The Sentinel DataVault is TESSERA CORPONATION's flagship corporate-issue BCI, engineered for mid-to-senior employees handling sensitive proprietary data, financial projections, and classified internal communications. The implant features a 512-bit quantum-resistant encryption layer applied to all neural memory consolidation during REM cycles, effectively partitioning work-related cognitive data into a sealed enclave inaccessible to external scanning or neural intrusion attempts. A passive intrusion detection module monitors synaptic I/O traffic in real time, flagging anomalous extraction signatures and triggering a neural firewall lockdown within 0.003 seconds of detection. Compartmentalization protocols allow the device to segment the user's working memory into up to six isolated cognitive partitions, each requiring biometric neural-signature authentication to access — meaning even the user cannot cross-contaminate classified project data without deliberate authorization.

The DataVault is the de facto standard for Tessera's own CorpSec divisions and is widely issued to corporate lawyers, senior analysts, account executives, and compliance officers operating in the mid-Shelf to Ledge tiers of GLMZ's corporate ecosystem. Street workers call it 'the Lockbox' with a mix of contempt and envy — it's a status marker that signals you have secrets worth protecting, and by extension, a salary worth envying. Black-market neural hackers specifically target DataVault users as high-value marks, knowing that a successful extraction yields premium-grade proprietary intelligence. Tessera employees joke grimly that the implant makes them worth more unconscious than alive.
