The rise of e-commerce has radically transformed how we conduct financial transactions, facilitating access to goods and services globally. However, this convenience comes with a significant increase in the risk of fraud, data theft, and other cyber threats. The use of tools like Virtual Private Networks (VPNs) is common to try to protect these transactions; however, relying solely on them may not be enough. In this article, we will explore effective strategies that promote security in online transactions. Understanding the Threats: Beyond VPNs It is often assumed that using a VPN is the ultimate solution for safeguarding information online. However, it is crucial to understand that threats are diverse and not limited to unauthorized network access. Phishing attacks, malware, and ransomware are just some of the ways cybercriminals try to access users\' sensitive data. Therefore, while a VPN can offer some privacy by encrypting your internet connection, it doesn\'t prevent other inherent risks.

Multi-factor authentication: an indispensable requirement

One of the most effective strategies for securing online transactions is to implement multi-factor authentication (MFA). This approach requires users to provide multiple forms of identification before accessing their accounts. This can include something they know (a password), something they have (a code sent to their phone or a hardware token), and something they are (fingerprints or facial recognition). While this method isn\'t foolproof, it significantly increases the difficulty for attackers to compromise accounts.

Practical example of MFA

Let\'s consider an online banking platform. If a user attempts to log in from a new device, in addition to entering their username and password, they must receive a code on their mobile phone to complete the login. This means that even if an attacker obtains the user\'s password through techniques like phishing, they would still need physical access to the user\'s phone to carry out the fraud. It\'s important to note that each additional layer requires more effort from the user; however, the security benefits justify this inconvenience.

Encryption: Protecting Sensitive Information

Encryption also plays a crucial role in protecting online transactions. Ensuring that any sensitive information transmitted is encrypted prevents hackers from intercepting data during transmission. Protocols like HTTPS are essential for establishing a secure connection between the user\'s browser and the web server. Likewise, advanced encryption technologies can be implemented by companies to protect information not only during transmission, but also while it is stored on their servers.

Encryption in Business Communication

An interesting example is the use of end-to-end encryption in messaging applications like WhatsApp or Signal, where only the participants in a conversation can read the exchanged messages. Applying this idea to the business environment, it could be implemented in emails with sensitive data to ensure that only the sender and recipient have access to that information.

User Education: A Fundamental Key

Despite having advanced technologies and robust systems to protect online transactions, the human factor remains one of the biggest vulnerabilities.Ongoing education on safe practices and fraud detection is crucial. Informative campaigns on how to recognize suspicious emails or fraudulent SMS messages empower end users and make them a first line of defense against cyberattacks.

Future Trends in Online Security

It is impossible to talk about the future without considering artificial intelligence (AI) and its growing role in cybersecurity. Algorithms capable of detecting unusual patterns can help identify fraudulent activities before they even materialize. Furthermore, biometrics continues to evolve, which could take secure authentication to unprecedented levels.

The Role of Blockchain in Transactions

Although still under development, blockchain-based technologies offer a high level of security due to their decentralized and immutable nature. The most conventional applications have been primarily in financial environments; however, we can imagine a future where every transaction is recorded and verified without the need for traditional intermediaries.
