SMB Cybersecurity Report 2026

1 in 4 small businesses hacked despite cybersecurity measures

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.

Hackers breached one in four SMBs last year, even though virtually all the victims had taken precautions.

SMBs spend as much recovering from cyberattacks as they do trying to prevent them.

Human error, inconsistent security policies, and lack of data control are to blame.

The security status quo is failing SMBs

Many of the defenses in place are designed for ideal behavior, not for how people actually work.

57%

of breached SMBs lost $10,000–$100,000

39%

of incidents stemmed from human error

28%

don’t feel in control of how cloud providers handle their data

48%

don't have a password manager in place at their organization

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.

Anxiety over data in the cloud

Almost all the SMBs (86%) we surveyed rely on cloud service providers like Google or Microsoft. But as many as 28% of that group say they don’t feel in control of how their data is handled, or aren’t sure. When your provider handles your encryption keys and collects your data, an attack on third-party companies can affect your business.

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:

38% were disrupted

It was worst in the the US, where more than half of the SMBs hit by a cyberattack (51%) said they suffered downtime or operational disruption, halting business.

35% faced legal/IT costs

Legal or IT remediation expenses affected all markets, but Germany’s rate was highest (38%), likely driven by more rigorous data protection requirements.

46% suffered data loss

Among those hit by a breach, Brazilian businesses outpaced the average for data loss, with more than half (53%) reporting that outcome.

24% received penalties

Japanese firms, which were the least impacted by cyberattacks, were also the least likely to have paid fines or regulatory penalties (14%).

How did the breach affect your business?

The survey suggests that well over 1 million small- and medium-sized businesses in the markets we studied suffered a cyberattack last year. Nearly all of them faced costs and operational disruptions.

Stay one step ahead of the hackers

In compiling the SMB Cybersecurity Report 2026, Proton surveyed 3,000 business and IT leaders of companies under 250 employees across the US, UK, France, Germany, Brazil, and Japan.
