Modern ATO Campaigns Exploit Anonymized Infrastructure.

Modern authentication defenses often fail not just because credentials are weak, but because attackers hide abusive login activity behind anonymized infrastructure. When login decisions lack network context, teams are forced to rely on blunt controls that increase friction for legitimate users.

Spur enriches authentication events with infrastructure intelligence, enabling more accurate risk assessment and proportional controls at the point of login.

How Spur Reduces Account Takeover Risk.

Spur delivers high-fidelity IP intelligence that strengthens authentication decisions, detects ATO patterns, and enables proportional defenses against anonymized login abuse.

Identify authentication traffic originating from VPNs, residential proxies, and other anonymizing services commonly used in credential-stuffing and account takeover campaigns.

Detect anonymized login attempts

Identify authentication traffic originating from VPNs, residential proxies, and other anonymizing services commonly used in credential-stuffing and account takeover campaigns.

Add context to network origin

Identify whether login attempts originate from VPNs, residential proxy networks, hosting providers, or shared anonymization infrastructure.

Strengthen authentication decisions

Use IP intelligence delivered via API or session enrichment to trigger step-up verification only when risk is elevated, reducing reliance on blanket MFA enforcement.

Detect distributed login abuse

Surface credential stuffing and password spraying by correlating IP reuse and proxy rotation across authentication events using real-time enrichment or on-prem data feeds.

Apply adaptive rate limiting

Adjust rate limits dynamically based on infrastructure risk rather than static thresholds that attackers easily evade.

Protect account recovery workflows

Flag recovery and support requests originating from anonymized infrastructure using consistent intelligence across live sessions and backend systems.

Reduce false positives without sacrificing coverage

Move beyond coarse IP reputation by correlating infrastructure attributes, behavioral anomalies, and technical fingerprints.

Financial Institution Reduces ATO By Over 40%

A financial institution reduced successful account takeovers by more than 40% by incorporating high-fidelity IP intelligence into its authentication workflows.

By identifying VPN- and proxy-backed login attempts and applying targeted controls, the institution disrupted ATO campaigns without increasing friction for legitimate users.
