Facebook is to use RiskIQ's monitoring system to keep its hundreds of millions of social networkers away from malware and spiked advertising attacks.
RiskIQ will scan for risks and threats, and Facebook hopes that this early monitoring and filtering will prevent security breaches in its services.
Such problems are on a large scale. Google, for example, blocked a staggering 524 million 'bad ads' and removed 250,000 sites for spreading malware in 2014 alone.
"RiskIQ helps Facebook detect and block threats planted in third-party ads that violate our policies and can put people at risk," said Jennifer Henley, Facebook's director of security operations.
"The additional insight they provide helps us protect the integrity of our global network and create a trusted environment for the people on our platform."
Facebook comes under attack often. FireEye's director of technology strategy, Jason Steer, told V3 last year that the network is a "prime" target.
"Sites like Facebook and LinkedIn are prime sites to look for and target people," he said.
RiskIQ has a strong user footprint and boasted about its position in the financial industry.
"We are extremely proud that Facebook chose RiskIQ to help protect their users from malicious and fraudulent activity," said Elias Manousos, chief executive of RiskIQ.
"Our platform's global visibility into the user experience on Facebook allows us to provide them with the intelligence they need to keep users safe every day."
"A larger number of providers increases the chances that malware will get caught and cleaned up, which will help people on Facebook keep their information more secure," said the company in a post on the firm's engineering blog late last year.
"Together, these systems will help us block malicious links and harmful sites from populating the news feeds and messages of the 1.35 billion people who use Facebook."
