Stop Account Takeovers Before They Start
SubscriptionSecurity156 impressions#1921 of its week
Every day, new breaches expose millions of credentials, and that puts your organization at risk of account takeovers and ransomware attacks. xonPlus changes the game by watching your email addresses and domains against fresh breach data, so you know the moment your data appears anywhere it shouldn't.
The platform works with your existing security tools like SIEM, SOAR, and ticketing systems, sending you real-time alerts with the intelligence you need. You'll know exactly which accounts got compromised, what data was exposed, and what to do about it. Plus, everything's customizable to cut down on alert noise and keep your team focused on the threats that matter.
We built xonPlus on the proven XposedOrNot foundation that's been tracking breach intelligence for over 5 years. You get transparent monthly pricing and detailed compliance reporting for GDPR, ISO 27001, and other frameworks. It's designed for security teams who want to stay ahead of threats without dealing with complicated setups or surprise billing.
xonPlus provides real-time breach intelligence alerts for email addresses and domains, integrating with security tools via API, JSON, CSV and webhooks.
