When a vendor’s logins leak, attackers can walk into your business through the side door. Enter a vendor and the exact login you use there, and we will tell you if that specific credential is exposed. Create a free account to run the check.
Free account, no credit card. Your free plan includes a single one-time check: one vendor login, email, or domain.
Supply-chain and vendor credential theft is one of the most common ways small businesses get compromised. You cannot fix your vendors' security, but you can see when their exposure puts you at risk.
You do not run your vendors' security. But when their logins leak, attackers can use them to reach your data, systems, and money.
A breached supplier account sends you a fake invoice or a bank-detail change that looks completely legitimate, because it comes from a real, trusted address.
A vendor login reused elsewhere, or shared across your team, turns one leak into many open doors.
Free checkers mostly cover old public breaches, and only by email. GuardPilot checks by domain, email, or username, across the places business logins actually surface first.
Known breach dumps and combolists that leak email-and-password pairs from hacked services.
Credentials copied straight from infected devices. The fresh, dangerous category most free tools miss.
The criminal markets where stolen business and vendor logins are bought, sold, and tested.
Type the vendor's domain or email, plus the exact username or email you sign in with there, then create your free account.
GuardPilot checks breach data, infostealer logs, and dark-web markets for that specific credential.
We flag whether that login is exposed at the vendor or elsewhere, then our AI explains it and guides the fix.
Most tools hand you a list of leaks and leave. GuardPilot is the AI Incident Response Platform for Credential Exposure: it investigates each exposure, explains it in plain English, guides the fix, and keeps watching your vendors so you are alerted the moment a new login leaks. Learn more in how vendor email compromise works.
Yes. You are checking whether a vendor's domain, email, or login already appears in known data breaches, infostealer stealer logs, and dark-web marketplaces. This is exposure that is already circulating publicly. We only ever show counts, breach names, and dates, never the actual password.
Your security is only as strong as the vendors you connect to. A breached supplier login can be used to send you a convincing fake invoice, reach shared systems, or move laterally into your accounts. Vendor and supply-chain credential theft is one of the most common ways small businesses get hit.
Yes. You create a free account (no credit card) to run it, and your free plan includes a single one-time check: one vendor login, email, or domain, monitored continuously at no cost. You can upgrade to check and watch more vendor logins and whole domains across your business.
No. We detect exposure using hashes and metadata, and we never store the actual password or send credentials to the AI. The check tells you that a credential leaked and how serious it is, not what the password is.
Rotate any credentials you share with that vendor, turn on two-factor authentication, verify any change to bank or payment details by phone before acting, and monitor continuously so you know the moment a new leak appears. If you sign up, our AI explains each exposure and walks you through the fix.
Run a free check now, then let GuardPilot watch your vendors and your own logins around the clock.
