CriticalBlue is an established company with a strong track record in providing solutions across multiple sectors of the technology industry.


CriticalBlue is a Scottish technology company with deep expertise in mobile operating systems and application security. It's primary product, Approov, is an API security solution for mobile centric enterprises. Approov enables enterprises to ensure that only genuine instances of their mobile apps, running on safe mobile devices, can access their APIs. Deploying Approov shields businesses from data scraping, credential stuffing, account takeover, automated onboarding, fake apps and the exploitation of any API vulnerabilities.


The mobile channel is the hardest to protect because you don't control who downloads and studies your app. Approov is easy to add to your platform and it is utilized to independently verify your mobile app alongside your user authentication - control what is using your APIs, as well as who.


CriticalBlue utilises a wide range of client plus server side technologies and languages to implement the security analysis. A mobile (iOS and Android) SDK component includes low level dynamic analysis of the running app and its environment, complemented by cloud service implemented on both AWS and GCP to analyse live telemetry from apps running in the field.
