For construction & engineering companies

Stop a fake bank account number from ending a project's budget

Every new subcontractor and materials supplier is a new, unverified email relationship — exactly where invoice fraud does the most damage. Adlerwacht closes that gap without an IT rollout.

Built for how construction actually pays people

If your company brings on a new subcontractor, materials supplier, or trade partner for nearly every project — and pays them by wire, often for the first time, based on nothing but an email invoice — you're the company this was built for. No dedicated security team required, no changes to how your office already sends and receives email.

What it protects, specifically

Construction and engineering firms are targeted by exactly the pattern this product defends against: a supplier or subcontractor invoice, sent by email, with the bank account number quietly changed by whoever has broken into one side of the conversation.

  • The invoice or payment file itself — never sitting in an inbox in a form a hacked account could just open.
  • Delivery to the right person only — a passkey locks the file to the one person meant to receive it, even if their email is compromised afterward.
  • The content of the file — no swapped IBAN, no altered PDF, between the moment it's sent and the moment it's opened.

How this plays out on a real project

A general contractor brings on a new steel supplier for a project — the first invoice between the two companies, sent by email, for a large, one-time amount. Somewhere along the way, one side's mailbox has already been quietly broken into. The attacker waits for the real invoice, changes the bank account number, and lets it through. Nothing about the email looks wrong — same sender, same project reference, same amount — because it mostly is the real invoice, with one number changed. The payment goes out, and by the time anyone notices, it's gone.

Why construction companies choose Adlerwacht

Near-zero IT setup

Nothing to install, nothing to reconfigure in your existing email. Your office keeps sending invoices and payment files exactly as it does today.

End-to-end protection, not just a warning

Recipients unlock each file with a passkey — a fingerprint, face, or security key — never a password. For a brand-new subcontractor relationship, an SMS code confirmed by a real person at your company closes the one gap a first-time email contact would otherwise leave open.

Priced for a project-based business

Plans start at €79 a month, with SMS-verified identity checks included for every recipient, on every plan — no separate add-on to buy before a new subcontractor relationship is protected. Compare that against a single altered invoice on one project, and the math isn't close.
