Frequently Asked Questions
Are PromptBrake and DefenceNet competitors?
No. PromptBrake tests LLM APIs for security vulnerabilities before deployment. DefenceNet protects users from phishing attacks at runtime. They address different threats at different phases of the security lifecycle.
What is prompt injection and why does it matter?
Prompt injection is an attack where malicious input manipulates an LLM into ignoring its instructions, leaking data, or performing unauthorized actions. PromptBrake tests for this with 60+ real attack prompts before your LLM API reaches production.
Does DefenceNet protect against AI-generated phishing?
DefenceNet uses ML-based URL analysis to detect phishing links, including novel attacks that traditional blacklists miss — relevant as AI-generated phishing becomes more sophisticated.
