation.
| Evaluation question | Snyk | Proof |
|---|---|---|
| What is the starting point? | Security scanning across the selected code, dependency, container and infrastructure products. | A requirement or known issue connected to its implementation and supporting checks. |
| What should a finding contain? | The affected asset, security finding and remediation context available in the chosen product. | The affected obligation, relevant code or evidence, observed failure where available, and remaining review work. |
| What follows a fix? | Repeat the relevant scan and inspect the updated finding status for the changed asset. | Rerun the relevant verification and retain the result with its scope. Closing a record alone is not an execution. |
| What must be verified in a trial? | Language, package ecosystem, deployment and scan-policy coverage for your project. | Requirement quality, supported verification path, evidence provenance and configured acceptance policy. |
Verify a security upgrade preserves the data boundary
Illustrative evaluation: a service upgrades a document-processing dependency to address a security finding. The upgrade also changes how document metadata is parsed. The service must continue to reject an export request when the document belongs to another tenant.
Repeat the relevant security scan against the actual dependency and application revision. Separately exercise exports for an authorized user, a different tenant and missing ownership metadata. Inspect the exported content and storage access, not only the response status.
A Proof trial can record the tenant rule, link the affected path and tests, and retain the observed evidence and any unresolved issue. An unchanged requirement does not make old results applicable to a new parser. Review the evidence basis explicitly; this page does not claim automatic invalidation for every dependency or environment change.
Choose the missing part of your workflow
Choose Snyk when your immediate need is security scanning and remediation across its supported asset types. Evaluate Proof when your team struggles to connect a fix or refactor to the product obligations, checks and evidence that must survive it.
Using both can make sense. Keep the security finding's identity and affected version alongside the behavioral regression evidence so that reviewers can see both decisions. Any transfer of Snyk results into a Proof workflow needs an explicit, tested mapping; this comparison does not advertise a dedicated connector.
A passing scan supports its defined security scope. A passing requirement check supports its specific predicate and inputs. Neither result alone establishes that the service is secure, compliant or ready for every deployment.

This page does not compare vulnerability detection rates, recommend removing security controls or report a completed product trial.
Evaluate Proof on your own evidence
Bring a recent security fix, the affected requirement and the evidence your reviewers used to accept it. We can scope how Proof would connect that decision to the implementation and a repeatable check.
