NAC technologies

NAC, or Network Access Control, is a security technology that manages who can access a computer network and what they can do once inside. It verifies devices and user credentials before granting access, ensuring they meet security policies—like having updated antivirus software or proper permissions. NAC helps prevent unauthorized or risky devices from connecting, reducing the chance of security breaches. Think of it as a gatekeeper that checks identities and security standards before allowing entry, keeping the network safe and compliant.
