SIGNAL

Trust & Safety Intelligence Layer

Complete threat visibility for messaging platforms—without reading a single message

Signal gives Trust & Safety teams the intelligence they need to detect coordinated phishing attacks, monitor campaign trends, and protect communities—all while preserving user privacy.

The Intelligence Layer Your Trust & Safety Team Need

Traditional account-layer security stops 99.5% of obvious threats—bots, mass spam, and fake accounts. But sophisticated attackers using hijacked trusted accounts, AI-generated lures, and polymorphic links slip through, causing the majority of high-value damage.

Signal closes this “last mile” security gap by analyzing URL threats in real-time across your entire messaging ecosystem—without ever reading message content.

Powered by Atrosec MasterDB, Signal provides comprehensive threat visibility through metadata-only analysis. Your users’ private conversations remain completely private while your Trust & Safety team gets the intelligence needed to detect coordinated campaigns, investigate threats, and protect your community.

Built specifically for messaging platforms, marketplaces, dating apps, social networks, and any platform with user-to-user or user-to-business messaging.

Signal protects 27+ messaging verticals including dating applications, online marketplaces, professional networking platforms, gaming communities, social commerce, gig economy platforms, and more.

Privacy-First

Metadata-only analysis. Never reads message content. GDPR compliant by design. Legally defensible approach.

Campaign Correlation

Connect isolated messages to detect coordinated attacks. See patterns invisible to per-message filtering.

Actionable Intelligence

Real-time alerts, investigation tools, and explainable evidence. Empower your T&S team with context, not just blocks.

Close the Last Mile Security Gap

Signal solves the critical problems that traditional security misses when attackers move at link-speed and enforcement moves at human-speed.

The 99.5% Paradox

THE PROBLEM: Your automated security blocks 99.5% of threats—bots, mass spam, obvious fakes. But the remaining 0.5% of "architect" attackers cause the majority of high-value damage.

These sophisticated attackers use:

  • Hijacked verified/trusted accounts
  • AI-generated personalized lures (54% CTR)
  • Polymorphic links that change behavior
  • Time-bomb URLs that "flip" from safe to malicious

By the time your team investigates, the damage is done.

HOW SIGNAL SOLVES IT: Real-time URL intelligence detects sophisticated threats at the moment of sending. Visual AI catches what account-layer security misses. Zero-hour detection stops attacks before they're reported or blacklisted.

RESULT: Catch the 0.5% that matters most.

Reactive Enforcement

THE PROBLEM: Traditional approach: User clicks → damage done → user reports → investigation → enforcement (254 days average detection time).
Attackers move at link-speed. Your team moves at human-speed. The median time-to-click is <60 seconds—faster than any manual review cycle.
You're stuck in endless "whack-a-mole" cycles, reacting only after user harm has occurred.

HOW GUARD SOLVES IT: Proactive intelligence layer provides real-time risk signals at the moment URLs are sent. Alerts flag suspicious activity before mass user harm. Campaign correlation reveals coordinated attacks in progress.

RESULT: Shift from reactive cleanup to proactive prevention.

Visibility Blindness

THE PROBLEM: Your T&S team is flying blind. Traditional security blocks threats silently or provides no context for investigations. You can't see:

  • Campaign patterns across users
  • Attack sophistication trends
  • Risk distribution by geography/vertical
  • Repeat offenders or coordinated groups

Without visibility, you can't prioritize, investigate effectively, or measure risk trends.

HOW GUARD SOLVES IT: Comprehensive dashboard with campaign aggregation, user timelines, risk trends, and explainable evidence. See the forest AND the trees. Understand what's happening across your platform in real-time.

RESULT: Informed decisions with full context.

Privacy vs. Security Trade-off

THE PROBLEM: Effective threat detection seems to require reading message content—but that violates user privacy, triggers GDPR concerns, and damages user trust.
You're forced to choose: protect privacy OR protect users from threats.

HOW GUARD SOLVES IT: Metadata-only architecture analyzes URL threats without accessing message content. We never see what users write—only technical signals about the links they share.
Privacy-first approach is GDPR compliant, legally defensible, and maintains user trust while delivering superior threat detection.

RESULT: Security AND privacy—no compromise required.

Complete Trust & Safety Intelligence Platform

Powered by Atrosec MasterDB, Signal provides the tools your Trust & Safety team needs to detect, investigate, and respond to URL-based threats across your messaging ecosystem.

Real-Time Threat Detection

WHAT IT DOES: Analyzes every URL shared across your platform in real-time with <50ms response time. Returns risk score (0-7), verdict (clean/suspicious/malicious), and explainable indicators.

KEY FEATURES:

  • Zero-hour detection (catches threats before blacklists)
  • Visual AI identifies fake logos and credential forms
  • Polymorphic link detection (catches behavior changes)
  • Redirect chain analysis (traces obfuscation)

YOUR BENEFIT: Stop sophisticated attacks at the moment of sending, not days later after user reports.

Campaign Correlation

WHAT IT DOES: Connects isolated message events to reveal coordinated phishing campaigns. Identifies patterns across users, time periods, and attack vectors.

KEY FEATURES:

  • Cross-user pattern detection
  • Temporal clustering (attacks in waves)
  • Domain/infrastructure fingerprinting
  • Attacker group profiling

YOUR BENEFIT: See coordinated attacks that are invisible to per-message filtering. Contain campaigns before they spread.

Investigation Dashboard

WHAT IT DOES: Comprehensive interface for Trust & Safety analysts to investigate threats, review timelines, and understand attack context.

KEY FEATURES:

  • User timeline view (all URL activity)
  • Campaign detail pages with evidence
  • Risk trend visualization over time
  • Searchable threat database
  • Export capabilities for legal/policy review

YOUR BENEFIT: Faster investigations with full context. Make informed enforcement decisions backed by evidence.
