Accurate, automated inbound email security

Prevent advanced email attacks including BEC, QR code phishing, HTML smuggling, callback phishing, extortion, VIP impersonation, malware/ransomware, and more with adaptive inbound email threat detection.

We tested Sublime against live threats, and it consistently outperformed every other platform. That’s when we knew it was the right choice.

Stop attacks, save time

Sublime keeps inboxes safe while decreasing the effort for security teams.

Fewer false positives

By leveraging AI and machine learning within detections, Sublime catches more attacks while generating fewer FPs.

Automated triage

Security teams can automate email triage based on user reports, attack types and TTPs, department or user-level risk, and more.

Self-healing coverage

ADÉ, the Autonomous Detection Engineer, creates and updates coverage autonomously, so Sublime evolves with attacks.

Email security that handles threat evolution

Sublime’s adaptive approach to inbound email security combines behavioral analysis, AI agents, and machine learning to detect and stop the full spectrum of email attacks.

01

Autonomous triage and coverage

Our AI-powered Autonomous Security Analyst (ASA) fully automates triage and remediation of user-reported emails. Then our Autonomous Detection Engineer (ADÉ) takes ASA results and closes coverage gaps for novel attacks.

02

Layered detection methods

Sublime uses a combination of AI agents, machine learning, and behavioral analysis to shut down email attacks with industry-leading efficacy.

03

In-depth multi-signal enrichment

Sublime deeply inspects every part of a message and leverages behavioral context, natural language understanding (NLU), computer vision (CV), link analysis, QR code analysis, logo detection, Base64 decoding, recursive file explosion, entity recognition and more to detect sophisticated attacks.

04

Herd immunity with automatic quarantine

Sublime automatically quarantines new messages that match previous user reports by grouping similar content.

Frequently asked questions

What is inbound email security?
Inbound email security protects organizations from email-borne threats like phishing, malware, and business email compromise (BEC) before they reach user inboxes. It uses behavioral analysis, machine learning, and threat intelligence to analyze incoming messages and block or quarantine malicious emails while allowing legitimate communications through.
How does inbound email threat protection work?
Inbound email threat protection analyzes every incoming message using multiple detection layers including detection rules, machine learning models, and threat intelligence feeds. Messages are scanned for malicious content, suspicious links, attachments, and behavioral patterns. Threats are automatically blocked or quarantined based on risk scores and customizable policies.
What makes Sublime different from other inbound email security solutions?
Unlike one-size-fits-all solutions, Sublime provides full transparency. Our org-specific protections deliver a demonstrably higher catch rate, and for advanced teams, the platform is fully extensible.
Can inbound email security stop advanced attacks like QR code phishing?
Yes, modern inbound email security platforms like Sublime use specialized detection functions including QR code analysis, computer vision, and natural language understanding to identify advanced attack techniques. These multi-signal enrichments can detect QR code phishing, HTML smuggling, callback phishing, and other evolving threats traditional filters miss.
How do I reduce false positives in inbound email security?
Reduce false positives by using layered detection that combines layered logic with AI-powered signal analysis. For advanced teams, Sublime is fully extensible, allowing you to create organization-specific detections using MQL that are adapted to your unique context, dramatically reducing false positives compared to static, one-size-fits-all models.
