About the Job

Requirements

  • At least 6 years of cybersecurity experience, including substantial time responding to real intrusions rather than only monitoring for them.
  • Direct experience leading security incidents by setting direction and coordinating execution, rather than merely participating on an incident response team.
  • Experience responding across multiple distinct organizations, such as in consulting, managed security service provider, managed detection and response, or panel digital forensics and incident response settings.
  • Hands-on investigative experience in Microsoft 365, Google Workspace, and Entra ID compromise, including unified audit log analysis, message trace, mailbox rules and forwarding, OAuth consent and application grants, device code and token abuse, and conditional access gaps.
  • Working command of endpoint detection and response tools for investigation and containment, and sufficient host and Windows internals knowledge to interpret process lineage, persistence mechanisms, and lateral movement evidence.
  • Ability to build defensible incident timelines from mixed and incomplete sources, including security information and event management and detection alerts, endpoint telemetry, cloud audit logs, firewall logs, and help desk tickets.
  • Practical understanding of ransomware and hands-on-keyboard intrusion tradecraft sufficient to scope incidents and recognize when they exceed Harbor’s handling scope.
  • Demonstrated experience working alongside breach counsel, cyber insurance carriers, or third-party digital forensics and incident response firms during live incidents, including handing off investigations.
  • Ability to brief non-technical executives under pressure and write clear documents clients can act on without follow-up.
  • Willingness and ability to be reachable outside business hours for incident escalation.

Responsibilities

  • Serve as incident commander for client security incidents by establishing scope, setting response priorities, assigning actions to named owners, tracking decisions, and keeping the incident moving when the environment is unfamiliar and data is incomplete.
  • Run triage and initial investigation across Harbor-managed environments, including Microsoft 365 and Entra ID, Active Directory, endpoints under endpoint detection and response, servers, firewalls, and the Sagan-based detection pipeline and its alert history; delegate information gathering to internal resources as appropriate.
  • Own containment decisions and their consequences, including what is isolated, which credentials are reset, what remains running to preserve evidence, and which client stakeholders have authority to approve each action.
  • Make and defend escalation decisions; own in-scope incidents from detection through post-incident reporting, including business email compromise, single-host malware, and bounded credential compromise.
  • Brief receiving digital forensics and incident response firms when incidents exceed Harbor’s scope, and hand off with a written timeline and evidence inventory.
  • Carry on-call responsibility and remain available outside business hours for incidents.
  • Translate technical findings into actionable decisions for client owners, executives, and general counsel without overstating certainty or obscuring findings with jargon.
  • Coordinate with breach counsel, cyber insurance carriers and their panel firms, third-party digital forensics and incident response teams, client internal IT, and law enforcement where applicable; keep Client Success and leadership current on active incidents.
  • Produce post-incident reports covering what happened, what was confirmed versus assumed, what was contained, what remains open, and what the client should change.
  • Write and maintain incident response playbooks, a severity model, and an escalation matrix; define in writing where Harbor’s responsibility begins and ends so the boundary is clear in contracts and under pressure.
  • Build working relationships with outside digital forensics and incident response firms and breach counsel practices to support effective handoffs.
  • Maintain an escalation-readiness record for every managed client, including incident response retainers, cyber insurance and carrier details, named counsel, and clients without these resources.
  • When applicable and feasible, run tabletop exercises with Harbor teams and clients, and convert exercise findings into playbook changes.
  • Mentor security operations center analysts and security engineers on investigative methods and incident discipline, and feed lessons from real incidents to detection engineering to improve earlier detection.

Desired Qualifications

  • GCIH, GCFA, GCIA, or comparable GIAC certification; CISSP or CISM.
  • Prior experience at a panel digital forensics and incident response firm, managed detection and response provider, or managed security service provider incident response team.
  • Host and memory forensics depth, malware triage, or reverse engineering.
  • Linux investigation experience and cloud incident response beyond Microsoft, such as AWS or Google Workspace.
  • Familiarity with regulatory and contractual notification obligations under HIPAA, PCI DSS, GLBA, state breach notification statutes, or SEC disclosure rules.
  • Background in managed services or another multi-tenant environment where the candidate owned the client relationship as well as the investigation.
