Proton: SMB Cybersecurity Report 2026

Proton: SMB Cybersecurity Report 2026


This report from Proton surveyed business leaders around the world to identify their principal cyber security issues. It looks at the most common threats being faced, and provides solutions for addressing each issue.

Businesses are trying to guard against breaches, but their efforts fail under real-world conditions.
To understand why, Proton asked 3,000 founders, executives, and IT leaders across three continents about their cybersecurity practices. The insights we gained will help you protect your business.

Attacks cost small businesses dearly
The small businesses that reported breaches last year were spending on their security, but their defenses failed. The attacks ended up costing them about as much money as they spent on protection. About 57% reported losses between $10,000 and $100,000.

Taking steps in the right direction
Security wasn’t informal or ad hoc. Far from the cliché of the clueless small business, these SMBs had training programs, recurring audits, and tools in place before the breach. But security solutions become ineffective when they’re optional, unevenly enforced, or easy to bypass.

Training won’t catch every slip
In fact, 39% of businesses report experiencing a cybersecurity incident caused by human error. Strong security requires both training and secure business tools that enable security hygiene by default.

Investing in tools isn’t enough
Password sharing is a clear example. Even respondents that have a password manager on their tech stack still share credentials via email, messaging apps, shared documents, conversations, or in writing.

Not all the losses were financial
Once attackers got in, the consequences spread far beyond money. Cyberattacks disrupted operations, exposed data, and undermined trust. Damage looked different by country:
