Why does email security need dedicated attention beyond a standard spam filter?

The vast majority of breaches start with a phishing email, and modern phishing attacks are specifically designed to slip past basic spam filters by mimicking legitimate senders and avoiding obvious red flags. Dedicated email security adds layers like advanced threat detection, link protection, and attachment sandboxing that basic filtering misses.

Does this integrate with Microsoft 365 or Google Workspace, or does it require a separate email platform?

It integrates with whatever platform you're already using, whether that's Microsoft 365, Google Workspace, or another provider. We layer additional protection on top of your existing platform rather than requiring you to migrate email systems.

Can email security solutions catch business email compromise attacks, not just malware?

Yes, and this matters since business email compromise, where an attacker impersonates an executive or vendor to trick someone into a wire transfer, doesn't always involve malicious attachments or links that traditional filtering catches. We layer in behavioral and authentication checks specifically aimed at this type of fraud.

Does improving email security reduce the risk from our social engineering testing findings?

Directly, yes. If our social engineering testing shows employees clicking phishing links, strengthening email security is one of the most effective technical controls to reduce that risk alongside the awareness training piece.

Email Threat Protection

Email Security Built Around How Attackers Actually Target People

Most organizations discover their email security gaps after a phishing attack succeeds or a wire transfer goes to the wrong account. Pluto Security builds email security programs before those moments happen. Our team understands both the technical controls and the attacker techniques used in modern email attacks, including the AI-generated spear phishing campaigns that have made legacy filters increasingly ineffective. We have deployed and hardened email security environments for healthcare organizations, financial services firms, law firms, and technology companies across the United States, and we bring that cross-industry experience to every engagement.

Layered Protection

Multiple controls address authentication, malicious content, impersonation, and suspicious behavior.

BEC Awareness

Security controls are designed with modern business email fraud scenarios in mind.

Configuration Expertise

SPF, DKIM, and DMARC policies are reviewed as part of the wider email security posture.

Threat-Focused Monitoring

Security activity is interpreted in the context of evolving email attack techniques.
