Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Remember the days when you were a kid, and one of the most exciting things that would grasp your interest at an office would be a fax machine?

Well, what if I tell you that the fax is still widely used and has been serving its purpose since 1843? It may seem a bit weird if someone asks you to fax them, but sending a fax has numerous benefits, and is proven that it’s not a thing of the past. It is still used in various industries like healthcare, government offices, finance, and legal departments.

With the advancement of technology, fax has evolved into a better version, and now you can send fax via the internet as well through several mediums.

How does internet fax work?

All of us know that faxes are usually sent by a fax machine, but modern times call for modern solutions, so it was only a matter of time before fax went online. You can now easily fax documents via the Internet using various services available.

In simple words, internet fax uses the same technology as machine fax. The only difference is that it uses a web interface to transmit communication.

Generally, it is easier to fax, as you can transfer information easily with the help of a unique fax number, and that can turn out to be quite convenient in the process. However, internet fax is flexible, even faster, and cost-effective when compared to machine fax.

Some of the many reasons for opting for online faxing are:

  • No need to print faxes, thus eliminating physical paper completely 📝
  • Convenient and time-efficient ⌚
  • Sensitive information is kept private and secure because you can receive it directly in your inbox 📧
  • Most faxing services online have proper encryption in place to protect your data at all times 🔒

To get started with it, all you need is an internet connection, an email account, and a fax service provider, which we’ll be going through in this list. Let’s jump right into it.
