Overview
Portnox Cloud
Portnox Cloud helps you secure your entire network infrastructure without the headache of managing on-site hardware or complex appliances. You can gain full visibility into every device connecting to your network, whether they are managed corporate laptops, personal mobile devices, or unmanaged IoT hardware. By moving network access control to the cloud, you eliminate the need for local servers and simplify the way you manage authentication across multiple locations.
You can enforce strict security policies and automate responses to non-compliant devices in real-time. The platform integrates directly with your existing cloud identity providers like Microsoft Entra ID or Google Workspace to streamline user onboarding. Whether your team is working from a central office or a home coffee shop, you can ensure only authorized users and healthy devices access your sensitive digital assets.
Tenable Nessus
Nessus helps you identify and fix security vulnerabilities before attackers can exploit them. You can scan your entire environment—including cloud instances, web applications, and traditional network hardware—to find missing patches, software flaws, and configuration errors. It provides a clear view of your attack surface so you can prioritize the most critical risks to your business.
You can choose between different versions depending on your needs, ranging from a free version for educators and students to professional and expert versions for security consultants. It simplifies the complex task of vulnerability assessment with pre-built templates and automated reporting. Whether you are securing a small office or a complex hybrid-cloud environment, you can rely on its extensive plugin library to stay protected against the latest threats.
