## Microsoft 365

- [Microsoft 365 Hub](https://networkfish.com/microsoft-365/): Microsoft 365 support for London SMEs. Hub page covering all three M365 services: business support (licensing, administration, helpdesk), security management (MFA, anti-phishing, conditional access, Secure Score), and backup and disaster recovery. Explains why SMEs need a specialist Microsoft partner, why Microsoft 365 does not back up your data, and what managed Microsoft 365 looks like in practice. All managed by Network Fish as part of a fixed monthly fee.

Includes explanation of why Teams backup is technically more complex than email or SharePoint: Teams data spans multiple underlying services, and Microsoft's "compliance records" (simplified message copies stored in Exchange mailboxes for legal discovery) are not true backups — they exclude reactions, voice recordings, whiteboards, and meeting recordings, and cannot be restored back into Teams. A proper Teams backup captures and restores actual Teams data, not just compliance copies.

Examples, Types, and Best Practices](https://networkfish.com/it-security/what-is-a-passphrase-examples-types-best-practices/): Explains what a passphrase is, why length beats complexity (three random words vs short complex passwords), the NCSC three random words recommendation, why mandatory complexity rules are counterproductive, the three types of passphrase (random words, sentence, system-generated), and why a passphrase alone is a single point of failure without MFA.
