Stop CEO fraud and supplier impersonation before it reaches your team.
Attackers impersonate your executives and suppliers with convincing precision. IP Four deploys AI-powered identity verification, domain lookalike detection, and authentication enforcement to block every variant of impersonation fraud across UK organisations.
Every layer of impersonation protection your organisation needs.
From executive identity verification to domain lookalike detection, we close every avenue attackers use to impersonate trusted identities.
Executive Identity Verification
Every inbound email claiming to originate from a senior leader is cross-referenced against verified identity profiles. Lookalike display names and spoofed addresses are flagged before delivery.
Supplier and Partner Impersonation Detection
Attackers frequently impersonate trusted suppliers to redirect payments or harvest credentials. Our system builds a verified profile of your supplier communications and flags deviations instantly.
Domain Lookalike Detection
Domains registered to look like yours or your partners are identified and blocked. Subtle character substitutions, hyphen insertions, and TLD swaps are all caught before the email lands.
DMARC, DKIM and SPF Enforcement
Authentication records are enforced at the gateway. Emails failing SPF, DKIM, or DMARC checks are quarantined or rejected based on your policy, eliminating direct domain spoofing entirely.
Real-Time Impersonation Alerts
When an impersonation attempt is detected, the targeted recipient and your IT team are alerted immediately. Full forensic detail is provided so the threat can be investigated and escalated.
Impersonation Threat Reporting
Monthly reports show which executives and suppliers are being targeted, attack frequency, and trends over time. Board-ready summaries demonstrate the value of protection and inform policy decisions.
From identity baseline to continuous protection.
Identity Baseline Assessment
We map all executives, key staff, and trusted suppliers whose identities could be impersonated. Verified sender profiles are built from your existing legitimate email traffic.
Authentication Record Audit
SPF, DKIM, and DMARC records are reviewed and corrected where needed. Enforcement policy is set to quarantine or reject based on your risk tolerance and operational requirements.
Impersonation Rules Deployment
Custom impersonation rules are deployed covering executive names, supplier domains, and lookalike patterns. Rules are tuned in audit mode before enforcement to eliminate false positives.
Ongoing Monitoring and Refinement
New executives and suppliers are added to protection profiles as your business changes. Monthly reporting tracks attack attempts and policy effectiveness across your organisation.
Staff Awareness Integration
Targeted awareness content is delivered to staff who have been impersonation targets. Simulated impersonation scenarios are included in phishing simulation programmes.
Incident Response Support
When a successful impersonation attempt is identified, we provide immediate incident response support including forensic analysis, retroactive mailbox remediation, and supplier notification.
How we have protected UK businesses from impersonation fraud.
Finance Team Targeted by CEO Fraud
A Manchester professional services firm had their finance team receive a series of emails appearing to come from the managing partner requesting urgent wire transfers to a new account.
Executive impersonation rules flagged the emails before delivery. Finance team alerted. Attack pattern blocked across all variants. No financial loss sustained.
