The companies are Fidelis Cybersecurity and Mandiant. They base their analysis on five malware samples used in the hacking attack. Fidelis executive Michael Buratowski says, “Based on our comparative analysis, we agree with CrowdStrike and believe that the Cozy Bear and Fancy Bear…groups were involved in successful intrusions at the DNC [Democratic National Committee] . […] The malware samples matched the description, form and function that was described in the CrowdStrike blog post. In addition, they were similar and at times identical to malware that other [research firms] have associated to these actor sets.”

However, the Washington Post reports, “It is also possible, researchers said, that someone else besides the Russians were inside the DNC’s network and had access to the same documents.” (The Washington Post, 6/20/2016) 

A law firm reviewing the DNC attack, Baker & McKenzie, has begun working with three cybersecurity companies to review CrowdStrike’s findings. Fidelis Cybersecurity is one of them, along with FireEye and Palo Alto Networks, Inc. (Bloomberg News, 6/21/2016) (Fidelis Cybersecurity, 6/20/2016)
