Most Data Breaches Start with Stolen Passwords: Here’s How to Fix That

Somewhere in your organization right now, an employee is reusing a password they created in 2019. Another is sharing login credentials for a team account through a Slack DM. A third is storing client portal access in a browser’s built-in autofill, synced to a personal Google account your IT team does not control. None of these people are careless; they are simply doing what most workers do when their company has no password infrastructure.

According to Verizon’s 2024 Data Breach Investigations Report, stolen credentials were involved in roughly 80% of web application breaches and remain the single most common initial attack vector across all industries. The pattern is consistent year after year: an employee reuses a password, that password appears in a consumer data breach, an attacker tests it against the company’s systems, and the door opens. The breach rarely looks dramatic; it looks like a normal login.
The Fix: Beyond Strong Passwords
The fix is not telling people to choose better passwords. The fix is giving them a system that makes strong, unique credentials the default and removes the temptation to cut corners. That’s where business password managers come in—but they have a blind spot worth noting.
The Metadata Problem: Often Overlooked
When you evaluate a password manager, the first thing you check is encryption. Every serious product uses AES-256 and claims zero-knowledge architecture. However, encryption scope varies more than most buyers realize, and the difference has real consequences.
Standard password managers encrypt the contents of your vault: passwords, secure notes, and credit card numbers. But they often leave unprotected metadata surrounding those items—item titles, associated URLs, email addresses, and access timestamps. This metadata tells a story: it reveals which services your company uses, which employees access which accounts, and when. For an attacker who breaches the provider’s infrastructure (or a government that issues a subpoena), metadata can be nearly as valuable as the passwords themselves.
Proton Pass for Business: Closing the Gap
Proton Pass for Business, developed by Proton AG in Geneva (the team behind Proton Mail and Proton VPN), was built to close this gap. It encrypts everything: vault contents and all associated metadata, including item titles, URLs, email addresses, and timestamps. The encryption happens on your device before data reaches Proton’s servers, and Proton holds no decryption keys. Even if its servers were compromised tomorrow, attackers would get encrypted blobs with no way to determine what is inside or which websites your team uses.
