Why Does Data Encryption Matter?

In a world where data is constantly being collected, transmitted, and stored, protecting that information has never been more important. From personal identification numbers and access logs to photos and sensitive documentation, data is one of your most valuable assets.
But first, what exactly is data encryption?
Data encryption is the process of converting readable information into scrambled code that can only be deciphered with a unique key. In other words, it’s like putting your data into a secure digital vault. Without the key, the information remains unreadable—even if someone gets their hands on it.
Encryption ensures data security in two key states:
In transit – when data is being sent from one place to another (e.g., from a scanner to a server)
At rest – when data is stored on a device or in a database

Why Is Encryption So Important?
For any organisation that handles personal or sensitive information, data encryption is more than just a technical measure, it’s a critical safeguard.
Here's why:
1. It prevents unauthorised access
Even if data is intercepted or leaked, encryption ensures it can’t be read or used without the proper key.
2. It helps meet legal and compliance standards
In South Africa, the Protection of Personal Information Act (POPIA) outlines strict requirements for how data must be secured. Encryption is one of the most effective ways to meet these obligations.
3. It reduces risk in the event of a breach
Should a breach occur, encrypted data is far less likely to result in harm. This adds an important layer of protection for both organisations and individuals.
4. It builds trust with clients and users
People expect their information to be handled responsibly. Encryption helps ensure that expectation is met.
How SA Technologies Uses Encryption
At SA Technologies, we collect and manage a significant amount of sensitive data through our VisitMe and IntelliGuard solutions.
That’s why we’ve built strong encryption practices into every stage of our systems:
On-device encryption: All data captured on VisitMe scanners is stored locally in an encrypted database until it is synced.
Secure transmission: Data is transmitted to our servers over encrypted HTTPS channels, preventing interception or tampering during transfer.
Encrypted backend storage: Sensitive information is stored in a fully encrypted MySQL database hosted in a secure AWS environment with restricted access.
Cloud file protection: Images, documents, and other static files are stored on encrypted AWS S3 cloud storage, only accessible through authorised server routes.
This multi-layered approach ensures that your data remains secure from the moment it’s captured to the moment it’s deleted.
Final Thoughts
Data encryption isn’t just about ticking a compliance box—it’s about making sure the personal information you’re responsible for is never left vulnerable. For data collection companies, especially those in access control and visitor management, encryption is essential to protect people, maintain trust, and operate responsibly.
In short: when data is encrypted, it’s safe. And that’s exactly how it should be.
