A firewall controls traffic between networks, users, remote connections, and internet services. Effective management includes design, secure configuration, updates, monitoring, documentation, and periodic rule review.
Why it matters
What business leaders should understand
Installing a firewall is not a one-time security project. Business changes, new vendors, remote work, aging firmware, and temporary rules can weaken protection over time.
The right response should reflect your environment, data, vendors, risk, and operational priorities. Use this guide as a practical starting point, then validate important decisions with the people responsible for your technology, cybersecurity, legal obligations, and insurance coverage.
