Despite their issues, firewalls and VPNs still provide important protection when used properly.
A firewall can block harmful traffic and protect against specific attacks, especially when kept up to date.
A VPN can hide and protect data from hackers on public networks, like in airports or cafes.
Together, they form a strong first layer of defense for businesses and individuals.
However, relying only on firewalls and VPNs is no longer enough to stay safe from modern threats.
