Cybersecurity Consulting + 24/7 SOC Monitoring

Every Gridisys engagement is built on two pillars — strategic consulting to design the right controls, and managed SOC monitoring to keep them effective.

Cybersecurity Consulting

UK consulting engagements: risk assessment, security architecture, conditional access design, compliance (Cyber Essentials, UK GDPR, FCA PS21/3, NIS2), incident-response planning. Board-ready documentation, no jargon, no surprise invoices.

  • Risk assessment + security architecture review
  • Conditional access + Entra ID hardening design
  • Cyber Essentials / UK GDPR / FCA / NIS2 compliance support
  • Incident response planning + tabletop exercises
  • Vendor + supply-chain security assessment
  • Board / DPO reporting + evidence pack

Managed SOC Monitoring · 24/7

AI-augmented Security Operations Centre — continuous monitoring across Microsoft 365 / Entra ID, Defender, on-prem, and cloud. UK-based analysts, sub-hour triage on critical alerts. No long contract required.

  • 24/7 SIEM monitoring — Microsoft 365, Entra ID, Defender, Azure, on-prem logs
  • BEC + mailbox-compromise + OAuth grant abuse detection
  • Suspicious sign-in + conditional access drift alerting
  • Ransomware + lateral-movement detection from EDR + Defender
  • Sub-hour triage on critical alerts, monthly ops report
  • Optional + integrated with consulting engagements

Most engagements start with consulting (1-2 weeks), then SOC monitoring (ongoing ) keeps the controls effective.
