IT security is crucial to success in today’s economy. A data breach can cost you time, money, and your customers’ trust. Yet, due to a lack of funding, time, and expertise, most small- and medium-sized businesses (SMEs) are unprepared to deal with basic cyber threats. As a result, most victims of data breaches are small businesses.

We understand — and we want to help. ProtonMail is a pioneer in encrypted email, and we have worked with thousands of businesses of all sizes to help them secure their email communications. This experience gave us insight into the unique IT security requirements and constraints that SMEs face.

In the past, we have helped small business owners avoid phishing attacks and train their staff on IT security basics. But given the depth of expertise our team has, we felt we could do more. Our internal security team is responsible for securing the data and emails of thousands of businesses of all sizes. We decided to pass our knowledge on to other businesses and increase online security for all.

So, our IT security team has created a simple, actionable guide for business owners.

If you’re a business owner or manager who needs help with IT security, this guide gives you straightforward advice from the staff of a recognized leader in cybersecurity.
