Airlock Digital

Airlock Digital provides enterprise application control and allowlisting software built on a deny-by-default model: only explicitly trusted applications, scripts, and processes are permitted to run, and everything else is blocked outright. Policies can be defined at the file, path, publisher, or parent-process level and are informed by VirusTotal intelligence, with purpose-built workflows designed to make allowlisting — historically seen as too operationally heavy for most organizations — practical to deploy and maintain at enterprise scale, including in OT and legacy environments.

Based in Adelaide, Australia, with an additional office in Canberra, Airlock Digital has built its reputation partly through alignment with the Australian Cyber Security Centre’s Essential Eight framework, which identifies application control as one of the most effective baseline mitigations against ransomware and malware. Deny-by-default allowlisting is not a new security concept, but Airlock’s execution — reducing the staffing and operational burden that historically made allowlisting impractical — is what differentiates it from legacy application-control tools.
