It’s always a good time to assess your security. We’ve shared some of our most important cybersecurity guides to help.
At Proton, your security is our top priority. We believe your data belongs to you and you alone, which is why we protect it with end-to-end encryption(nova janela) and zero-access encryption(nova janela). Unfortunately, your security is not simply an on/off switch, nor is it something you can outsource to a single tool or service. Rather, it requires your input and attention. Your cybersecurity relies upon your behaviors, systems, and tools, and it’s only as strong as your weakest link.
For example, if you use Proton Mail, set strong passwords, and use two-factor authentication but fall for repeated phishing attacks (emails that pretend to be from a trusted source to get you to share information), you’ll put your information at risk. That’s why we created these guides, so you can protect yourself and stay in control of your information.
To help you cover your cybersecurity bases, we’ve compiled several of our guides so you can follow them and keep yourself safe.
- How to avoid being phished
- How to make a strong password
- How to use two-factor authentication
- How to keep your device secure
- How to prevent cyberstalking and social engineering
- How to choose a browser that protects your privacy
- How to recover from a data breach
At Proton, we’re building a better internet where privacy is the default. To do this, we encrypt as much of your data as possible, making it more secure even if the worst happens. If you want an internet that focuses on protecting your data rather than collecting it, join us!
How to avoid being phished
Phishing and its many variants affected more than 320,000 victims in 2021 alone(nova janela), making it the most common cyberattack. A phishing email typically appears as though it’s from an authority, such as a bank, and tries to instill a sense of urgency to make you act before you can investigate it. Its ultimate goal is to get you to share sensitive information or to click a link that will deliver malicious software onto your device.
While some can be quite convincing, most phishing operations send mass emails, hoping to catch someone while they’re distracted. You can usually spot a phishing attempt if you just remember to take a moment and look closer. You should investigate any email that:
- Is from an odd email address or one that you don’t recognize
- Is unexpected or a surprise
- Is poorly written or full of grammatical errors
- Claims something is urgent and can only be fixed by clicking a link contained in the message
If you’re uncertain whether an email is a phishing attempt, you can always try to contact the sender by calling or texting them at a number you know is real. For example, if you’re suspicious an email from a bank could be fake, look up its phone number on its website. Do not click a link or download an attachment until you’re certain you’re not dealing with a phishing attempt.

How to make a strong password
Your password is the first line of defense for your online accounts, which is why it’s so critical you put more thought into it than just using “Password” or “123456789”.
The easiest way to make sure all your accounts have strong, unique passwords is to use a secure password manager to create and save your passwords for you. Then, all you need to remember is a single strong passphrase(nova janela) for your password manager.
Your password is only the first half of the equation, however. Since usernames are often your email address — a key piece of your online identity — it’s important to keep this information private if possible. Proton Pass lets you generate email aliases(nova janela) to keep your real email address private.

How to use two-factor authentication
If your password is your account’s first line of defense, two-factor authentication (2FA) is the backup that keeps you safe if your password is cracked. Most 2FA methods require you to enter a one-time passcode from an authenticator app on your phone, but there are also hardware security keys that you simply need to tap. You should avoid 2FA that relies upon SMS, as this has proven less secure. (Proton Pass includes built-in 2FA so you can autofill your username and password, as well as your 2FA passcode.)

How to keep your device secure
Fortunately, this is a relatively easy one. There are four things you can do that will protect you from the vast majority of threats that could compromise your device’s security:
- Always keep your device’s operating system, apps, and other software up to date.
- Secure your device with a strong password.
- Do not give anyone physical access to your device unless you trust them.
- Turn Bluetooth and AirDrop off if you’re not actively using them.
Developers release updates in response to known security vulnerabilities. If you use outdated software, you’re leaving vulnerabilities in place that malicious actors are actively exploiting. The best way to keep your software up to date is to turn on the auto-update option everywhere you can.
Preventing physical access to your device and securing it with a strong password are common-sense measures. If an attacker gets hold of your device, it can be very difficult to make sure that they did not compromise it.
Bluetooth and AirDrop are convenient features, but known attacks, such as BlueBorne (nova janela)and BrakTooth(nova janela), can take advantage of them. By keeping Bluetooth off, except when you’re actively using it, you reduce the chance that your device could be affected by these exploits.
How to prevent cyberstalking and social engineering
The information you freely share with the internet can often be used by malicious actors. This is because social media posts can often contain a lot of information that you might not consider, including:
- Your location
- Your appearance
- Your friends and acquaintances, and more
Consider fitness apps. In 2018, soldiers using Strava accidentally revealed their identities and locations(nova janela) on a high-security military base. Similarly, if you constantly post photos of your trip on social media while you’re away on vacation, you let people — and burglars(nova janela) — know you’re not home.
If you use social media, you should consider adjusting the privacy settings for your preferred platform and think about what information your posts reveal — and what could be done with that information if it fell into the wrong hands.

How to choose a browser that protects your privacy
You might not normally consider your choice of browser as a cybersecurity decision. However, nearly everything you do online requires using a web browser, such as Google Chrome, Apple Safari, or Mozilla Firefox. This gives your browser access to nearly all of your browsing activity, as well as your IP address, location, device operating system, and more, making it worth your while to consider which browser you want to use.
Google Chrome, by far the world’s most popular browser, has been custom-built by Google to sweep up as much data as possible(nova janela). Even Chrome’s “privacy features”(nova janela) are actually designed to facilitate Google’s surveillance of your browsing activity. To protect your data, you should use a privacy-focused browser like Mozilla Firefox, the Tor Browser, or Brave.

How to recover from a data breach
While preventing a data breach or hack is always preferable to recovering from one, sometimes a cybersecurity failure is not your fault. Unfortunately, major data breaches by corporations(nova janela) continue to happen, sometimes affecting hundreds of millions of people(nova janela). When this happens, you’ll want to act quickly to make sure none of your information can be used to steal your identity or drain your bank accounts.
