Stop spoofing and phishing at the inbox
SPF, DKIM and DMARC enforcement plus phishing filtering - so your domain can't be spoofed and malicious mail doesn't land.

Email is still how most breaches start, not because email security technology got worse, but because attackers stopped trying to break in and started asking nicely, using domains that look almost right and messages that read exactly like your CFO. Since November 2025, Gmail has permanently rejected unauthenticated bulk mail, and Microsoft followed with full enforcement on Outlook.com the same year, which means a weak email security posture doesn't just risk a breach anymore. It risks your email not being delivered at all.
Vinca Cyber's email security practice covers both sides of that problem (stopping malicious mail from reaching your people, and making sure your own domain can't be spoofed to attack someone else's) bringing the same 360° Cyber Resilience approach we've applied for 22 years to the inbox, powered by our partnerships with HEC and PowerDMARC.
Email security covers two related but distinct jobs. The first is electronic mail security in the traditional sense - filtering spam, phishing, malware attachments and business email compromise attempts before they reach an inbox. The second, increasingly critical since major providers tightened enforcement, is domain authentication: SPF, DKIM and DMARC, the three protocols that let receiving mail servers verify a message actually came from your domain rather than someone impersonating it.
Email security in network security terms sits at the perimeter closest to your people - most other network controls assume a message already got through; email security is what decides whether it does.
Most providers treat email security as a set-and-forget spam filter. We cover content-level filtering and domain-level authentication together.
A full email health check across your mail flow, authentication records and existing filtering, powered by HEC.
Hosted, managed setup and guided enforcement rollout, from monitoring to full rejection, via PowerDMARC.
Advanced filtering to check phishing link content and attachments before they reach a user's inbox.
Continuous alerts if someone attempts to spoof your domain, plus regular email security tools review as your mail infrastructure changes.
Detection tuned to the impersonation and payment-diversion patterns that bypass traditional spam filters.
Your domain has no DMARC record, or one set to monitor-only rather than enforcement
Customers or partners have reported receiving suspicious mail that appears to be from your domain
Your team can't say with confidence whether SPF and DKIM are correctly aligned
A recent bulk-sending change means your authentication setup hasn't been reviewed against current Gmail and Microsoft requirements
