About
The home of Ovvlo
A focused brand hub for products, open-source macOS tools, and client work — security, software lifecycle, education, and infrastructure.
From Sendtry → Ovvlo
Why a brand hub
Sendtry started as its own surface. As more products landed — SharePassword for secrets, SoloLeveling for interview prep, native macOS tools for infrastructure — the brand needed a home that isn’t tied to a single product name.
ovvlo.com is that home: product family, open source, demos, and security posture. Product domains stay product-owned. The hub stays clear.

Pillars
What we cover
Security & Defense
Cloud posture, packages & CVEs, prompt injection, API risk, secret hygiene — systems we keep hardening in the agent era.
Software Lifecycle
From client brief to shipped work — requirements, approvals, delivery, and issue flow.
Education
Interview prep and skill systems with deadlines, evidence, and deliberate practice.
Infrastructure
Native tools for ports, processes, diagrams — systems that stay legible.
