SENTRY — Cybersecurity & Threat Management

24/7 SOC. AI observability.
Threat hunting that doesn’t sleep.
Detection in seconds, not days.

The active intelligence layer of your defense.

24/7 threat hunting and rapid incident response that neutralizes adversaries at the endpoint and in the cloud before they impact operations. Enterprise-grade SOC, AI-powered threat intelligence, and the only managed AI observability practice in the upper Midwest. Mean time to detect measured in seconds — because the adversary doesn’t wait for business hours.

Your organization is adopting AI whether you planned for it or not. SENTRY monitors threats traditional tools miss — shadow AI, prompt injection, model manipulation. As your managed intelligence provider, we close the observability gap between AI deployment and AI security.

Beyond Traditional Managed Security

Intelligence-Driven Cyber Defense

Traditional managed security providers monitor alerts. Armorstack eliminates threats. Our SENTRY portfolio delivers a fundamentally different approach — combining human-led threat hunting, AI-augmented detection, and automated response orchestration into a unified cyber defense operation. We don’t just watch your environment; we actively defend it, 24/7/365, with the same operational discipline used by nation-state defense organizations.

What Sets Us Apart

  • Proactive Threat Hunting — Our analysts actively hunt for adversaries in your environment, not just wait for alerts. We find threats that automated tools miss.
  • Unified Detection & Response — Single pane of glass across endpoint, network, cloud, and identity — eliminating the blind spots that multi-vendor stacks create.
  • Compliance-First Architecture — Every detection, response, and remediation action is documented to the evidentiary standard required by HIPAA, PCI DSS, CMMC, and SOC 2.
  • Vendor-Agnostic Integration — We work with your existing technology investments, not against them. No rip-and-replace required.

Operational Capabilities

  • Mean Time to Detect (MTTD) under 15 minutes
  • Automated containment and isolation protocols
  • Forensic-grade evidence preservation
  • Executive-ready incident reporting within 4 hours

“We don’t sell security products. We deliver security outcomes. Every engagement — domestic or international — is measured by threats eliminated, not alerts generated.”

AI Security

The Enterprise AI Security Gap

“The average breach costs $4.44M globally. Organizations using AI-powered security cut breach lifecycle by 80 days, saving $1.9M.”— IBM Cost of a Data Breach Report, 2025

Shadow AI, model drift, data poisoning, and prompt injection create attack vectors that traditional SIEM and EDR platforms fundamentally cannot detect. These tools were built for network packets, endpoint telemetry, and log correlation — not for monitoring the token streams, embedding spaces, and API trust boundaries that define modern AI infrastructure. Protecting LLMs and AI agents requires purpose-built AI observability platforms that understand the behavioral baseline of models and can identify deviations in real time, long before a breach becomes visible in conventional monitoring.

Armorstack’s SENTRY portfolio closes this gap as the active intelligence layer between your AI infrastructure and your security operations center. We bring the same 24/7 SOC discipline, behavioral analytics expertise, and threat hunting methodology that protects your endpoints and networks — applied to every AI model, API endpoint, and agentic workflow in your environment. The result is a unified AI and cyber security posture that eliminates the blind spots that attackers are actively exploiting today.

Threat Intelligence

AI Threat Vectors We Neutralize

Every AI deployment creates new attack surfaces. SENTRY monitors them all.

Prompt Injection Attacks

Adversarial inputs that manipulate LLM behavior to bypass controls, exfiltrate data, or execute unauthorized actions. SENTRY monitors all LLM input/output streams for injection patterns in real time.

Shadow AI & Ungoverned Models

Unauthorized AI tools deployed by business units outside IT governance, creating blind spots in your security posture. SENTRY discovers and inventories every AI asset across your environment.

Model Inversion & Data Extraction

Attacks that reverse-engineer training data from model outputs, exposing sensitive PII and proprietary information. SENTRY detects anomalous query patterns that indicate extraction attempts.

AI Supply Chain Compromise

Poisoned pre-trained models, compromised APIs, and malicious packages in the AI development pipeline. SENTRY validates model integrity and monitors API trust boundaries.

Model Drift & Behavioral Degradation

Production models that silently degrade in accuracy or develop biased outputs without detection. SENTRY provides continuous behavioral baselining and drift alerting.

RAG Poisoning & Knowledge Base Attacks

Manipulation of retrieval-augmented generation systems through corrupted knowledge bases and document injection. SENTRY monitors RAG pipelines for content integrity.

Our Methodology

Armorstack AI Security Framework

A structured, four-layer approach to enterprise AI security covering discovery, observability, risk governance, and adversarial testing.

AI Asset Discovery & Shadow AI Governance

The first step in AI security is knowing what you have. Armorstack SENTRY performs comprehensive AI asset discovery across your enterprise — identifying every deployed model, API integration, AI-powered SaaS application, embedded agent, and developer-deployed tool that exists in your environment. This discovery process reaches across cloud environments, SaaS platforms, internal development repositories, and end-user devices to surface the full breadth of your AI attack surface.

Once discovered, every AI asset is classified by risk tier, data sensitivity, and governance status. Armorstack establishes formal Shadow AI governance policies, maintains a living AI asset inventory, and enforces acceptable use policies for generative AI tools across your workforce. Business units that have deployed unauthorized AI tools are brought into a managed governance framework — eliminating blind spots without disrupting legitimate productivity use cases.

Continuous AI Observability

AI systems require a fundamentally different observability model than traditional applications. SENTRY deploys purpose-built AI observability tooling that monitors LLM input and output streams in real time, tracking token usage analytics, prompt pattern analysis, response anomaly detection, and latency deviations that may indicate adversarial interference or model degradation. Every interaction with your AI infrastructure is logged, scored, and correlated against established behavioral baselines.

Critically, SENTRY integrates AI telemetry directly into your existing SOC workflows and SIEM platforms — ensuring that AI-specific threat signals are correlated with traditional cybersecurity data rather than siloed in a separate tool. When a prompt injection attempt occurs alongside an unusual network connection, SENTRY’s integrated platform surfaces the correlated alert as a single incident, enabling faster investigation and response than disparate tooling allows.

AI Risk Management & NIST AI RMF Alignment

Armorstack maps every AI deployment in your environment to the NIST AI Risk Management Framework’s four core functions: Govern, Map, Measure, and Manage. The Govern function establishes organizational policies, roles, and accountability structures for AI risk. Map identifies AI use cases and their associated risk categories. Measure provides ongoing assessment of AI system performance, bias, and security posture. Manage implements risk responses and maintains continuous monitoring across the full AI lifecycle.

Beyond NIST AI RMF, SENTRY’s AI risk management practice addresses EU AI Act compliance readiness for organizations with European operations, generating the documentation, audit trails, and conformity assessments required for high-risk AI system deployment. Board-level AI risk reporting is delivered monthly — translating technical AI risk metrics into business impact language that enables executive decision-making and investor transparency.

AI Red Teaming & Penetration Testing

Armorstack conducts structured adversarial testing of AI systems using the same red teaming methodology applied to traditional infrastructure — adapted for the unique attack surface of LLMs, AI agents, and RAG systems. Our AI penetration testing engagements include prompt injection testing across all identified input vectors, jailbreak attempt cataloging, model extraction and inversion simulations, data poisoning exercises for training pipeline security, and supply chain compromise scenarios targeting model registries and API trust boundaries.

Every AI red team engagement concludes with a comprehensive findings report and actionable remediation roadmap. Unlike generic penetration testing reports, Armorstack’s AI security assessments provide prioritized findings mapped to NIST AI RMF risk categories, specific technical mitigations for each identified vulnerability, and a 90-day remediation roadmap with clear ownership assignments. Our team returns after remediation to validate that identified vulnerabilities have been fully addressed.
