Don't forget about firewalls in 2022

When working in an office was the only option most of us had, making the case for a firewall was an easy sale.

The office, along with all its digital assets, was a company's castle. And the firewall was the moat meant to keep out the invaders.

Times have changed.

Working in the office isn't uncommon. But it's no longer the only option employees have. Remote and hybrid work environments mean businesses now have more fronts to cover to maintain solid security.

Even if employees work exclusively on site, innovations like the cloud mean companies are communicating with more external services than they did 20 years ago.

Rethinking the "castle and moat" analogy

Perhaps the castle analogy no longer works. Maybe it would help to think of your office as your company's homebase. Business can happen anywhere. But you still want to protect the headquarters, the place your employees call home. Even if they visit only once every blue moon.

A firewall no longer covers as much attack surface as it once did. But firewalls still have a place in modern security.

Firewalls still serve a purpose

The threats firewalls protected against in decades past still exist. Those threats still need to be addressed and protected against.

Also, firewalls still include crucial features such as:

  • Intrusion Detection System (IDS)

  • Intrusion Protection System (IPS)

  • Port filtering

So the firewall still has a place in the 21st century.

The unfortunate truth is that businesses now have more attack surfaces to worry about. Businesses should not be thinking about other security solutions in place of firewalls—but in addition to firewalls.
