AI Shield for Healthcare — £10M Attack Averted

AI Shield for Healthcare — £10M Attack Averted

Written by:Team Anglara
Published:August 10, 2025

AI correlates logs, user behavior, and endpoints to stop attacks before downtime.

Project Overview

A multi-facility healthcare provider needed to detect advanced threats early without slowing clinicians. We built an AI-assisted security layer that ingests telemetry from endpoints, firewalls, EHR access logs, and identity systems, then flags risky behavior in real time. Automated playbooks isolate compromised devices and revoke tokens within minutes. The system stopped an attack path that would have exposed critical systems and halted operations—averting losses estimated at up to £10M.

The Challenge & Solutions

Challenges

challenge-cards-icon

Fragmented Security Signals

Alerts were siloed across tools, making correlations and root-cause analysis slow.

challenge-cards-icon

Lateral Movement & Privilege Escalation

Traditional rules missed low-and-slow behavior across sites and vendors.

challenge-cards-icon

Clinical Workflow Sensitivity

Security controls couldn’t create friction for clinicians or impact uptime.

challenge-cards-icon

Audit & Compliance Pressure

Leadership needed provable controls, auditability, and evidence trails.

Solutions

challenge-cards-icon

Unified Telemetry & Correlation

Streaming ingestion of logs with AI models to detect anomalies and risky sequences.

challenge-cards-icon

Behavior Analytics & Zero-Trust Policies

UEBA to spot privilege misuse; just-in-time access and automatic token revocation.

challenge-cards-icon

Automated Response Playbooks

Isolate endpoints, disable accounts, and notify SOC—minutes, not hours.

Audit-Ready Evidence

Signed logs, immutable trails, and mapped controls for regulators and insurers.

Process

1. Define

Threat model, assets, and acceptable automated actions.

2. Instrument

Connect endpoints, firewalls, identity, and app logs to the pipeline.

3. Validate

Run in shadow mode; tune signals and thresholds.

4. Automate

Enable playbooks; rehearse drills with SOC and IT.

5. Operate

24×7 monitoring dashboards and weekly hygiene reports.

6. Iterate

New detections based on post-incident reviews.

Product Specs / Tech Stack

  • Scope: AI-assisted threat detection and automated response
  • Tech Stack: NDA-safe/varies by client
  • Safeguards: RBAC, least-privilege, encryption, and immutable logs

Key Trends and Innovations

Explainable Alerts

Human-readable reasons for each alert increase trust and reduce alert fatigue in the SOC.

Risk Scoring Per Identity/Device

Focuses teams on the highest-impact threats and shortens time-to-contain.

Safe-Mode Rollout

Shadow mode for two weeks validated signal quality before automated actions went live.

Book a security assessment to map threats across your estate.

Let’s Talk

The Impact

Blocked a high-impact attack path

loss exposure estimated up to £10M.

Faster containment

minutes to isolate endpoints and revoke tokens.

Lower alert fatigue

explainable signals increased SOC confidence.

Zero clinician friction

no change to EHR workflows during rollout.

How Anglara can transform your company?

Enterprise-wide threat detection

Correlate endpoint, network, identity, and EHR logs to surface real attacks fast.

Automated containment

Playbooks isolate devices, revoke tokens, and notify ops in minutes—no clinician friction.

Continuous compliance evidence

Immutable audit trails, mapped controls, and weekly hygiene reports.

Executive-ready risk reporting

Clear KPIs—MTTD/MTTR and incidents avoided—for boards and insurers.

Conclusion

Healthcare needs strong security without slowing care. By unifying signals and automating safe responses, we prevented a costly incident and gave leadership defensible assurance.
