What is Email Security?

Email security is the layer of tools and rules that decides what mail actually reaches an inbox, filtering spam and known malware, checking whether a sender is who it claims to be, and flagging messages designed to trick someone into clicking, paying, or replying. Microsoft 365 and Google Workspace both include a baseline version of this built in. It catches a lot. It's also the layer most companies never think to question, because it's already running in the background.

The Gap

Defender and Google Workspace are built to stop bulk spam and known malware , not a convincing, individually written email with no bad link at all.

That's the gap Wizer Email Security closes, and the one this check measures.

Suspicious email

Gmail's Filter vs. Wizer Email Security

  • What Gmail Can't Catch

    • Attackers use Google against itself. In April 2025, phishing sent from a spoofed no-reply@google.com carried a valid DKIM signature and passed every check Gmail runs — because the attacker abused Google's own OAuth alerting system to generate it. The fake login page lived on sites.google.com.
    • BEC often carries no payload. Impersonation and payment-redirect emails frequently have no link or attachment to scan. They succeed on context, timing, and tone.
    • AI makes every lure one of a kind. Microsoft's 2025 Digital Defense Report found AI-generated phishing gets a 54% click-through rate vs. 12% for standard phishing — a 4.5x jump.
    • A filter decision isn't a trained employee. Gmail flagging or quarantining a message doesn't turn the attack into practice for the person it targeted.

  • What Wizer Adds

    • Built for Google Workspace. Connects directly through the Workspace API with admin-granted access, no MX changes.
    • Phishing and BEC detection. An AI second-opinion layer reviews every inbound message behind Gmail's filter.
    • Warnings people actually see. Clear banners on suspicious mail, plus a quarantine admins and users can review and release.
    • Faster response for IT. One-click reporting, a full admin audit log, and an AI agent that helps investigate incidents and write detection rules.
    • Real attacks become org-wide training. When one employee reports a real attack, Wizer rebuilds it as a simulation for everyone else. So the same trick doesn't land twice, plus a short training video on what happened and how to spot it next time.

FAQ

It stops known malware and bulk spam well. It's not built to catch a convincing, individually written email with no bad link in it, or a message that passes Gmail's own authentication checks because it's genuinely sent through a legitimate Google service an attacker abused.

Google Workspace's native filter is tuned for volume: known threats, flagged domains, bulk spam. Business email compromise, vendor impersonation, and look-alike domains that pass SPF and DKIM cleanly need a layer that looks at context and behavior, not just sender reputation.

No. It connects through the Workspace API alongside Gmail's existing filter, with no MX changes, it adds a layer, it doesn't take over mail delivery or routing.

Yes. In April 2025, phishing sent from a spoofed no-reply@google.com carried a valid DKIM signature and passed every check Gmail runs, because the attacker abused Google's own OAuth alerting system to generate it (BleepingComputer).

Wizer's Agentic MDR triages and investigates it, tells the employee whether their report was a real threat, and can turn a confirmed attack into a phishing simulation for the rest of the organization, so the same trick doesn't work twice on someone else.

It blocks phishing attacks before they reach an inbox, then turns the blocked attack into a short, AI-generated training video covering what happened, why it was dangerous, and how to spot it next time.

It assigns each employee a dynamic risk score based on the real phishing attacks they actually receive, recalculated after every attack, and targets simulations and training at the highest-risk people and departments rather than running one generic program for everyone.
