Before launch, verify the whole system: what data it can reach, what actions it can take, how it behaves under failure or attack, and how your team will detect and respond to problems. Readiness is a set of controls and operating practices matched to the app’s risks—not a badge or a promise that the model will never fail.
What “production-ready” should mean for an LLM app
Assess the application and its operations, not just the prompt or model call. The system includes the model provider, application code, retrieval sources, connected tools, permissions, deployment, monitoring, and the people responsible for support and response. A plausible answer on a happy path shows only that one interaction worked.

The OWASP Artificial Intelligence Security Verification Standard (AISVS) is one way to turn readiness into checks. Its official page describes testable requirements spanning the AI system lifecycle, including deployment, agent orchestration, monitoring, and retirement. The page reports 191 requirements across 12 chapters and three appendices in AISVS 1.0, released in June 2026. OWASP says “every requirement must be verifiable, testable, and implementable.” A standard can guide verification; using one does not by itself certify an application as ready.
Define the behaviors you need to verify
Start with the consequences of failure in your particular application. Write down what it should do when the model is wrong, refuses a request, times out, returns malformed output, or receives hostile instructions in its context. Turn important expectations into checks that can be repeated, rather than relying on a few successful demonstrations.
#1 Best Overall
Build representative tests
Test ordinary tasks alongside edge cases, policy constraints, and known attack patterns. Include the full path through retrieval and tools where applicable: a model response may look acceptable while the surrounding application exposes data or performs an unauthorized action. Use human review when the consequences of a mistaken or unauthorized action warrant it.
There is no universal accuracy score, pass rate, or evaluation set that establishes readiness for every product. Set acceptance criteria according to the tasks, risks, and users of your application, and document what the tests do and do not cover.
Rank #2
Repeat checks when the system changes
Before release, include application testing, source review, vulnerability assessment, and red teaming appropriate to the system. For agent-style applications, OWASP recommends structured security testing before production and after material changes to prompts, tools, memory, retrieval, policies, or model providers. Revisit functional, security, reliability, and robustness checks as dependencies and behavior change.

Map what information enters the application, where it is stored or sent, and which people and components can access it. Classify sensitive and proprietary data, then apply protections and access rules to those flows. The OWASP GenAI Security Project’s checklist covers data classification and protection alongside input and output security, vulnerability checks, supply-chain security, monitoring, and incident response.
Treat retrieved content and tool results as untrusted
User messages are not the only possible source of hostile instructions. Documents, webpages, emails, and tool results can contain text intended to manipulate model behavior. Retrieval and external integrations therefore expand the application’s trust boundary. OWASP’s prompt-injection guidance describes prompt injection as a vulnerability in LLM applications; prompt wording or a filter alone should not be treated as the security boundary.
Authorize every consequential tool action in application code
For each connected capability, ask what data it can access, whether it can read or change that data, and which user authorization applies in the current session. Keep permissions as narrow as practical. Validate tool calls against the user’s permissions and session context, validate parameters, and check outputs before rendering them or acting on them. Model-generated text should not, by itself, authorize a privileged operation.
Rank #4
- Can an untrusted document or tool result influence an action?
- Does the application enforce the user’s authorization when a tool is called?
- Can the tool do only what the feature needs, or does it have broader access?
- Can operators detect suspicious use and disable the capability quickly?
These are layers for reducing risk, not guarantees that injection or misuse can be eliminated.

Plan for monitoring and incident response
Decide what behavior and security signals matter, who receives alerts, and how a suspected incident will be investigated. Keep useful audit information, but avoid placing credentials or unnecessary sensitive prompt and response content in broadly accessible logs. OWASP’s Secure AI Model Ops and AI Agent Security guidance, together with its LLM application checklist, emphasize monitoring and response as part of operating the system—not tasks to add only after launch.
Prepare incident procedures before users depend on the feature. Identify who can investigate, what records they need, and which actions or integrations can be disabled in an emergency. Monitoring is useful only if the team can interpret the signals and take an appropriate action.

Include model providers, third-party components, infrastructure, and other service dependencies in release and ongoing reviews. Consider provider and component risks, available third-party evidence, and infrastructure resilience. A model call that works in a demonstration does not establish that the dependencies around it are adequately reviewed or resilient.
Use a checklist as a verification aid, not a verdict
OWASP’s LLM Applications Cybersecurity and Governance Checklist v1.1 is dated May 7, 2024, and its checklist for using or implementing LLM solutions covers concerns such as testing, data security, permissions, monitoring, supply-chain security, and incident response. OWASP’s AISVS offers a more explicitly verification-oriented catalogue of requirements. When choosing a framework or checklist, check whether it covers the wider application as well as model-specific risks, whether its requirements can be implemented and tested, whether it addresses retrieval and tools, and whether it includes deployment and ongoing monitoring.
