Proofpoint / ArcXA - acts as the sensor and shield

Proofpoint acts as the sensor and shield for your communications, while Equitus ArcXA acts as the brain that connects those signals to the rest of your world to provide total situational awareness.

ACS Proposes:  Equitus.ai ArcXA (a Knowledge Graph Neural Network or KGNN platform) and Proofpoint can work together by bridging the gap between "siloed" email/communication data and "enterprise-wide" relationship intelligence.

While Proofpoint is exceptional at stopping threats at the perimeter (email, cloud, and web), Equitus ArcXA excels at connecting that threat data to the broader context of your organization’s physical and digital assets.

1. Advanced Insider Threat Intelligence

Proofpoint identifies "Very Attacked People" (VAPs) and risky behaviors like data exfiltration. However, it often lacks the context of what those people do outside of their email.

• The Workflow: Proofpoint feeds telemetry (unusual logins, sensitive file attachments, or DLP alerts) into ArcXA.

• The Result: ArcXA links that email data to other sources—such as physical badge access logs, HR records, or financial transactions. If a VAP suddenly accesses a secure server room at 2:00 AM after sending an encrypted email (flagged by Proofpoint), ArcXA’s graph intelligence identifies this as a high-priority "multimodal" threat that a single tool would miss.

2. "Agentic" Security and AI Governance

As of 2026, Proofpoint has introduced AI Security to govern how human and AI agents interact. ArcXA can act as the "Source of Truth" for these interactions.

• The Workflow: Proofpoint monitors AI agent prompts and responses for data leakage or "agentic privilege escalation."

• The Result: ArcXA ingests these interaction logs to map the lineage of data. It can show exactly how an AI agent’s action in Proofpoint connects back to a specific database or a downstream business process, providing the "Explainable AI" (XAI) needed for compliance and auditing.

3. Automated Incident Reconstruction

When a phishing attack succeeds, SOC teams usually spend hours manually piecing together what happened.

• The Workflow: ArcXA automatically ingests Proofpoint’s "TAP" (Targeted Attack Protection) alerts.

• The Result: Instead of looking at a list of 50 disconnected alerts, an analyst sees a Visual Knowledge Graph. ArcXA shows the "Patient Zero" email from Proofpoint, the lateral movement across the network, and the specific entities (servers, files, people) affected, reducing investigation time from hours to minutes.

4. Supply Chain Risk Mapping

Proofpoint can identify emails coming from "lookalike" domains or compromised vendor accounts.

• The Workflow: ArcXA takes these vendor threat signals and maps them against your organization's actual supply chain hierarchy.

• The Result: If Proofpoint flags a suspicious invoice from a vendor, ArcXA can instantly show you every department that uses that vendor, every contract they hold, and every system they have access to, allowing for a targeted, proactive lockdown.
