Daily Digital Hygiene: 7 Essential Practices for Every Employee

You wash your hands several times a day, you lock your car when you leave, you turn off the lights when you leave the office. These actions have become so ingrained that you don't even notice them anymore. Digital hygiene is exactly the same thing: a series of simple habits that, once adopted, protect your company without you having to think about it constantly.

In a Swiss SME, where each employee juggles multiple responsibilities and where there isn't always a dedicated IT team, these daily micro-habits become even more important. A single oversight, a single click on the wrong link, and the entire organization can be paralyzed by a cybersecurity incident. The good news? These actions only take a few seconds a day and don't require any special technical skills.

Here are the seven essential habits that every employee should integrate into their professional life, whether you work in human resources, accounting, customer service, or any other department.

1. Always lock your session when you step away

How many times have you left your desk to get a coffee, chat with a colleague, or go to a meeting, leaving your computer unlocked and your session open? It seems harmless, especially in a small structure where everyone knows and trusts each other. And yet, it's one of the most common entry points for security problems.

An unlocked computer is like leaving the keys in the door of your office. Anyone can access your emails, view confidential documents, or even send messages in your name. In an SME environment, where visitors, interns, external service providers, and clients regularly pass through, the risk is significant. It only takes a few seconds for a malicious person to copy sensitive data or modify an important file.

The habit to adopt is simple: Windows + L on PC, or Command + Control + Q on Mac. These keyboard shortcuts instantly lock your session. If you're the type to forget, configure your computer to lock automatically after a few minutes of inactivity. This is a measure you can ask your IT department or external service provider to implement for all company workstations.

2. Verify the sender before opening an email or attachment

You receive an email that appears to be from your bank, your usual supplier, or even a colleague. The message asks you to click on a link or open an attachment. You're in a hurry, you trust the professional appearance of the message, and you click without thinking. This is exactly what cybercriminals are looking for: to take advantage of our trust and routine to trap us.

Fraudulent emails (also known as phishing) have become extremely sophisticated. They perfectly mimic official communications, use the correct logos, and adopt the appropriate tone. The difference often lies in the details: a slightly different sender address (for example, "accounting@your-company.ch" instead of "accounting@yourcompany.ch"), a subtle spelling mistake, or an unusual sense of urgency.

Get into the habit of always verifying the complete email address of the sender, not just the displayed name. Hover your mouse over the links without clicking to see the real URL. If something seems strange, even slightly, call the person or organization directly to verify. This is especially important for emails containing payment requests, changes to bank details, or confidential information. In Switzerland, with the requirements of the nLPD (new data protection law), a data leak due to phishing can have serious legal consequences for your company.

To train yourself to recognize these attempts, many Swiss SMEs use tools like PhishTrainer, which simulate phishing attacks in a controlled environment to develop your reflexes.

3. Use strong, unique passwords for each service

Many employees still use the same password for all their professional accounts, or choose easy-to-remember passwords like "Company2024!" or "Welcome123". It's understandable: remembering dozens of different passwords seems impossible. But using the same password everywhere is like using the same key for your house, your car, your office, and your safe. If someone finds that key, they have access to everything.

Cybercriminals know this well. When a website is hacked and its password database is stolen (which happens regularly), they test these same email/password combinations on other services. If you use the same password for your professional email, your access to the CRM, and your online bank account, a single theft is enough to compromise everything.

The simplest and most effective solution is to use a password manager. These tools automatically generate and store complex and unique passwords for each service. You only have one master password to remember, the one that unlocks the manager. Swiss solutions like Proton Pass or tools integrated into modern browsers make this practice accessible even for the least technical among you.

Don't forget to enable two-factor authentication (2FA) wherever possible, especially for your emails and your access to the company's critical systems. It's like adding a second lock to your door: even if someone gets your password, they won't be able to access the account without the second authentication factor.

4. Update your tools and applications regularly

The update notifications that appear on your screen are often perceived as annoying interruptions. You're in the middle of work, focused on an urgent file, and suddenly your computer asks you to restart to install updates. The temptation is great to click on "Remind me later" and postpone indefinitely. Yet this is one of the most costly mistakes in terms of security.

Updates are not only used to add new features or improve the interface. They also fix security vulnerabilities discovered in the software. When a company like Microsoft, Apple, or Adobe releases a security update, it's because they have identified a vulnerability that hackers could exploit. And they don't waste any time: as soon as a flaw is publicly known, they test it massively on all computers that have not yet been updated.

In an SME, a single unupdated computer can be enough for a ransomware to infect the entire company network. The consequences can be dramatic: encrypted files, paralyzed activity for days, data loss, ransom demand. And all of this could have been avoided with a simple update that takes ten minutes.

The habit to take: install updates as soon as they are offered to you, or schedule them to install automatically outside of your working hours. This applies to your operating system, but also to all your software: web browser, office suite, business applications, antivirus. If your company uses a centralized update management solution, follow the policies put in place by your IT department.

5. Regularly clean your downloads folder

Your downloads folder probably looks like a cluttered attic: files you opened once months ago, documents you don't even remember the origin of, ZIP archives with cryptic names. This mess is not just a matter of organization, it's also a security risk.

Every file you download from the Internet is a potential entry point for malware. A PDF received by email, an invoice downloaded from a website, an Excel file sent by a business partner: all can contain malicious code. As long as these files remain in your downloads folder, they represent a risk, especially if you no longer remember where they came from and you accidentally open them later.

Get into the habit of sorting your downloads folder at least once a week. Move important files to their final location (project, client folder, documentation), and delete anything you no longer need. It's also an opportunity to check that you haven't kept documents containing sensitive data (personal information of clients, financial data, HR documents) in a temporary and unsecured location.

For Swiss SMEs that regularly handle personal data, this practice fits perfectly with compliance with the nLPD, which requires data to be kept only for the time strictly necessary and under appropriate security conditions.

6. Log out of online services after use

Staying permanently connected to all your professional tools seems practical. You open your browser in the morning and all your services are already accessible: email, CRM, accounting, collaborative tools. No need to log in each time, everything is just a click away. It's comfortable, but it's also dangerous.

If you stay logged in and someone accesses your computer while you're away (a colleague who borrows your workstation to print a document, a visitor who is left alone in your office for a few moments), that person immediately has access to all these services. They can view your emails, modify data in your CRM, access confidential information, all under your identity.

The risk is even greater if you use a shared computer or if you occasionally connect from a workstation that is not yours. In these situations, never check the "Stay logged in" or "Remember me" box, and remember to explicitly log out of each service before leaving the workstation. On your own computer, log out at least from the most sensitive services at the end of the day.

This habit is particularly important for your online payment tools, your bank access, and all services containing personal or financial data. It's also a good time to close all unnecessary tabs in your browser: the fewer active services you have at the same time, the fewer opportunities you create for a compromise.

7. Regularly back up your work and check the backups

Backup is probably the most neglected digital hygiene practice. Many employees assume that "it only happens to others" or trust automatic systems without ever checking that they actually work. Until the day a computer breaks down, a file is accidentally deleted, or a ransomware encrypts all the company's data.

In an SME, data loss can have dramatic consequences. A client file that disappears is a compromised business relationship. Lost accounting data means hours of rework and potentially problems with the tax authorities. A project in progress erased is a delivery delay and a tarnished reputation. For some companies, the loss of critical data can even jeopardize the survival of the business.

The habit to adopt depends on your work environment. If your company uses collaborative tools online (Microsoft 365, Google Workspace, or Swiss solutions like kDrive from Infomaniak), your documents are normally backed up automatically in the cloud. But this does not exempt you from regularly checking that your important files are properly synchronized and that you can access them from different devices.

If you work mainly on local files stored on your computer, make sure that an automatic backup is configured. Many companies use the 3-2-1 rule: three copies of your data, on two different media, including one offsite copy (cloud or remote server). Solutions like Swiss Backup from Infomaniak make it easy to meet this requirement while keeping the data in Switzerland.

But be careful: having a backup is not enough. You must also regularly test that you can restore the data if needed. Take a few minutes each month to check that a test file can be recovered from your backups. This is the only way to be sure that your safety net is really operational.

Conclusion: small actions, big effects

Digital hygiene is nothing complicated or technical. These are simple habits, similar to those you already have in your daily life. You check that your door is closed before leaving, you look both ways before crossing the street, you wash your hands before eating. These actions don't require any conscious effort because they have become automatic.

The seven practices we have just explored work in exactly the same way. At first, you will have to think about it consciously. You may place a post-it on your screen to remind you to lock your session, or you may schedule a weekly alarm to clean your downloads. But after a few weeks, these actions will become natural. You will automatically lock your computer when you get up, you will instinctively check the sender of an email before clicking, you will install updates without even thinking about it.

For a Swiss SME, where every employee counts and where IT resources are often limited, these collective micro-habits create a real security culture. You don't need an IT team of fifteen people or security systems worth hundreds of thousands of francs. You need each member of the team to adopt these few daily habits.
