What are the best network access control (NAC) solutions for multi-location enterprises?

Open Source: in my opinion, PacketFence and pfSence are the most advanced NAC solutions that have 802.1X support, layer-2 isolation of problematic devices, and also integration with the Snort. Commercial: FortiNAC Could be a total solution for Network Access Control.

For multi-location enterprises, top NAC solutions include Cisco Identity Services Engine (ISE) for centralized policy management and scalability, Aruba ClearPass for flexibility and strong wired/wireless support, Fortinet FortiNAC for robust integration and automation, and Palo Alto Networks Prisma Access for cloud-based security and scalability. ForeScout CounterACT offers agentless visibility and continuous monitoring, while Extreme Networks ExtremeControl provides centralized management and flexible deployment. These solutions are scalable, integrate well with existing infrastructure, and offer strong security features.

Best NAC solutions depends upon vendor we use. If you have full of cisco switches go with Cisco ISE. Fortigate switches can be controlled by Fortigate Controller . HP aruba using clear pass. Instead of messing up with multivendor . Single vendor approach for management is easy to manage. Enterprise level i would suggest Cisco else fortinet would be viable option depends upon the budget.

I have used Fortigate switches as a NAC for enterprise level I suggest using Fortigate or Cisco vendors solutions for multi-location

Uno de los mejores enfoques de seguridad es el MFA( en caso de empresas con distintas sucursales donde los usuarios rotan entre las mismas), ya que las contrase?as por más complejas que sean son más vulnerables, y en caso de ser necesario y viable, incluir controles biometricos para los accesos(fingerprint, reconocimiento facial, etc) ya que incluso el Endpoint más potente queda vulnerable si no hay una restriccion correcta de los permisos a los usuarios. También limitar los puertos de accesos a un cupo limitado de dispositivos a traves de los mac address evitará accesos no permitidos y un control más extricto.

For multi-location enterprises, the best Network Access Control (NAC) solutions are those that offer comprehensive security features, scalability, and ease of integration with existing infrastructure. Key capabilities to look for include real-time device visibility, robust policy enforcement, support for diverse device types (including IoT), and centralized management to ensure consistent security across all locations. Solutions that provide agentless deployment, detailed device profiling, and automated threat response are particularly effective. Additionally, cloud-native NAC solutions offer enhanced scalability and simplified management for distributed environments, ensuring robust protection and compliance across the enterprise network

As I know that Cisco ISE and Aruba ClearPass is the best solutions for large enterprise however Forescout Platform and Fortinet FortiNAC are also excellent choices, especially for environments with diverse device types and security needs.

Al integrar politicas a una infraestructura de red, comprende varios temas, como lo es la seguridad administrada, ciberseguridad, control y monitoreo de la red, estos factores son muy fundamentales para mantenernos blindados de cualquier ataque, al estar vulnerables perdemos gestion de nuestra red, lo que conlleva a un colapso fortuito de nuestra infraestructura, tambien es indispensable educar al usuario puesto que tambien es una herramienta muy importante que el usuario se encuentre instruido puesto que el seria el primer filtro ante un ataque en la red.

1. Authentication: When a user or device attempts to connect to the network, they are prompted to authenticate themselves. This could involve entering a username and password, providing a digital certificate, or using multi-factor authentication methods. The NAC (Network Access Control) Extensible Authentication Protocol (EAP) is a framework that allows for different methods of authentication to be used in network access control systems. EAP provides a standardized way for diverse devices and systems to establish mutual authentication and negotiate encryption keys. It's commonly used in Wi-Fi networks, VPNs, and enterprise networks to ensure secure access.

When it comes to network access control (NAC) solutions for multi-location enterprises, several options stand out. Let's explore some of the top choices: 1. Cisco Identity Services Engine (ISE): -Best for Large Enterprises - Features - Support - Licensing 2. Forescout Platform: - Best for User and Device Diversity - Features - Scalability - Integration - Support 3. Aruba ClearPass: - Best for Small and Medium-Sized Businesses (SMBs) - Ease of Use - Features -Licensing 4. Fortinet FortiNAC: - Best Cloud-Based NAC Solution - Features - Licensing 5. Extreme Networks ExtremeControl: - Best for Integrating NAC Solutions - Features - Scalability - Support

Before choosing a security framework or approach, the organization needs to establish clear governance. This governance should specify scenarios such as bring your own device (BYOD), guest policies, roaming users, etc., which will be incorporated into a network architecture. Within this architecture, frameworks, approaches, and methodologies will be chosen to form the foundation that will deliver the governance cornerstone.

Cisco ISE is one of the best solution. It will not be a cheap solution. As I myself would prefer open source solution. Where there are no boundaries and dependencies. The goal is to make everything accessible securely and should be cost effective. There are other options and customised solutions. It depends upon organisation's budget. Enterprise level organisations could easily afford CISCO solution.
