Best OT Secure Remote Access Software for Okta

SurePassID is a sophisticated multi-factor authentication solution that can be deployed in various environments to protect both information technology and operational technology sectors, encompassing essential infrastructure, older systems, on-site operations, air-gapped setups, hybrid clouds, and fully cloud-based systems. The platform accommodates numerous authentication strategies, including passwordless and phishing-resistant methods like FIDO2/WebAuthn (utilizing FIDO2 PINs, biometrics, or push notifications), alongside one-time passwords (OTP through OATH HOTP/TOTP), mobile push notifications, SMS, voice calls, and conventional techniques. SurePassID seamlessly integrates with popular operating systems, facilitating domain and local logins, RDP/SSH remote access, and even older or embedded Windows systems typically found in OT/ICS/SCADA settings, thus allowing for offline two-factor authentication when necessary. Additionally, it offers protection for VPNs, network devices, appliances, legacy applications, and web applications through SAML 2.0 or OIDC identity provider capabilities, as well as access protocols for network devices. This flexibility makes SurePassID an essential tool for organizations aiming to enhance their security posture in diverse operational landscapes.

Secomea Prime offers a robust solution for secure remote access and industrial IoT, specifically designed to cater to operational technology and industrial control systems. This platform empowers technicians, vendors, and maintenance crews to remotely access, configure, troubleshoot, and service machines like PLCs, HMIs, SCADA, DCS, and RTUs from any device, at any location, eliminating the need for VPNs, open ports, or incoming traffic. The system includes a versatile gateway known as SiteManager, which can be hardware or software-based, enabling connections to both legacy and contemporary OT equipment while supporting a wide array of protocols, such as Modbus, Ethernet/IP, serial/USB, and Layer-2 tunneling. Deployment is typically swift, often completed in less than a day per site, after which Secomea facilitates comprehensive remote-access management through GateManager and LinkManager. Administrators can implement detailed, role-specific access controls and ensure user authentication through secure methods like multi-factor authentication or single sign-on options such as Azure AD or Okta. Furthermore, every remote session is meticulously tracked, logged, and recorded to support audit, compliance, and troubleshooting efforts, providing an additional layer of security and accountability in the operational environment. This thorough oversight and ease of access significantly enhance operational efficiency and machine uptime.
