Senior Support Specialist (Security & Network)

Securonix is leading the transformation of cybersecurity by helping organizations stay ahead of modern threats. Security teams are no longer constrained by data or tools. They are constrained by speed, clarity, and confidence. Securonix was built to close that gap. Our mission is to enable security teams to decide and act faster across the entire threat lifecycle.
The Securonix Unified Defense SIEM is the industry’s first platform powered by agentic AI and designed with a human-in-the-loop philosophy. It unifies detection, investigation, and response in a single system. Advanced UEBA delivers deep behavioral insight across users, entities, and data. Native threat intelligence continuously enriches detections and investigations with real-world context. AI reinforces every layer of the platform while keeping accountability with the security team.
Built cloud-native for scale and performance, the platform enables real-time analytics, deep investigation, and automated response without compromise. Analysts gain faster access to relevant signals. Investigations move from days to minutes. Response becomes consistent and measurable. The result is a CyberOps experience that scales as threats evolve.
Securonix is recognized as a six-time Leader in the Gartner Magic Quadrant for SIEM and a Customers’ Choice on Gartner Peer Insights. The company has been featured by leading publications including WIRED, Dark Reading, and Fortune for its innovation and leadership in security operations. Organizations rely on the platform for always-available data, rapid search and investigation, continuously updated threat content, and a fully integrated Threat Detection, Investigation, and Response experience.
Backed by Vista Equity Partners, one of the world’s leading enterprise software investors, Securonix benefits from deep operational expertise and a long-term commitment to innovation and growth. This partnership strengthens our ability to scale the platform, accelerate product execution, and support customers as their security needs evolve.

Role Summary:
The Senior Support Specialist is a senior security practitioner responsible for defending the organization’s network, infrastructure, and cloud environments against internal and external threats. This role operates at the intersection of security engineering and operations, with direct ownership of network security controls, threat detection, and incident response. Support responsibilities exist to enable security outcomes, not as an end in themselves.
This position requires hands-on expertise, sound judgment under pressure, and the ability to identify systemic risk before it becomes an incident.
Core Responsibilities:
Network Security Ownership
Architect, deploy, and continuously harden network security controls including firewalls, VPNs, IDS/IPS, segmentation, and zero-trust access models.
Own network perimeter and internal trust boundaries, including firewall policy design, rule lifecycle management, and access validation.
Actively monitor network traffic and telemetry to identify indicators of compromise, lateral movement, and policy violations.
Lead vulnerability discovery and remediation for network and infrastructure components.
Threat Detection & Incident Response
Serve as the primary escalation point for all security incidents involving network intrusion, unauthorized access, malware, or data exposure.
Perform deep forensic analysis using logs, packet captures, and endpoint data to determine scope and impact.
Contain, eradicate, and recover from incidents while preserving evidence and maintaining operational continuity.
Drive post-incident root cause analysis and ensure corrective controls are implemented, not merely documented.
Security Operations Engineering
Maintain and tune security tooling including SIEM, NDR, EDR/XDR, and vulnerability management platforms.
Define detection logic, alert thresholds, and response playbooks aligned to real threat models rather than checkbox compliance.
Reduce noise and false positives while improving time-to-detect and time-to-contain metrics.
Security-Driven Support & Escalation
Handle only the most complex escalations where security risk, system integrity, or availability is at stake.
Enforce secure configuration standards across systems, networks, and cloud services.
Mentor support and IT staff on secure operational practices and adversarial thinking.
Risk, Governance & Assurance
Translate security policy and control requirements into enforceable technical reality.
