This 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. Each access request initiates an identity-based risk assessment, which determines the issuance of certificates and the corresponding access privileges. Once access is granted, the system continuously validates the compliance of devices, ensuring that only verified entities maintain their authorization. The JoinNow Platform caters to a diverse range of users, including K-12 and higher education institutions, mid-market businesses, and global enterprises. 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. SecureW2 effectively tackles several prevalent security challenges. Credential compromise remains a significant concern, as traditional passwords and multi-factor authentication (MFA) can be vulnerable. By utilizing certificate-based authentication, SecureW2 eliminates these risks entirely. Additionally, the platform addresses high operational overhead associated 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 SecureW2 include its agentless architecture, which eliminates software bloat while ensuring secure and frictionless authentication. The extensive policy engine allows organizations to create customized policies that are automatically enforced both before and after authentication. Continuous authentication adapts in real time, validating access dynamically based on evolving security conditions. Furthermore, the platform’s interoperability ensures compatibility with any identity provider, mobile device management (MDM) system, and security stack, making it a versatile choice for organizations looking to enhance their security posture. 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.

It automates the full SSL/TLS certificate lifecycle, from discovery through issuance, renewal, deployment, and monitoring, across mixed environments of Windows, Linux, and vendor appliances. WHY CERTIFICATE AUTOMATION MATTERS NOW Certificate lifetimes are shrinking by industry mandate. The maximum lifetime dropped to 200 days in March 2026. It falls to 100 days in March 2027 and 47 days by March 2029. Renewal work that used to happen once a year will soon happen every month. Spreadsheets, calendar reminders, and per-server scripts cannot keep up with that pace. CertKit makes renewal automatic, so shrinking lifetimes become a non-event. HOW CERTKIT WORKS CertKit separates certificate issuance from certificate deployment. A centralized ACME client handles validation and renewal in the cloud. The CertKit Agent then deploys certificates wherever they are needed. You don't install and maintain an ACME client on every server. You don't open ports. You don't hand out DNS credentials. Discovery: CertKit crawls Certificate Transparency logs to build a complete inventory of every certificate issued for your domains, including the ones nobody remembers deploying. Most teams find certificates they didn't know they had. Issuance and renewal: Centralized ACME issuance with support for wildcard and multi-SAN certificates. Domain validation uses a one-time CNAME delegation, so you never store DNS provider API credentials in a third-party tool. Set it up once and renewals run on their own. Deployment: The CertKit Agent runs on your servers and polls for updated certificates, then installs them automatically on Nginx, Apache, IIS, HAProxy, F5, Palo Alto, Citrix, Cisco, and other targets. Appliances and legacy systems that can't run ACME get the same automation as everything else. Monitoring: Real-time SSL monitoring with full TLS handshake validation, expiration alerts, and Certificate Transparency log monitoring that flags unexpected issuance for your domains. WHAT MAKES CERTKIT DIFFERENT No DNS API credentials required. Delegated validation through a one-time CNAME means a limited blast radius, not live credentials to your DNS provider sitting in someone else's database. Automation where ACME can't reach. Because issuance is separate from deployment, CertKit automates certificates on load balancers, firewalls, and appliances that per-server tools like Certbot can't touch. Vendor agnostic. Works with Let's Encrypt, private certificate authorities, and any ACME-compatible CA. No CA lock-in. Your keys can stay on your infrastructure. The optional CertKit Keystore keeps private keys on hardware you control. Auditable by design. The CertKit Agent and Keystore are source-available, so your security team can review exactly what runs in your environment. Built for MSPs. Manage certificates across many client environments from one account, with white-label support. Full automation without enterprise cost or complexity. Enterprise CLM platforms are priced and built for Fortune 500 PKI teams. CertKit delivers the automation without the six-figure contract or the six-month rollout. Plans and pricing are published, and every plan includes direct access to the engineering team. GET STARTED Every plan starts with a 90-day free trial, no credit card required. Connect your domains, and CertKit will show you every certificate you have before you configure a single renewal. #### Who Is the Company Behind CertKit Certificate Lifecycle Management? - **Seller:** [TrackJS](https://www.g2.com/sellers/trackjs) - **Year Founded:** 2013 - **HQ Location:** Stillwater, MN - **Twitter:** @trackjs 1,816 Twitter followers - **LinkedIn® Page:** [www.linkedin.com](https://www.g2.com/external_clickthroughs/record?secure%5Bsource_type%5D=product_profile&secure%5Btoken%5D=8f45fc255496d229be106ce62911a88b59deb5043f206d85c78d298bfacef03b&secure%5Burl%5D=https%3A%2F%2Fwww.linkedin.com%2Fcompany%2Ftrackjs%2F&secure%5Burl_type%5D=linkedin_company_website) 3 employees on LinkedIn® ### [Jellyfish by Cogito Group](https://www.g2.com/products/jellyfish-by-cogito-group/reviews) Jellyfish is designed to simplify the creation and management of digital credentials.

Developed by PKI Solutions, it helps IT and security teams stay ahead of issues by continuously watching over critical components like Certificate Authorities (CAs), Hardware Security Modules (HSMs), and certificate templates. One of the standout features is its “Is-Alive” capability, which checks the health and responsiveness of key PKI elements such as CAs and OCSP responders. This ensures that services are operational and can alert teams to potential problems before they escalate. PKI Spotlight also offers a comprehensive inventory of CA, NDES certificates, Certificate Revocation Lists (CRLs), and OSCP responders tracking their validity and providing proactive renewal alerts. This helps prevent unexpected expirations that could disrupt services. For organizations using multiple HSM vendors, PKI Spotlight provides unified monitoring across different platforms, including Entrust (nCipher) and Thales (Luna). This consolidation simplifies management and enhances visibility into the performance and health of these critical security devices. Security posture management is another key aspect. PKI Spotlight detects over 100 best practices, misconfigurations, and vulnerabilities, such as those identified in the SpecterOps Certified Pre-Owned report, and alerts teams to potential threats like the PetitPotam attack. This proactive approach helps organizations maintain a strong security stance.
