CST VerdictShort answer
Mid-market and enterprise teams managing Microsoft Teams or Webex who need enforceable barriers between business units will find SphereShield's ethical wall the strongest reason to adopt it; the granular activity-level controls (messaging, file sharing, audio/video, recording, desktop sharing) actually prevent lateral communication rather than just logging it. The real-time inline DLP inspection across files, messages, and images before content reaches the cloud covers the PR.DS and DE.CM vectors most compliance programs demand. Skip this if you're already committed to a DLP vendor like Forcepoint or Symantec and just need archiving; SphereShield's strength is enforcement, not integration into an existing stack. Security teams protecting AI applications in production need Protect AI Layer because it catches multi-turn attacks and RAG poisoning that static scanning misses entirely. The platform monitors 27 turnkey policies mapped to NIST and MITRE frameworks with automated remediation, covering the full detection-to-response chain that most AI security tools abandon after flagging a problem. Skip this if you're looking for pre-deployment code scanning; Protect AI Layer is runtime-only and assumes your AI app is already running.
