ITDR: Microsoft 365 Account Protection

Identity threat detection and response (ITDR) protects the logins your staff use every day, especially Microsoft 365 email. Many healthcare breaches don't start with a virus. They start with a stolen password and someone quietly reading a staff member's inbox.

Cytek ITDR is part of the Safeguard™ platform, watched by our analysts 24/7.

01

What ITDR watches for

  • Sign-ins from unusual countries or impossible locations.
  • New inbox rules that forward or hide email, a classic sign of a compromised account.
  • MFA changes, password resets and admin rights you did not expect.
  • Risky third-party apps granted access to mailboxes.

When we confirm a threat, we lock the account and end active sessions, then walk you through recovery.

02

Why email accounts are the target

A practice inbox is full of patient names, referrals, insurance details and invoices. A compromised account can mean a reportable breach, and attackers also use it to send fake invoices to your vendors and patients.

MFA helps a lot, but attackers now steal login sessions and trick staff into approving prompts, so monitoring still matters.

HIPAA

The HIPAA rules it helps you meet

  • Person or entity authentication (45 CFR 164.312(d)): verify that a person seeking access to ePHI is the one claimed.
  • Log-in monitoring (164.308(a)(5)(ii)(C)).
  • Security incident procedures (164.308(a)(6)).

HHS's proposed Security Rule update would also require MFA for access to ePHI, with limited exceptions. See is Microsoft 365 HIPAA compliant?

FAQ

Frequently asked questions

What is ITDR?

Tools and people that watch user accounts for signs of takeover and respond fast when one is compromised.

We already have MFA. Do we still need ITDR?

MFA blocks most password attacks, but not all. Attackers use phishing kits that steal the session after MFA, or keep sending prompts until someone approves one. ITDR catches what gets through.

What happens if an account is compromised?

We lock the account and end active sessions, then help you secure it and work out what was accessed, which matters for HIPAA breach decisions.

Is ITDR required by HIPAA?

Not by name, but HIPAA requires you to authenticate users, monitor log-ins and respond to incidents. ITDR does that for your cloud accounts.
