8x8, Inc. (U.S)

8x8, Inc. has been in the cloud communications game since 1987 - over three decades of building out the plumbing that enterprises rely on for voice, video, and contact center traffic. The company's platform integrates Unified Communications, Contact Center, and CPaaS APIs into a single stack, with AI wired in at every layer. That convergence matters from a security perspective: one platform means one attack surface, but also one control plane to defend.

The threat model here is substantial. 8x8 processes high-volume, real-time communications data - call audio, chat transcripts, customer metadata, API payloads - for organizations across business communications and customer experience verticals. Protecting that pipeline means defending cloud infrastructure at scale, securing API endpoints that third parties build against, and ensuring the AI models embedded in the platform aren't vectors for data leakage or manipulation. The technical domains span AI, cloud-native architectures, and communications protocols - a blend that demands engineers who understand both the specificity of real-time media security and the breadth of modern cloud security posture.

For security professionals, the draw is complexity at scale: a platform serving enterprise contact centers and UC environments where uptime, data integrity, and compliance aren't optional. The company's stated focus on seamless, integrated communication means security can't be bolted on - it has to be architected into the core product and the APIs that extend it.
