IBM Security has completed the acquisition of Resilient, as part of the company’s expansion in the incident response marketplace. Financial terms of the agreement have not been released.

The company had announced its plans to acquire Resilient in February, alongside the launch of its X-Force Incident Response Services. Resilient’s incident response system allows customers to automate and orchestrate the many processes needed when dealing with cyber incidents. The new services include a remote incident response capability to help clients map how a breach occurred and take action to shut it down.

“The combination of Resilient’s people – top thought leaders in the incident response marketplace – and their technology is a differentiating addition to our security business,” said Marc van Zadelhoff, General Manager at IBM Security. “Our investments in threat detection and prevention have helped us move into a leadership position in the security market. With Resilient, we’re expanding the capabilities we bring to customers, helping them manage the complexities in resolving security incidents, including the coordination of teams, best practices, and reporting.”

The company have claimed by combining Resilient Systems’ Incident Response Platform with IBM’s QRadar Security Intelligence Incident Forensics, BigFix, X-Force Exchange and other Incident Response Services, it will be able to offer increased speed in dealing with threats.

IBM has been quietly building its security business over recent years through various acquisitions and company hires. In the last three years, the company has bought a number of security specific vendors including CrossIdeas, Lighthouse Security Group and Trusteer, the latter was rumoured to be around the $1 billion mark. The company now claims to be the largest cloud and cyber security vendor in the market, exceeding $2 billion in revenue and hiring more than 1000 security professionals in 2015, as well as holding than 3,000 security patents.

“The Resilient team is delighted to be joining IBM Security,” said John Bruce, Resilient’s CEO, “Together, we will be a powerful force helping organizations to manage the evolving security challenges that they face. With the scale of IBM research, development and investment behind us, we’re excited about the possibilities for innovation and to engage with new clients around the world.”
