THE TRUSTED MIDDLE LAYER

Ethical Vulnerability Brokerage Powered by Nexus AI.

Stario is a secure interface between security findings and corporate remediation, both by privately brokering lawful vulnerabilities for researchers and by enabling companies, via Talaria Labs, to commission private targeted scans that go beyond passive bug reporting to active threat elimination.

Researchers authorize Stario to represent and license their findings. Only verified asset owners can unlock full reports and PoCs.

How Stario Works

A lawful, contract-backed bridge between researchers & organizations.

Stario represents researchers, not exploits. Every workflow is aligned with public VDP/bug bounty policies and asset ownership verification.

Step 1

Researchers Onboard & Assign

Researchers sign a brokerage agreement and submit only lawful, in-scope findings that adhere to the organization's Bug Bounty policy. They authorize Stario to present, and license their work.
Step 2

Nexus AI Scores & Prices

Nexus AI checks severity, impact, scope, novelty and public policies, benchmarking against historical payouts and similar reports to propose a fair payout band for both sides.
Step 3

Vendors Unlock & Remediate

Only verified asset owners see redacted listings mapped to their domains. A single unlock action triggers escrow, releases full PoC under contract, and keeps a clean audit trail.
For Researchers

You find real bugs. Stario gets you real payouts.

Your job is finding bugs. Our job is getting you paid for them. We'll present your research, use our fine-tuned Nexus AI to set a fair price, and take care of all the back-and-forth

Why researchers work with Stario

  • AI-informed payout bands based on real-world bounties, not arbitrary offers.
  • Escrow or program-aligned flows before full PoC release.
  • No sales to unknown third parties; only the impacted organization can unlock.
  • Focus on finding bugs. With our experience, we'll make sure your payout is handled smoothly and without any stress.
If an offer comes in below Nexus AI's fair band, you see it—and decide.

Go Beyond the Public Queue

Stario provides a private, managed bridge to top researchers, acting as an intelligent intake layer where you only see reports that are already triaged, scored, priced, and confirmed to match your assets and policies—letting you acquire them before they enter your public queue.

How Your Team Benefits

  • Our robust verification process (DNS/email/legal) ensures you only see findings that belong to your organization.
  • Your private dashboard shows redacted, high-level previews of pending reports: asset family, severity, and the Nexus AI payout band.
  • Stario complements your existing security workflow, whether you use a public platform or a 'security@' email. No disruption, just added capability.
  • Purchase the full rights to the report and PoC with a single click. This provides a clean, contractual transfer and a full audit trail, letting your team remediate immediately.

A Framework Built for Trust & Compliance

We designed Stario on a foundation of legal clarity to eliminate the chaos and ambiguity of vulnerability disclosure. Every report, every payout, and every interaction is governed by explicit, contract-backed agreements that protect both researchers and your company.

  • Researchers legally authorize us to represent their findings, confirming lawful discovery and adherence to your policies.
  • All flows are underpinned by clear assignment or licensing language. When you acquire a report, you get a clean, documented transfer of rights, giving your legal and compliance teams a fully auditable trail.
  • We enforce a "one-to-one" model. Only the verified asset owner is ever given the option to unlock a report.
