🔐 Sessie: Mind the GDAP – Crossing Tenants Without Crossing the Line Werk je nog steeds met GDAP om klantomgevingen te beheren? Dan is het tijd om verder te kijken. Op 2 juni laat Microsoft MVP Michael van Horenbeeck zien hoe je cross-tenant toegang inricht op een manier die veilig, schaalbaar en beheersbaar is. In deze sessie ontdek je hoe MSSP’s en klanten kunnen overstappen van overgeprivilegieerde toegang naar een slimmere aanpak met secure B2B collaboration accounts, gecombineerd met just-in-time access, Conditional Access en policy control. 👉 In deze sessie leer je: • waarom traditionele GDAP-configuraties vaak onnodige risico’s introduceren • hoe je slimmere cross-tenant toegang ontwerpt • hoe veilige delegatie er in de praktijk uitziet • welke do’s en don’ts horen bij MSSP-klantrelaties die goed zijn ingericht Werk je met meerdere tenants, beheer je klantomgevingen, of wil je voorkomen dat je letterlijk de sleutels weggeeft, dan wil je deze sessie niet missen. 👉 Registreer nu: expertslive.nl/register/ 📅 1–2 juni 2026 📍 NBC Congrescentrum, Nieuwegein #ExpertsLiveNL #Security #GDAP

I'm still in disbelief and incredibly excited! Because of how big Security Exposure Management is and how much effort went into it, I truly expected it to be a standalone license Instead, parts of it are available in E3, and it's then enriched by whatever else you have 🤯

Ruthless prioritization key to security success - you can’t mitigate every risk in security, but you also can't just stick to one the technology you know. This visual is from the MCRA slides you can download from aka.ms/MCRA (1/x)
