When it comes to building applications intended for external users, high levels of security need to be included, but it can be a delicate balance between implementing robust security controls and damaging the user experience.

Traditional security controls designed for enterprises, like two factor authentication often aren’t a good fit for consumers.  Your users want to be able to get access to your services quickly and without fuss, and any friction added to a users journey can risks losing you valuable subscribers or worse – revenue.

The reality is however, that one of the biggest vulnerabilities to consumer applications is the consumer themselves, and specifically their password behaviour.

End users don’t understand the risks associated with weak password choices, or that using the same password across multiple applications introduces a security risk to your online service, but more importantly they don’t really care.

Due to the fact that poor user password hygiene across internet applications remains a top security threat to application owners Threat Status have developed Arc specifically to minimise that threat with zero impact on your users authentication experience.​
