AI technology allows security teams to concentrate on the right things.

Microsoft Entra and AI Identity Security

Identity is becoming the main target for hackers.

Not all attacks start with gaining access to the system; they start with obtaining user credentials, password, or token.

Microsoft Entra allows organizations to control their digital identities and access.

AI-powered security features are useful for detecting:

• Unusual login attempts.
• Suspicious access activities.
• Identity threats.
• Account compromise.

It becomes just as important to protect identity as it is to protect devices.

AI-Powered Phishing Protection

Phishing is one of the most widespread cybersecurity threats.

Attackers create various emails, web pages, and other kinds of messages to fool the user into disclosing sensitive data.

AI allows security tools to monitor:

• Email behavior.
• The sender's reputation.
• Suspicious links and content.
• Message behavior.
• User actions.

Microsoft Defender for Office 365 uses AI-powered technologies to identify malicious emails and defend against phishing campaigns.

It is becoming more important as hackers are starting to use AI to craft more believable messages.

Microsoft Purview and Data Protection

Data Security is yet another key component of Microsoft's AI strategy.

Microsoft Purview assists organizations in discovering, classifying, and protecting their sensitive data.

AI can be utilized for:

• Data Classification
• Risk Detection
• Compliance Management
• Information Protection

There is a lot of sensitive data that organizations have to manage such as client data, financial information, and internal files.
