Your AttackSOC™ Analyst
Your dedicated AttackSOC analyst serves as your primary point of contact, owning the relationship, managing escalations, and ensuring your leadership stays informed at every stage of the engagement.
Onboarding & Deployment - Before a single agent deploys, your analyst conducts a structured scoping session to map your endpoint environment, document your data sources, define ingestion priorities, and configure the platform to your specific environment and obligations.
Alert Triage & Interpretation - Your analyst reviews detections, separates real threats from false positives, and delivers clear, actionable guidance so your team responds to what matters, not everything the SIEM surfaces.
Adversary-Mindset Hunting - Your analyst actively hunts for attacker behavior across your environment, tracking indicators of compromise, lateral movement, and privilege escalation before damage is done, rather than waiting for an automated alert to fire.
Framework & Compliance Alignment - Whether your obligation is NIST CSF, ISO 27001, CIS Controls, CMMC, or HIPAA, your analyst ensures PrismX detections and reporting map to the frameworks that govern your business.
Ongoing Security Advisory -Your analyst meets with your team regularly to review detection trends, advise on environment hardening, brief leadership on the current threat landscape, and ensure your defenses keep pace with attacker behavior.

Endpoint Deployment & SIEM Onboarding
PrismX begins with a structured onboarding process that deploys lightweight endpoint agents across your managed device fleet and connects your environment's log sources to the Guardian SIEM. Already running a SIEM? PrismX can ingest its feeds, or sit in front of it, resolving the noise it can address and passing the rest to your SIEM or ticketing system. Before any hunting begins, your AttackSOC analyst configures detection logic, ingestion pipelines, and alerting thresholds to your specific environment, not a generic out-of-the-box template.
Endpoint Agent Deployment - Lightweight PrismX agents are deployed across your managed endpoints (servers, workstations, and laptops), providing continuous telemetry on process activity, file system changes, network connections, and user behavior.
SIEM Data Ingestion - Log sources across your environment, including identity providers, firewalls, cloud platforms, email security, and endpoint telemetry, are connected to the Guardian SIEM directly or through your existing SIEM, then normalized and correlated in a single unified data plane.
Detection Rule Configuration - Your AttackSOC analyst configures and tunes detection rules, correlation logic, and alerting thresholds to your environment, reducing false positive noise and ensuring the signal that reaches analysts is relevant and actionable.
Baseline Establishment - PrismX establishes behavioral baselines across your endpoint fleet and ingested data sources, enabling anomaly detection that is calibrated to how your specific environment operates, not a population average.
Your AttackSOC™ analyst conducts regular program reviews with your leadership, presenting detection trends, vulnerability posture, hunt activity, and remediation progress in business terms that keep your executives informed and your security program on track.

Internal & External Vulnerability Assessment
PrismX runs continuous vulnerability assessments across both your internal endpoint estate and your externally exposed infrastructure. Every finding is enriched with real-time threat intelligence and prioritized by exploitability, so your team always knows which vulnerabilities represent the greatest actual risk to your business.
Internal Vulnerability Scanning - Continuous agent-based scanning identifies unpatched software, misconfigurations, insecure services, and policy violations across your managed endpoint fleet, with findings mapped to CVE severity and business impact.
External Vulnerability Assessment - PrismX scans your externally exposed infrastructure (internet-facing systems, services, and hosts) to find vulnerabilities exploitable from outside your perimeter before an attacker does.
CVE & KEV Enrichment - Every vulnerability finding is correlated against the CVE database and CISA's Known Exploited Vulnerabilities (KEV) catalog, ensuring prioritization reflects which exposures are actively being weaponized in the wild.
Automated Remediation Verification - Once a remediation action is taken, PrismX automatically validates that the fix was effective, eliminating manual spot-checks and ensuring no exposure lingers past its remediation deadline.
Your AttackSOC analyst reviews all critical and high-severity vulnerability findings with your team, distinguishing exploitable exposures from lower-priority items, advising on remediation sequencing, and ensuring your organization addresses what matters most first.

SIEM-Powered Threat Detection
The Guardian SIEM continuously ingests, normalizes, and correlates telemetry from across your environment - endpoint agents, identity systems, network devices, cloud platforms, and more. Advanced correlation rules and AI-driven anomaly detection surface genuine threats from the volume of daily security events, giving your AttackSOC the signal fidelity needed to hunt effectively.
Cross-Source Event Correlation - The SIEM correlates events across every connected data source, matching endpoint telemetry against identity logs, network traffic, and cloud activity to detect multi-stage attack patterns that no single source would reveal alone.
AI-Driven Anomaly Detection - Machine learning models trained on your environment's behavioral baselines identify deviations that rule-based detection misses, surfacing subtle signs of compromise, such as unusual logins, abnormal process behavior, or unexpected data movement.
Threat Intelligence Integration - Detection logic is continuously enriched with current threat intelligence feeds, MITRE ATT&CK TTP mappings, and indicators of compromise, ensuring the SIEM detects attacker behavior as it evolves, not as it was documented last year.
Alert Prioritization & Noise Reduction - PrismX's correlation engine scores and prioritizes alerts by confirmed risk, suppressing known-good behavior and surfacing only the detections that require human judgment.
Your AttackSOC analyst monitors SIEM detection outputs on your behalf, triaging alerts, investigating correlated events, separating genuine threats from false positives, and escalating confirmed detections to your team with full context and recommended response actions.

Hunter-Led AttackSOC™ Threat Hunting
Traditional SOCs are reactive by design. They monitor dashboards, triage alerts, and investigate incidents after damage is done. Guardian's AttackSOC operates differently. The analysts think like adversaries, actively hunting for attacker behavior across your endpoint telemetry and SIEM data, identifying threats in the early stages of the kill chain before they escalate.
Proactive Threat Hunting - AttackSOC analysts conduct structured hunts across your endpoint telemetry and SIEM data, searching for indicators of attacker behavior, anomalous activity, and early-stage intrusion patterns that automated detection does not surface.
Kill Chain Analysis - When a threat is identified, analysts trace it across the MITRE ATT&CK framework, mapping initial access, execution, persistence, lateral movement, and exfiltration activity to understand the complete scope of the threat.
Hypothesis-Driven Investigation - Hunts are structured around threat hypotheses informed by current intelligence, targeting the specific tactics, techniques, and procedures most relevant to your industry and the threat actors most likely to target your organization.
Zero-Trust Risk Identification - AttackSOC analysts identify trust relationships and access patterns that represent risk, flagging overprivileged accounts, anomalous authentication activity, and lateral movement paths for immediate remediation.
Your AttackSOC analyst leads active threat hunts across your endpoint and SIEM environment, pursuing threat hypotheses, tracing attacker activity through the kill chain, and escalating confirmed threats to your team with a clear incident summary and response guidance.

Response, Containment & Remediation
When the AttackSOC confirms a threat, PrismX moves immediately to contain and remediate. Response playbooks execute containment actions in real time, isolating endpoints, blocking connections, and revoking credentials while your analyst coordinates the full incident response and ensures your environment is hardened against repeat attacks.
Automated Endpoint Containment - Confirmed threats trigger automated containment actions at the endpoint level, isolating affected hosts from the network, terminating malicious processes, and preserving forensic state for investigation. Which actions run automatically is agreed with you up front, so containment moves at the machine speed within the boundaries you’ve approved.
Credential & Access Response - Compromised or anomalous credentials trigger immediate response actions (account suspension, session termination, and forced re-authentication) to cut off an attacker’s ability to move deeper or gain higher access from their initial foothold.
Analyst-Led Incident Coordination - Your AttackSOC analyst leads the incident response process, briefing your leadership, advising on remediation priorities, documenting the full incident timeline, and coordinating any required escalation to your internal teams or legal counsel.
Post-Incident Hardening - Every confirmed incident drives a structured post-incident review. Your analyst identifies root cause, maps the attack path, and produces hardening recommendations that reduce the likelihood of a repeat intrusion via the same vector.
Your AttackSOC analyst leads incident response from detection through resolution, coordinating containment, briefing leadership, documenting the full incident record, and delivering a post-incident hardening plan your team can act on immediately.

Reporting, Visibility & Compliance Documentation
PrismX provides continuous, real-time visibility into your security posture, detection activity, vulnerability status, and remediation progress. Leadership always knows where you stand, and you can produce regulator-ready and underwriter-ready reports on demand without a manual scramble.
Real-Time Security Operations Dashboard - An always-current dashboard delivers leadership-level visibility into endpoint coverage, active detections, open vulnerabilities, hunt activity, remediation velocity, and overall security posture in one place.
Compliance Evidence Collection - PrismX continuously tracks and stores evidence of security controls, detection events, and remediation actions, making audit preparation and regulatory reporting a structured, repeatable process rather than a last-minute effort.
Cyber Underwriting Reporting - Pre-formatted reports aligned to cyber insurance underwriter requirements document your endpoint coverage, detection capability, and incident response maturity, supporting favorable policy terms, renewals, and coverage decisions.
Executive & Board Reporting - Plain-language, visual summary reports translate detection data and vulnerability findings into business-relevant risk narratives suitable for board presentation, executive briefing, or regulatory submission.
Your AttackSOC analyst leads onboarding from scoping through go-live, confirming every endpoint is covered, every priority data source is connected, and every detection rule is tuned to your environment before active hunting begins.
