And Seattle, home to Microsoft, is top of the list.
The company came to its results by using its own data and independent research firm Sperl Bestplaces to come to its conclusions.
Here are the top 10:
- Washington DC
- San Francisco
Seattle is top, according to the report, for cyberattacks and potential infections and online behaviour that can lead to cybercrime, like online shops, online banks and wi-fi.
As Symantec rather disingenuously points out, many of the cities are considered the most tech-savvy cities in the USA.
Marian Merritt (pictured), a Symantec employee in charge of internet safety, said Detroit was the least risky online city. El Paso and Memphis also aren’t very risky. But these cities also don’t have fantastic access to the internet, and don’t spend much on computer kit, she said.
Needless to say, Symantec has an agenda here. It wants you to buy Norton 360 so you’re safe, and it’s making money out of insecurity, even if you live in Seattle or Boston.
