Why Monitoring and Consulting?

DomainGuard's founders spent decades on the offensive side of security. Hundreds of authorized cyberattacks against America's largest enterprises across financial services, healthcare, manufacturing, and government taught us where attackers look first, which controls fail under pressure, and how lookalike infrastructure and brand abuse get weaponized.

Today we run that same playbook in reverse. Continuous external monitoring catches what is in flight; consulting engagements harden what monitoring sees and validate what it should see next. The two compound, sharing one team and decades of context on how attackers actually move.

Common Questions

What People Ask Us First.

DomainGuard is a managed external cybersecurity monitoring service. We watch your approved and vendor domains, your brand presence across app stores, social, search ads, and the dark web, and your internet-facing infrastructure, all 24/7. When a lookalike, impersonation, or exposed asset shows up, our team drives the takedown directly with the registrar, platform, or host so your team is not stuck chasing it.

Our fastest takedowns are under 120 seconds from malicious-intent detection to takedown submission. Average takedowns are measured in hours, not days. The full timeline depends on the registrar's response and the venue (search engine, social platform, app store). DomainGuard runs the takedown workflow on your behalf so your team does not need to chase registrars, hosts, or platform abuse desks.

Continuous data harvesting and analysis algorithms filter the bulk of non-threats automatically. Every alert that reaches you is triaged and validated first, so DomainGuard sees more, flags less, and what we flag is actionable. False positives erode trust and waste your team's time, and we commit to that step before anything reaches you.

Yes. The API Integration tier pushes DomainGuard threat intelligence into SOAR, SIEM, and ticketing systems. It works alongside any of the three monitoring tiers and lets you ingest detections, takedown events, and asset changes into your existing alerting and response workflows. Common destinations include Splunk, Sentinel, Cortex XSOAR, ServiceNow, and Slack.

Mid-to-large enterprises with high-value brands, domains, or trademarks. Customers span financial services, fintech, healthcare, retail, SaaS, manufacturing, higher education, and pharmaceutical data. Sizes range from regional credit unions and community banks to global manufacturers and century-old financial institutions. If a brand or domain is worth impersonating, monitoring is worth running.
