# Best Intelligent Email Protection Software

  *By [Lauren Worth](https://research.g2.com/insights/author/lauren-worth)*

   Intelligent email protection, sometimes called human-layer security, is a class of software solutions designed to prevent a company’s employees from sophisticated email-focused cyberattacks. These tools use machine learning to analyze historical records of email content, user behavior, and email-based threats, identifying risks and developing a baseline for user behavior. Intelligent email protection products filter incoming emails to detect and block potential phishing attacks, attachments containing malware, and links to potentially dangerous websites. They also filter outbound emails to detect accidental data leakage, data exfiltration, and the misuse of privileged data.

Companies use these solutions because all employees are susceptible to traditional phishing attacks, targeted spear-phishing attacks, malware, and other email-based threats. Employees can also pose a risk if they unknowingly share sensitive information in noncompliant ways. Additionally, every business is at risk for insider threats, and these products will detect abnormal activity involving sensitive data.

Some intelligent email protection tools fall into the same category as [secure email gateway](https://www.g2.com/categories/secure-email-gateway) and [cloud email security](https://www.g2.com/categories/cloud-email-security), which are also used to prevent phishing attacks and malicious emails from reaching employees. Those solutions, though, do not provide the scope of intelligent automation capabilities needed to identify anomalies and detect risky behaviors. Some overlap also exists with [email anti-spam](https://www.g2.com/categories/email-anti-spam) solutions, which have an even smaller scope of capabilities limited to blocking spam and phishing attacks.

To qualify for inclusion in the Intelligent Email Protection category, a product must:

- Filter incoming and outgoing emails
- Utilize machine learning to develop employee baseline behaviors
- Detect and block unauthorized outbound emails and incoming emails containing advanced persistent threats

### Sublime Email Security Platform

Sublime’s agentic platform stops more email attacks with less work. Our AI agents work like a digital SOC team in your environment, triaging and blocking advanced threats while adapting protections at adversary speed. It provides full transparency and automation by default, with control on demand for advanced teams, eliminating vendor bottlenecks or one-size-fits-all limits. Core Outcomes (The What): - Stop More Attacks with Fewer False Positives - block sophisticated threats (BEC, novel phishing, QR-based phishing) and reduce the false positives that waste time and disrupt workflows. Our tailored protections deliver a demonstrably higher catch rate, validated by the world's most demanding security teams. - Automate the Abuse Mailbox - Our Autonomous Security Analyst (ASA) automates triage, investigation, and remediation of user-reported email, cutting MTTR from hours to seconds and freeing your SOC team to focus on the threats that matter most. - Adapt Defenses Automatically. - When a missed attack is identified, we can create new coverage in hours. Our Autonomous Detection Engineer (ADÉ) generates, backtests, and deploys org-specific coverage, eliminating vendor ticket limbo. Differentiators (The How): - A Team of Agents using AI, Not Just a Black Box - Sublime deploys a team of specialized agents - like an analyst and a detection engineer - that use AI to protect, triage, and adapt your defenses. Unlike an opaque, monolithic AI, our agentic approach provides full transparency into every action, with visible decision history, message lineage, and backtests. - Org-Specific Protection, Not One-Size-Fits-All - Our Distributed Detection Model (DDM) is the foundation of our platform. It runs per-environment coverage that adapts to the unique attacks you face, allowing us to safely deploy protections that would be noisy in global models - something centralized systems simply can’t support. This means higher day-one efficacy and fewer false positives. - Autonomous by Default, Control on Demand - By stopping more attacks and reducing false positives, Sublime delivers a superior autonomous experience that requires less work. For advanced teams, the platform is fully extensible, allowing you to author your own detections and hunt for threats with a level of precision that one-size-fits-all solutions can't. Innovative organizations including Spotify, Snowflake, Brex, Elastic, Compass, Anduril, SentinelOne, and others rely on Sublime to secure the business and keep teams focused on strategic defense. 🔗 Learn how Sublime helps security teams stop more attacks with less work at sublime.security

  SlashNext Integrated Cloud Email Security Slashnext Integrated Cloud Email Security enables organizations to stop 65% more targeted spear phishing, social engineering, business email compromise (BEC), and other malicious digital user attacks launched from legitimate, trusted sites. With power and 99.99% accuracy, SlashNext continuously detects and remediates threats missed by Microsoft Defender, ATPs, and relationship graph technologies. Powerful, Simple, Secure, Fast ROI Now organizations can leverage SlashNext’s award-winning AI threat detection to securely detect and remove targeted spear-phishing and other human threats that easily evade email security defenses. As targeted, well-crafted spear-phishing continues to rise dramatically in an environment where cyber criminals use automation and AI to increase the likelihood of compromising a target. The once-reliable relationship graphs, URL rewriting, and sandbox technologies of Secure Email Gateways (SEGs) cannot safeguard against rapidly evolving phishing tactics. Spear-phishing delivered through legitimate cloud services can bypass these cybersecurity solutions. Since these attacks focus on a person, the success rates are higher, providing the attacker with a lower-cost entry point into an organization.
