The cybersecurity market further accelerated in the fourth quarter, according to an analyst note Tuesday from Bank of America Merrill Lynch, driven by higher demand for network security products like firewalls and protective tools meant to stop newer types of malware.

The total market for network security products in 2018 grew 12.6 percent compared to 2017, according to analysts Scott Casher, Daniel Bartus and Tal Liani. It was "the fourth consecutive quarter of double-digit growth," and "the strongest year since we began tracking the market in 2012," the analysts wrote.
