Email Security Must Protect People and Your Domain

Attackers use email to steal credentials, redirect payments, deliver malware and impersonate trusted businesses. ITFR combines message protection, domain authentication, monitoring and response so email risk is managed beyond a basic spam filter.

✓Inbound email protection
Filter phishing, malicious attachments, unsafe links, spam and suspicious messages.

✓Business email compromise defence
Reduce executive, supplier, payment and display-name impersonation attacks.

✓SPF, DKIM and DMARC
Authorise legitimate senders and reduce unauthorised use of your business domains.

✓DMARC monitoring
Review authentication results, sending sources and enforcement readiness.

✓User reporting and response
Give users a clear way to report suspicious messages and coordinate investigation.

✓Security awareness alignment
Use attack patterns and reported messages to guide practical user education.

The result: fewer dangerous messages reaching users and stronger protection against misuse of your business identity.

COMMON QUESTIONS

Your email security and DMARC questions, answered

Can you help protect our domain from spoofing?

ITFR can map authorised senders, review email authentication and coordinate a staged DMARC implementation with monitoring and an agreed enforcement approach.

Will DMARC stop every phishing message?

No. Domain authentication addresses particular impersonation risks. Email filtering, account protection, reporting and user awareness remain important parts of the wider approach.

Can you review a suspected business email compromise?

ITFR can scope technical review of suspicious accounts, rules, messages and related identity activity. An active incident should be raised promptly through the incident response pathway.

What information is useful before a review?

Start with the domains, email platform, sending services and current concerns. Access, supported controls and implementation responsibilities are then agreed with your team.
