What is Encryption?
Encryption converts readable data into an unreadable format using mathematical algorithms, making it accessible only to those with the correct decryption key. It protects data at rest (stored files), in transit (network traffic), and in use across devices and cloud services.
Why Encryption matters for Australian businesses
With cyberattacks on Australian businesses increasing year on year, understanding your security tools and strategies is critical. The Australian Cyber Security Centre reports an attack every six minutes, and small and medium businesses are increasingly targeted. Having the right defences in place is not optional — it is essential for protecting your data, your clients, and your reputation.
For small and medium businesses in particular, encryption plays a key role in maintaining a secure, efficient, and resilient IT environment. Whether you are reviewing your current setup or planning improvements, understanding encryption will help you have more informed conversations with your IT provider and make better decisions for your business.

Frequently Asked Questions
What is encryption?
Encryption scrambles data into an unreadable form that can only be unlocked with the correct key, protecting it from anyone who is not authorised, whether the data is stored on a device or travelling across a network.
What is the difference between encryption at rest and in transit?
Encryption at rest protects stored data on disks, backups or databases if a device is lost or stolen. Encryption in transit protects data as it moves between systems, such as over the internet. Both are needed for proper protection.
Does encryption help with compliance?
Yes. Encryption is widely expected under privacy and security frameworks and can reduce the impact of a breach, since properly encrypted data is far harder for attackers to misuse. It is a key part of protecting client information.
