Is My Cursor App Secure?
Cursor is a code editor, not a hosting platform — so your app's security depends on your code, not Cursor itself. Cursor is SOC 2 Type II certified and offers Privacy Mode to prevent code from being stored by AI providers. The main risk is AI-generated code with security flaws that you deploy without reviewing.
Why this matters
Unlike Lovable, Bolt, or Replit, Cursor does not host or deploy your app. It helps you write code faster. The security question is whether the AI-generated code it produces is safe to deploy, and whether your source code is protected while using the tool.
What's at stake
AI-generated code can contain subtle security flaws — missing auth checks, exposed credentials, or insecure API patterns. If you deploy without reviewing, you inherit those vulnerabilities.
Your checklist.
AI-generated code has been reviewed for security flaws
CriticalCursor's AI can generate code with missing authorization checks, hardcoded credentials, or insecure patterns. Review all security-critical code before deploying — especially auth flows, API routes, and database queries.
Privacy Mode is enabled if working with sensitive code
CriticalPrivacy Mode ensures zero data retention with AI model providers. Your code is not stored or used for training. Enable it for proprietary or sensitive projects.
API keys and secrets are not hardcoded in generated code
CriticalAI code generation can sometimes include placeholder API keys or suggest hardcoding credentials. Always use environment variables and check generated code for exposed secrets.
.cursorrules is configured for security-aware generation
ImportantUse .cursorrules or SKILL.md files to instruct the AI to follow your security patterns — like always using parameterized queries, never hardcoding secrets, and including auth checks on API routes.
Codebase indexing settings are reviewed
RecommendedCursor stores obfuscated code embeddings for codebase indexing. If this concerns you, disable codebase indexing in settings. File names are obfuscated but metadata is stored.

Frequently asked questions.
Cursor sends code context to AI model providers to generate responses. In Privacy Mode, these providers have zero data retention — your code is not stored or used for training. Cursor is SOC 2 Type II certified and conducts annual penetration testing.
Yes. Like any AI code generation tool, Cursor can produce code with security flaws — missing auth checks, SQL injection vulnerabilities, or hardcoded credentials. Always review security-critical code before deploying.
Cursor Blame (Enterprise plan) extends Git blame with AI attribution. It shows which lines were AI-generated vs. human-written, linking each line to the conversation that produced it. This helps you identify and audit AI-generated code during security reviews.
Cursor is different — it is a code editor, not a full-stack builder. It does not host your app, manage your database, or handle deployment. This means fewer attack surfaces from the tool itself, but you are fully responsible for the security of the code it helps you write.
