Stop Cyber AttacksBefore They Start
Award-winning, enterprise-grade domain monitoring that detects typosquatting, phishing, and impersonation-based attacks before they reach your customers and employees.
Why this matters now
Attack volume is rising and AI is making each one cheaper to launch. Reactive controls miss what arrives outside the inbox. Proactive monitoring closes that gap before customers see it.

What we do
Stop the impersonation. Stop the attack!
We watch the domains, sites, and certificates attackers use to impersonate your brand, then disrupt them before your customers ever see them.
Lookalike domains
The domains that pretend to be you
Attackers register near-identical versions of your domain. A swapped letter, a different TLD, a single Unicode character that looks the same to the eye. Most customers and employees won't spot the difference. The attacker then uses those domains to send invoices, run phishing sites, and steal credentials in your name.

Stop attacks before they start
Disrupt the attack while it's being built
Most security tools react after a payload lands. We focus on what happens earlier, when the attacker is registering domains, issuing certificates, and standing up infrastructure. Catch them there and the attack never reaches anyone.
See where we intercept attacksHow the system works
Four detection layers in. Clear verdicts out.
We pull live signals from domain registrations, search results, your own site visitors, and certificate transparency logs. Each event gets classified as Safe, Watch, or Threat, so your team only sees the ones that matter.

Disruption
When something goes live, we shut it down
Every minute an impersonating site stays up costs your customers. Once a threat is confirmed, our pipeline goes after it across every channel that can act, in parallel, with the evidence already prepared. Enterprise customers can pipe the same signals into their SOAR or SIEM through our API.
That's the platform. Experience it for yourself.
