For cybersecurity professionals who know that the industry has no shortage of threat data, context is the lever that turns threat data into threat intelligence.

As 2016 comes to a close, the time is right to look back at the year to reflect on those security lessons we learned and to identify emerging trends.

The Court of Justice of the European Union (CJEU), the highest constitutional court of the EU, has effectively slapped down the UK's new Investigatory Powers Act.
