The free service from Singapore's Vodien Internet Solutions is called Site Sentry and alerts site owners about anything suspicious going on with the web pages.
The real-time service and parallel daily updating facility is billed as quickly alerting all users and administrators if there is any suspicious activity going about in the digital realm.
According to Vodien, 'too late' can mean that critical data has been stolen. `Too late' can also mean a loss of some or all of its functionality.
John Jarvis, the ISP's director, said: "We wanted to give our customers piece of mind. In fact, we are quite familiar with this problem, and it is always a mad rush to trace to problem, squash it and reset everything", he said.
"Sometimes we have to upload a backup of the website, which means that all the latest updates and changes can be lost - and that is just unacceptable", he said.
Jarvis says that the problem has always been the delay between someone noticing something is wrong, or the various anti-virus and anti-malware softwares finally kicking in during a scheduled scan.
It could, he explained, even go unnoticed for days till a customer complained - which, in the world of business, is way too late.
This is where Site Sentry enters the frame, detecting files that have been changed on any website and comparing them to a previous state.
The service is then billed as emailing the administrator and owner of the site with a list of files that have been tampered with, or are missing.
By issuing daily email alerts, Vodien claims that site owners will know quickly if something or someone had illegally breached the security of their website.
