Solutions
Every way fraudulent users reach your product, and what stops each one.
Fake signups, recycled trials and temporary email addresses are different problems with one root cause: you cannot tell who is on the other side of the form. SaaS fraud prevention at Trueguard treats them as one signal set, so you can pick the problem you have today and the same integration covers the rest.
No credit card required - free tier availableSignup fraud prevention, by problem.
Free trial abuse prevention
Detect the same person returning for another trial under a new email address, after a cookie clear or behind a VPN.
Fake account detection
Score automation behaviour, device and network origin so bot registrations never reach your database.
Disposable email detection
Block temporary and alias inboxes at signup with a registry that updates as new temp-mail services appear.
Email validation
Check deliverability, role-based addresses and syntax in one call, at signup or across a list you already have.
Start from the symptom you can measure.
Most teams arrive at signup fraud prevention with a number that looks wrong rather than a fraud category. Find the one you are seeing.
| What you are seeing | Signal that explains it | Where to start |
|---|---|---|
| Trial signups up, conversion flat | Multiple accounts per device | Free trial abuse prevention |
| Hundreds of accounts in minutes, none active | Bot score, datacenter origin | Fake account detection |
| Onboarding emails bouncing | Disposable email | Disposable email detection |
| Infrastructure spend growing faster than revenue | Free tier consumed by repeat signups | Free tier detection |
| Promotions and referral credits drained | Device reuse, alias addresses | Multi-accounting detection |
| A contact list you can no longer email | Undeliverable and role-based addresses | Email validation |
One integration, every signal.
You do not pick signals at install time. The snippet collects a verification ID on your signup page, your backend calls one endpoint, and the response carries the device, network and email signals together with the action your rules decided. Turning on another solution later is a rule change, not a migration.
