SecureW2 JoinNow

SecureW2 JoinNow is a cloud-native PKI and RADIUS passwordless authentication solution, securing human, machine, and AI agent identities with continuous trust. The JoinNow platform combines Dynamic Public Key Infrastructure (PKI) and Cloud RADIUS to facilitate real-time trust validation and continuous authentication for users accessing networks and applications. Before granting access, the platform reviews who is requesting access and whether the device meets security requirements. Once access is granted, the system continuously monitors device compliance to ensure that only trusted users and devices stay connected. The JoinNow platform caters to a diverse range of users, including K-12 and higher education institutions, mid-market businesses, and global enterprises. It also supports AI agent security by helping organizations apply certificate-based authentication and access policies to non-human identities. By providing scalable and resilient authentication solutions, SecureW2 addresses the unique security needs of various sectors without placing an additional burden on IT teams. The platform's ability to seamlessly integrate with existing identity providers, such as Entra ID (formerly Azure AD), Okta, and Google Workspace, allows organizations to implement adaptive, passwordless authentication without the need for complex upgrades or disruptions. By using certificate-based authentication, SecureW2 eliminates credential compromise risks entirely. Additionally, the platform addresses the high operational overhead that comes with managing legacy security systems by automating certificate issuance, revocation, and lifecycle management. This automation not only saves IT resources but also enhances visibility and control, providing real-time insights into authentication processes. Key features of the JoinNow platform include: - An agentless architecture that eliminates software bloat while ensuring secure and frictionless authentication. - An extensive policy engine that allows organizations to create customized policies that are automatically enforced both before and after authentication. - Continuous authentication that adapts in real time, validating access dynamically based on evolving security conditions. - Platform interoperability that ensures compatibility with any identity provider, mobile device management (MDM) system, and security stack. In summary, SecureW2 redefines authentication for modern businesses by ensuring that every access request is trust-validated. Its scalable, lightweight design enables rapid deployment and effortless scaling, allowing organizations to maintain robust security without the complexities and costs typically associated with traditional authentication solutions.

EZCA

EZCA is a managed Cloud PKI and Certificate Authority for hybrid and cloud workloads, built by ex-Microsoft PKI engineers and the first of its kind on the market. EZCA replaces complex on-premises AD CS deployments and per-user cloud PKI services with a managed cloud CA priced at a flat $200 per certificate authority per month, with no surprise charges as you scale. SOC 2 Type II, ISO 27001, and FIPS 140-2 Inside, out of the box. EZCA delivers deep native integrations with Microsoft Entra ID, Intune, Azure Key Vault, and Azure IoT Hub, so Microsoft-centric teams get certificates issued, rotated, and consumed by Azure workloads following Microsoft best practices, without the expired certs, outages, and manual NDES connectors that haunt legacy PKI. Built-in support for ACME, SCEP, OCSP, and smartcards covers every certificate workflow a modern enterprise runsm, including scenarios Microsoft Cloud PKI does not: SCEP for Intune, Jamf, and other MDM platforms, smartcard issuance, Azure IoT Hub authentication, and one-click Azure Key Vault certificate rotation. For platform and security teams, EZCA's integration with public PKI providers automates the certificate lifecycle end-to-end: critical now that Apple and Google have set a course toward 47-day TLS certificates. What used to require a handful of renewals a year will soon require dozens per certificate; EZCA's automation, monitoring, and alerting handle the volume so teams don't have to. Common deployments include: - Replacing AD CS without standing up a new CA hierarchy or NDES servers - Issuing device certificates at scale via Intune, Jamf, and other MDM platforms (Windows, macOS, iOS, and Android) - Securing Wi-Fi and VPN with certificate-based authentication via EZRADIUS - Authenticating IoT and healthcare devices with X.509 in Azure IoT Hub - Workload identity and encrypted communications for internal APIs, microservices, and containers - Auto-rotating TLS certificates stored in Azure Key Vault Unlike traditional PKI vendors that require complex CA hierarchies, hardware provisioning, and per-user pricing that punishes growth, EZCA is delivered as a fully managed service. HSM-backed roots, high availability, disaster recovery, and 24/7 support are included by default. There are no agents to install on servers and no on-prem connectors to maintain. EZCA is available in the Azure Marketplace, Microsoft Security Store, and Jamf Marketplace, and is trusted by enterprises in healthcare, finance, manufacturing, and critical infrastructure to secure identity, encrypt communications, and govern certificate lifecycles across hybrid, cloud, and IoT environments.

SSLBoard

SSLBoard delivers comprehensive TLS security audits and compliance-ready reports for any domain, on demand. Scan once, get a complete picture of your organization's TLS posture across every host, certificate, cipher suite, and protocol, all mapped against the compliance frameworks that matter to your business. SSLBoard goes beyond certificate discovery. It evaluates your entire TLS estate against 17 regulatory and industry frameworks including PCI-DSS v4.0.1, NIS2, ISO 27001, SOC 2, DORA, HIPAA, FedRAMP, NIST SP 800-52, and others. Each finding is scored, prioritized by compliance impact, and tied to specific regulatory requirements so security teams and auditors know exactly what to fix and why it matters. Every scan checks certificate health, protocol versions, cipher suite strength, forward secrecy, HSTS and web hardening, DNSSEC configuration, and post-quantum cryptography (PQC) readiness. SSLBoard detects weak or unsafe cipher suites, missing CAA records, deprecated protocols, and certificates approaching expiration, then tells you which compliance obligations each finding affects. Reports are structured for both human readers and machine consumption. Markdown summaries, CSV exports, and structured data formats make it easy to feed results into existing workflows, AI assistants, or compliance documentation pipelines. No account required, no integration overhead, no agents to install. Point SSLBoard at a domain and get actionable audit evidence in minutes. SSLBoard serves IT administrators, security teams, compliance officers, and auditors who need defensible TLS assessment data without the complexity and cost of annual enterprise contracts. Pay per report, scan any domain regardless of certificate authority or hosting provider, and get results that are ready for your next audit review.
