How effective are firewalls and VPNs against modern cyber threats?

Firewalls and VPNs are foundational tools in defending against modern cyber threats, but their effectiveness depends on proper configuration and usage. Firewalls filter incoming and outgoing traffic to block malicious access, while VPNs encrypt data transmission, ensuring privacy over public networks. However, they are not foolproof. Advanced threats like phishing, zero-day attacks, and insider threats can bypass these defenses. That's why individuals and organizations must combine these tools with endpoint security, threat intelligence, and regular updates. Enrolling in Cybersecurity training and placementprograms helps professionals stay updated on evolving threats and learn how to implement comprehensive security strategies beyond just firewalls and VPNs.
