Hey dev.to community! 👋

Welcome to the Proton organisational blog on Dev.to. We thought this would be a good place to share the original research we undertake, to do with data privacy and cyber security.

Here's what our latest survey data reveals about the current state of cyber security for small and medium businesses from our SMB Cybersecurity Report.

The Big Picture

Proton surveyed 3,000 decision-makers at companies with fewer than 250 employees across six markets: the US, UK, Brazil, France, Germany, and Japan.

The headline finding is that nearly 1 in 4 SMBs fell victim to cyberattacks in the past 12 months, despite having security measures in place. Well over 1 million SMBs in these markets suffered a cyberattack last year.

Key Findings That Matter to Developers

1. Spending Does Not Equal Security
Many SMBs have implemented formal risk assessments, regular audits, multi-factor authentication, and password managers. Yet breaches still happen. The report challenges the "SMBs are unprepared" cliché; these businesses are investing in security, but defenses are failing under real-world conditions.

2. Human Error Cannot Be Patched
39% of incidents stemmed from human error. Even with password managers deployed, credentials still circulate via email, messaging apps, shared documents, and written notes.

The takeaway is that training alone is insufficient. Security tools need to enforce good hygiene by default.

3. Cloud Dependency Creates Blind Spots
86% of SMBs rely on cloud providers like Google or Microsoft. However, 28% of that group say they do not feel in control of how their data is handled or are unsure. When your provider handles encryption keys and collects your data, third-party attacks can cascade to your business.

4. Security Is Now a Competitive Advantage
A clear majority of SMBs say demonstrating strong data protection is critical for winning new business. Clients are actively asking about security practices.

The Cost of Breaches

The financial and operational impact of these breaches is substantial:

Financial Loss: 57% of breached SMBs lost between $10,000 and $100,000.
Operational Downtime: 38% overall (rising to 51% in the US) suffered downtime or disruption.
Data Loss: 46% overall (53% in Brazil) experienced data loss.
Remediation Costs: 35% faced legal or IT remediation expenses (38% in Germany).
Penalties: 24% received regulatory penalties.

There are notable regional patterns:

US: Highest operational disruption (51%).
Brazil: Highest data loss rate (53%).
Germany: Highest legal and IT costs (38%).
Japan: Least impacted overall.

What This Means for Developers

If you are building tools for SMBs, consider the following:

Assume human error will happen: Design systems that contain mistakes rather than trying to prevent them entirely.
Default to secure: Optional security features get bypassed; baked-in security gets used.
Be transparent about data handling: 28% of SMBs do not feel in control of their cloud data.
Make security a feature, not a checkbox: It is now a selling point for your customers' customers.

Discussion

Have you worked with SMBs on security implementations? What gaps have you noticed between "security on paper" and real-world effectiveness?
