Cyber Resilience Briefing — April 14, 2025

Executive briefing: Unified communications platforms now carry financial approvals, product roadmaps, and incident bridges. Zeph Tech is enforcing workspace lifecycle policies, retention governance, and insider threat analytics so collaboration stays auditable without slowing teams down.

Key industry signals

Privacy extensions required. ISO/IEC 27701 section 7.3 expects documented processing purposes and retention schedules for collaboration data, elevating the role of workspace classification.
Secure conferencing guidance. ENISA’s guidance on secure video conferencing emphasises identity assurance, encryption, and recording controls that must be mirrored inside collaboration suites.
User awareness still a gap. CIS Control 14 highlights the need for continuous security awareness across collaboration tooling, including training on AI-generated meeting artefacts.

Control alignment

ISO/IEC 27701 7.3. Catalogue personal data stored in chat, meeting recordings, and transcription exports; publish retention SLAs per workspace category.
CIS Control 14.4. Extend security awareness programmes with modules covering secure use of bots, external sharing, and confidential meeting workflows.

Detection and response priorities

Detect when privileged channels disable retention or eDiscovery policies and trigger approval workflows before changes go live.
Alert on automation accounts requesting tenant-wide scopes or exporting content to unmanaged locations.

Enablement moves

Provide executive assistants and chief-of-staff teams with secure meeting quick-start guides covering classification, recording decisions, and guest policies.
Launch collaboration hygiene scorecards so department leads see retention compliance, external guest usage, and bot reviews at a glance.
