Detect. Track. Stop Content Theft — Automatically.
TheftSentinel quietly watches how your content is used across the web. If someone embeds, copies, hotlinks, or proxies your assets — you’ll know immediately, with evidence.
Built for publishers, SaaS platforms, and agencies who are tired of “finding out” after the damage is done. TheftSentinel gives you visibility first — and options second.
How it works
One tiny snippet. One invisible signal. One dashboard that tells the truth.
1) Embed
Add a lightweight script or 1×1 pixel to your pages, feeds, or embeds.
<script src="https://tfsn.io/sn.js" async></script>
2) Monitor
Every request is validated against your allowed domains and patterns.
signal(domain, ip, ua, ref, path)
3) Respond
Get alerts, export evidence, or automatically block abusive sources.
action = alert | flag | block
Designed for: hotlink protection, unauthorized embeds, content reuse tracking, affiliate/asset abuse, “borrowed” templates, and SaaS embed policing.
Live Intelligence
Show, don’t tell. Here’s what “visibility” looks like in practice.
Verification score
Each event gets a confidence score based on domain, headers, referrer, and pattern match.
Evidence-ready exports
Export filtered logs per domain/IP/user-agent with timestamps and request metadata.
CSV • JSON • Webhook payload
Response modes
Choose between “observe”, “notify”, and “enforce” — per domain, per path, or per embed token.
observe → notify → enforce
Interactive demo
Click “Simulate” to generate events. This is a front-end-only demo — no network calls.
Features
Everything you’d expect from a serious protection layer — plus the stuff you wish existed.
Domain whitelisting
Allow only approved domains to embed or load your assets — everything else gets flagged.
Hotlink protection
Detect direct image/asset hotlinking and respond with notify, redirect, or block.
1×1 tracking pixel
Track usage in emails, embeds, and templates with minimal footprint and clear attribution.
IP & UA intelligence
See the “how” behind abuse: IP, user-agent, country hints, and repeat patterns.
Admin activity logs
Know who changed what, when. Keep an audit trail for critical security actions.
Email alerts
Get notified when new domains appear, thresholds are crossed, or enforcement triggers.
Automatic blocking
Optional enforcement: block by IP/domain, return decoys, or require tokens.
API access
Pull evidence into your own systems, dashboards, or automated response workflows.
Performance promise
Built for high-traffic sites
- Designed to run quietly — it doesn’t compete with your Core Web Vitals.
- Event payloads are compact and can be rate-limited or sampled.
- Works with CDNs, edge caching, and strict CSP policies.
Who it’s for
Anyone whose business depends on assets staying where they belong.
Protect content
Spot unauthorized re-use and hotlinking before it becomes “the new normal”.
Guard embeds
Ensure widgets, iframes, and JS embeds are used only by approved customers.
Prove ownership
Client evidence packs with domain timelines, repeat offenders, and action logs.
Track abuse
See where your product widgets and images are being reused without attribution.
Enforce distribution
Control syndication rules and detect scraping or unauthorized mirroring.
Real threats
Content theft is silent — until it costs you money, rankings, or trust.
Most theft isn’t dramatic. It’s routine.
Hotlinking, copied templates, embedded widgets, “borrowed” product cards, mirrored landing pages — the small stuff adds up. TheftSentinel exists to make the invisible visible.
Recommendation: start in “observe” mode → collect evidence → then enforce.
Integration & control
Drop-in snippet. Optional pixel. API-first for teams who automate everything.
Minimal JS snippet
<script src="https://theftsentinel.example/sn.js" data-site="YOUR_SITE_ID" data-mode="observe" async></script>
1×1 pixel (email/embeds)
<img src="https://theftsentinel.example/pixel.gif?site=YOUR_SITE_ID&token=YOUR_TOKEN" width="1" height="1" alt="" />
The URLs above are placeholders — swap them for your endpoint. Everything on this page is demo-only.
API-first control plane
- /events — ingest signals with domain + metadata
- /rules — allowlists, thresholds, response modes
- /exports — evidence bundles for clients/legal
- /webhooks — notify Slack/email/internal systems
Example webhook payload
{
"ts": "2026-01-22T21:00:00Z",
"site": "YOUR_SITE_ID",
"domain": "suspicious-example.com",
"ip": "203.0.113.42",
"event": "embed",
"confidence": 0.82,
"action": "flag",
"evidence_id": "ev_9f3a..."
}
You don’t need lawsuits. You need visibility.
Start in observe mode. Collect evidence. Enforce when you’re ready.
