What's at stake
Your domain is your identity. Protect it like one.
Domain impersonation doesn't just put your organization at risk — it puts everyone who trusts your brand at risk. Without protection, attackers can send email as you, register domains that look like you, and run campaigns in your name.
Your domain spoofed to attack your clients
Attackers send emails that appear to come from your domain — targeting your clients, partners, or vendors. Your brand takes the reputational hit for an attack you didn't send.
Lookalike domains registered against you
Cybercriminals register domains that closely resemble yours — aegisys-cloud.ca, aegisys-support.com — and use them to deceive people who trust your brand.
Unauthenticated email passes as legitimate
Without DMARC enforcement, anyone can forge your From: address. Email receivers have no way to distinguish your genuine emails from spoofed ones.
Brand used in mass phishing campaigns
Your organization's name and logo are used in large-scale phishing campaigns entirely outside your control — damaging trust with clients who have never even been targeted before.
Without DMARC enforcement, anyone can send email as you.
DMARC (Domain-based Message Authentication, Reporting & Conformance) is the email authentication standard that tells receiving mail servers what to do when someone sends email using your domain without authorization.
Without a DMARC policy at enforcement level, spoofed emails from your domain will pass directly into your clients' inboxes. Aegisys implements and manages DMARC enforcement end-to-end — including the critical alignment work that prevents breaking legitimate email flows.
Monitor
DMARC policy deployed in reporting-only mode. Aegisys maps all legitimate email sources — no mail is blocked yet.
Align
Legitimate senders (CRM, payroll, marketing) are configured with correct SPF/DKIM alignment so enforcement won't break them.
Quarantine
Policy tightened to quarantine unauthenticated email. Unauthorized senders go to spam rather than the inbox.
Reject
Full enforcement. Unauthenticated email purporting to be from your domain is rejected outright — before it reaches anyone.
What's included
Complete domain and brand protection. Fully managed.
Aegisys doesn't just deploy Barracuda Impersonation Protection — we manage the ongoing configuration, reporting, and response so your domain stays protected as your email ecosystem evolves.
DMARC implementation & enforcement
Aegisys implements and manages DMARC (Domain-based Message Authentication, Reporting & Conformance) end-to-end — from initial policy in monitor mode through full enforcement.
- SPF, DKIM, and DMARC configuration and alignment
- Phased enforcement: monitor → quarantine → reject
- Ongoing policy management and tuning
- DMARC aggregate and forensic report analysis
Real-time DMARC reporting & visibility
Full visibility into who is sending email using your domain — legitimate sources and unauthorized senders alike — so you can act before damage is done.
- Dashboards showing all email sources per domain
- Unauthorized sender identification and alerting
- Legitimate source inventory and alignment
- Historical trend analysis
Lookalike domain monitoring
Continuously monitors newly registered domains that closely resemble yours — catching copycat domains before attackers can weaponize them against your clients.
- Daily scan of new domain registrations
- Typosquatting and homoglyph detection
- Subdomain impersonation monitoring
- Automated alerts with registrant details
Brand protection & fraud detection
Monitors the broader internet for unauthorized use of your brand identity — websites, email campaigns, and impersonation attempts that exploit your name and reputation.
- Brand mention and misuse monitoring
- Phishing site takedown support
- Domain abuse reporting workflows
- Threat intelligence integration
Automated source authorization
As your email ecosystem is mapped, legitimate third-party senders (CRMs, marketing platforms, payroll systems) are authorized automatically — keeping DMARC enforcement clean.
- Automated authorized sender detection
- Third-party platform SPF/DKIM alignment
- No business disruption during enforcement
- Change tracking and approval workflows
Compliance & audit documentation
DMARC enforcement is increasingly required by cyber insurance policies and enterprise vendor assessments. Aegisys provides documentation of your domain authentication posture.
- DMARC policy status documentation
- Enforcement history for insurance audits
- Vendor security questionnaire support
- Meets cyber insurance authentication requirements
Doc says
“Your clients trust that email from your domain is really from you. Without DMARC enforcement, that trust can be exploited by anyone — and it's your reputation that pays the price, not theirs.”
Managed end-to-end
Aegisys handles the full DMARC lifecycle — implementation, tuning, reporting, and enforcement — so you don't have to become an email authentication expert.

Who it's built for
Any organization whose brand is worth protecting.
Law firms
Clients receiving fraudulent emails from a spoofed law firm domain can cause irreversible reputational and legal damage. DMARC enforcement eliminates this vector entirely.
Learn moreHealthcare organizations
Patient-facing email must be unambiguously authentic. Domain spoofing in healthcare can compromise patient safety and trigger PHIPA breach obligations.
Learn moreFinancial services
Wire fraud, invoice fraud, and payment redirect attacks frequently exploit spoofed financial institution domains. DMARC enforcement and lookalike monitoring are essential.
Government & municipal
Spoofed government domain email undermines public trust and creates real liability. Domain authentication is increasingly mandated for government email systems.
First Nations organizations
Community-facing communications need to be trustworthy. Brand protection ensures your domain isn't used to target your community members.
