Threat Intelligence

Track nation-state actors, ransomware crews, and new CVEs before they become incidents.

Focus Areas

  • APT tracking & attribution
  • Dark web monitoring
  • IOC enrichment
  • Zero-day radar

Recommended Actions

  • Publish executive-ready threat briefs
  • Automate ingestion into SIEM/SOAR
  • Correlate TTPs with local telemetry

Network Security

Harden the perimeter, decrypt suspicious traffic, and detect lateral movement early.

Focus Areas

  • Next-gen firewall tuning
  • Secure access service edge
  • Encrypted traffic analysis
  • Zero Trust segmentation

Recommended Actions

  • Continuously validate firewall & ACL baselines
  • Map high-risk pathways
  • Instrument critical links with packet capture

Endpoint Security

Protect laptops, servers, and OT/IoT assets with proactive detection and response.

Focus Areas

  • EDR/XDR telemetry
  • Application allow-listing
  • Privileged access monitoring
  • Sensor tamper-proofing

Recommended Actions

  • Triage suspicious binaries in sandboxes
  • Correlate identity + endpoint alerts

  • Attack surface intelligence
  • Patch orchestration
  • SBOM governance

Recommended Actions

  • Align remediation with asset criticality
  • Use maintenance windows efficiently
  • Automate validation scans post-patch

Security Awareness

Build a human firewall with phishing resilience and just-in-time education.

Focus Areas

  • Adaptive phishing simulations
  • Role-based micro-learning
  • Insider risk reporting
  • Executive training tracks

Recommended Actions

  • Share fresh threat stories internally

Best Practices

Codified lessons learned from active cyber defense programs.

Adopt Zero Trust Iteratively

Start with identity, then workloads, then data micro-segmentation.

Instrument Everything

Telemetry without retention is noise—ensure normalized, queryable data lakes.

Measure Mean Time to Hardening

Track how fast mitigations ship after threat intel hits the desk.

Security Tools

Battle-tested platforms Detectum deploys in hybrid environments.

XDR Stack

Unified detection pipelines stitching EDR, NDR, and email telemetry.

IaC Security

Policy-as-code scanners that halt risky deployments pre-merge.

SOAR Automations

Response playbooks for phishing, malware cleanup, and access revocation.

Guides & Tutorials

Deep dives written by Detectum responders for practitioners.

Build a Purple Team Program
