Doppel Email Securityの一般提供を開始
ソーシャルエンジニアリング攻撃への反撃を可能にする、エージェント型メールセキュリティソリューション。検知だけでは不十分です。攻撃を阻止することが重要です。
KnowBe4 passively trains your people. Doppel tests them the way attackers actually do.
KnowBe4 is a security awareness training platform, offering a broad content library, email-focused phishing simulations, and click-rate-based risk scoring for organizations looking to reduce human risk.
Best for
Organizations seeking a traditional Security Awareness Training platform with a large content library, compliance coverage, and email phishing simulations. Particularly well-suited for teams that prioritize established content and email-based simulations.
Where they're a strong fit
KnowBe4 is a strong fit for organizations that need broad content coverage across compliance frameworks and engaging videos. Their foreign language support and large module library make them a fit for workforces prioritizing training breadth.
Side by side
Due diligence
These help security teams evaluate fit regardless of which solution they're considering.

Doppel runs live, dynamic simulations across voice calls, SMS, email, video-meeting impersonation, and QR with configurable chained flows and 95%+ deliverability, covering a wide range of channels attackers use today.
Doppel provides OSINT-backed recommendations for an expansive range of organizations, roles, and tech stacks based on intel gathered by reconnaissance agents, and dynamically translates campaigns into 100+ languages.

As a unified agentic social engineering defense platform, Doppel proactively recommends training and simulation campaigns based on actual attacker tactics, and ingests signals across the tech stack to model human risk — building resilience against modern threats.
“Our previous platform was effective five years ago, but the market has moved. We wanted training that reflects current attacks and rewards positive security behavior instead of feeling like punishment.”
Technology executive at a government organization
“We needed to move beyond an antiquated, email-centric approach. Doppel gives us the multimodal simulations and real-world attack workflows we were looking for.”
CISO at a global law firm
“Doppel fundamentally changed how we think about human risk. It's not just about running better simulations — it's about testing how attacks actually happen across channels. The Microsoft Teams simulation campaign showed us where our real exposure was, and gave us a way to measure and improve it. That's the difference between a program that looks good on paper and one that actually reduces risk.”
