Prompt Injection Testing

Prompt injection matters when injected instructions change what the system reveals, retrieves, writes, calls, or executes. SCS tests prompt injection in the context of the deployed architecture.

Prompt Injection Testing.

Secure Consulting Solutions (SCS) provides prompt injection testing for LLM applications, RAG systems, AI agents, tool workflows, internal copilots, and enterprise Copilot scenarios.

The assessment validates whether direct prompts or indirect instructions in retrieved content can change what the system reveals, retrieves, calls, writes, or executes.

Deliverables include confirmed behavior, reproduction paths, raw output, tool or retrieval evidence where applicable, remediation guidance, and retest cases.

Assessment summary
Identity Which users, roles, workflows, or data sources can influence model behavior.
Evidence Prompts, assistant output, retrieved content, tool calls, citations, logs, and workflow effects.
Risk Instruction override, hidden prompt exposure, tool manipulation, policy bypass, and unsafe output handling.
Deliverable Executive summary, technical report, reproduction steps, findings CSV, remediation guidance, and retest plan.

What this assessment answers

  • Can direct user input override intended behavior?
  • Can retrieved documents, emails, files, or web content inject instructions indirectly?
  • Can injection trigger tool calls or unsafe actions?
  • Can the system leak hidden instructions or sensitive context?
  • Do guardrails fail differently across roles or workflows?

What we test

  • Direct prompt injection
  • Indirect prompt injection through external content
  • System prompt extraction
  • Encoding and obfuscation attacks
  • Policy bypass
  • RAG document injection
  • Agent tool manipulation
  • Unsafe output handling

How findings are reported

  • Confirmed behavior and reproduction path
  • Raw output and relevant context
  • Tool or retrieval evidence where applicable
  • Severity and business impact
  • Remediation guidance
  • Retest cases

SCS Approach

Operator-led, evidence-first assessment.

SCS does not report prompt injection because a phrase produced a surprising answer. A finding needs evidence that the application behavior, data boundary, or workflow assumption failed.

Common Buyer Questions

Prompt injection testing questions.

Q

What is prompt injection testing?

It is an assessment of whether user input or untrusted retrieved content can override intended instructions, expose sensitive context, or drive unsafe system behavior.

Do you test indirect prompt injection?

Yes. SCS tests instructions embedded in retrieved documents, web content, emails, files, or other data sources when those inputs are in scope.

What makes a finding valid?

A finding needs evidence that application behavior, data exposure, tool use, or a workflow assumption failed. A strange answer alone is not enough.

Can this be tested without production data?

Often, yes. Test targets, approved samples, seeded markers, and scoped accounts can support assessment while limiting sensitive production exposure.

Need evidence, not a generic scan?

SCS scopes AI security assessments around architecture, identities, data paths, evidence, remediation, and retest.
