Yahoo hired Bob Lord as the company's new CISO, according to a blog post by Jay Rossiter, SVP, product and engineering, science and technology at Yahoo. Lord will lead Yahoo's cybersecurity group, called the Paranoids.
Lord was previously CISO in Residence at Rapid7, the Boston-based cybersecurity firm that held a public offering in July. He is an advisor to the Washington, D.C.-based Council on Cybersecurity, the successor organization to the National Board of Information Security Examiners.
He was Twitter's first security hire, where he was director of information. Lord led the social media giant's information security program and “established Twitter's efforts in compliance, application security, product security, and information security,” according to the blog post.
The hire is the third executive to have held that role in the past six months. In March 2014, Alex Stamos joined Yahoo , replacing Justin Somaini. Fifteen months later, Stamos departed Yahoo to join Facebook as chief security officer in June 2015. Next, Ramses Martinez, previously Yahoo's senior director of intelligence, investigations and response, was named interim CSO. Martinez joined Apple's information security team last month.
