Security Compliance center - https://protection.office.com/homepage
From SCC portal one used to manage Exchange Online Protection and Microsoft Defender for Office 365 to protect your email and collaboration services, and ensure compliance to various data-handling regulations.
NOTE: Most tenants using the security sections of the Office 365 Security & Compliance Center should now be redirected to the Microsoft 365 Defender portal at security.microsoft.com
We are in the final stage of retiring the office 365 Security and Compliance center portal. All solutions and features completely migrated to the Microsoft 365 Defender portal, Microsoft Purview compliance portal, and Exchange admin center.
