A pentest describes the day it was run. Everything after it is assumption.
Radius exists so that the gap between "we tested" and "we know" closes every run, not once a year. Piscium is the company that builds and runs it.
The company
Piscium Security R.L. was founded in San José, Costa Rica, in 2026 by Emanuelle Jiménez, MSc, who is founder, CEO and the engineer who builds Radius end to end. It began as a university-linked spin-off, from one observation: a pentest describes the day it was run, and everything after it is assumption. Radius exists so that the gap between "we tested" and "we know" closes every run, not once a year. The company is one person today, bootstrapped, with the platform in production and real engagements on it. The name comes from Pisces, the constellation. The ocean-depth theme on this site is the same idea: charting what lies below the surface.

Every claim on this site is either documented product behaviour or labelled as demo data. RiverClear is a model built to show the product, not a customer. Piscium holds no certifications yet, and says so. A page that says “every claim is backed by evidence” cannot sit next to a figure nobody measured.
Start with one run.
A scoped run against the environment you authorize. It starts with a 30-minute call, and the rules of engagement are signed before anything else happens.
