Ten rules of on-line security that will protect you

Use a VPN

A VPN (Virtual Private Network) encrypts your internet traffic and protects it from unauthorized access. While traveling and often connecting to unsecured Wi-Fi networks, a VPN is a reliable way to safeguard sensitive data. It helps hide your location and protects your passwords and login credentials. Although it may slightly slow down your connection, the extra security is worth it.

Avoid public Wi-Fi networks

Hotel, airport, or café Wi-Fi might seem convenient, but it's often poorly secured. An attacker on the same network can monitor your activity – from checking your email to entering credit card details. If you must use a public network, always connect via a VPN and never access company systems through it.

Enable two-factor authentication (2FA)

Two-factor authentication adds an extra layer of security, such as a code sent via SMS or generated in an authentication app. While traveling, when there's a risk of device loss or account compromise, 2FA is an effective way to block unauthorized access to sensitive information.

Avoid installing unknown apps

Free Wi-Fi in exchange for downloading an app? A discount for a game you’ve never heard of? What seems like a good deal could actually be a security threat. Unknown apps may gain access to your contacts, photos, or location – and in some cases even your online banking. Only install trusted apps from official stores (Google Play, App Store) and always check what permissions they request. No, a dolphin tour booking app really doesn’t need permission to make phone calls.

Lost your phone? Here’s what to do

Your phone today holds your entire digital life – banking, photos, login access. Before you travel, make sure backup is enabled, “Find my device” is active, and you have the option to erase the phone remotely. If your phone is lost, act fast – block your SIM card, log the device out of your accounts, and notify your mobile provider and bank.

Visit only trusted websites and double-check URLs

Attackers often create fake websites that mimic well-known services like Booking, Ryanair, or Zalando. Travelers are a common target of these scams. Before booking flights, accommodation, or purchasing a highway vignette, always double-check the URL. Even a small change in letters (e.g., “b00king.com” instead of “booking.com”) can signal a phishing attempt.

Working while traveling? Handle your company laptop with extra care

A company laptop is not a regular device – it often contains sensitive data that should never fall into the wrong hands. Never connect it to public Wi-Fi, avoid entering credentials on untrusted websites, and don’t leave it unattended. If possible, use your own mobile hotspot, which is more secure than open networks.

Use strong and unique passwords

Using the same password for all accounts is like having one key for every lock – and if someone gets it, they get access to everything. Create strong, unique passwords for each service and store them securely in a password manager. You don’t need to memorize them – what matters is their security. Ideally, combine strong passwords with two-factor authentication (2FA) and a trusted password manager.

Keep your devices up to date

Make sure your operating system, apps, and security software are all up to date. Regular updates often fix known vulnerabilities that attackers actively exploit. Enable automatic updates on laptops and smartphones – including antivirus software, browsers, and other frequently used tools. Delaying updates exposes you to unnecessary risks, whether you're at home or on the go.

Share with caution

Social media posts may seem harmless – a few beach photos, tagging your location, or a caption like “finally on vacation!”. But in reality, you might be unintentionally announcing that your home is empty. Try sharing photos and experiences after you return. Even while traveling, be mindful of what and when you post – especially details about your current location or upcoming plans.
