What we cover
Practical, board-ready consulting — no jargon, no surprise invoices.
Managed SOC for M365 / Entra
24/7 AI-powered monitoring of every sign-in, privilege escalation, and impossible-travel pattern across your Microsoft 365 / Entra ID. Surfaces BEC, mailbox takeover, and admin account compromise in real time.
FCA operational resilience evidence
We help you build the PS21/3 evidence pack: IBS mapping, impact tolerances, severe-but-plausible cyber scenario testing, governance sign-off. Audit-ready and demonstrably aligned to SYSC.
SMCR accountability mapping
Personal accountability under SMCR is real for security failures. We document which SMR individual owns which control, sign-off evidence pack for the FCA's regs officer request, and the escalation path.
Client data protection
Article 32 technical and organisational measures — encryption, MFA, conditional access, data minimisation, retention. We evidence these in a DPO-ready format for the inevitable ad-hoc FCA information request.
BEC & client money fraud prevention
Targeted at wealth managers and IFAs: protect against supplier bank-change requests, director impersonation, and fraudulent client fund instructions. Includes supplier-callback verification process.
ICO breach decision & filing
If you're breached, the clock starts immediately. Triage + Article 33 decision + ICO submission drafting inside the 72-hour window — coordinated with FCA notification under DISP SUP 15A where relevant.
How we work
Scoping (Week 1)
Confirm FCA permissions held, IBS list, current M365 / Entra posture, ongoing DPIA gaps. Map SMCR accountability for security outcomes.
Deploy (Week 1-2)
Connect Microsoft 365 / Entra to Gridisys SOC. Configure conditional access baselines: MFA everywhere, block legacy auth, restrict admin to compliant devices, geo-fencing by client country.
Evidence build (Week 2-3)
Article 32 technical measures pack. PS21/3 IBS register + impact tolerances + scenario tests. Ready for ICO / FCA information requests.
Operate (ongoing)
24/7 monitoring + monthly executive reporting + quarterly resilience review. On-call for incidents within the FCA SUP 17 context.
