Under Attack?
Business Email Compromise (BEC) response
Business Email Compromise (BEC) is one of the most common and most financially damaging cyber threats facing organisations today. At Integrity360, we help businesses stay one step ahead with proactive and tailored incident response to stop email fraud in its tracks.
What is business email compromise?
Business Email Compromise (BEC) is a sophisticated cyber attack that targets employees through social engineering and phishing. Attackers often impersonate trusted figures—such as CEOs or suppliers—by compromising email accounts or spoofing domains to make fraudulent requests look legitimate.
These attacks are designed to trick victims into transferring funds or disclosing sensitive data, often bypassing traditional security measures. Common targets include finance teams, HR departments, and executives.
BEC can lead to serious financial losses, reputational harm, and regulatory challenges. The impact on both SMEs and large organisations can be severe.
Integrity360 delivers rapid business email compromise response
24/7 incident response from expert cyber teams

As soon as we’re engaged, our cyber incident response specialists act swiftly—mobilising remotely or onsite the same day where necessary to contain the threat and begin recovery.
Forensic investigation and root cause analysis
Our digital forensics experts work quickly to identify how the compromise occurred and what data, if any, has been accessed or exfiltrated. We examine email logs, user behaviour, and system artefacts to build a clear timeline of events. Where required, we support legal teams with comprehensive evidence handling and expert reporting.
Fast-track recovery and compliance guidance
Integrity360 works closely with your internal IT and security teams to restore affected systems, secure compromised accounts, and get your business back online with minimal disruption. We also advise on any regulatory obligations, helping you meet compliance requirements with confidence.
The Integrity360 process for responding to business email compromise
When a Business Email Compromise (BEC) incident strikes, a structured and expert-led response is essential. At Integrity360, we follow a clear, effective process to investigate, contain, and resolve the threat—while helping you recover quickly and reduce the risk of recurrence.
Step 1 – Triage and mobilisation
As soon as we’re engaged, Integrity360’s Incident Response team initiates same-day triage. We assign a dedicated response lead, initiate stakeholder communications, agree reporting lines and call schedules, and begin immediate information gathering. Our priority is to understand the scope of the compromise, stabilise the environment, and launch the initial response plan.
Step 2 – Investigation and analysis
Our Digital Forensics and Incident Response (DFIR) specialists conduct a detailed analysis of the breach. This includes identifying the attacker’s point of entry, methods used to impersonate individuals or access sensitive data, signs of persistence, fraud exposure, and potential regulatory implications. Our findings form the foundation of a tailored mitigation strategy.
Step 3 – Containment and mitigation
We act swiftly to contain the threat, removing any footholds the attacker has established. This includes revoking unauthorised access, isolating affected accounts or systems, and implementing technical controls to prevent further compromise. We also apply best practice security hardening measures across your Microsoft 365 or cloud environment to reduce future risk.
Step 4 – Remediation and recovery
Once the threat is fully contained, we move to remediation. This involves eradicating the root cause of the attack, restoring affected services, and supporting secure password resets and Mult Factor Authentication (MFA) enforcement. We work closely with your teams to restore trust in communications and re-establish a clean operational state.
Step 5 – Data loss assessment and compliance support
Using advanced tooling and expert-led investigation, we assess the extent of any data loss, identify compromised communications, and evaluate the risk to personal or regulated information. If required, we help you meet GDPR or other regulatory obligations, supporting any breach reporting requirements with clear documentation and expert advice.
Step 6 – Post-incident review and resilience improvement
After recovery, we conduct a comprehensive post-incident review. This includes lessons learned, risk assessments, and recommendations for improving your email security, user awareness, and response capabilities. We provide a detailed incident report and advise on longer-term protection strategies, including managed detection and response (MDR) and cyber awareness training.

Incident Response FAQs
What is the difference between business email compromise and phishing?
While both involve deception via email, phishing typically casts a wide net, sending mass emails with malicious links or attachments. Business Email Compromise (BEC), on the other hand, is highly targeted. Attackers often impersonate trusted individuals to trick employees into making payments or revealing sensitive information. BEC is usually more sophisticated and financially motivated.
How do cybercriminals gain access to business email accounts?
Attackers use several methods, including phishing emails, credential stuffing, or exploiting weak passwords and lack of multi-factor authentication (MFA). Once inside a mailbox, they may observe communications for weeks before launching a carefully timed attack, such as intercepting an invoice or issuing fraudulent payment instructions.
Who is most at risk of a business email compromise attack?
BEC attacks often target finance departments, executives, HR teams, and accounts payable staff, anyone who has authority over financial transactions or access to sensitive business information. SMEs and large enterprises alike are at risk, especially those with weak email security or limited employee awareness training.
How can I tell if our business has been targeted by a BEC attack?
Warning signs include:
-
Unexpected requests for urgent wire transfers or changes to payment details
-
Messages with slight spelling variations in email addresses or domains
-
Unusual communication patterns, such as requests outside business hours
-
Pressure to bypass standard payment or approval processes
If you notice any of these signs, contact Integrity360 immediately for investigation and response.
What should I do if we fall victim to a BEC scam?
-
Stop the transaction if it hasn’t been completed.

Notify your bank to initiate a recall of the funds.

Engage Integrity360’s Incident Response Team to contain and investigate the breach.
