PromptBrake vs DefenceNet
PromptBrake and DefenceNet serve fundamentally different security needs. PromptBrake is the right choice for engineering teams that need to validate LLM endpoint security before shipping AI-powered products. DefenceNet is the right choice for enterprises and telcos that need real-time phishing detection across email, SMS, and web channels. These tools do not compete directly and could complement each other in a comprehensive security stack.

Frequently Asked Questions
Do PromptBrake and DefenceNet solve the same security problem?
No. PromptBrake focuses on testing LLM endpoints for prompt injection, data leaks, and tool misuse. DefenceNet detects and blocks phishing URLs, smishing, and malicious links across SMS, email, and web. They address entirely different threat categories and could be used alongside each other in a layered security strategy.
Can I use PromptBrake if I do not have an AI-powered application?
PromptBrake is designed specifically for teams running LLM-powered endpoints (OpenAI, Claude, Gemini, or compatible APIs). If your application does not use a language model API, PromptBrake would not be applicable. DefenceNet, on the other hand, protects any organization against phishing regardless of whether they use AI internally.
Which tool offers on-premises deployment?
DefenceNet offers a full containerized on-premises deployment option with zero external data egress, suitable for telcos and government organizations that require data sovereignty. PromptBrake operates as a cloud-only SaaS that connects to your AI endpoint externally and does not require any local installation.
How does pricing compare between the two tools?
PromptBrake publishes transparent pricing: Scout at $79/mo for 18 scans and Pro at $149/mo for 25 scans with CI/CD integration. DefenceNet uses enterprise pricing and requires contacting their sales team for a quote, which is common for tools designed to scale to telecom-level throughput.
Can these two tools be used together?
Yes. Since they address different security domains, organizations building AI applications that also need phishing protection could deploy both. PromptBrake would secure the LLM endpoints in the development pipeline, while DefenceNet would protect end users and employees from phishing attacks across communication channels.
