Targeted attacks need targeted detection. AI that knows the difference.
Spear phishing attacks are researched, personalised, and designed to bypass standard filters. IP Four deploys AI behavioural analysis, OSINT correlation, and VIP-level scrutiny to detect targeted attacks that generic tools miss entirely.
Detection built for attacks that know your organisation.
Spear phishing bypasses generic filters because it looks legitimate. Our AI models understand context, behaviour, and intent to catch what others miss.
Contextual Content Analysis
AI models analyse the full context of every inbound message, not just headers and links. Unusual requests, urgency language, and out-of-character communication patterns are flagged in real time.
VIP and Privileged User Protection
Executives, finance staff, HR, and IT administrators receive enhanced scrutiny. Emails targeting these roles are subject to additional AI analysis layers before delivery.
Open Source Intelligence Correlation
Spear phishing attacks use publicly available information about targets. Our system correlates email content against known OSINT sources to identify when attackers have researched your staff.
Behavioural Baseline Modelling
Normal communication patterns for each user are modelled over time. Emails that deviate significantly from established patterns for a sender or recipient are flagged for review.
Zero-Day Spear Phishing Detection
Novel spear phishing attacks with no known signatures are detected through AI behavioural analysis. No reliance on signature databases means new attack variants are caught from day one.
Forensic Attack Investigation
When a spear phishing attempt is detected, full forensic detail is captured including sender infrastructure, payload analysis, and attack timeline. Supports incident response and law enforcement referral.
From target profiling to continuous detection.
Target Profile Mapping
We identify your highest-risk staff including executives, finance, HR, and IT administrators. Individual communication profiles are built to establish behavioural baselines for each target.
AI Model Calibration
Detection models are calibrated against your organisation's specific communication patterns, sector context, and known threat actors. Generic models are replaced with organisation-specific intelligence.
Enhanced Scrutiny Deployment
VIP and privileged user mailboxes receive additional detection layers. Inbound emails to these accounts are subject to deeper content analysis, OSINT correlation, and behavioural deviation checks.
Alert and Quarantine Configuration
Alert thresholds and quarantine policies are configured to match your risk tolerance. High-confidence detections are quarantined automatically. Lower-confidence flags are reviewed by your team or ours.
Simulation and Validation
Simulated spear phishing campaigns targeting your VIP users validate detection effectiveness. Results are used to refine models and identify staff who need additional awareness training.
Continuous Threat Intelligence Updates
Threat intelligence feeds are updated continuously with new spear phishing tactics, techniques, and procedures. Your protection evolves automatically as the threat landscape changes.
How we have stopped targeted attacks on UK organisations.
CFO Targeted with Personalised Wire Fraud
A London financial services firm had their CFO targeted with a highly personalised email referencing a real ongoing deal, requesting an urgent transfer to a new escrow account.
Contextual content analysis flagged the urgency pattern and unusual payment request. Email quarantined before delivery. CFO alerted. No financial loss. Attack infrastructure reported to authorities.
IT Administrator Credential Harvest Attempt
A Bristol technology company had their IT administrator targeted with a convincing email appearing to come from a cloud vendor requesting re-authentication of admin credentials.
Behavioural baseline modelling identified the deviation from normal vendor communication patterns. Email blocked. Admin credentials remained secure. Vendor notified of impersonation.
HR Director Targeted for Payroll Data
A Glasgow healthcare organisation had their HR director receive a series of researched emails referencing real employee names and requesting payroll file exports for an audit.
OSINT correlation identified that sender details matched a known threat actor profile. Email chain quarantined. HR director briefed. Payroll data remained protected.
