The Differences Between Traditional and Cloud-Based Firewalls
As more and more businesses move their operations online, it’s become increasingly important to protect ourselves against digital threats. Cyber criminals are constantly coming up with new ways to exploit weaknesses in our systems, steal data and wreak havoc. To combat these threats, firewalls have become a staple component of any modern security infrastructure.
Traditionally, firewalls have been hardware-based appliances that sit between a company’s internal network and the outside world. These devices monitor incoming traffic, checking that it meets certain criteria before allowing it through to the sensitive inner network. However, as businesses increasingly move into the cloud, with employees working remotely and data being stored in distributed locations around the world, traditional hardware-based firewalls are starting to show their limitations.
Enter cloud-based firewalls. These innovative solutions leverage the power of cloud computing to provide a more agile and responsive security environment for businesses of all sizes.
So what are the key differences between traditional and cloud-based firewalls?
Firstly, let’s consider cost. Traditional firewalls can be expensive pieces of kit that require specialist expertise to set up and maintain. In contrast, cloud-based solutions offer a much more affordable alternative – with many charging on an affordable pay-as-you-go model based on usage rates.
Another big difference is scalability. As your business grows or changes shape over time – for example by adding remote workers or opening new offices – you need your security infrastructure to adapt accordingly. This is where cloud-based firewalls shine – they can easily be scaled up or down depending on your needs without requiring substantial investment in new hardware.
The other primary distinction between traditional and cloud-based approaches lies in their approach towards customization capabilities. With traditional firewalls being proprietary solutions developed by manufacturers such as Cisco or PaloAlto; a company would have little choice but to use the prescribed settings offered out-of-the-box unless they opted for custom expensive programming alternatives , which rarely found traction from small-medium size companies.
In contrast, cloud-based firewalls feature much more flexible customization options. Most providers allow users to configure and manage their security settings via an intuitive self-service dashboard, providing a level of personalisation and adaptability often difficult to come by in the traditional model.
Finally, let’s talk about performance. Security is only useful if it doesn’t interfere with normal operations. Hardware-based solutions can slow down connectivity to outside websites or services, resulting in frustrated employees and lost work hours. Cloud-based firewalls eliminate this problem by minimizing latency through use of distributed networks known as Content delivery network (CDN) , ensuring optimal speeds without compromising on security.
In conclusion, both traditional and cloud-based firewalls offer valuable protection against digital threats. However, for companies operating in today’s fast-paced business environment, the benefits of cloud-based security are increasingly clear-cut: they’re cost-effective, scalable and highly customizable whilst creating minimal disruption to workplace productivity- going above and beyond what their hardware counterparts could ever deliver.
