Why email security is mission critical to FastMail

ecosystem showcase fastmail

According to the Verizon 2017 Data Breach Investigations Report, gaining access to a user’s personal or professional data through a malicious email is a cyber criminal’s weapon of choice. While many users might consider that there is nothing worth taking inside their inbox, they are most likely overlooking how connected their email is to other digital accounts. Stolen email credentials can unlock other accounts, and reusing passwords across multiple logins makes that risk even greater. In other words, email security is critical.

Phishing attacks are amongst the most prevalent of threats to email, and typically use some pretext to convince you to reveal your credentials directly or to visit a fake login page that prompts you to do the same. Phishing alone is responsible for huge monetary losses each year, and sadly still affects around 1 in 14 users. There are a number of precautions you could take to avoid being phished, starting with using an email platform that enables two-factor authentication and an unphishable YubiKey.

Our trusted tech partner FastMail has made security a core feature of their email platform. FastMail provides an extensive range of encryption practices to keep your data safe from prying eyes, including full support for two-factor authentication. With FIDO U2F and YubiKey One Time Password (OTP) integrated into their services, FastMail recommends setting up YubiKey 2FA for the peace of mind that comes with additional security.

“FastMail has built its reputation by offering highly secure login mechanisms. The YubiKey provides a simple yet robust solution, ensuring that people can log in and access their email on any machine without the worry of their authentication details being stolen,” says FastMail co-founder Rob Mueller.

FastMail has been hosting email for companies and discerning individuals around the world since 1999, making it one of the longest operating email services on the web. Trusted by over 150,000 users in 150 countries today, FastMail is an employee-owned, independent company headquartered in Melbourne, Australia, and runs a portfolio of communication and collaboration services.

Topicbox, FastMail’s latest group email offering, is also now YubiKey-enabled. Topicbox increases productivity by providing unlimited groups to keep conversations organized, customized email delivery options to minimize distractions, and searchable team history for better onboarding.

“Protecting your information is critical for every organization, so YubiKey support was natural to build into Topicbox from the start,” says FastMail’s COO Helen Horstmann-Allen. “Topicbox makes communicating with your teams faster and easier, and Yubico does the same for your team’s security.”

You can also try Topicbox free for one month by visiting topicbox.com.

Yubico is proud to highlight FastMail as part of an ongoing Works With Yubikey program. Visit our Works With YubiKey catalog page to learn more about all the products and services that support YubiKeys.
