Small and medium-sized enterprises (SMEs) are increasingly vulnerable to cyberattacks due to increasing digitalization and a lack of resources to implement advanced security solutions. Despite these limitations, there are accessible and effective strategies to improve information protection and minimize risks without requiring large investments.
Implement multi-factor authentication (MFA) on all accounts
Using multi-factor authentication (MFA) is one of the most effective ways to protect business accounts from unauthorized access. MFA adds an extra layer of security by requiring users to provide at least two forms of verification to access their accounts, such as a password and an authentication code generated on a mobile device. This measure drastically reduces the risk of stolen credentials being used to compromise critical systems.
Keep software and systems up to date
Software vulnerabilities are one of the main entry points for cybercriminals. Therefore, it is essential for SMEs to keep their software, including operating systems, applications, and security tools, up to date. Regularly applying security patches helps mitigate known threats and reduce exposure to exploit-based attacks.
To facilitate this task, it is recommended to enable automatic updates whenever possible and establish a periodic review policy to ensure that all devices and programs used in the company are protected with the latest versions.
Train staff in phishing detection
Phishing is one of the most common and effective attacks against SMEs. It involves tricking employees into revealing confidential information, such as login credentials or financial data, through fraudulent emails or fake websites.
To combat these types of threats, it's crucial to train employees to identify suspicious emails and teach them how to verify the authenticity of links and senders before clicking or providing sensitive information. There are free tools and online courses that can help educate staff on best practices for email and web browsing security.

Implement firewalls and antivirus software
Firewalls and antivirus software are essential barriers to protecting corporate networks and devices. A firewall acts as a filter that blocks suspicious or unauthorized connections, while antivirus detects and removes malware before it can harm systems.
Many basic antivirus and firewall solutions are affordable for SMBs and can be easily configured. Additionally, some cloud security tools offer protection without requiring expensive infrastructure, allowing businesses to improve their security without a significant investment in hardware.
Back up critical data regularly
Data loss can occur due to cyberattacks, technical failures, or human error. To mitigate these risks, it is vital to implement a data backup strategy. It is recommended to follow the 3-2-1 rule:
- Keep three copies of important data.
- Store them in two different formats (for example, on a server and on an external drive).
- Keep at least one copy off-site or in the cloud.
Using cloud storage services with encryption and restricted access can be a cost-effective and secure option for protecting company information.
