As answered by people managing EATHERIA and CodePen.
EATHERIA's answer
Development teams and AppSec engineers at startups and mid-size companies who need enterprise-grade security scanning without enterprise pricing — as well as individual developers and freelancers who want to ship secure code. The bilingual interface also makes it a natural fit for LATAM and Spanish-speaking engineering teams.
EATHERIA's answer
EATHERIA combines SAST, DAST and SCA in one platform and then uses AI to validate every finding — so teams spend time fixing real vulnerabilities instead of triaging false positives. It delivers enterprise-grade AppSec (OWASP Top 10, CWE, PCI DSS, NIST mapping, SBOM export) at a fraction of the cost of legacy tools, with a free scan to get started in minutes.
EATHERIA's answer
Three reasons: (1) AI validation dramatically cuts false positives — the #1 complaint with Fortify, Checkmarx and Veracode. (2) Pricing starts at $35/mo with a free scan, versus enterprise contracts that start in the thousands. (3) It's built for modern workflows: CI/CD ready with GitHub Actions, SBOM export, and a bilingual EN/ES interface out of the box.
EATHERIA's answer
EATHERIA was born from the frustration of working with legacy AppSec tools: expensive licenses, slow onboarding and endless false-positive triage. We set out to build the platform we wanted — fast to start, AI-validated findings you can trust, and priced so any team can afford real application security.
EATHERIA's answer
The platform is built with Next.js and TypeScript, backed by PostgreSQL and Redis, containerized with Docker, and integrates AI models for finding validation. Security scanning covers static analysis (SAST), dynamic testing (DAST) and software composition analysis (SCA), with Stripe powering billing and GitHub Actions for CI/CD integration.
