Traditional architectures were centered around a perimeter-based security model, with the data center as the central hub for all network traffic. This architecture forced IT departments to backhaul traffic to the data center for security reasons, significantly impacting cloud application performance. Traditional network architecture was also complex, with many devices and vendors to manage. It was prone to inconsistent security policies across branch offices as legacy devices had to be manually configured. Additionally, with hybrid working, IT departments are struggling to provide secure access to remote employees and protect critical SaaS applications.
