Questions & Answers

As answered by people managing Nessus and Orb44.

What makes your product unique?

Orb44's answer:

Orb44 stands out by combining external AI-driven web perimeter scanning with an internal "Watch Satellite" for VPS monitoring in one platform. Unlike traditional enterprise scanners that require complex setups, Orb44 is fully autonomous, requires no root access, leaves zero logs, and uses AI to provide clear, step-by-step remediation instructions rather than just a list of generic alerts.

Why should a person choose your product over its competitors?

Orb44's answer:

Competitors require steep learning curves, complex setups, and massive enterprise budgets. Orb44 is built for creators, founders, and agencies who need immediate results without the friction or the premium price tag. Starting with a generous free tier and affordable premium plans, you get autonomous AI pentesting, actionable insights instead of generic alerts, and human expert support when you need it.

How would you describe the primary audience of your product?

Orb44's answer:

Orb44 is built for creators, indie developers, "vibe coders", business owners, and growing agencies. Our primary audience includes anyone who manages digital infrastructure but doesn't have the massive budget or specialized in-house expertise to use complex enterprise security tools. We cater to builders and entrepreneurs who need fast, affordable, and actionable security insights, backed by human expert support to actually fix the vulnerabilities.

What's the story behind your product?

Orb44's answer:

Our team's core background is originally in Artificial Intelligence development, not purely cybersecurity. The idea for Orb44 actually came by accident. We were pulled in to help resolve a complex security issue, and while applying our AI expertise to analyze the problem, we discovered a highly efficient, automated method for finding web vulnerabilities. The results were so fast and accurate that we had a "lightbulb" moment. We realized this solution was too valuable to keep as an internal tool and decided to package it into an accessible, standalone product to help other founders and developers secure their infrastructure. That's how Orb44 was born.
