10 simple steps to protect your company without investing in expensive technology

If you run a small or medium-sized business, you have probably thought that protecting it from cyberattacks requires thousands of euros, sophisticated tools or a specialised technical team. The good news is that it doesn't have to be that way. Many of the most effective cybersecurity measures do not require large investments. What they do need is awareness, organisation and action.

In this article we share a basic, practical checklist you can start applying today, without spending a single euro or with minimal resources. Because your business's security is not a luxury; it is an achievable priority.

A basic cybersecurity checklist for your company (without spending thousands of euros)

1. Use strong passwords

Weak or reused passwords are one of the most common entry points for cybercriminals. If an attacker obtains a single password, they could access several of your company's critical accounts. That is why every password must be unique, long and complex. A password manager such as Bitwarden (free) lets you generate secure passwords and store them encrypted, without having to memorise them all. Just install the app or browser extension, create a secure account and start storing your credentials.

2. Turn on two-step verification (2FA)

Even if a cybercriminal gets your password, two-step authentication stops them from accessing your accounts without a second verification code. This drastically reduces the risk of unauthorised access. It is especially important for email, social media and business management platforms. You can easily enable it in each account's security settings, using apps such as Google Authenticator or Authy, which generate temporary codes on your phone.

3. Always keep your operating system and software up to date

Updates don't just bring new features: they fix security flaws that attackers can exploit. When you postpone an update, you leave open a door that criminals already know about. To avoid this, turn on automatic updates in your operating system (Windows, macOS or Linux) and also in programs such as browsers and office suites. It only takes a few minutes and protects you from multiple threats.

4. Use a reliable, free antivirus

Even if you don't see it, your computer is exposed every day to risks such as viruses, trojans or ransomware. A good antivirus detects and blocks these threats before they cause damage. If your budget is limited, Microsoft Defender (already included in Windows) is a reliable free option. Just make sure it is enabled, up to date and running automatic scans regularly. You can also add weekly manual scans for extra peace of mind.

5. Back up regularly

Attacks such as ransomware, human error or technical failures can make you lose important files. Having a backup gives you a second chance. Ideally, make monthly backups (or weekly ones if you handle critical information). You can use cloud services such as Google Drive or Dropbox; you can also simply save your files to a secure external drive, although this is not the best option because of the physical risks these devices are exposed to. Remember to keep at least one copy outside the office.

6. Learn to spot suspicious emails (phishing)

Many attacks start with a simple email that looks legitimate but aims to steal your credentials or install malware. If you or someone on your team falls into the trap, the damage can be huge. That is why it is crucial to get into the habit of being suspicious of urgent messages, messages with spelling mistakes or messages asking for sensitive data. A good practice is never to click directly on doubtful links. If in doubt, check with someone on the team before acting.

7. Remove software you no longer use

Every program you install is a potential entry point for attackers, especially if it is no longer updated. Keeping only what you need reduces the "attack surface" and improves your devices' performance. Do a monthly review and uninstall what you don't use from your operating system's control panel. When it comes to security, less is more.

8. Encrypt your devices if you handle sensitive information

If your laptop is lost or stolen, anyone could access the files if they are not encrypted. Encryption protects the information even if the device falls into the wrong hands. On Windows (Pro edition) you can enable BitLocker, and on macOS you can use FileVault. Once enabled, all the disk's contents are protected by a password.

9. Review who has access to what

Not everyone in your company needs access to every document or system. The more open access you have, the easier it is for a compromised account to cause damage. Apply the principle of "least privilege": each person should have only the permissions they need to do their job. You can review and adjust this in your platforms' settings (Google Workspace, Dropbox, etc.).

10. Create an internal channel for security alerts

Fast communication can prevent many incidents. If someone spots a suspicious email or notices something odd on their computer, they must be able to warn everyone else immediately. Creating a WhatsApp group or a Teams or Slack channel just for security alerts is a simple but powerful solution. It also helps build a security culture within your company.

Bonus tip:

Get your team together once a month to talk about security for 15 minutes.

Cybersecurity is not just technology: it is culture. And culture is built by talking, sharing and learning together. A short monthly meeting can make the difference between a team that reacts with fear and one that prevents with confidence. You don't need to be an expert: it is enough to review a recent situation together (such as a phishing attempt) or reinforce one of the points on the checklist. If you do this consistently, you will be planting a culture of prevention in your company.

Most of the digital threats SMEs face do not require complex solutions to mitigate. They start with good decisions and simple actions like the ones you have just read.

With this checklist you are already taking a firm step towards a more secure company, without large investments or advanced technical knowledge. What matters is not having everything perfect from the start, but beginning, little by little, to reduce the most common risks.

Remember: cybersecurity is not a luxury… it is a responsibility you can take on with the tools you already have at hand.
