We received an e-mail recently asking:
Why do we scan and analyse every link - and surely it's not in real time?
The answer's to the first bit is quite simple:
Would you cross a road on the basis it was safe at one point over a month ago?
Quite. We think the same way about visiting websites - as they can and do change as often as road traffic does - sometimes safe, sometimes not ...
So we always 'look both ways' every time before 'crossing the road' to visit a site. The only way to do this properly is to scan and analyse every time.
We put every search result through a whole heap of ScanSafe processes, multi-layered malware scanning, dynamic heuristic analysis, multiple list verification and content investigation - amongst other analysis processes - it's what it takes to be safe on the web today!
And for the real time question...
Scandoo icons are always generated in real-time based on real-time analysis - We can do this in real time thanks to the really clever system architecture and parallel processing technology. You can read more about it on ScanSafe's website. The service most of this technology came from is a business service that's a secure web proxy to access the internet through - literally scanning web traffic so quickly that users can't tell if they are going straight out to the internet or being scanned.
Mighty clever stuff if you ask me!
