Secure cutting-edge web app development

Web app security is at the heart of the apps we develop. We take your data security very seriously!


What is a web app?

A web app is software that resides on a remote server and is accessed over the Internet through a browser.

Web apps are the perfect way to allow your stakeholders to perform tasks which you may have previously carried out on traditional installed software as there is nothing to download or install and updates are completely hassle-free. All you need is an Internet connection and you can use these web apps from anywhere and on any Internet-connected device (e.g. PC, Mac, smartphone or tablet).

Web apps differ from mobile apps (i.e. those you download from Apple's App Store or Google Play) as mobile apps are developed for a defined platform (e.g. iOS, Android) and installed on the actual phone/tablet rather than being installed on a server and accessed through a browser.

You probably use web apps on a daily basis without even realising it. Using Gmail or Hotmail or online banking means you are using a secure web app!

We have developed bespoke cutting-edge web apps for lots of organisations ranging from multi-national blue chip organisations, large public sector organisations and SMEs.

Web app security

Most web app hacking attacks happen by means of cross-site scripting (XSS) or SQL injection attacks. This is usually due to the poor coding practices of the relevant web app developers.

We develop our web apps assuming they will be targeted by hackers hence we ensure our custom-made web apps are coded in a way that protects them from such hacking attempts. We keep abreast of current hacking trends and engage in "white hat" hacking attempts and "penetration testing" of our apps to help keep them secure.

Web app data encryption

We can make sure that all data captured and stored on the web apps we develop is encrypted with the strongest cryptography available to protect your data.

We will generally encrypt data using cryptographic algorithms that meet the Advanced Encryption Standard (AES) which is a symmetric block cipher used by governments to protect classified information.

AES is made up of block ciphers which encrypt and decrypt using secure cryptographic keys with government "Top Secret" information requiring 192-bit or 256-bit cryptographic key lengths.

Do you have an example of a secure web app?

Of course we do, for example we have developed a number of web apps for Woodhouse Sixth Form College in Finchley, London, such as:

  • Mobile-friendly website
  • Student application and management system
  • Job vacancy application and management system
  • Student interview management system
  • Reference management system
  • Virtual learning environment

Web App Developer has been our development partner for both our website and virtual learning environment since 2004. The quality of service has been consistently exceptional in every way. I would be very happy to recommend them for any development and as a highly reliable long term partner as well as for short term projects.
