You shipped it. Now make sure no one breaks it.
Congrats on your launch. A public launch also means bots, scrapers and script-kiddies probing your app within hours. Silker adds a runtime security layer in 5 minutes - npm install, one line, zero changes to your logic.

Free security scan + 3 months Pro free
We run a free, non-invasive scan of your launched product and send you a short report of what we found. Hook up the SDK and you get 3 months of Silker Pro free - full dashboard, AI Verdict, threat map and pentest tools. No credit card.
Two layers, both live in minutes
Protect your app & API with the SDK, and your website & landing page with Shield - one script tag.
Runtime protection for your backend
Inspects every request in ~0ms. Clean traffic passes through; malicious requests get blocked and logged to your dashboard. Deploy it the way that fits your stack:
Node / Next.js / Express - one line of middleware.
Any stack (PHP, Python, Go, Java, Ruby) - sidecar, zero code changes.
Protect at the edge, before traffic reaches your origin.
SQL injection & XSS
Blocked inline in ~0ms before they hit your handler.
Prompt injection / jailbreak
Heuristics + AI Verdict layer for your LLM routes.
Data & secret leaks
PII, API keys and tokens redacted or blocked in responses.
Rate limiting & IP bans
Brute-force and bot abuse stopped, synced to your dashboard.
Path traversal
Stops ../ and encoded attempts to read files outside your app.
Malicious file upload
Catches web shells and disguised payloads at the upload route.
SSRF (outgoing fetch)
Flags calls to internal IPs and cloud metadata endpoints.
IDOR & access control
Opt-in checks for broken object-level authorization.
...plus CSRF, host-header injection, session anomalies, vulnerable components, compliance and more - full OWASP-aligned coverage.
Protect your launch page with one script tag
Your Product Hunt traffic lands on a marketing site or app shell. Shield drops a customisable trust badge plus client-side monitoring into any page - no backend, no env vars. Paste one <script> into your <head> and you are live in 30 seconds.
Embed served from https://extra-api.silkerai.com/shield/embed.js
We position Silker as your first layer, not "complete protection" - and we publish exactly what we catch and what we don't. See the public benchmark.
