Doppel Email Security is now generally available
The agentic email security solution that empowers you to fight back against social engineering attacks. Detection isn't enough. Disruption is the difference.
Cybersecurity solutions partner helping teams evaluate vendor suites, architect solutions, and deliver implementation with strong engineering support.
Mission Critical Systems Customers working with Mission Critical Systems on security vendor evaluation, solution architecture, implementation, and engineering support can use Doppel to address a different part of the attack chain: the domains, profiles, messages, voices, and impersonation campaigns designed to exploit trust.
When phishing, impersonation, and malicious domains cross boundaries between security operations, fraud, IT, communications, and the business, Mission Critical Systems and Doppel give customers a way to bring those threads together. Doppel's Threat Graph connects domains, profiles, ads, phone numbers, messaging activity, and other signals into campaign-level context so teams can see the attack story rather than a pile of unrelated indicators. That combination helps reduce fragmented alerts while giving teams more context for decisions that involve employees, executives, customers, or brand trust.
