Self-hosted security framework that watches user activity inside your application to catch account takeover, fraud and abuse.
Most breaches do not arrive through the network perimeter. Tirreno is a security framework that sits inside your product and reads the events it generates, so compromised accounts and application logic abuse surface in the one place firewalls, WAFs and SIEM tools never look.
The application is hand-written PHP backed by PostgreSQL, with few dependencies and a five-minute install. You send events through the API or through one of the trackers for PHP, Python, Node.js and WordPress, and a real-time threat dashboard fills in immediately.
The moving parts are deliberately few.
- Rule engine: risk scores are calculated automatically from preset rules or from ones you write for your own product.
- Single user view: behavior patterns, risk scores, connected identities and an activity timeline for one account.
- Review queue: threshold settings suspend risky accounts automatically or flag them for a human to look at.
- Field audit trail: changes to important fields are tracked, including what changed and when.
- Preset rules: account takeover, credential stuffing, bot detection, multi-accounting and promo abuse ship ready to use.
Requirements are modest. PHP 8.0 to 8.3, PostgreSQL 12 or later, Apache with mod_rewrite, and roughly 3 GB of storage per million events. A Docker Compose command, a Heroku button and a Composer package all work, and a cron entry every ten minutes handles background jobs. It suits SaaS platforms, marketplaces, internal and legacy apps, and air-gapped deployments.
