I just launched xonPlus, and I wanted to share the story behind it. This started as a side project and turned into something that solves a real, frustrating problem for security teams.
🛠️ The Backstory
For the past few years, I’ve been running XposedOrNot, an open-source platform that helps individuals check if their email has been involved in a data breach.
It began as a learning exercise, but something unexpected happened.
Security teams from startups, SMBs, and even large enterprises started reaching out.
They weren’t looking to check a single email.
They wanted to monitor entire domains, get real-time alerts, and feed that data into their incident response workflows.
At first, I built custom scripts. Then, quick dashboards.
But it became clear that what they needed was not another SIEM or threat intel feed.
They needed something faster, more focused, and much lighter.
🔍 What I Built
xonPlus is a real-time breach alerting system for companies.
It focuses on one key job:
👉 Letting you know as soon as your team’s credentials show up in public breaches, paste sites, or dark web forums.
This is not about prevention.
It is about early detection, which often makes the difference between quietly fixing something or managing a full-blown incident.
You can integrate it easily with:
Teams
Slack
Splunk
Or just use the API and plug it into your workflow
đź’Ľ Use Cases We Support
xonEnterprise – Real-time domain-wide monitoring for security teams
xonConsumer –Give your customers the power to outsmart breaches
xonAPI – Breach visibility for dev teams building their own apps or security tools
All of this is priced to be accessible, around 5 to 10 times more cost-efficient than other solutions we looked at.
📦 Who It’s For
Startups and SMBs that don’t have a full SOC
Security teams who want better visibility
Developers looking to embed credential alerts into tools
Anyone tired of finding out too late
🔗 What’s Next
xonPlus is available as a monthly SaaS product with no long-term contracts.
I’m continuing to add features based on what early users are asking for, especially around integrations and automation.
