Cloud Detection & Response (CDR)

Your Cloud Is Where Attackers Go First

Most business data now lives in Microsoft 365, Google Workspace and other cloud apps, and attackers know it. Instead of breaking into a server, they steal a password, sign in from another country, create a hidden inbox rule and quietly redirect invoices. Endpoint protection never sees it, because no device was involved.

Cloud detection and response (CDR) closes that gap. It monitors your cloud identities and applications around the clock and responds the moment something looks wrong.

What Simplitfy CDR Watches For

  • Suspicious sign-ins: impossible travel, unfamiliar countries, anonymizing VPNs and token theft
  • Business email compromise: malicious inbox rules, forwarding to outside addresses, mass deletions
  • Risky OAuth apps granted access to mailboxes and files
  • Privilege changes such as new global admins or disabled MFA
  • Unusual file activity like mass downloads or sharing to personal accounts

How We Respond

Alerts flow into our 24/7 SOC. When a threat is confirmed, we lock the account, revoke active sessions, remove malicious rules and walk you through what happened, often within minutes.

Part of a Layered Defense

CDR works alongside EDR on your devices, email security in your inboxes and Microsoft 365 backup as your last line of recovery.

Questions

Frequently Asked Questions

What is cloud detection and response?

CDR continuously monitors cloud identities and applications, such as Microsoft 365 and Entra ID, for signs of compromise like suspicious sign-ins, malicious inbox rules and risky app permissions, and responds by locking accounts and revoking sessions.

Do I need CDR if I already have EDR?

Yes. EDR protects devices. Many attacks today happen entirely in the cloud with stolen credentials and never touch a device, so CDR covers that blind spot.
