Senior DLP Analyst

Who You’ll Work With

In this role, you will act as a central pillar of Arista’s security posture, collaborating closely with Legal and HR to navigate sensitive investigations and insider risk cases, while partnering with IT and Endpoint Engineering to manage policy deployments across macOS, Windows, and Linux. You’ll work alongside Software Engineering and R&D to deeply understand and protect their source code workflows, ensuring that DLP controls provide robust security without hindering innovation. Furthermore, you will sync with the SOC and Security Automation teams to integrate alerts into SIEM/SOAR platforms and provide Executive Leadership with high-level reporting on data-at-risk metrics and the overall maturity of the data protection program.

What You’ll Do

Key Responsibilities

Alert Monitoring & Incident Response

• Monitor and analyze DLP alerts across endpoint, browsers, SaaS, and AI applications to identify potential data exfiltration events, policy violations, and insider threats.
• Conduct real-time triage of security alerts, distinguishing between true positives and false positives using behavioral context, data lineage analysis, and sensitive findings.
• Perform detailed forensic investigations into data loss incidents, analyzing user activity, data movement patterns, and exfiltration vectors (email, web uploads, removable storage, source code exfiltration, GenAI apps, etc.).
• Coordinate incident response and escalation procedures, working closely with security leadership on high-severity cases.
• Document investigation findings, evidence trails, and remediation recommendations with clear, actionable reports.

Policy Development & Optimization

• Design, implement, and maintain enterprise DLP technology solutions across endpoints, servers, cloud, and network environments.
• Configure and maintain DLP policies based on Arista’s data classification schemes and compliance requirements (GDPR, HIPAA, PCI-DSS, SOX).
• Continuously tune detection rules and sensitivity thresholds to reduce false positives while maintaining high detection accuracy.
• Establish baselines for normal user behavior by role and department to improve anomaly detection and UEBA (User and Entity Behavior Analytics) efficacy.

Data Discovery & Platform Administration

• Lead data discovery and classification efforts using Arista’s DLP and EDR tools (e.g Crowdstrike Falcon, etc).
• Troubleshoot technical issues with endpoint agents, browser extensions, and SaaS integrations.

Reporting & Strategy

• Serve as a subject matter expert (SME) for Arista’s DLP tools and case management systems.
• Compile executive-level reports featuring key performance indicators: detection accuracy, mean time to respond (MTTR), and data-at-risk metrics.
• Stay informed about emerging insider threat trends and adversary tactics (TTPs) to inform program maturity.

Qualifications

• Minimum 5 years of experience in information security, with a primary focus on Data Loss Prevention (DLP), insider threat, or data protection.
• Technical Expertise: Deep hands-on experience with enterprise DLP and DSPM tools (e.g., Endpoint Protector, CyberHaven,etc.,) 
• Forensic Mindset: Proven ability to conduct complex investigations, analyze data movement, and interpret system logs.
• Data Governance: Strong understanding of data classification methodologies and sensitive data types (PII, PHI, PCI, IP, and source code).
• Compliance Knowledge: Familiarity with frameworks such as NIST CSF, GDPR, SOC2 Type 1 & II and PCI-DSS.
• Education: Bachelor’s degree in Cybersecurity, Computer Science, Information Security, or a related field.

Technical Proficiency

• Platforms: Deep understanding of endpoint security across macOS, Windows & Linux
• Cloud/SaaS: Knowledge of SaaS security and cloud architectures (O365, Google Workspace, Slack, GitHub, Box, Egnyte, Salesforce).
• Tools: Experience with SIEM platforms (Falcon SIEM, Sumologic or similar) and SOAR tools (Tines, Palo Alto XSOAR, or similar).
• Automation: Basic scripting skills or use of augmentation or any other platform for automating repetitive tasks and data analysis.
