What runs in Cellebrite's cloud.

Everything Cellebrite builds runs in a dedicated corporate IT account, separate from the product and FedRAMP environments. Vendor systems stay in their own SaaS.

Six phases, six gates.

Follows the phases and gates in the original brief. Click a bar or a gate for its outputs, the components it delivers, the decisions it closes and its exit criteria.

Phase (click to open) Gate / go-no-go Continuous workstream Year-end holidays Today
Timeline risk. The brief puts discovery and spec in November, development in December, and testing plus a live pilot cycle in January. That's achievable only if the MVP stays limited to Okta, HiBob and Outlook. Slack, Juno, the Talent Management Platform and AI follow in Q2 2027.
10 · Follow-up questions

What we need from Cellebrite IT & engineering.

The technical answers that unblock the next steps. Questions marked Blocks G1 must be answered before the discovery gate closes. Tick questions off as they're answered, then copy the open ones to send.

11 · Risks

What could go wrong.

RiskImpactMitigation
A permission bug exposes ratingsLoss of trust, legal exposureA single policy module, full matrix tests as a launch gate, a separate confidential store, and SIEM alerts
Wrong manager data in HiBobWrong people see or rate goalsValidation and an anomaly hold on sync, plus a data clean-up before the pilot
Very tight timelineQuality and security shortcutsA narrow MVP. Everything else after the pilot
Resistance to full transparencyLow adoption, gaming of goalsVisibility badges, private drafts, comments limited to the manager chain
Multi-country legal constraintsRollout delaysEarly legal opinion, DPIA, rollout in country waves
AI drifting into evaluationRegulatory exposureAI limited to drafting, enforced in the AI gateway
No-code platform holding HR dataFails InfoSec reviewBase44 for prototypes only. Production in Cellebrite's own cloud account
