This technology neutralizes common PLC vulnerabilities such as default passwords, password sharing, and credential theft, providing a highly secure and streamlined authentication process. > > Verdict: Rated \*\*\*\* by 0 users. Top-rated for **Overall Quality**. ----- ## Overview ### Key benefits of swIDch PLC-OTAC 1\. Enhanced Security PLC OTAC strengthens security by using dynamic one-time codes instead of static passwords. This approach significantly reduces the risk of credential theft and unauthorized access. Dynamic codes, valid for a single session only, are resistant to phishing, brute-force attacks, and other methods that exploit static passwords. 2. Passwordless Authentication PLC OTAC simplifies access with passwordless authentication, eliminating the need for static passwords. This reduces the risk of password-related breaches and lessens the burden on users who no longer need to manage complex passwords. By ensuring that only authorized users can access critical systems, PLC OTAC enhances security and operational efficiency. 3. Flexible Deployment Options PLC OTAC supports various deployment modes to meet different operational needs: - Standalone Mode: Installed directly on the PLC, this mode operates independently of network connectivity, ideal for environments with limited or unreliable network access. - Server Mode: Deployed centrally on a server within the OT network, this mode is suited for large-scale deployments. It allows multiple PLCs to redirect authentication requests to the OTAC server, which manages security centrally. - Hybrid Mode: Combining local and central server deployment, this mode provides local authentication on the PLC while also leveraging a central server for additional security and failover resilience. It ensures robust protection and continuous operations even during network outages. 4. Efficient Resource Usage PLC OTAC is designed to be resource-efficient, ensuring minimal impact on PLC performance and overall system operations. Its lightweight architecture is suitable for environments with limited processing power, allowing effective security without compromising system efficiency. 5. Seamless Integration PLC OTAC integrates smoothly into existing OT environments with minimal disruption. Whether used on individual PLCs or across multiple devices, it provides a straightforward implementation, enhancing security without requiring significant changes to current systems. 6. Operational Continuity The hybrid deployment mode of PLC OTAC ensures authentication remains functional during network outages or server failures. This resilience minimizes downtime and maintains operational integrity, allowing critical processes to continue without interruption. 7. Scalability PLC OTAC is adaptable to the scale of your organization. Whether you need to secure a single PLC or an extensive network of devices, PLC OTAC offers a flexible and scalable solution that meets diverse security requirements. 8. Improved User Experience The passwordless authentication provided by PLC OTAC simplifies the login process for users, eliminating the need for password management. 9. Compliance and Risk Management Implementing PLC OTAC supports compliance with industry standards and regulatory requirements related to cybersecurity. By adopting advanced authentication methods and minimizing reliance on static passwords, PLC OTAC helps meet regulatory expectations and manage security risks effectively. 10. Cost-Effective Security PLC OTAC offers a cost-effective solution for enhancing PLC security. Its efficient resource usage and integration reduce the need for additional hardware or extensive operational changes, providing security at a practical cost. In summary, PLC OTAC by swIDch provides numerous benefits, including enhanced security through dynamic codes, passwordless authentication, flexible deployment options, and efficient resource usage. Its integration, operational continuity, scalability, improved user experience, and support for compliance make it a valuable solution for safeguarding critical industrial control systems. ## About the vendor - **Company**: swIDch ## Commercial Context - **Target Audience**: 51–200, 201–500, 501–1,000, 1,001–5,000, 5,001–10,000, 10,000+ - **Deployment & Platforms**: Cloud, SaaS, Web-based, Windows (On-Premise), Linux (On-Premise), Android (Mobile), iPhone (Mobile), iPad (Mobile) - **Supported Languages**: English - **Available Countries**: Afghanistan, Albania, Algeria, American Samoa, Andorra, Angola, Anguilla, Antigua & Barbuda, Argentina, Armenia, Aruba, Australia, Austria, Azerbaijan, Bahamas, Bahrain, Bangladesh, Barbados, Belarus, Belgium and 208 more ## Features - Access Management - Authentication - Multi-Factor Authentication - Multiple Authentication Methods - Password Management - Secure Login ## Support Options - Email/Help Desk - Phone Support ## Category - [Authentication Software](https://www.getapp.sg/directory/1169/authentication/software) ## Related Categories - [Authentication Software](https://www.getapp.sg/directory/1169/authentication/software) - [Customer Identity and Access Management (CIAM) Software](https://www.getapp.sg/directory/3783/customer-identity-and-access-management-ciam/software) - [Privileged Access Management Software](https://www.getapp.sg/directory/1181/privileged-access-management/software) - [Identity Management Software](https://www.getapp.sg/directory/675/identity-access-management/software) - [Multi-Factor Authentication Software (MFA)](https://www.getapp.sg/directory/3814/multi-factor-authentication/software) ## Alternatives 1.
