HSM IT ServicesEmail Security
Stop phishing, fraud and impersonation before they reach your inbox or your bank account. Our Email Security protects your organization from phishing, malware, business email compromise and domain spoofing. We combine advanced filtering, sender authentication with SPF, DKIM and DMARC, account protection and staff reporting tools, so fraudulent messages are blocked and suspicious ones are caught quickly.
Email remains the most common starting point for cyber attacks because it reaches people directly. Phishing messages try to steal passwords, attachments deliver malware, and business email compromise uses impersonation or a hijacked mailbox to redirect payments. These attacks increasingly use legitimate services and well-written text, so they slip past basic filters. Our Email Security adds protection at the application layer and at Layer 8, the people reading the messages.
We deploy advanced filtering that analyzes links when clicked, opens attachments in isolated environments and detects impersonation of executives, suppliers and familiar brands. Your domain is protected with SPF, DKIM and DMARC, configured carefully and moved to an enforcing policy so criminals cannot easily send email that appears to come from you. Mailbox rules, forwarding and unusual sign-ins are monitored, since attackers who gain access often hide their activity using these features.
Technology works best with an engaged team. Staff get a simple button to report suspicious messages, and reports are reviewed so real threats can be removed from every inbox. We help you set clear procedures for verifying banking changes and urgent payment requests, which is the most effective defence against invoice fraud. Optional email encryption and data loss prevention help protect personal and health information sent by email under PIPA and HIA.

How it works
Assess

Respond
We review reported messages, remove threats across mailboxes and adjust controls as tactics change.
Who it is for
Email Security suits every organization that uses email to communicate with clients, suppliers and staff, and it is especially important for businesses that send or receive invoices and payments, firms handling trust funds or confidential documents, and clinics exchanging health information. It complements Microsoft 365's built-in protection and pairs naturally with security awareness training.
Questions we hear
What are SPF, DKIM and DMARC?
They are email authentication standards. SPF lists the servers allowed to send mail for your domain, DKIM adds a digital signature to messages, and DMARC tells receiving servers what to do with mail that fails those checks. Together, properly enforced, they make it much harder for criminals to send email that impersonates your domain.
Isn't Microsoft 365 filtering enough?
Microsoft 365 includes useful protection, and with proper configuration it handles a large volume of threats. Many organizations add advanced filtering, impersonation detection and better reporting workflows, particularly if they are frequent targets of fraud. We assess your current protection and recommend whether to tune Microsoft's tools, add licences or use an additional service.
How can we stop invoice and payment fraud?
Technology helps, but the strongest control is a process. Require that any change to banking details or any urgent payment request is verified by phone using a number you already have on file, not one in the email. Combine that with impersonation filtering, mailbox monitoring and staff training, and most payment fraud attempts fail.
