The Case for Collective Defense

Organizations are on pace to spend more than $120B in 2019 on cybersecurity, yet industries continue to experience more cybersecurity breaches and incidents than ever before. Collective Defense is a different approach to cyber security, but it is a necessary and worthwhile effort — one that will protect your own company and help secure your industry and the nation.

Cyber Assessment Test

The Cyber Assessment Tool allows you to test your current detection capabilities against some of the most prominent cyber threats. You can see the results of the simulations in real time and download a report including attack indicators. By searching for the given indicators in your security systems, you can determine which of the emulated attacks could pose a threat to your network in a real-world scenario.
