From Premium · Invoice fraud
An email from a supplier, new bank details, an urgent payment – that is how invoice fraud begins. Mailsecurity24 protects your company with three features that work together: brand protection, suspicious email checks and the partner radar. Entry-level protection is included from the Premium plan, full protection from Business.
Invoice fraud needs no malware. Criminals send a convincing email – and wait for someone to pay.
Good to know: The sender address often looks genuine – because it is either forged or comes from a domain that can easily be mistaken for the real one. That is exactly where Mailsecurity24 comes in.
Every day we check around 150 lookalike variants of your domain and alert you as soon as one is newly registered – with a safe preview.
Your team forwards an uncertain email to your report address. Shortly afterwards the result arrives: genuine or suspicious, with reasons.
See how well your suppliers, bank and tax advisor are protected against spoofing – and hear about changes and new lookalikes.
Fraudsters register domains that are easily confused with yours and send fake invoices in your name. Mailsecurity24 spots such lookalikes before your customers fall for them.
Good to know: Included from the Premium plan for one domain of your choice, from Business for all domains – including certificate monitoring.
An invoice with new bank details, an urgent request from management: your staff forward questionable emails to a dedicated report address – and get a clear result in about two minutes.
Good to know: Included from the Premium plan. The reported message is only checked and never stored.
In invoice fraud, criminals rarely forge your domain – they forge your supplier’s, your bank’s or your tax advisor’s. The partner radar shows how well your business partners are protected against email spoofing – and alerts you when something changes there.
Good to know: Included from the Premium plan with up to 5 partners, in the Business plan with up to 25 and in the Agency plan with up to 50 per organisation.
We see these patterns again and again – and these are exactly what Mailsecurity24 makes visible.
Good to know: Even a genuine mailbox can be hacked. Whenever bank details change, always call back your known contact – on the number you already have.
Enter the domain of your supplier, your bank or your own. The free domain check shows in seconds whether emails in that name are easy to forge.
Free check · no sign-up
Check in seconds whether your domain is protected against email spoofing – or whether an email really comes from the stated sender.
Send any email to a one-time address – we show in seconds whether SPF, DKIM and DMARC passed. With a report and stamp.
Send any email from the address you want to check to:
For companies that receive or send invoices by email – from small trades businesses to mid-sized firms. Protection matters most when several people approve payments.
Entry-level protection is included from Premium: report address, brand protection for one domain and the partner radar for up to 5 partners. From Business you protect all domains – including certificate monitoring – and monitor up to 25 partners, on Agency up to 50 per organisation.
No. Your team simply forwards suspicious emails to your personal report address – from Outlook, Gmail, Apple Mail or Thunderbird. The result comes back by email. Brand protection and the partner radar run automatically in the background.
You receive an alert immediately by email and in the portal. The safe preview shows what is behind the domain without you opening the site yourself. If it is yours, mark it as “Belongs to us” with one click.
No – but it makes forgeries visible before money changes hands. Whenever bank details change, we also recommend calling back your known contact.
