Security for remote teams and the AI they use
Identity threat detection (ITDR)

Identity threat detection and response: stop account takeovers before they spread

Most attacks on remote teams never touch a laptop. They start with a stolen password, a hijacked session or a tricked MFA prompt, then move through email and cloud apps. Identity threat detection watches your sign-ins and accounts around the clock and responds the moment one is taken over.

Your people’s logins are the new front door

When a team works remotely, there’s no office network to break into. The valuable things live in email, file storage and cloud apps, and the way in is an account. That’s why so many attacks now start with identity: a phished password, an MFA prompt someone approves without thinking, or a session token stolen from a browser.

Once inside an account, attackers move quietly. They read mail to learn who pays whom, set up forwarding rules to keep watching, connect malicious apps that keep access even after a password reset, and send convincing invoice fraud from a real colleague’s mailbox. None of that touches a laptop, so device protection alone won’t see it.

What identity threat detection watches for

  • Impossible or unusual sign-ins. Logins from new countries, unfamiliar devices or two places at once.
  • MFA abuse. Bursts of push prompts, new MFA methods added to an account, or approvals at odd hours.
  • Session and token theft. Sessions reused from unexpected locations after phishing that captures a completed sign-in.
  • Mailbox tampering. New forwarding, delete or move rules that hide an attacker’s activity.
  • Risky app consents. Third-party apps granted access to mail or files they shouldn’t need.
  • Privilege changes. New admins, role changes and changes to security settings.

How we respond

Detection only helps if someone acts quickly. When an alert is real, our analysts:

  1. Contain the account. Block sign-in or force a reset, and revoke active sessions and tokens.
  2. Remove persistence. Delete malicious inbox rules, revoke rogue app permissions and remove attacker-added MFA methods.
  3. Scope the damage. Review what the attacker read, sent or changed.
  4. Report and harden. Explain what happened in plain English and close the gap that let it happen.

Part of a layered defense

Identity threat detection works best alongside EDR / MDR on your devices, zero trust access to limit what any single account can reach, and a business password manager so fewer passwords are reused or phished in the first place.

Frequently asked questions

What is identity threat detection and response (ITDR)?

ITDR is the practice of monitoring user accounts and sign-ins for signs of compromise, such as logins from impossible locations, suspicious MFA activity or stolen session tokens, and responding quickly by locking the account, ending its sessions and undoing anything the attacker changed.

How is ITDR different from EDR or MDR?

EDR and MDR watch devices: laptops, desktops and servers. ITDR watches identities: the accounts people use to sign in to email and cloud apps. Many modern attacks skip the device entirely and use a stolen login from the attacker's own machine, so you need both.

Doesn't multi-factor authentication already stop account takeovers?

MFA stops most password-only attacks, but attackers have adapted. Phishing kits can capture a session after the user completes MFA, people approve push prompts they didn't start, and stolen session tokens can bypass sign-in entirely. ITDR catches what happens after a sign-in succeeds.

Which platforms do you monitor?

We focus on the identity and productivity platforms remote teams run on, typically Microsoft 365 and Microsoft Entra ID or Google Workspace, plus the business apps connected to them through single sign-on.

What happens when you find a compromised account?

We contain it first: disable the account or force a password reset, revoke active sessions and tokens, and remove attacker changes like forwarding rules or rogue app permissions. Then we tell you what happened, what was accessed and what to do next.
