The Washington region could hit the billion-dollar mark in cybersecurity venture funding in 2016. Jonathan Aberman, managing director of Amplifier Ventures, a seed and early-stage venture capital fund based in McLean, said big fourth-quarter investments in cybersecurity companies helped boost overall venture funding in 2015 – and will continue to grow in 2016. He said the Washington region, a growing center for cybersecurity business and research overall, will see more big deals in 2016.
