Encryption is a security technique that converts readable data into unreadable code using a mathematical algorithm and a digital key. Only parties with the correct decryption key can see the original information again. This technique protects sensitive data such as customer data, passwords and payment information from unauthorized access, both during transmission over the Internet and when stored on servers. For SMBs, encryption is essential when processing personal data according to the AVG and handling online transactions securely.
How encryption works technically
In encryption, an algorithm performs a series of mathematical operations on the original data. This process uses a key, a unique set of bits that determines how the data is transformed. There are two main types: symmetric encryption in which the same key encrypts and decrypts, and asymmetric encryption with a public key for encryption and a private key for decryption. Modern encryption standards such as AES-256 use keys of 256 bits, yielding billions of possible combinations. This makes brute-force attacks virtually impossible. The strength depends on three factors: the length of the key, the quality of the algorithm and how securely you manage the keys.
From military technology to everyday Internet use
Encryption originally originated in military contexts, where secret messages needed to be protected from enemy interception. With the rise of the Internet in the 1990s, encryption became accessible for commercial use. The introduction of SSL certificates made it possible to secure Web traffic. Today, encryption is standard in virtually all online communications. Every website with HTTPS, every WhatsApp message and every online payment uses encryption. For SMEs, this is no longer a nice-to-have but a legal requirement under the AVG when processing personal data. Customers also expect their data to be handled securely, which makes encryption a competitive factor.
What encryption brings to your business
Als MKB-ondernemer bescherm je met versleuteling de gegevens van je klanten tegen datalekken en cyberaanvallen. Dit verlaagt het risico op boetes van de Autoriteit Persoonsgegevens en voorkomt reputatieschade. Bij een webshop zorgt versleuteling ervoor dat betalingsgegevens veilig worden verwerkt, wat essentieel is voor klantvertrouwen. Ook interne communicatie via e-mail of projectmanagement-tools blijft vertrouwelijk. In de praktijk zien we bij MKB-klanten dat een goede technische basis met versleuteling de eerste stap is naar AVG-compliance. Het voorkomt dat gevoelige offertes, contracten of klantdossiers in verkeerde handen vallen. Voor bedrijven die met authenticatie en inloggegevens werken, is versleuteling van wachtwoorden in databases onmisbaar.
