IdentityProtect
Stop account takeover at the login.
Attackers don't break in anymore — they log in. Passwords get phished, leaked, and traded, and once someone has a valid one, most systems roll out the welcome mat. IdentityProtect blocks unauthorized logins and session hijacks the moment they happen — so a stolen password isn't enough to get in.
Part of the 1stProtect platform. One agent. No slowdown.
The problem IdentityProtect solves.
The front door is now the favorite way in. Attackers don't need an exploit when they can simply sign in as someone who already has access:
Stolen passwords are a question of when, not if.
Credentials are phished, leaked in breaches, and bought in bulk every day. Sooner or later, an attacker has a valid one to your environment.
A valid password looks like a welcome.
To most systems, the right password is the right person. An attacker who logs in with stolen credentials — or quietly hijacks a session that's already open — walks straight in looking completely legitimate.
IdentityProtect stops the unauthorized login itself — so having the password isn't the same as getting in.
How it works
Three things. Nothing you don't need.
Stand guard at every login.
IdentityProtect checks each login and session attempt against your policy, in real time — on the machine, as it happens.
Cancel the ones that don't belong.
When an attempt is unauthorized — like someone trying to take over a session that's already active — IdentityProtect cancels the logon on the spot. The right password isn't enough.
Know who tried to get in.
Every blocked attempt lands on the risks page with the details, so you can see exactly who tried to log in or hijack a session, and when.
One engine. 22 modules.
IdentityProtect doesn't work alone.
It runs on the same single SIGMA engine as the rest of 1stProtect — working alongside CredentialProtect to keep credentials from being stolen in the first place, and ADProtect to shut down Active Directory attacks. One agent, one policy, no conflicts — online, offline, or fully air-gapped.
What it stops:
- —Logins using stolen or compromised credentials
- —Attempts to hijack an active user session
- —Unauthorized access even when the password is correct
- —Account takeover from phished, leaked, or purchased credentials
- —Quiet lateral movement using valid-looking logins
See it in action
Watch it cancel a session hijack.
The setup. A Windows server runs with the 1stProtect agent installed and one real user already signed in and active.
The attack. An attacker who has stolen that user's password tries to hijack the active session. At the login screen, they enter the compromised password.
The block. IdentityProtect cancels the logon. The password is correct — and it still doesn't matter. The attempt is denied.
The record. On the risks page, an alert shows a login attempt matching the user who's already signed in — a session hijack — captured with the full details.
Deploy without breaking anything
Start in Audit Mode. Enforce when you're ready.
IdentityProtect ships in Audit Mode by default. Watch exactly what's trying to log in across your environment — and exactly what would be blocked — without stopping a single thing. Baseline your environment, whitelist what's legitimate, then flip to Enforcement Mode with one config change.

Built by the people who built the industry
1stProtect's team comes from CrowdStrike, SentinelOne, Check Point, Splunk, Cisco, Oracle, McAfee, Symantec, and NTT Data — the engineers who defined modern endpoint security, now building runtime protection for what comes next.
See IdentityProtect on your endpoints.
We'll deploy in Audit Mode and show you, in your own environment, exactly what's trying to log in today — then stop the attempts that don't belong.
For your security & engineering team
IdentityProtect enforces identity policy on interactive logon and session-access attempts through the user-space SIGMA engine — blocking session hijacking and credential misuse even when valid credentials are presented, including connection attempts matching a currently logged-on user. Each denial is recorded by the on-host MCP AI Investigator and streams to your SIEM/SOAR (Splunk, Datadog, Elastic) via JSON, gRPC, MCP, or Syslog. <1% CPU, real-time enforcement, 100% offline-capable, with Audit and Enforcement modes.
