The deal closed on Monday, but terms were not disclosed.
FireEye, which started out with an end-point protection product, has been seeking to expand the range of security products and services it offers as cybersecurity has become a growing concern for companies.
Invotas, based in Alexandria, Virginia, has a single product, its Security Orchestrator. The platform is designed to take in information from a range of security products from different vendors and automate responses when an incident is detected.
FireEye said in a news release that many organizations must manually process information from different data sources, which creates an inconsistent workflow.
It plans to use Invotas' technology as part of its partnership with ForeScout, which develops software that detects new devices joining a network and manages them.
The acquisition is the second one FireEye has announced in the last two weeks. On Jan. 20, it acquired Texas-based iSight Partners for US$200 million, a deal that executives said will give it stronger intelligence on cybercriminal and hacking groups before they strike.
In early 2014, it bought Mandiant, a computer security company that specializes in investigating cyberattacks. The victims of some of the largest data breaches in memory, including Target, have retained Mandiant's services.
In November, FireEye blamed an agreement between the U.S. and China to not support the hacking of corporations as reducing the demand for its services, causing its share price to fall, according to Reuters.
