What is DLP (Data Loss Prevention)?
DLP refers to tools and policies that prevent sensitive data from being accidentally or maliciously shared, leaked, or exfiltrated outside your organisation. DLP monitors email, file transfers, cloud storage, and USB devices to enforce data handling rules.
Why DLP 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, dlp plays a key role in maintaining a secure, efficient, and resilient IT environment. Whether you are reviewing your current setup or planning improvements, understanding dlp will help you have more informed conversations with your IT provider and make better decisions for your business.
