Threat Hunting Services UK
Proactive threat hunting for UK SMEs — weekly hunts for IOCs, TTPs, and emerging threats relevant to UK businesses. We find the threats your automated detection misses: dormant attackers, living-off-the-land, and slow-burn compromises.

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

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.

What we cover
Practical, board-ready consulting — no jargon, no surprise invoices.
Weekly Threat Hunts
Proactive searches across your Microsoft 365, Entra ID, Defender, and on-prem logs for IOCs and TTPs — using MITRE ATT&CK techniques relevant to UK businesses.
IOC Sweeps
We sweep your environment for indicators of compromise — known malicious IPs, domains, file hashes, and OAuth apps — from NCSC, CISA, and commercial threat intel.
Living-off-the-Land Detection
We hunt for attackers using legitimate tools (PowerShell, WMI, net.exe) to blend in — the top technique used by Scattered Spider and BEC groups.
Dormant Attacker Detection
We look for accounts created and left dormant, mailbox rules forwarding externally, and OAuth grants that haven't been used — signs of a planted backdoor.
Threat Intelligence Integration
We integrate UK-relevant threat intel (NCSC, Action Fraud, commercial feeds) so your environment is checked against emerging IOCs automatically.
Hunt Reports
Each hunt produces a report: hypotheses tested, findings, IOCs checked, and recommendations. Monthly summary for the board.
How we work
Hypothesis development
We develop hunt hypotheses based on current UK threat intelligence — e.g. 'Is Scattered Spider targeting our Entra ID guest users?'
Weekly hunt
We query your logs and EDR telemetry against the hypothesis, checking for TTPs and IOCs.
Findings + response
If we find a threat, we escalate immediately with containment guidance. If clean, we document and move to the next hypothesis.
