Security built for AI-built apps
WAFs were designed for a different era. Silker runs where your app runs - as an SDK, a Cloudflare Worker or a Docker proxy - and catches the prompt injections and data leaks a WAF never sees.
Why a WAF isn't enough
Context blindness
Standard firewalls look for SQL keywords but miss natural-language attacks. They can’t tell a user asking about code from a user injecting it.
They don’t see data leaving
A WAF inspects requests coming in. It doesn’t catch secrets, API keys or PII flowing out of your app - the failure mode that sinks AI-built apps.
New attack vectors
Prompt injection, jailbreaks and token smuggling bypass regex filters. You need detection built for adversarial AI inputs.
Deploy where your app already runs
One line in any Node or Next.js app, or a Docker proxy in front of any other stack (Java, Python, Go, PHP). No re-architecture.
AI-aware detection, on your infra
Beyond keyword matching: we inspect request structure and your LLM routes to flag prompt injection and data leaks. Detection runs in your runtime - your traffic never passes through us.
Privacy by design
Your data stays yours. Silker is built so the sensitive parts never leave your infrastructure.
PII redaction
Sensitive data is redacted before anything is logged or sent to the dashboard.
Built for GDPR
Designed with EU data rules in mind. SOC 2 Type II is on our roadmap, not yet certified - and we'll say so until it is.
