SMART CLOUD EMAIL SECURITY

Get complete protection within minutes

MailInspector Cloud adds a supplemental multi-layered security to your cloud email services, such as Microsoft 365, Google Workspace and Zimbra. Its unique approach allows for an easy setup with API integration, completed in minutes, or a combination of Secure Email Gateway + API, getting the best of both.

Full protection

We add our exclusive filtering and security layers, reinforcing the provider's native protection. We check all emails, including internal and outbound, and neutralize threats even after delivery.

For every need

Each customer has different security needs. So we offer the option of integration with or without MX changes, also enabling the protection of hybrid environments (e.g. Google + Zimbra).

And even more benefits

Our integration includes mailbox add-ons; AI designed to prevent phishing and targeted attacks; integration with other security tools, including our awareness program; and post-delivery protection.

Advanced Features

Add AI-powered features to your provider's native security

Blocks phishing, BEC (Business Email Compromise), impostor email, targeted attacks, spear phishing, and fake invoices and payment requests. Internal emails are also filtered to prevent impersonation and insider threats.

Protects against targeted and persistent threats, including ransomware, zero-day malware, and social engineering based attacks. Our Advanced Threat Protection is powered by Smart Defender, our threat intelligence that analyzes more than 1 billion IOCs (Indicators of Compromise) daily.

With a Sandbox, files, documents and URLs are executed first in a controlled and secure environment. HSC’s sandbox leverages AI, machine learning and other techniques to analyze the item’s content and make sure it’s clean.

CDR removes malicious content from infected files, documents and HTML, protecting against zero-day malware. All actions are performed in a secure, isolated environment.

Real-time file, URL and IP scanning, based on heuristics, behavioral analysis and reputation filtering. Because it’s real-time, it protects users even after the email is delivered. It’s a powerful time-of-click protection.

Protect, Act & Integrate: with three main Post-Delivery features, MailInspector keeps your users safe even after the message is delivered.

  • Post Delivery Protection

    Our threat protection features (ATP, URL filtering and Sandbox) work in real-time, protecting the user even after the message has reached the mailbox.

  • Post Delivery Action

    Our mSOAR (Mail Security Orchestration and Response) automatically analyzes, removes and/or remediates malicious messages if a threat is identified after the email was delivered.

  • Threat Intelligence Integration

    MailInspector exchanges threat intelligence with other security platforms, such as SIEM, XDR, NDR, EDR, and others. With API integrations, it sends and receives information about IOCs, becoming a full email XDR.

MailInspector is the best choice for email security

Beyond advanced threat protection features, MailInspector Cloud offers even more benefits to supplement your email provider’s native security.
