Concentration risk: when half the internet depends on three companies
Modern infrastructure looks distributed—but often isn’t. Hidden dependencies across cloud providers, DNS, and routing create concentration risk that most organisations can’t see until systems fail together
The Internet Has a Map. Most Defenders Can't Read It.
The internet’s infrastructure is public—but fragmented. Without connecting DNS, BGP, WHOIS, and certificate data, defenders see isolated signals instead of the full attack surface
Why blocklists are always one step behind
Blocklists stop domains after they’ve already been used in an attack. By mapping the infrastructure behind malicious domains, registrars, hosting, DNS, and ASNs, security teams can uncover entire campaigns instead of chasing individual indicators
One Phishing Domain Is Never Just One
Blocking one phishing domain doesn’t stop the campaign. Phishing infrastructure is built in bulk, shared registrations, nameservers, hosting, and certificates. Detecting a single domain is just the entry point to a much larger network hiding behind it.
Your Vendors' Infrastructure Is Your Attack Surface Too
Your security perimeter doesn’t stop at your firewall. Every SaaS platform, payment processor, and third-party script extends your attack surface. When their infrastructure fails or is compromised, the impact flows directly to you, often without warning.
Attackers Change Their Domains. They Rarely Change Their Habits.
Security blocks domains. Attackers rotate them. But infrastructure patterns persist, and that’s where real detection begins.
