The Google acquisition wheel has started spinning again, this time by taking over a security startup Impermium, apparently to fight the imposters who exploit the internet for illicit activities.

Google, the world leader in internet search, is focusing on making the web a safer place for its users. The web giant has acquired a cyber security service Impermium that will use its expertise to keep the bad guys away. Cyber security is one of the biggest concerns in the digital world. Hackers have targeted popular services like Skype, Snapchat, and several medial organizations like CNN, TIME, Washington Post and many others.

 Internet is more than just a luxury in today's world where most daily works depend on the wide world of web.

Thousands of millions of users get on the internet for various purposes. But to what extent are those users away from malicious hackers? "By joining Google, our team will merge with some of the best abuse fighters in the world," Impermium CEO and co-founder Mark Risher said on the company's website. "With our combined talents we'll be able to further our mission and help make the Internet a safer place. We're excited about the possibilities."

Impermium was founded in 2011 through generous seed funding from Accel Partners, AOL Ventures, Archimedes Capital, Charles River Ventures, Embarcadero Ventures, Freestyle Capital, Greylock Discovery Fund and Morado Ventures of up to $1 million, Vator News reported. The company further raised $8 million funding from Highland Capital Partners, The Social+Capital Partnership and Freestyle Capital in November, 2011. The startup controls spam and fights web abuse and online fraud.

Google did not officially announce the acquisition news, but Bradley Horowitz, Google's vice president of product for Google+, welcomed the Impermium team through his Google+ account.

"Google's spam and abuse teams are industry-leading and world-class.  Impermium should fit right in," Horowitz wrote.

Besides this, Google also acquired Nest, a smart smoke and thermostats maker for $3.2 billion in cash. The acquisition came as a part of its move to expand its reach into the connected home market.
