Stop account takeovers before they become breaches

Session Cookie Replayed

One compromised identity is all it takes. Huntress detects and stops account takeovers (ATOs) before attackers can steal data or cause damage.

Why traditional security tools fail to stop account takeovers

Attackers don't break in anymore, they just log in.

Today's account takeover attacks use stolen passwords, stolen session cookies, OAuth abuse, device code phishing, infostealers, adversary-in-the-middle attacks, and countless other identity techniques to bypass traditional defenses (even MFA). Once inside, attackers look like legitimate users, making them incredibly difficult to detect with conventional security tools.

The Huntress Agentic Security Platform protects the entire identity attack chain. Combined with our 24/7 AI-Centric SOC, Huntress helps stop account takeovers before they become ransomware, business email compromise, or data theft.

Account Takeover attack chain

No manual investigations.
No waiting for attackers to make the first move.

The worst moment in an account takeover isn't the phishing email.

It's discovering hours later that an attacker has been quietly logging in, creating persistence, stealing sensitive data, authorizing malicious applications, or moving throughout your environment.

With the Huntress 24/7 AI-centric SOC, those critical first response actions happen within minutes.

We automatically:

  • Disable compromised identities
  • Revoke active sessions
  • Remove malicious persistence
  • Investigate suspicious identity activity
  • Stop attackers before they can escalate access or steal additional data

They log in,
we stop them.

Traditional security tools focus on keeping attackers out. Huntress helps strengthen your defenses and stops attackers from gaining ground if they get in.

Our SOC continuously hunts for real attacker behavior, not just suspicious events, to give you expert investigation, verified incident reports, and rapid containment around the clock.

Whether an attacker steals credentials through phishing, hijacks a session, abuses OAuth permissions, or compromises an account through another identity attack, Huntress helps shut them down before small compromises become major breaches.

REAL LIFE STORIES

Account takeover attacks don't stop at the first login

As RAFTRx rapidly expanded through acquisitions, its two-person IT team faced an increasing number of identity threats, including phishing emails, suspicious logins, and compromised user accounts. They needed a way to detect and stop account takeovers without adding more tools or more work.

With Huntress Managed ITDR, RAFTRx gained immediate visibility into suspicious identity activity across seven Microsoft 365 tenants. Huntress quickly identified compromised accounts and suspicious logins, while the 24/7 SOC investigated the activity and contained threats before they could turn into account takeovers or broader business impact. When an employee clicked a malicious link, Huntress had already investigated and contained the threat before the user even reported it.

Frequently Asked Questions

Not anymore.

Email is often the first target, but attackers also abuse SharePoint, OneDrive, Teams, Entra ID, Azure resources, and other cloud services once they've compromised an identity. Modern account takeover is an identity problem—not just an email problem.

Yes.

Modern account takeover extends far beyond stolen passwords. Managed ITDR detects session hijacking, rogue OAuth applications, malicious inbox rules, device code phishing, unexpected logins, VPN abuse, suspicious geolocations, credential theft, and numerous other post-authentication identity attacks.

Huntress is designed specifically for teams like yours. Our human-led, AI-centric SOC acts as your dedicated extension, providing the necessary expertise and 24/7 coverage without the massive cost or complexity of building or scaling your own security team. We handle the hard parts—from threat hunting investigation, and response, to fully managed security awareness learning plans—and deliver concise, verified actions to your team. This model ensures you get enterprise-grade security outcomes without needing enterprise resources.

Speed matters.

Our SOC investigates verified account takeover activity with an average mean time to respond of under three minutes. We don't simply generate alerts - we begin containment by revoking sessions, disabling compromised identities, and removing attacker persistence before additional damage occurs.

Microsoft provides powerful security capabilities, but many organizations still need experts to continuously monitor identity activity, investigate alerts, and respond quickly.

Huntress combines our Agentic Security Platform with a 24/7 AI-centric SOC that validates suspicious activity, investigates identity attacks, and initiates containment with an industry-leading 3-minute average response time.
