TrustSig vs DataDome
DataDome targets large enterprises with a managed motion. TrustSig delivers comparable invisible detection as a self-serve product with public pricing.
| Capability | TrustSig | DataDome |
|---|---|---|
| How you start | Self-serve, free, in minutes | Demo request and sales process |
| Pricing | Public, transparent, free tier | Quote-based enterprise contracts |
| User friction | None — fully invisible | Invisible, challenge on risk |
| Data residency | EU only (Germany) | Multi-region, US-aligned vendor |
| Detection method | Hardware-level deterministic signals | ML behavioural detection |
| Integration weight | Two npm packages, no infra change | Edge/server module deployment |
| Cookies / tracking | Zero cookies, zero PII | Sets cookies for device tracking |
| Server verification | Local — sub-millisecond, no network call | Managed edge decisioning |
Why teams pick TrustSig over DataDome
DataDome is a strong enterprise platform. The mismatch is the buying motion and the footprint — not everyone wants a contract and a managed edge module.
Start without a sales process
DataDome is bought through a demo and a contract. TrustSig is self-serve: create an account, integrate, ship — the free tier needs no card and no call.
Transparent pricing
Quote-based enterprise pricing makes budgeting hard. TrustSig's pricing is public, with a genuinely free tier that includes the full engine.
Lightweight integration
Two npm packages and a local verify, with no infrastructure changes — instead of deploying and operating a managed edge module.
EU single jurisdiction
TrustSig processes only in Germany, cookieless and with no PII — a clean GDPR answer rather than a multi-region enterprise data map.
Deterministic and local
verifyLocal() returns a clear verdict on your own server with no per-request call to a managed service.
Right-sized for SMB and product teams
You get invisible, hardware-level protection without enterprise overhead — and you can scale on transparent paid plans when you need to.
Add TrustSig in minutes
No edge module to deploy. Add the invisible scan on the frontend and a local verify on the server. Two npm packages, no infrastructure changes.
- Frontend — invisible scan
import { useTrustSig } from "@trustsig/react" function ActionForm() { const { scan } = useTrustSig() const handleSubmit = async () => { const response = await scan() await fetch("/api/action", { headers: { "X-TrustSig-Response": response?.token || "" }, }) } } - Backend — local verify
import { TrustSig } from "@trustsig/server" const ts = new TrustSig({ secretKey: process.env.TRUSTSIG_SECRET_KEY }) app.post("/api/action", async (req, res) => { const token = req.headers["x-trustsig-response"] // decision made locally — no managed edge call const result = ts.verifyLocal(token) if (result.action === "BLOCK") return res.status(403).json({ error: "Blocked" }) })

One check is a single verification request: a page view, form submit, or login attempt that TrustSig evaluates. You only spend a check when traffic actually hits a protected surface, so bot floods do not quietly drain your quota.
DataDome alternative questions
Yes. TrustSig is fully self-serve. The free tier — the complete threat engine and 50,000 requests/month — requires no sales call and no credit card.
The detection model is hardware-level and deterministic, and paid plans scale request volume with transparent public pricing. You start small and grow without renegotiating a contract.
Much lighter. There is no edge or server module to deploy and operate — two npm packages and a local verify call, with no infrastructure changes.
Only in Germany. TrustSig is cookieless, stores no PII, and is GDPR Article 25 by design.
The complete deterministic threat engine and 50,000 requests per month, with no credit card.
