Cyber Security for Insurance Brokers — UK Intermediaries & MGAs
UK insurance brokers are FCA-regulated firms handling policy data, premium receipts, and (for life/health) customers' health information. Most now require FCA PS21/3 operational resilience evidence. We deliver SMCR-aligned managed SOC, premium BEC prevention, and the ICO + FCA notification playbooks your COLP needs at 2am.

What we cover
Practical, board-ready consulting — no jargon, no surprise invoices.
Managed SOC for M365 / Entra
24/7 monitoring of broker staff sign-ins, mailbox rules targeting premium instructions, OAuth grants on Acturis / Epic / Open GI integrations, superuser access to insurer portals. Surfaces the patterns of premium BEC before invoices are paid to fraudster accounts.
FCA PS21/3 operational resilience evidence
Document IBS register, impact tolerances, severe-but-plausible cyber scenario tests, governance sign-off, and the SUP 17 reporting framework. Audit-ready evidence aligned to SYSC 13.9 and the PS21/3 Annex mapping.
SMCR accountability mapping
Personal accountability under SMCR (Senior Managers & Certification Regime) for security failures is now real. We allocate controls to SMR individuals, document the evidence pack for FCA information requests, and define the MLRO / COLP escalation path.
ICOBS + CASS compliance evidence
Where you hold client money (CASS 5), technical controls matter: MFA on bank portal, segregated access for finance staff, payment-authorisation lists. ICOBS 5.2 / insurance conduct rules evidence pack ready for FCA-OI inspection.
Premium BEC & claims fraud prevention
Specific controls against the major insurance broker BEC pattern: insurer-impersonation emails requesting broker commission refunds; client-impersonation instructing mid-term policy changes; claims correspondence interception.
Life/health policy special category data
Where you handle health, life, or critical-illness insurance, you process Article 9 special category data. We design explicit consent capture, restricted-IPM mailboxes, encryption at rest, retention limits, separate Theta-off process for renewals not taken up.
How we work
Scoping (Week 1)
Confirm FCA permissions, classes of business, client money arrangements, MGA / reinsurer integrations, current M365 / Entra posture.
Deploy (Week 1-2)
Connect M365 / Entra to Gridisys SOC. Configure conditional access: MFA, conditional sign-in by client jurisdiction, broker-portal admin access restricted to verified devices.
Evidence build (Week 2-3)
PS21/3 IBS register + impact tolerances + scenario tests. SMCR accountability allocation. ICOBS / CASS 5 technical controls evidence pack.
Operate (ongoing)
24/7 monitoring + monthly partner / MLRO reporting + quarterly resilience review + on-call for FCA / ICO breach coordination.
