About Adaptive Security

Adaptive Security sells a platform that consolidates security awareness training, phishing simulations, email security, AI governance and human risk monitoring. Adaptive Security says its products work together or stand alone.[2][3][14]

Adaptive Security says adversaries use AI and LLMs to rapidly generate sophisticated social engineering attacks that exploit organizational complexity at every level. For enterprises, Adaptive Security describes threats that include executive impersonation targeting finance and leadership teams, AI-generated spear phishing built from OSINT data, deepfake voice and video attacks, and inbound email threats that existing gateways miss. Adaptive Security describes attacks that arrive via email, SMS, voice, and video.[2][3][14]

Security Awareness Training consists of interactive training modules covering AI threats, phishing, voice cloning, and compliance, drawn from a library of over 1,000 resources. Triggered and one-time campaigns in Security Awareness Training run automatically, with completion tracked across the organization. Adaptive Security supports custom modules built from a customer's own policies using Adaptive's AI content creator. Adaptive Security says its healthcare training modules are designed to be completed in under 10 minutes. Adaptive Security integrates with Workday, ADP, and other common LMS platforms used in healthcare environments, and supports SCORM exports for organizations that need to push content into an existing learning management system.[2][3][5]

Phishing Simulations recreate the people, channels, and business situations employees trust. Adaptive Security simulates every major attack vector, including email phishing, SMS, voice calls, and deepfake video attacks. When someone fails a simulation, Adaptive Security delivers a short micro-lesson explaining exactly what to look for next time. Podium uses Adaptive Security's realistic voice and SMS phishing simulations alongside automated training campaigns, custom content, and integrations with Okta and Slack.[4][5][15][16]

Adaptive Security's Email Security re-analyzes every inbound message after native filtering to catch the attacks that reach the inbox anyway, then remediates them automatically. Threats are broken out by type: credential phishing, callback phishing, business email compromise, extortion, and malicious payloads. Adaptive Email Security detects and removes phishing attacks, including threats employees never report, and can investigate and remove detected threats across affected inboxes, including messages that have already been delivered. Adaptive Email Security examines who is making a request, how they communicate, and the business context behind the message to identify fraud that may contain no malicious link or attachment.[2][15][18]

The Phish Alert Button and AI-powered Phish Triage classify employee-reported emails and automatically take action. Adaptive Phish Triage automatically classifies and resolves high-confidence reports, allowing the security team to focus on messages that require attention. Adaptive Security can send verdicts and relevant context to supported downstream security workflows through integrations.[2]

Adaptive AI Governance builds a clear view of AI activity across a customer's organization. Adaptive Security says customers can see how employees use AI, prevent sensitive data exposure, and apply context-aware policies across browsers, desktop apps, and developer workflows. Adaptive Security defines shadow AI as the use of AI tools, accounts, or workflows that an organization has not approved or cannot properly see and govern. Adaptive Security distinguishes personal and company AI accounts used in browser-based workflows.[19][20]

For compliance training, Adaptive Security offers pre-built tracks for HIPAA, GDPR, PCI-DSS, CCPA, and more, with state and country-specific content in 40+ localized languages. Customers can upload a policy document or describe a requirement to generate training with AI. Adaptive Security exports audit-ready reports with completions and scores by framework, employee, and date.[3][21]

Adaptive Security says it is SOC 2 Type II certified, HIPAA compliant, and GDPR compliant. Adaptive Security connects to a customer's HRIS and identity provider so employee groups stay in sync automatically as people join, leave, or change roles. Adaptive Security describes Lake City Bank and Bay Federal among its customers, and says First Liberty achieved 98% security training completion, with staff finishing in about a day.[2][3][4][5][6][7][8][14][18][21][22]
