AegisAI Security

AegisAI is an API-based email security platform purpose-built for Microsoft 365 and Google Workspace. The platform utilizes autonomous AI agents to evaluate inbound mail across identity signals, sender behavior, and language intent. This multi-layered analysis enables the detection of highly sophisticated threats that often bypass traditional security gateways, specifically AI-powered spearphishing, compromised vendor accounts, and complex business email compromise (BEC). Rather than relying on static signatures, AegisAI analyzes user intent in every interaction. By understanding the unique communication patterns between specific senders and recipients, the platform identifies the subtle anomalies—such as shifts in urgency, tone, or phrasing—that signal a hijacked conversation or an impersonation attempt. Deployment is lightweight and non-disruptive, connecting directly via mail APIs without requiring MX record changes or altering mail flow. Beyond advanced social engineering, AegisAI provides comprehensive, native protection against phishing, malicious attachments, and zero-day malware. Its self-learning model also functions as an intelligent filter to neutralize persistent spam and promotional noise, ensuring a clean and secure inbox for both general users and high-target executives. This specialized filtering reduces the "alert fatigue" that often distracts SOC teams from high-priority security events. AegisAI leverages agentic investigation to secure every layer of the inbox, providing a robust defense against Account Takeover (ATO) attempts and Data Loss Prevention (DLP) risks. Unlike traditional tools that rely on basic reputation checks, AegisAI provides security teams with advanced AI forensics and actionable intelligence. Every detection—from a suspicious file to a subtle impersonation attempt—is supported by a clear evidence trail. This allows SOC teams to resolve the specific "blind spots" found in modern social engineering while maintaining total visibility into the evolving trust dynamics of their organization. By deploying a self-configuring control plane, AegisAI automates the remediation process, ensuring that once a threat is identified, it is neutralized across the entire enterprise instantly.
