Chatbot Security Assessment
Security assessment for chatbot and conversational AI systems
Our Chatbot Security Assessment tests a conversational AI system the way its users — and its abusers — actually reach it: through the conversation. We test whether the chatbot can be talked out of its rules (prompt injection and jailbreak), whether it leaks data from its context or from another user's session, whether its safety guardrails can be bypassed, and whether the backend actions it can trigger are properly gated. The work follows the OWASP Top 10 for LLM Applications and the OWASP AI Testing Guide, and draws on MITRE ATLAS. Because Persian text can slip past a filter tuned for English without changing what the model understands, we test the language-specific evasions too. Every finding is proven, rated with CVSS alongside its real impact, and written up with a concrete fix.
What's Included
Prompt injection and jailbreak against the conversation guardrails
Language-specific evasion: character variants, zero-width characters, and mixed-script obfuscation in Persian
Sensitive data leakage from the system context, the knowledge base, or another user's session
Safety and brand-guardrail bypass: unsafe, off-policy, or reputationally damaging output
Session and state handling: history bleed, cross-session leakage, and identity confusion
Backend integration: actions the chatbot can trigger, and whether they are authorized and gated
Input validation and output handling where the reply reaches another system
Authentication and authorization of the user behind the conversation
Privacy and PII handling in prompts, logs, and transcripts
Unbounded consumption: cost and denial-of-service through the chat interface

Frequently Asked Questions
It evaluates a conversational AI system for security weaknesses reached through the conversation — prompt injection and jailbreak, data leakage, guardrail bypass, session flaws, and the security of the backend actions it can trigger — following the OWASP Top 10 for LLM Applications and the OWASP AI Testing Guide, with each finding proven and rated.
Jailbreak is getting the model to ignore its own safety rules — to say what it was told not to say. Prompt injection is getting it to follow an attacker's instruction over the application's, often through content it reads rather than a direct request. They overlap, and a chatbot assessment tests both.
Many safety filters are tuned for English. Persian character variants (ی/ي, ک/ك), zero-width characters, mixed script, and Finglish can change what the filter sees without changing what the model understands, letting a payload through. An assessment that only tests English misses these, so we test the Persian-specific evasions directly.
Yes — through its system prompt, its knowledge base, or the history of another user's session if state is not properly isolated. We test whether the chatbot can be led to reveal its instructions, retrieve documents the user has no right to, or carry information across sessions.
We test the boundary: where the chatbot can trigger a backend action, we check that the action verifies who is asking and stays within their permissions. A full assessment of the backend systems themselves is a separate scope we can add, but the chatbot-to-backend gate is part of this service.
Conversational testing is largely safe, but tests that could trigger a real action or reach real customer data are agreed in advance and run carefully. We prefer a staging instance that mirrors production, and when we must test the live system we set limits and keep a contact on your side to pause at once.
Each finding gets a CVSS score for a common baseline, adjusted by the real impact — what it leaks or triggers, how easily, and whether it crosses a user boundary — and is mapped to the OWASP Top 10 for LLM Applications. A guardrail slip that only affects tone is not the same as one that reaches customer data.
Duration depends on the chatbot's complexity — its knowledge base, its backend actions, and the languages it serves. A typical assessment runs about one to three weeks, and we give a firm estimate after scoping. Re-testing after you remediate is included.
