Implement a comprehensive authentication system that verifies all users, devices, and interactions through a versatile, cloud-based platform designed for complete security. Axiad supports organizations in transitioning to a passwordless environment, mitigating the challenges and dangers associated with disjointed solutions, thereby enhancing their cybersecurity framework and empowering users effectively. By establishing robust security practices, breaking down silos, and adhering to compliance standards, enterprises can adopt advanced passwordless multi-factor authentication (MFA) solutions. In addition, organizations can fortify their defenses with government-grade phishing-resistant authentication methods. Move beyond traditional identity and access management (IAM) systems to establish secure user practices while ensuring compliance through passwordless and phishing-resistant MFA techniques. Furthermore, bolster machine identity verification and elevate overall security measures with an integrated, customizable public key infrastructure (PKI) solution that meets diverse organizational needs. This holistic approach not only simplifies security management but also provides a scalable foundation for future growth.

Strong digital security is possible with the world's most trusted on-prem identity and access management (IAM). Identity Enterprise is an integrated IAM platform which supports a wide range of consumer, worker, and citizen use cases. Identity Enterprise is ideal for high-assurance applications that require zero trust for thousands or millions users. It can be deployed on-premises as well as virtual appliances. Never trust, always verify. Your organization and user communities are protected both within and outside the perimeter. High assurance use case coverage includes credential-based access, smart cards issuance and best-in class MFA. This will protect your workforce, consumers, and citizens. User friction can be reduced with adaptive risk-based authentication and passwordless login. You can use digital certificates (PKI), which provide a higher level security, whether you have a physical smartcard or a virtual one.

Efficiently manage the entire lifecycle of certificates within your network, whether for on-premise or cloud-based Public Key Infrastructure (PKI) setups. Transition seamlessly from your current certificate authority through policy-driven automated processes for issuance, renewal, and revocation, effectively removing manual tasks and their associated mistakes. As enterprises increasingly depend on PKI to safeguard machines, devices, and user access via keys and digital certificates, HID IdenTrust, in collaboration with Keyfactor, provides a streamlined approach to PKI and large-scale automation of certificate lifecycle management. HID IdenTrust offers a managed PKI solution in the cloud that can issue public, private, and U.S. Government interoperable (FBCA) digital certificates, thereby enhancing the security of websites, network infrastructures, IoT devices, and workforce identities. Moreover, you can uncover all certificates throughout both network and cloud infrastructures with real-time inventories of public and private Certificate Authorities (CAs), along with distributed SSL/TLS discovery tools and direct linkages to key and certificate repositories, ensuring comprehensive visibility and management. This holistic approach not only improves security but also boosts operational efficiency across the organization.

Accops HyID represents an advanced identity and access management system designed to protect vital business applications and data from potential threats posed by both internal and external users by effectively managing user identities and scrutinizing access. It empowers organizations with robust control over their endpoints, facilitating contextual access, device entry restrictions, and a versatile policy framework. The integrated multi-factor authentication (MFA) works seamlessly with both contemporary and legacy applications, accommodating cloud-based and on-premises solutions. This authentication process is highly secure, utilizing one-time passwords (OTPs) sent via SMS, email, or applications, as well as biometric data and hardware identification through PKI. Additionally, the single sign-on (SSO) feature enhances security while simplifying user experience. Furthermore, businesses can keep track of the security status of their endpoints, including those of bring-your-own-device (BYOD) initiatives, allowing them to make informed decisions regarding access based on real-time risk evaluations. This comprehensive approach ensures that organizations remain agile yet secure in the face of evolving threats.

SeaCat is a comprehensive cyber-security and data privacy platform designed specifically for mobile and IoT applications, ensuring that users can build and operate their apps without encountering any cyber-security incidents.

SeaCat incorporates state-of-the-art security measures, including biometric authentication and hardware security modules, making it a modern choice for developers. The platform comprises three key components: the SeaCat SDK, which integrates into mobile or IoT applications; the SeaCat Gateway, which is installed in the demilitarized zone (DMZ) in front of backend servers; and the SeaCat PKI service, which facilitates enrollment, access, and identity management. By utilizing SeaCat, users can confidently protect their applications while focusing on delivering a smooth user experience.

A wide variety of outstanding enterprise security tools are available to organizations today. Some of these tools are hosted on-site, while others are offered as services, and there are also options that combine both approaches. The primary obstacle that companies encounter is not the scarcity of tools or solutions, but rather the difficulty in achieving seamless integration between these privileged access management systems and a unified platform for their oversight and auditing. GaraSign presents a solution that enables businesses to securely and effectively connect their security infrastructures without interfering with their current operations. By identifying and isolating the commonalities, GaraSign can streamline and centralize the oversight of critical areas within an enterprise, such as privileged access management (PAM), privileged identity management, secure software development, code signing, data protection, PKI & HSM solutions, DevSecOps, and beyond. Therefore, it is imperative for security leaders in enterprises to prioritize the management of data security, privileged access management (PAM), and privileged identity management among their responsibilities. Additionally, the ability to integrate these tools can significantly enhance overall operational efficiency and risk management.
