Google Workspace powers more than 3 billion active users globally. From agile mid-market firms to global enterprise operations, Gmail and Google Workspace serve as the digital backbone for millions of teams.
Yet, despite this massive footprint, security leaders running Google Workspace environments face a frustrating dilemma: How do you defend your organization against sophisticated, AI-driven attacks without settling for AI black boxes or antiquated legacy gateways that conceal how AI decisions are being made and completely leave end-user education by the wayside?
Today, we are excited to bring KnowBe4 Defend to Google Workspace. This isn’t a bolt-on. It’s the same multi-engine behavioral AI threat detection, explainable verdict evidence, automated cross-mailbox remediation and point-of-risk teachable moments that Defend offers to Microsoft 365 customers, now natively for Gmail.
The Problem: Sophisticated AI Threats Target Google Workspace
Attacker tactics have undergone a seismic shift. Generative AI has enabled threat actors to operationalize personalized, payload-free business email compromise (BEC), executive impersonation, vendor supply-chain fraud and prompt injections at unprecedented scale.
According to our recent KnowBe4 Phishing Threat Trends Report:
- 85.8% of phishing attacks now leverage AI-generated content
- 84.4% of evasive phishing emails pass baseline DMARC, SPF and DKIM authentication checks
- Evasive BEC and social engineering bypass native mail filters at alarming rates because they contain no malicious links or traditional malware payloads for signature engines to catch
While Google Workspace provides foundational inbox filtering, organizations running Gmail have historically lacked access to an integrated security layer that combines advanced pre-execution threat detection, real-time employee coaching and rapid SOC remediation without introducing complex mailflow friction.
Enter KnowBe4 Defend for Google Workspace
Defend for Google Workspace is an API-integrated security and coaching engine natively built for Gmail. Powered by KnowBe4’s multi-engine AI models and informed by proprietary threat telemetry, Defend evaluates incoming message intent across linguistic, relational, header and attachment signals simultaneously.
Instead of acting as a silent point tool that leaves your employees completely out of the loop, Defend bridges technical detection and real behavior change, stopping advanced attacks while coaching your workforce at the exact point of risk:
- Color-coded visual labels encourage end users to stop and think before proceeding with a flagged email
- Real-time teachable moments explain precisely why emails have been flagged, giving end users actionable context to spot future threats
- Proven Risk Reduction: Current Defend customers experience 97% of users stopping from proceeding with a high-risk action when a teachable moment appears.
This extra layer of security allows you to lead with advanced AI while keeping your end users protected, educated, and vigilant.
What Customers Are Saying
"What I like most is AI and machine learning and real-time user feedback and coaching. Not only does it tell you if the email is phishing or spam, but it also tells why it is. Knowing the why will increase education and knowledge with spotting phishing and threats."
