What is TSA SD02E Compliance?
TSA Security Directive Pipeline‑2021‑02E (SD02E) is a federally mandated cybersecurity directive issued by the U.S. Transportation Security Administration. It applies to owners and operators of critical transportation infrastructure and outlines enforceable performance-based requirements to protect against malicious cyber intrusions.
SD02E replaces earlier TSA guidance with mandatory technical controls, emphasizing secure remote access, identity and access management, and continuous monitoring for all systems supporting critical transportation infrastructure.
Organizations covered by the directive must submit a Cybersecurity Implementation Plan and demonstrate enforcement of the security controls outlined in Sections III.A through III.E of the directive.
How Does Xona Help with TSA SD02E Compliance?
The Xona Platform delivers secure, zero-trust access to operational technology (OT) and critical infrastructure systems without the risks associated with VPNs, jump servers, or shared credentials. With a hardened access gateway and built-in protocol isolation, Xona provides:
- Multi-factor authentication (MFA)
- Credential injection to eliminate shared account usage
- Browser-based, protocol-isolated access to OT systems (RDP, SSH, VNC)
- Identity-, role-, and time-based access control
- Full session logging and video recording
- Real-time monitoring and session termination
- Seamless integration with SIEM, AD/LDAP, and compliance systems
These capabilities align with TSA SD02E requirements across all critical sections including access control, audit logging, network segmentation, and threat detection.

Why TSA SD02E Compliance Matters?
Following high-profile attacks like the Colonial Pipeline breach, TSA SD02E raises the cybersecurity baseline for the U.S. energy transportation sector. Noncompliance exposes operators to regulatory action, reputational risk, and operational disruption.
Xona simplifies the technical enforcement of SD02E controls helping teams eliminate insecure access paths, maintain audit readiness, and protect the integrity of critical assets.
