Stop Sophisticated Account Takeover Fraud
FASTER INVESTIGATIONS
Help Your Team Act Faster and Accomplish More
Investigation workflows turn scattered session data into a fast, clear view of what happened, so teams spend less time piecing together sessions and more time taking confident, informed action.
- GenAI-powered summaries surface cross-session behavior, flagging what needs review
- Workflows unify investigation and action for account-risk decisions
- Automation handles routine decisions, freeing teams for higher-risk cases

IMPROVED ACCOUNT DEFENSE
Trust That Extends Beyond Sign-In
Real-time behavioral signals layer onto every login and pair with durable device fingerprinting that persists across sessions, giving teams richer context for every account-defense decision instead of a single point-in-time check.
- Real-time behavioral analysis adds context beyond isolated login events
- Durable device fingerprinting strengthens cross-session visibility
- Continuous post-login monitoring helps stop risky activity after sign-in

LOWER USER FRICTION
Challenge the Session, Not the Whole Account
Controls apply at the session level, so one suspicious session does not force a trusted account into a full lockout. As trusted behavior is recognized over time, strong users can move through with less friction instead of more.
- Session-level controls help contain risk without overreacting at the account level
- Stronger trusted-user recognition reduces friction for returning users over time
- Native email and SMS verification add step-up when warranted

Sift brings deeper context to every account defense decision, with insight from 1 trillion annual events, 16,000 risk signals, and 2.1 billion authentic digital citizens. Stop more fraud with fewer reviews, fewer false positives, and less friction.

Frequently Asked Questions
How does Sift detect and prevent account takeover?
Sift helps detect account takeover by evaluating each login and user session against real-time risk signals such as device intelligence, behavioral patterns, unusual account changes, and broader network insights that can reveal threats a single business may not see on its own. Based on that risk, teams can block a session, trigger step-up authentication, route it for review, or continue monitoring after login, helping stop account takeover before it turns into loss or customer churn.
How is Sift Account Defense different from MFA alone?
MFA is an important control, but on its own it does not determine which sessions are actually risky or adapt well to evolving attack tactics. Sift adds a risk-decision layer on top of authentication by combining device, behavioral, velocity, and network signals to help teams decide when to allow access, when to trigger MFA, and when to take stronger action, so protection is based on real session risk rather than a one-size-fits-all challenge.
How does Sift stop account takeover without adding friction for trusted users?
Sift is designed to apply friction selectively at the session level, so trusted users can move through login and post-login activity with less interruption while suspicious activity receives additional scrutiny. By combining real-time risk scoring with adaptive authentication and ongoing monitoring after login, Sift helps businesses challenge the moments that look risky without forcing every user through the same experience.
How does Sift integrate with our existing identity and authentication stack?
Sift is built to augment existing identity and authentication investments rather than replace them, with low-code integrations for leading CIAM platforms and flexible event-based implementation options for teams with custom stacks. Businesses can send key login and account events into Sift, use Sift risk signals inside their existing orchestration or authentication flows, and trigger actions such as allow, challenge, or review based on the level of risk.
