Know what you're taking on

An acquisition brings domains, apps, and infrastructure that nobody on your team has tested. Hadrian maps the acquired company's external attack surface so exposures are known before its systems connect to yours.

Attribute every asset to the right company

In a large group, the hard part is knowing which domains belong to which company, and which don't belong to you at all. Hadrian attributes each asset to the right subsidiary or business unit, which cuts the clean-up work that comes from tools claiming assets you don't own.

Clean up legacy infrastructure

Mergers leave behind old MSP-managed servers and forgotten environments. Hadrian finds and tests them alongside the rest of your estate, giving you one view across the group while you consolidate.

Frequently Asked
Questions

Learn how Hadrian helps security teams find, verify, and fix what attackers actually exploit.

What does Hadrian do?

Hadrian is an agentic AI offensive security platform that continuously discovers your external attack surface and tests it for exploitable exposures. The platform deploys in minutes, operates autonomously, and delivers validated findings with reproduction steps and execution evidence. No agents to install, no infrastructure to manage.

Can Hadrian assess a company before the deal closes?

Hadrian can map a company's internet-facing assets using passive discovery. Active testing needs authorization from the asset owner, so it usually starts once the deal closes.

How does Hadrian tell which assets belong to which subsidiary?

Hadrian uses ownership signals from DNS, certificates, and registration records, and your team can confirm or correct attribution in the platform.

Can each subsidiary manage its own findings?

Yes. Role-based access lets each subsidiary or business unit see and act on its own assets, while the group security team keeps the full view.
