Cisco OpenDNS (Domain Name System) is an American corporation brought by Cisco in August 2015.

Along with DNS services, OpenDNS offers phishing protection and content filtering, which protects users from potentially hazardous websites (helps users search for required information on the internet).

Moreover, open DNS also provides security to the cloud.

Cloudflare relies on a secure CDN (content distribution network). It is also an American firm that provides web security. Cloudflare is a secure network between the user on the internet and the website host.

In other words, it acts as a reverse proxy that protects users’ websites from hacking and dangerous websites.

What is Cisco OpenDNS?

Cisco OpenDNS is a domain name service that makes it easier for users to access online resources. We couldn’t access our favourite and essential websites without DNS.

Generally, we surf multiple stuff online by visiting different websites with unique DNS.

We accidentally land on fraud sites while surfing the internet, which are exact clones of the actual network sites in appearance. However, hackers design and develop these sites to steal users’ personal information.

To avoid the problem of accidentally reaching the fraud website, David Ulevitch created OpenDNS and sold it to Cisco company in 2015.

The idea behind open domain name service is to provide security to internet users by blocking suspicious network sites.

The goal is to safeguard users from phishing attacks (hackers send fraud and duplicate text to people to trick them into acquiring their sensitive information).

The simple principle behind OpenDNS is content filtering (blocking the content that is unwanted or suspicious). Millions of people utilize Cisco OpenDNS to safeguard their residential networks, while Cisco Umbrella is used for businesses.

There are around 24 centres of Cisco OpenDNS worldwide. With time, this system has become much wiser in defending against hacker attacks.

What is Cloudflare?

Cloudflare is an American company that provides internet security services created by three professionals in 2009. It was launched in an online newspaper called TechCrunch to make people aware tech-savvies of this technology.

Cloudflare is a reverse proxy between the end-user and the website, improving performance while protecting it from dangerous viruses. In other words, it means protecting web traffic from a suspicious third party.

The web protocols supported by Cloudflare are SPDY (speedy networking protocols), HTTP/2 (hypertext transfer protocol), and QUIC, which are responsible for transferring data to the same network.

When anybody lands on our website, he will directly have access to our data present online. Cloudflare is installed between the domain and the host to prevent direct access.

If a website owner has purchased the Cloudflare service, their traffic (whether suspicious or legitimate) will land on Cloudflare’s server and subsequently on the website without tracking the IP address.

There are different data centres established according to geographical location.

So, the website gets connected to the nearest centre for establishing the Cloudflare services that are free and premium.

One who handles many websites must use this technology to manage the Name problem servers because Cloudflare also takes DNS.

Creating a Cloudflare account to avail of its beneficial services to protect our site is easy and simple. After that user-friendly steps, we can add our site to Cloudflare.
