What Is Dark Web Monitoring and Does My Business Need It?
A clear, direct answer to this question — written for UK business owners and IT decision-makers.
Direct Answer
Dark web monitoring continuously scans dark web forums, marketplaces, and data dumps for your business email addresses, credentials, and sensitive data. When stolen credentials appear for sale, you are alerted before attackers use them. Most businesses discover compromised credentials only after an account has been breached. AMVIA includes dark web monitoring as part of its managed cybersecurity service, with automated alerts for any matching credentials.

BEC is a type of fraud where attackers impersonate executives or suppliers to trick employees into transferring funds or sharing sensitive data. BEC attacks increased 33% in 2025. The average loss per BEC incident is $137,000. Even organisations with fewer than 1,000 employees face a 70% weekly probability of a BEC attempt.
The top threats are phishing (85% of breaches), ransomware (doubled year-on-year), business email compromise (increased 33% in 2025), and supply chain attacks (35.5% of all breaches now originate from third parties). AI-powered attacks are accelerating all of these threat categories.
43% of UK businesses experienced a cybersecurity breach or attack in the past 12 months, according to the DSIT Cyber Security Breaches Survey 2025. For medium-sized businesses, this figure rises to 67%. Phishing remains the most common attack type, affecting 85% of businesses that reported a breach.
MFA requires two or more verification methods to access an account. Microsoft reports that over 99.9% of compromised accounts did not have MFA enabled. Only 40% of UK businesses have two-factor authentication enabled (DSIT 2025). MFA can prevent more than 99.9% of account compromise attempts.
