Azure Security Tool Selection
Needs Assessment
First, you need to know what your group needs for safety. Think about the kind of data you use. Check what rules you must follow. Look at what dangers you might face. When picking Azure Security tools, focus on what matters most:
AI-powered threat intelligence helps you look at security data and guess risks. Tools like Microsoft Defender for Cloud use smart tech to find problems early.
Zero trust security ideas keep your cloud safe. Identity-based access control and least privilege rules, set by Microsoft Entra ID, lower risk.
Quantum-resistant encryption keeps your data safe from new threats. Azure gives you hybrid encryption and works on post-quantum cryptography.
Check each tool’s limits, like how hard it is to set up, what clouds it works with, how it connects to other tools, and how it affects your work.
Tip: Pick security tools that fit your business needs and risks. This way, you get good protection without making things too hard.
