The threats email security services are judged on

Three problems come up again and again: phishing in the inbox, your domain being spoofed and supplier payments redirected.

38%

Phishing that reaches the inbox

Phishing remains the most common attack on UK businesses by far. The UK Government’s Cyber Security Breaches Survey 2025/2026 found 38% of businesses experienced it, so every message kept out of the inbox counts.

Criminals sending email as you

Without an enforced DMARC policy, anyone can send email that appears to come from your domain, to your customers and suppliers. The UK Government’s survey found 12% of businesses experienced impersonation attacks.

Supplier invoices redirected to criminal accounts

UK Finance’s Annual Fraud Report 2026 recorded £28 million in business losses to invoice and mandate scams in 2025, often after an email was intercepted or an account compromised. Criminals frequently pose as suppliers or builders.

Filtering, domain authentication and payment checks work best together, and each one can be put right.

Advanced filtering against phishing, spoofing and business email compromise

Email security filters phishing, spoofing and malicious attachments before they reach an inbox, while authentication controls like DMARC stop your own domain being impersonated. Cybit deploys both together, because one without the other leaves a gap attackers know how to exploit. Businesses need this most urgently in finance and legal, where invoice fraud and business email compromise carry serious financial risk.

Why Choose Cybit

Most organisations run filtering and leave authentication half configured, which means an attacker who cannot reach the inbox can still send email as you. We deploy both together, because DMARC without filtering and filtering without DMARC each leave a gap attackers know how to use. This matters most in finance and legal, where invoice fraud and business email compromise carry direct financial loss rather than inconvenience. Ask us to check what your domain currently allows anyone to send.

Business Driver

The FBI’s Internet Crime Complaint Center recorded over $3 billion in reported business email compromise losses in 2025, across 24,768 complaints, within $20.9 billion of total reported cybercrime losses. Business email compromise relies on trust rather than malware, which is why filtering alone rarely stops it.

Frequently Asked Questions

For commodity spam, largely. For targeted phishing, impersonation and business email compromise, the default configuration is not built to catch it alone, which is why additional filtering and proper authentication are usually needed.

DMARC tells receiving mail servers what to do with email claiming to be from your domain that fails authentication. Without it enforced, anyone can send email that appears to come from your organisation. Most SMBs have it in monitoring mode and never move to enforcement.

An attack where someone impersonates a supplier, executive or colleague to redirect a payment or extract information. It relies on trust rather than malware, which is why filtering alone rarely stops it.

Filtering typically within days. DMARC enforcement is staged over a few weeks so legitimate mail flows are not disrupted.

UK Finance's Annual Fraud Report 2026 recorded £28 million in business losses to invoice and mandate scams in 2025, across 1,217 cases. Many start with an intercepted email or a compromised mailbox, which is why filtering, authentication and payment checks work best together.
