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

Darktrace / EMAIL

Darktrace / EMAIL secures email and collaboration by training exclusively on each organization’s own communication patterns, not shared threat intelligence. It builds a Unique Behavioral Profile for every user – spanning email, identity, DLP, and human risk – to catch novel phishing, business email compromise, and account takeover that signature-based tools miss by design. It’s recognized as a Leader in Gartner’s Magic Quadrant and in the 2025 Voice of the Customer for Email Security Platforms. Traditional secure email gateways and native protections rely on known threat intelligence, so they need a first victim before they can catch a new attack – and generative AI has only widened that gap. Darktrace / EMAIL takes a different approach: it uses Adaptive AI to build a Unique Behavioral Profile for every user, then detects deviations across inbound, outbound, and lateral mail and responds with precise, autonomous action. Key capabilities include: - Adaptive Email Security: Builds a Unique Behavioral Profile for every user across the full mail flow – inbound, outbound, and lateral protection, DMARC management, account takeover detection, data loss detection, and AI attack/GenAI visibility. Darktrace catches on average 17% of threats that leading SEGs miss on arrival. - Identity Detect & Respond: Adds autonomous response to account takeover – session termination and forced re-authentication – plus recovery and audit across email, SaaS, and cloud. - Email DLP & Collaboration Security: Suspicious emails are automatically quarantined, links are rewritten, and attachments are removed, extending detection with hold, redirect, and strip-sensitive-content response actions plus dedicated behavioral coverage across Microsoft Teams, Zoom, and Slack, all without interrupting legitimate business communication. - Adaptive Security Awareness Training: Personalizes training, phishing simulations, and just-in-time coaching to each employee’s actual behavior, with outcomes feeding back into the detection model to close the loop. For security teams, Darktrace / EMAIL reduces operational overhead by automating triage and response. Its Cyber AI Analyst provides contextual insights, while end-users benefit from clear, in-app narratives that explain why a message is suspicious – helping to reduce false phishing reports and improve awareness. Benefits for organizations include: - Coverage across email, collaboration, and SaaS platforms in one behavioral model. - Up to 90% less time spent triaging alerts, so security teams spend more time on higher-value work. - Native integration with Microsoft 365, Exchange, and Google Workspace that doesn’t disrupt mail flow. Darktrace / EMAIL is a Gartner Leader in both the Magic Quadrant and the 2025 Voice of the Customer for Email Security Platforms – recognition that tracks with what it actually catches: threats built for a specific business, not just known attack patterns.

Validity Engage

Validity Engage is an AI-native platform built for high-volume enterprise marketing teams that want every email to be better than the last. It covers the full email lifecycle: competitor intelligence, contact validation, design and testing, deliverability, and live email monitoring. Engage unifies capabilities formerly delivered across separate Validity products: (Formerly) Validity Litmus: Broken links, brand inconsistencies, and rendering issues that slip through review erode subscriber trust. Engage's email building, QA testing, spam filter testing, and accessibility checks—backed by LLM powered spelling and grammar review—catch issues before they reach a subscriber, giving teams control without slowing production. (Formerly) Validity Everest: Unnoticed deliverability issues quietly drain revenue. Engage's inbox placement and deliverability monitoring shows exactly where your emails land across every major provider, giving teams the visibility to catch problems and stay off blocklists. (Formerly) Validity BriteVerify: Invalid contact data drives up bounces and damages sender reputation. Engage's contact and email validation keeps the data behind every send accurate—automatically. It gives teams the confidence to send at scale without second-guessing the list. Engage also adds proprietary competitor intelligence, showing you what's working across the market before a campaign even sends. Sender Certification, an upgrade available with Engage, helps senders reach more inboxes—and stay there—as a trusted sender. Engage’s insights are powered by the Validity Intelligence Network, built on 25 years of exclusive partnerships, real-time visibility into inboxes worldwide, and signals from across the email ecosystem. The network spans more than 140 ISPs, tracks 35,000-plus brands, and processes 2.5 billion behavioral data points every day. Engage puts that intelligence to work through a team of agents that watch performance around the clock, recommend the next best action, and fine-tune campaigns without waiting to be asked.
