DORA Is Now Final – Here’s What CISOs and Boards Must Act On Today
🛡️ DORA Just Became Mandatory – Are You Ready to Prove It?
🧠 Financial entities are waking up to a hard truth:
💥 DORA isn’t just about systems – it’s about people, vendors, and visibility.
⏳ The compliance deadline is January 17, 2025. But most haven’t started addressing the weakest link – the human attack surface.
🚨 DORA now demands you monitor and test every ICT risk – including third parties. That means your social engineering blind spots could now trigger a compliance failure.
🎯 This isn’t theory. It’s operational reality.
✅ Boards are now directly accountable for digital risk governance.
✅ Simulations must go beyond tech – into phishing, impersonation, and insider threats.
✅ Your cyber resilience must now be provable.
🔎 What’s most surprising?
DORA’s final standards expect proactive testing of non-technical risk vectors – and most orgs are still training humans once a year.
That’s a ticking bomb.
👁️🗨️ AUMINT Trident delivers DORA-ready human-layer simulations, exposure analysis, and board-grade insights.
⚡ Don’t get caught flat-footed.
